How to make a pipe bender for a profile pipe

Homemade pipe bender for profile pipe

Industrial samples of pipe benders have a sufficient number of differences from similar devices created by handicraft methods. Compact models of this equipment are available for purchase, supplemented with manual drives if you intend to work with a small-sized profile pipe.

As for more serious work, when bending pipes from 3 inches is expected, hydraulically driven machines are used. An industrial tool of the type in question is relevant only if the work is of a corresponding scale, that is, it is unlikely to be suitable as home equipment.

The industrial production of pipe benders involves the production of two modifications of devices, where some are created in a mobile version, accessible for carrying, and others are created in a stationary version. Pipe benders connected to electricity are more convenient to use. They provide the desired bend radius in accordance with a certain angle without deforming the profile.

If you are planning to carry out pipe bending work at home, then you need to take into account certain nuances:

• The manual tool is equipped with a spring element, with the help of which the pipe configuration is changed;
• a segment tool makes it possible to bend a pipe by stretching it around the segment of the equipment used;
• The mandrel tool allows you to bend only thin-walled pipes to a fairly small radius using special guides.

How to make your own pipe bending machine

To make a machine for bending a profile pipe with your own hands, you must remember that the final product must be extremely simple and fulfill its function.

1st method

To make and use a bending machine for a profile pipe, you need to prepare two pieces of channel, two cuttings of fingers that are part of the tractor tracks, and four corners.

To bend the workpiece you will need a jack capable of developing a force of 5 tons or more. In this case, it will require its modernization by installing a steel platform on the retractable rod, for the manufacture of which a worn-out pulley can be used, having a “stream” width comparable to the pipe profile. In this case, arranging a hydraulic drive involves cutting off half of the pulley and drilling a seat in it for the jack rod.

The frame of the future machine is assembled from corners fixed to a steel plate by welding. A total of four corners are used, having a flange from 60 to 80 mm, at the upper ends of which two channels are fixed by welding. To adjust the bend angle, it is necessary to have symmetrical holes in the walls of the channels that need to be drilled.

To bring the finished machine to its starting position for work, it is enough:

• insert the axles (fingers) into the holes obtained in the channels and fasten the rollers to them as stops for the workpiece;
• raise the jack platform to such a level that the workpiece can pass into the gap formed;
• install the workpiece in the machine for the profile pipe and create the required bend using a jack, using its functionality.

2nd method

A homemade pipe bender for a rolled profile pipe implies that the workpiece will be laid on side rollers and pressed on top by a third one. After fixing the pipe in this position, all that remains is to drive the shafts through a chain transmission to achieve the desired bend.

To make a machine for rolling profile pipes you will need:

• make rollers and cages for placing bearings, which can be achieved by turning to the services of a professional turner. In total, the design of the created device provides for the presence of three shafts, where one is mounted on springs, and the others are fixed in the sides of the frame;
• prepare the shelf. To do this, you will need a channel (50 mm), from which you will need to assemble a rectangle 100 by 30 cm. Then in the assembled shelf you should make holes for the shafts and cut the threads necessary to implement the ability to change the force of the pressure shaft;
• assemble a structure from existing parts by welding;
• hang the shelf on springs, and connect the side shafts with a chain using sprockets, welding a handle onto one of the shafts;
• install the jack in such a way that its use allows you to change the pressing force.

Attention! It is problematic to manufacture a functional rolling pipe bender without the appropriate calculations and drawings. However, not everyone has the necessary knowledge for this, so it is best to use ready-made documentation.

Making your own pipe bender for a profile is a completely feasible task that must be correlated with certain goals.

If you plan to carry out such work only as a one-time event, then you can assemble a wooden structure that is quite capable of withstanding a short period of use.

Otherwise, when it is planned to manufacture pipes with one or another bend on an ongoing basis, it is advisable to acquire a stationary unit of a more complex and reliable design.

To assemble a stationary device required for bending pipes, you must do the following:

• mount a metal frame, connecting its elements using bolts and welding;
• install the axles and shafts on them in accordance with the existing drawing, observing the placement levels: two above the third;
• assemble the chain drive used to power the machine, which will require not only a chain, which can be borrowed, for example, from an old motorcycle, but also three gears;
• attach a handle to one of the shafts.

Assembling a simple pipe bender

By following the instructions below, you can make a pipe bender for a profile pipe with your own hands for a cross-section from 10×10 to 25×25 mm at an angle of up to 180 degrees.

The proposed design is simple, and for its manufacture you will need the following set of materials:

• fastening strip;
• square profile required for making the rotation handle;
• two rollers, where the diameter of the first is 65 mm, and the second is 173 mm;
• an axis equipped with an M14 thread at the end;
• nut M16, washer C

To manufacture the fastening strip, metal with a thickness of 7 mm or more can be used. In this structural element it is necessary to drill a hole (30 mm) to install the axle for the roller, 4 sockets (8 mm) for M6 studs and holes for bolts.

A square profile (36×36 mm, wall thickness 4 mm) is suitable for making a handle that drives the machine. To attach this element as a lever to its inner end, you need to weld two plates and make holes (30 mm) in them, focusing on the bolts that secure the rollers.

The pipe bender is assembled in compliance with the following procedure:

1. The mounting plate is secured to the workbench using M8 bolts. In this case, the stability of the workbench should be ensured in order to eliminate the possibility of it shifting while bending the workpiece.
2. A large roller, secured with a nut, is mounted on the rotation axis fixed in the mounting strip.
3. The axis holding the small roller is installed and secured.
4. The M6 ​​studs necessary to hold part of the profile while working with it are placed in their places. Mounting plates corresponding to the profile size are mounted on the studs.

In the future, the process of bending a professional pipe assumes that the pipe bender handle will first be moved to the left position all the way, then the workpiece will be installed in the desired position, the bending of which will be ensured by the operation of the machine driven by the lever.

Conclusion

Since making a pipe bender for a profile pipe is quite difficult, we presented 3 different options for its manufacture. One of them should come up.

After you make a pipe bender with your own hands, send it to us by email with a description of the work and we will post it on the website.

Homemade pipe bender for profile pipes – Pipes and plumbing

Bending profile pipes is a fairly common procedure, for which a special device is used - a pipe bender. You can make a pipe bender for a profile pipe with your own hands, or you can purchase it at the construction market or in a store.

One of the simplest types of pipe bender for profiled pipes

Serial devices differ in their operating principles, they may have different types of drives, but operating any of these devices requires some experience. The use of devices manufactured in production conditions is limited by the fact that they are not cheap. A good solution in all such situations would be to independently manufacture a device designed for bending profile pipes, for which you can use improvised means.

Required design elements

The operating diagram of a pipe bender is very simple

To make a pipe bender with your own hands, you can use drawings of various designs. Their choice is determined mainly by what materials you have. Most often they opt for front-type pipe benders, the design of which includes:

• three rollers (shafts), which must be metal;
• drive chain;
• axes of rotation;
• a mechanism that will set in motion all elements of the device;
• metal profiles from which the frame of the device will be made.

Very often, a machine for bending profile pipes is made with rollers made of wood or polyurethane. When choosing such materials, you should take into account the strength characteristics of the pipes that will be subject to bending. If you neglect this requirement, then the working elements of the homemade device may simply not withstand the load and collapse.

To understand how to bend a profile pipe on a homemade device, it is important to understand the technology used for this process. As a rule, pipe benders use the rolling or rolling principle, which minimizes the risk of kinking and damage to the pipe.

To make a bend on a profile pipe using such a device, it must be inserted between the rollers of the pipe bender and turn the handle. The use of such a simple bending device allows you to obtain bends on a profile pipe that fully comply with the specified parameters.

Pipe bender using a jack

To make a simple machine for bending profile pipes, you will need the following structural elements:

• ordinary jack;
• metal profiles and shelf necessary for making the frame;
• springs with high strength;
• shafts in the amount of 3 pieces;
• drive chain;
• a number of other structural elements.

When using such a device, the operation of which can be seen in one of the videos below, the pipe is laid on two side rollers, and a third one is lowered on top of it, creating the required force. To give the pipe the necessary bend, you need to rotate the handle that drives the chain and, accordingly, the equipment shafts.

Option with inverted jack

Pipe bender manufacturing process

To make a device for bending profile pipes, you must perform the following procedures.

• Prepare a reliable frame, the elements of which are connected by welding and bolted connections.
• Using a previously prepared drawing, install the axis of rotation and the shafts themselves, two of which are located above the third. The bending radius of the profile pipe depends on the distance at which the axes of such shafts are located.
• To operate this bending mechanism, a chain drive is used. To complete such a transmission, it is equipped with three gears, and the chain itself can be picked up from an old car, motorcycle or other equipment.
• To operate such equipment, a handle is needed that is connected to one of the shafts. It is through this handle that the required torque is created.

Instructions for making a pipe bender

Making a pipe bender for a profile pipe yourself is not at all difficult if you adhere to the following technological sequence.

• Gears, bearings and rings are placed on the pressure shaft, which are connected to it using a key. First, a drawing of such a shaft, races for bearings and rollers is developed, then these parts are turned, which is best entrusted to a qualified turner. In total, for this device it is necessary to make three shafts, one of which is suspended on springs, and the other two are located on the sides.
• Then it is necessary to drill holes in the rings, which are necessary for making grooves and threading.
• Now you need to make a shelf, for which you use a channel, in which you also drill holes and cut the threads required when installing the pressure shaft.
• After completing the preparatory measures, the entire structure of the equipment must be assembled, for which welding and bolted connections are used. First of all, the frame is installed, which also serves as the legs of the pipe bender.
• The next step is to hang the shelf with the pressure shaft attached to it, for which springs are used. After this, you need to install side support shafts on the homemade pipe bender, on one of which a handle is attached.
• The final touch is to install the jack on the pipe bender.

Some subtleties of installation work:

• the pressure shaft, fixed with keys, is additionally screwed to the shelf;
• installation of the pressure shaft is carried out according to the following scheme: the shaft is installed on a shelf to which nuts for the springs are pre-welded; after the installation work is completed, the shelf is turned over and suspended on the springs;
• the chains are tensioned using a magnetic corner, which is used as a holder;
• when tightening the sprockets, keys are used, which are pre-made from Grover;
• the drive handle for the bending machine is made with a rotating tube;
• The jack on such a homemade device is installed on a suspended platform, for which bolted connections and welding are used.

Manufacturing of hydraulic pipe bender

On the Internet you can find many photos and videos of how to make your own device for bending profile pipes with a hydraulic drive. The process of manufacturing such a pipe bender, equipped with a hydraulic cylinder, injection device and pipe stops, is a rather labor-intensive undertaking.

In the drawing and in the design of such a pipe bender, the following elements can be distinguished:

• hydraulic jack with a lifting capacity of at least 5 tons;
• shoe;
• rollers in the amount of 2–3 pieces;
• powerful metal channel;
• thick metal plates and other parts.

To make the required bend of a profile pipe using a hydraulic device, it is necessary to insert it into the shoe and fix both ends. After this, you need to use a jack, which, with its rising rod, presses on the roller, which acts on the pipe and bends it. Once the required bend angle is obtained, the process can be stopped and the pipe can be removed from the pipe bender by turning the jack handle several times in the opposite direction.

To make your own hydraulic bending device for profile pipes, a photo of which can be easily found on the Internet, you must follow the following procedures.

• Based on the drawing or photo, a structure for mounting the shoe and rollers, as well as the equipment frame, are made.
• A metal plate is attached to the lower platform on which the jack will be installed. After this, such a device is secured with bolts and a drive handle is installed on it.
• The most important thing is to find suitable rollers for the profile pipe, which should tightly grip the working part. If desired, rollers for the profile pipe, which are installed on the channel at the same height, can be made with your own hands. The shoe is installed below the rollers, and their relative position is determined by the required bending radius.
• To fix the rollers and shoe, bolts are used, the holes for which are made according to the dimensions indicated in the drawing.

Methods for bending pipes using a homemade machine

The question of how to bend a profile pipe using a homemade pipe bender is unlikely to confuse you if you read a few more recommendations. Hydraulic machines can be used to successfully bend profile pipes made of different materials, as well as thick-walled products. This operation can be performed using either a cold or hot method, which involves preheating the pipe section.

Thus, a manual hydraulic bending machine can be used to influence the pipe in two ways:

Another variation with a jack

Cold bending is the simplest bending method, which is used for pipes made of plastic materials. The subtlety of this process is to fill the pipe before the flexible pipe with sand, salt, oil or cold water. This allows you to get a better bend without significant deformation of the pipe.

If you are interested in the question of how to properly bend a profile pipe with thick walls or made from materials of increased rigidity, then the answer to this question is to use the hot bending method.

Useful tips

The question of how to bend a profile pipe as accurately as possible and without unnecessary labor costs will be answered by several useful tips from qualified specialists.

Homemade pipe benders for profile pipes

Craftsmen and amateurs who manufacture various kinds of external structures sooner or later need to use curved elements from a profile pipe.

There are special machines for bending this type of rolled product, but they are quite expensive.

What to do if the need for a bent profile arises infrequently, but you want to save money? The answer suggests itself - you need to make a pipe bender for the profile pipe with your own hands. We suggest you figure out how to approach solving this issue.

Homemade manual profile bender

Why for a profile pipe?

Let's agree that now we are only talking about a profile pipe - that is, one that does not have a round cross-section, but, as a rule, square or rectangular, less often oval. Such rolled steel is most often used as reinforcement in the construction of various types of structures, due to its following characteristics:

• less weight (and, therefore, price) compared to all-metal elements;
• a form that allows compact storage, transportation and laying of corrugated pipe, especially on flat surfaces;
• possibilities for simple and convenient installation;
• increased strength;
• resistance to deformation.

Sections of profile pipes

And if you have chosen a profile pipe, but want to make a structure with a rounded shape, for example, a greenhouse, gazebo, canopy, arch, then the straight profile will have to be bent using a special machine. But since the condition of our experiment is minimal monetary costs, then for work we will take a homemade pipe bender for the profile.

What is a pipe bending tool?

A pipe bender is a capacious and logical name for a profile bending machine on which a profile pipe is evenly bent so that it does not flatten at any point in the bend. The cross-sectional opening retains its configuration, and the profile itself takes the shape of an arc.

Depending on the type of drive, the machines used to bend corrugated pipes are:

• electrical;
• hydraulic;
• mechanical (manual).

Electrically driven mechanisms are, as a rule, professional equipment and are capable of bending many meters of profile in a short time. But for infrequent work in a home workshop, it is not rational to purchase them.

Hydraulic pipe benders are very powerful and are very good because they do not require physical effort during operation. And if you take into account their low cost, it is clear why they are widely used by construction crews. However, hydraulic pipe benders can be either compact, portable or bulky. The whole difference is what diameter professional pipe they are intended for.

The latter type of machine, for manual bending, is quite possible to make yourself. A self-made tool will cost much less - after all, almost all the necessary materials can be found in any garage. In addition, you can assemble your own pipe bender specifically for the planned tasks, for example, for a certain arc radius.

Homemade designs

Let's list the main structural components and parts from which we can make a pipe bender.

1. For the frame on which the mechanism itself will be fixed, you will need a channel (angle).
2. Rolls of a suitable diameter, which will set the bend of the profile pipe, can be selected or ordered from a turning workshop.
3. You will also need a chain mechanism - gears with a tensioned chain, with the help of which torque will be transmitted to the shafts.
4. Tensioner.
5. An adjustable shaft will require a guide - it can be welded from two corners.
6. A piece of corrugated pipe is suitable as an element that drives the drum.
7. Adjustment screw.
8. Any handle suitable for turning.
9. Bolts for fastening wheels.

The principle of operation of a pipe bender when bending a profile pipe along a radius

How is a manual pipe bender assembled?

A frame of a convenient height for work is welded from a channel, on support legs. On the surface of the base, in the middle, a central roller is fixed. This shaft must be connected to a clamping screw and use it to rise and fall. The central roll is the main element of the pipe bender; it is the one that bends the workpiece.

On both sides of the central shaft, parallel to it, two rotating rollers are installed. The purpose of these secondary rolls is to facilitate bending of the pipe and prevent it from lying parallel to the base, maintaining the bend.

The three rolls should form an isosceles triangle. The limiting rollers can be fixed in one place, or it can be possible to move them relative to the central one. In this case, you can adjust the bending angle of the pipe.

On the working part of the rollers, it is necessary to make guide edges from the corner, which will hold the workpiece in a level position, preventing it from “walking.” Guides will help control the accuracy and uniformity of bending. A drive is connected to one of the rollers.

How is pipe bending done?

A piece of rolled stock that needs to be bent is placed on rollers in a homemade manual machine. Using a screw, the profile is tightly fixed in one position. Then, by rotating the handle, the shafts are rotated, while simultaneously pulling the pipe along them. After turning the pressure screw to increase the pressure, pass the workpiece through the rollers again. In this way, the desired curvature of the arc is gradually achieved. If necessary and persistent, the profile section can even be bent into a ring.

As you can see, there are no difficulties or secrets in making a manual pipe bender for a profile yourself. So there is no need to buy a special machine if you have to do bending a couple of times a year. All that is required is to find the necessary components, and any man can assemble a manual pipe bender. But with the help of such a device you can bend profile blanks into an arc with any radius.

Homemade pipe bender for a profile pipe: device and manufacturing nuances

The need for a reliable and simple device for bending profile pipes arises when a home craftsman begins to seriously work with metal. Gazebo frame, carport, garden bench, workbench

These and many other structures turn out strong and beautiful if the profile metal for them is carefully bent on a special profile bender.

There is always an economical alternative to buying a ready-made machine, since you can make a pipe bender for a profile pipe with your own hands in a home workshop. Before the first workpiece is clamped in a vice, we invite you to get acquainted with the principle of operation and the existing varieties of homemade pipe benders.

How does a pipe bender work?

The operating principle of this device is simple: a profile pipe is placed between three support shafts. The central shaft creates pressure that bends the metal at the desired angle.

A pointing machine is used to bend the pipe in one local area.

Profile pipe bent on a point device

If you need to get an arched profile, then use a rolling bending machine that combines metal bending with broaching.

Types of pipe bending machines

Depending on the drive that transmits force to the profile metal, there are three types of pipe benders:

• mechanical (pressure is created manually using a central screw or lever);
• hydraulic (a hydraulic jack is used);
• electric (bending force is created by an electric motor);
• electrohydraulic (the hydraulic cylinder is driven by an electric motor).

Point mechanical pipe benderMechanical rolling profile bender (the screw creates pressure on the profile, broaching is done using the central shaft and handle)

It should be noted that a rolling pipe bender with manual profile pulling is designed for small cross-section pipes (maximum 40x40 mm). It is impossible to stretch a large profile manually. To bend it, powerful machines with an electric broaching mechanism are used.

Manual rolling bending machine (broaching is performed by the outermost rollers driven by a handle and chain, and the pressure is created by a screw and a central shaft)

about the design of a machine with an electric motor:

How to make a bending machine with your own hands?

The basic principle that should be followed when developing a drawing for a homemade pipe bender is maximum simplicity of design and reliability.

Option 1

A machine for point bending can be assembled from two pieces of channel, four corners and two trimmings of fingers from tractor tracks.

Pipe bending in it is performed by a standard hydraulic jack with a force of at least 5 tons. A steel “shoe” is installed on its working rod. You can order it from a turner or make it yourself from an old pulley, the width of the “stream” of which is equal to the width of the profile pipe. By cutting off a half from the pulley and drilling a seat for the jack rod in it, a hydraulic drive mechanism is obtained.

The frame of the homemade device consists of four corners (60-80 mm shelf) welded to a steel plate. Two channels are welded in parallel to the upper ends of the corners. Holes are drilled symmetrically in their walls to adjust the bend angle of the workpiece.

The manual machine for bending profile pipes is brought into working position very simply:

• Two steel fingers are inserted into the holes on the channel and stop rollers are placed on them.
• The jack with the shoe is raised so that a profile pipe passes between it and the stops.
• Having installed the pipe, use the jack handle to create a bending force.

assembly and operation of a point pipe bender:

Option 2

It is also quite possible to build a rolling manual pipe bender for a profile pipe on your own. To make it, you will need 2 linear meters of channel (wall height 15-20 cm), from which the base and racks are cut.

To make the rollers, take six short pieces of steel pipe. It will act as a cage for bearings. Therefore, its inner diameter must be equal to the outer diameter of the bearing. Having ordered three shafts from the turner for attaching the bending rollers, they begin welding the frame.

For the machine under consideration, the role of a guide setting the angle of bending of the profile is played by the rightmost support. It is mounted on a channel, pivotally connected to the main frame using ordinary door hinges. The jack's working rod rests against the turntable and lifts it.

By rotating the handle mounted on the intermediate stop shaft, the profile is pulled through the machine.

You can adjust the bend radius of the profile not only by tilting the rotary channel, but also by using the outermost rollers. To do this, they are not tightly welded to the frame, but made movable (holes are drilled in the channel and support plates).

Instead of a hydraulic jack, you can use a screw automobile jack to lift the end drum.

How to make a pipe bender for a profile pipe with your own hands

The operating principle of a pipe bender determines its design. These are hand-held, portable and stationary tools, electrically driven, hydraulic. If you need to bend a pipe, the easiest solution is to buy a pipe bender in a store. But you can make a tool with your own hands from scrap materials.

There are several types of pipe benders, which differ in mechanism and principle of operation: hydraulic and pneumatic. Factory units that are driven by both types of drives do a good job of creating bends.

Unfortunately, not everyone can use such devices or purchase a factory version, and mastering bending technology on factory machines without experience is problematic. What kind of pipe benders can you make with your own hands?

What are the common bending techniques?

Manual homemade pipe bender for profile pipes

The homemade profile pipe bender is available in several variations. It all depends on the materials that are available when creating the equipment.

The most common is the frontal one, for the manufacture of which you will need:

• three shafts/rollers – cylindrical in shape made of metal;
• chain;
• axis of rotation;
• drive mechanism;
• metal profiles for the frame.

When creating a machine with your own hands, you make the structure or some elements (rollers) from wood or polyurethane. During operation, it is necessary to calculate the strength of pipes (manufacturing material) that will undergo deformation. Otherwise the structure will not hold up.

Manual bending technology

In the process of bending a profile pipe in a homemade machine, the principle of rolling/rolling is carried out. Pipe bending using this method avoids kinks and damage. The result is an exact correspondence of the desired angle to the degree and size. In the unit, the pipe is inserted between the rollers and bends when the handle is rotated.

Stages of assembling a manual pipe bender

How to assemble a manual pipe bender:

1. Prepare the metal frame for installing the components. The structure is secured by welding and bolted to ensure the strength of the entire equipment.
2. Installation of the rotation axis and shafts, two of which are mounted above the third. Here the bending radius of the pipe depends on the distance at which the two lower cylinders are located from each other. Therefore, to adjust the deformation angle, install the rollers and stopper.
3. The rotating mechanism is driven by a chain. The presence or absence of gears is taken into account here. There are only three of them. A chain from an old car, which is mounted on the shafts, is suitable.
4. Attach a handle to one of the shafts. The element will create a torque force.

instructions. How to make a manual pipe bender

To manufacture a rolling machine for bending profile pipes you will need:

• jack;
• for the frame: metal profiles and shelf;
• 4 high-strength springs;
• 3 shafts;
• chain and other elements.

Roll bending technology

During the bending process in the machine, the pipe is deformed at a given location. The pipe rests on the side rollers, a third one is lowered from above and thus the product is fixed. When the handle rotates, the chain sets the shafts in motion, and the pipe bends at the desired angle.

How to make your own rolling pipe bender

How to make a rolling pipe bender:

1. The pressure shaft consists of gears, rings and bearings secured through a key. Therefore, the main thing in the assembly process is turning the rollers and bearing races. The size of the shafts must correspond to the bearings and sprockets. The turning process is entrusted to the turner based on the drawings. There are three shafts, two of which are located on the sides, and the third is suspended on springs.
2. The next step is to drill holes and cut threads in the rings (for making grooves, threads for clamping bolts) with your own hands.
3. Preparing a shelf from a channel - drill holes and cut threads to install the pressure shaft.
4. The last stage is welding and installation work of the entire structure. First, the frame (legs) is installed.
5. Next, hang the shelf with the pressure shaft on springs and mount the side support shafts, which are connected with a chain. At the end, attach the handle to one of the side support shafts and mount the jack.

Aspects of work:

• the pressure shaft is screwed through keys to the shelf;
• The “suspended” pressure shaft is installed on a shelf. Nuts for the springs are welded to this base. Subsequently, the platform is turned over and attached to springs;
• when tensioning chains, a magnetic corner is used as a holder;
• in the process of screwing the sprockets, install keys prepared from an engraver;
• the rotation handle is made with a rotating tube;
• The jack is mounted on a “suspended” platform using bolts and welding.

How to make a hydraulic pipe bender at home

The hydraulic pipe bender for profile pipes is equipped with a hydraulic cylinder, bars, a pressure device and pipe stops. Making such a unit at home is a labor-intensive process.

https://www.youtube.com/watch?v=FavBjUEEpPk

Equipment details:

• hydraulic jack (not less than 5 tons);
• shoe;
• several rollers (2-3);
• channel;
• metal plates and other parts.

Hydraulic bending technology

The bending process involves deforming a given section of pipe using a hydraulically driven jack. The pipe is inserted into the shoe and both ends are secured. Engage the jack by turning the handle slowly. The force created by the hydraulic drive is transmitted to the roller - the pipe is bent at the desired angle. The work can be stopped at any time; the pipe can be pulled out by making a couple of turns of the handle in the opposite direction, that is, releasing the pressure of the roller.

How to make a hydraulic bending machine

We make a hydraulic bending machine with our own hands:

1. A channel structure is pre-prepared where the shoe and rollers will be located. Then the frame of the machine is made of similar metal.
2. The last platform of the structure is reinforced with metal plates. Subsequently, a jack will be mounted on this shelf. Secure the device with bolts and attach the handle.
3. The difficulty is finding or making rollers that should wrap around the pipe. The parts are mounted in a rectangular channel at an equal height. The shoe is installed lower. The arrangement of the parts determines the specified bend radius.
4. The rollers and shoe are secured with bolts. The holes are prepared in advance.

instructions. How to make a hydraulic pipe bender

When bending pipes, it is necessary to know the diameter of the material and the principles of the process. This will ensure correct deformation of the material without overload or kinks. On machines using hydraulics, it is possible to bend a section of pipe with heating, which allows you to bend products with large wall thicknesses, made of durable alloys and polymer materials.

Hot and cold pipe bending methods

Pipe deformation is carried out in two ways:

Cold bending is used for pipes made of plastic material. As a rule, these are small-sized products made of copper, aluminum and other materials (except cast iron), metal-plastic. The process is carried out using machines or a mechanical pipe bender. For better bending, sand, salt, or oil and water (ice) are poured into the pipe before deformation.

Tatyana Pronina, expert

The second method is used to deform pipes with increased ring rigidity (stainless steel, etc.). The method can be used for all types of pipes, except metal-plastic.

How to make a template for bending pipes along a radius

The simplest method is to bend the pipe according to a template. The principle is to deform the material by applying it to a wooden structure with a radius of curvature. The method is suitable for aluminum and steel pipes with small wall thickness.

The template is cut out of wooden boards, which are fastened together with bolts or in another most convenient way. The entire structure is bolted to a table or other stable base.

The thickness of the template, where the pipe is directly applied, is several centimeters greater than the diameter of the pipe being bent. The end of this part (the edge of the template) is cut at an angle so that the pipe does not slide off the ledge.

An emphasis is mounted on the template. A pipe is inserted between it and the base of the template and gently pressed - the material bends.

Useful tips from the experts

1. If you are assembling a manual rolling pipe bender for profile materials, then you can not use sprockets, but build a structure with a drive on one roller. But the mechanism will periodically slip. The clamping screw can be replaced with a jack.
2. When making the template, use hooks attached to the wood to prevent the pipe from slipping.
3. If you have to bend a pipe under a large radius, it is better to make a unit with three rollers.
4. The greater the distance between the rollers, the less force is applied for bending.

   To change the bending radius, first provide for the possibility of the rollers moving horizontally relative to each other.

Buy in a store or make it yourself

Profile pipe bender "Hercules"

The machine that you can buy in a store may have a different type of drive and a different principle of operation, but this is not always good. Firstly, to work on it you need some experience, and secondly, such devices are expensive. For these reasons, making a homemade pipe bender from scrap materials is not only profitable, but also practical, since when assembling the tool you will know the slightest nuances of its operation.

Why do you need a pipe bender?

Main elements of the machine

Today, profile pipes of different cross sections are the most popular metal products.

They are used to make frames and lathing, fences and railings, with their help they expand balconies and even build various architectural structures in the form of extensions or separate rooms.

But sharp turns are not always used in construction - sometimes a smooth transition is needed, and in these cases you can’t do without a pipe bender. As a rule, such a machine allows you to bend a profile to an angle of 180⁰, that is, the device allows you to make a circle.

Main design elements

Principle of operation

To manufacture a particular machine design, you should look through several diagrams to determine the set of parts. The fact is that, if necessary, all the components of the units can be purchased for money, but you can also use the materials that you have on your farm and not pay anything for it. In most cases, home craftsmen opt for frontal structures, and for this you must have:

• three metal rollers (rollers);
• drive chain;
• axes of rotation;
• drive mechanism;
• metal profiles (channels) for the frame.

Sometimes, in the absence of metal rollers, they are replaced with wooden or polyurethane ones, but such a rolling mechanism will not withstand long-term load, that is, the machine will serve its purpose, but not for long. Is there any point in wasting your labor for short-term benefit if, with some effort or even paying a certain amount, you can find steel rollers?

Diagram of a simple pipe bender with dimensions in mm

As you understand, the process of profile deformation occurs using rolling, that is, the pipe is rolled over rollers (rollers), which eliminates breaking and cracking.

To roll (bend) a profile, it is inserted into the rolling line (between the rollers) and pressed from above with a screw device or a jack to the desired bending radius. Then, when the feed handle is rotated, the pipe moves and the bend runs along its entire length.

It turns out that this is a manual drive, which is driven by muscular force, but at home such a mechanism is very convenient.

The profile is pressed using a jack

To assemble the simple pipe bender in question with your own hands, you will need:

• jack (preferably rack and pinion type);
• metal profiles with a shelf for horizontal and vertical frames;
• springs made of alloy steel (they are distinguished by high strength);
• three steel shafts with bearings;
• drive chain (can be from a bicycle or moped);
• gears (driver and driven);
• Thick reinforcement for axles and drive handle.

pipe bending process

As you can see, it is easier to make a profile bending machine with your own hands using the existing drawings, and photo and video materials only help with this. The profile bender shown in the picture is driven by a handle that rotates the shaft with the drive gear. Using a chain, rotation is transmitted to the shaft with the driven gear, and the third shaft presses the profile from above to the required bending angle. Everything is very simple.

Mechanism manufacturing process

Bending device drawings

If you are interested in how to make a profile bender, then you will have to perform a number of actions that will ensure this reliability of the mechanism, and this is:

• production of a powerful frame assembled using welding and bolt ties;
• according to the terms of the drawing (technical specifications), make and install rotation axes for the rollers. There are three of them - two rolling and one clamping;
• To rotate the rolling rollers, you need to provide a chain transmission, that is, weld (evenly) the drive and driven gears;
• Weld a handle for rotation onto the drive gear.

Manufacturing nuances

Ready pipe bender

If you have all the necessary parts available, then making a mechanism for bending the profile is not difficult. First of all, you need to take into account that all rollers must rotate on bearings - the accuracy of rotation will ensure correct rolling, without failures or breaks. The drive and driven gears must be correctly centered - a deviation from the center by at least 0.5 mm will lead to incorrect deformation (the bend will be uneven).

The pressure shaft must also be centered - the accuracy of the bending angle depends on this. It is best when the dimensions of all three shafts are the same - the rental results in the clearest. The rolling accuracy also depends on the rigidity of the clamp, so the shaft must be well fixed.

Hydraulic pipe bender

Hydraulic drive mechanism

To make a hydraulic pipe bender for a profile pipe with your own hands according to ready-made dimensions and drawings, you will have to spend a lot more labor and resources. However, it can be done and we will now look at the procedure. For assembly you will need:

• hydraulic jack with a lifting capacity of 5 tons;
• shoe;
• three shafts;
• channel for frame;
• metal plates (thick).

hydraulic driven mechanism

To correctly bend the profile, it is inserted into the shoe and both ends are secured. After this, the jack is activated - it presses on the pressure shaft and sets the desired bending angle. After rolling, the jack is loosened several turns and the pipe is removed from the device.

Drawing with dimensions in mm

The jack is attached to a metal plate using bolted connections. But in such a mechanism, the most important thing is the shafts, which must tightly grip the profile - the accuracy of bending depends on this. The shafts are fixed at the same height and gears are welded to them. The shoe is attached below the shafts, and the ratio of the shoe to the shafts determines the bending angle. Fixation occurs using bolts.

Bending Methods

Cold profile bending

If you have read all the descriptions, looked at the photos and videos, then the bending process itself is unlikely to confuse you.

If you decide to make a hydraulic device, then you can bend pipes of any thickness on it - the most important thing is that the shafts (rollers) can withstand it. But I would like to mention one nuance - arching can be not only cold, but also hot.

Heating usually occurs using gas welding, this is very convenient, especially since you can heat only part of the pipe, that is, the section that needs to be bent.

We can say that the cold bending method is the simplest and if you are working with a thin-walled pipe, then you do not need to heat it at all. But there can also be problems here - this is the seam.

Profiles are not always made with high quality and a bad seam simply comes apart when bent. This can be avoided by heating, but not always. A low-quality pipe will remain that way and no amount of heating will help.

However, if you use a profile for the frame, then a small crack along the seam will not become critical.

Do-it-yourself pipe bender for a profile pipe

Bending a metal profile is a common operation in both private and industrial construction. The need for it arises during the construction of frame buildings, greenhouses and sheds. Special equipment allows you to give a profile pipe the required shape - a pipe bender, which we will talk about in this article.

Homemade pipe bender

The publication discusses the device, the operating principle of such equipment and provides instructions, following which you can make a pipe bender for a profile pipe with your own hands.

Pipe bender design and required materials

In construction practice, at different times, many different models of bending machines were used, differing from each other both in their structural design and operating principle. However, roller pipe benders have proven themselves best; in comparison with their analogues, they are more efficient and easy to operate.

The design of such a machine consists of the following elements:

• 3 rollers - two of which are fixed, and the position of the third can be adjusted vertically, thereby changing the bending radius of the pipe;
• the axis of rotation on which the rollers are mounted;
• a drive mechanism consisting of gears connecting their chains and a hand lever;
• supporting frame on which all the above elements are fixed.

Note that a pipe bender for a profile pipe must be equipped with steel rollers. Wooden and polymer rollers are suitable for working with plastic pipes; for a metal profile, their strength characteristics will not be enough.

Pipe bender diagram with dimensions

Such pipe benders work on the rolling principle - this is the most gentle bending method, which reduces the likelihood of profile fracture to zero. To bend the pipe, it is necessary to lay it on two lower rollers and lower the upper one so as to create pressure on it, after which the rollers are rotated using a hand lever and bending begins. The process is repeated until the structure is given the required radius or bending angle.

To make such a pipe bender with your own hands you will need the following components:

• standard car jack;
• 3 steel rollers;
• square profile for frame;
• springs;
• chain and handle for drive;
• bushings, metal plate or channel to support the machine.

To make a frame, you need to take a 20*20 profile with a wall thickness of at least 5 mm.
The diameter of the rollers is selected according to the width of their internal groove; you must be guided by the maximum size of the pipes you plan to work with. to menu

How to make a pipe bender - step-by-step instructions

To make a pipe bender with your own hands, you will need power tools such as a grinder (with a cutting and grinding wheel), a welding machine and a screwdriver. We recommend pre-coating all metal elements of the machine with an anti-corrosion primer, this way you will significantly increase its service life.

Homemade pipe bender for profile pipe

The dimensions of the machine are shown in the above diagram; its assembly is carried out according to the following algorithm:

1. A piece of channel is cut to a suitable length, which will be used as a support plate for the frame.
2. Next, the cages for the bearings inside the rollers are turned on a lathe and two sections of an angle 10-15 cm high are welded vertically to the support.
3. The main supporting platform is mounted under the rollers from a similar channel, the length of which is 10 cm shorter than the length of the bottom plate.
4. A through hole is drilled in the extreme part of the upper channel, in which a piece of the upper channel of the missing length is mounted on a threaded bushing. A jack is installed under the section, which rests the lift against an adjustable plate.
5. 3 rollers are welded to the top of the frame, which are installed in bearings. An angle is used to raise the side rollers above the surface of the plate; the central one is raised to a greater height by means of a rectangular profile.
6. An axis of rotation is installed in the hole of the central roller, to which the drive handle is welded, after which the shaft is connected by a chain to the remaining rollers. It is not recommended to make a homemade pipe bender without a chain, leaving only one drive roller, since in this case the operating efficiency may decrease due to the profile slipping during rolling. It is best to make a rotating handle on the drive lever.

   Bending process

Making a good pipe bender with your own hands is not enough; you also need to learn how to work with such equipment correctly. There are two bending methods - cold and hot. The cold method is the easiest to implement, but at the same time a very crude method, since it leaves a visible deformation on the profile in the place where the roller was pressed into the pipe at the beginning of the process (the rest of the profile bends evenly).

data-ad-client=»ca-pub-8514915293567855″
data-ad-slot=»5929285318″>

However, using the cold method when working with particularly thick-walled profiles is quite problematic, since it requires significant labor costs.
Hot bending is optimal here, which involves heating a section of the pipe in the initial impact zone, which can significantly increase its plasticity. It is best to use a blowtorch as a fire source. to menu

How to bend a pipe without a pipe bender?

If for some reason you do not have the opportunity to make a full-fledged pipe bender with your own hands, you can design a template for working with pipes. This is a good option for bending aluminum and copper pipes, but processing a steel profile on a template is quite difficult.

Bending on a wooden template

There are several types of templates, the simplest of which is a wooden structure. From solid wood whose thickness exceeds the diameter of the pipe being processed, it is necessary to cut a semicircle (the dimensions are selected in accordance with the required bending radius). The resulting semicircle is fixed on a workbench or other stable surface, and a stop is mounted on the right side of it, which will fix the profile being processed.

At this point, the simplest homemade pipe bender can be considered ready. For bending, it is necessary to place the profile in the hole between the template and the stop, and then apply pressure on its free end to give the pipe the desired shape.

Metal hook pattern

To work with polymer pipes, a similar template can be made from metal hooks, rigidly fixed in the shape of a semicircle on a wooden surface.
However, a metal profile will not withstand such a design. to menu

Shop machines

Having learned how to bend a pipe without a pipe bender, you can understand that the task is complex and dreary. Therefore, if you do not have the skills to make a homemade device, a rational solution would be to purchase a factory-made bending machine.

For simple tasks, Instan pipe benders are the best option. The company’s product range includes about 10 different models, but the hydraulic pipe benders of the TPG series have proven themselves best, namely:

• Instan TPG-1B;
• Instan TPG-1.25B;
• Instan TPG-2B.

Instan TPG-1

The numerical designation in the marking indicates the maximum diameter of pipes that this machine can bend. The TPG series machines use a direct-acting hydraulic cylinder as a power element, which is driven by a pumping device. Bending templates are supplied with the machines, allowing you to process pipes with a minimum diameter of 3/8″.

As an alternative to Instan machines, you can consider ZUBR pipe benders. We recommend paying attention to the ZUBR-12 model, the cost of which is 13 thousand rubles. Let's look at its technical characteristics:

• maximum force - up to 12 tons;
• maximum bending diameter - 51 mm;
• working sections - circle, square;
• rod stroke - up to 230 mm;
• bending angle - up to 90 mm.

Pipe bender ZUBR-12

ZUBR-12 is a fairly large bending machine, the weight of which exceeds 35 kg. The unit comes with 2 replacement rollers and 6 attachments for working with pipes of different diameters. For processing thick-walled profiles, the ZUBR-10 model is better suited, which allows you to bend products with walls up to 5 mm thick and a cross-section up to 76 mm.

For household use, there is no particular point in purchasing an electric pipe bender, unless you are engaged in small-scale production of metal structures. First of all, such a purchase is irrational due to the high cost; prices for proven models start at 100 thousand rubles. However, if necessary, we recommend paying attention to electric bending machines Stalex HTB-1000 and ENN-40.

DIY pipe bender for profile pipe + drawings

Profile pipe is rightly considered one of the most popular materials in the household. Up to 90% of the frames and load-bearing structures of homemade garages, outbuildings, and all kinds of tools and devices are made from pipes. Often, in order to achieve the necessary curvature of a profile pipe, for example, to build an arched roof, you need a pipe bender that can work with both regular and profiled pipes.

Therefore, both manual and lever-roller pipe benders are used for individual production of all kinds of parts and adapters, for example, when repairing water supply systems and simple building structures. The rolling-roller design of the pipe bender allows you to bend relatively simple products from a profiled pipe, but in an unlimited number of times.

The manual method of bending a heated profile pipe on a calibrated blank has been used since time immemorial and gives good results. It is best to bend a regular pipe; for a profiled one, you will need to double the number of bending transitions so that the formation of ruffles or waves does not occur on the edges. Before heating, the pipe is filled with clean and dry calcined sand. The ends are welded or pressed with metal plugs.

The device of a rolling pipe bender differs from previous versions in that before bending a profiled pipe, the required radius of curvature is set, after which the pipe blank is quickly rolled into a curved profile using a chain drive and a pair of rollers.

The easiest way is to assemble a pipe bender with your own hands, the drawings of which are given below.

The design of a rolling roller pipe bender consists of several basic units:

A massive frame welded from channel steel. Structurally, the pipe bender frame consists of two posts welded to a massive base plate. A jack is attached to the racks, with the help of which the necessary force is created to deform the metal;

Roller drive system. After pressing the profiled pipe with a jack to the roller surface, the metal of the pipe is deformed with simultaneous rolling of the profiled material;

The chain drive system is used to pull the profiled pipe through the deformation bar of the pipe bender.

The operating principle and bending speed can be further clarified from the video:

Assembling the frame and drive mechanism of the pipe bender

Initially, the pipe bender frame is assembled. To do this, two vertical posts are welded into a U-shaped vertical structure.

Next, a screw-nut pair from a jack with a lifting force of at least five tons is welded onto the manufactured support. Particular attention must be paid to the precise installation of the screw nut so that when screwed in, the screw descends strictly in the vertical direction.

At the next stage, two roller bearings are welded, mounted on a 30 mm cast axle. A bicycle sprocket is attached to the axle on the side by welding. Thus, a chain transmission is obtained. In order for the machine drive to work without slipping, you will need to change the length of the chain to match the actual distance between the sprockets.

Pipe bender operation sequence:

• A profiled pipe is placed on the rollers and pressed with a screw; after the first rolling, the position of the screw is measured and the bending radius is measured;
• To obtain the required curvature of the profiled material, use a vertical screw to proportionally change the amount of deformation;
• The most massive profiled pipes are rolled in several passes.

The bending accuracy of a profiled pipe can be easily assessed from a photograph. Bending a profile is a rather difficult and labor-intensive undertaking, therefore, if the pipe bender is planned to be used on an ongoing basis, it makes sense to equip the machine with an electric motor with a gearbox.

For workpieces with a cross-section of more than 30 millimeters, instead of bicycle chains and sprockets, spare parts from the timing drive of Volgov and Moskvich engines are used.

Roller-lever version of the pipe bender

A simpler and easier to manufacture design of a pipe bender is shown in the drawing and photo.

The design is based on a pair of bending roller and base plate. The head roller is driven using a two-meter lever, which makes it possible to obtain a huge force on the bending tool, approximately one and a half tons. The roller itself is a twenty-centimeter circle with centering sides. The width between the sides is equal to the cross-section of the profiled pipe.

Important! The tool has to be adjusted to the parameters of the corrugated pipe by replacing the main roller with a tool with the appropriate width of the bending part.

The process of bending a profiled pipe occurs in stages. The workpiece is marked into several sectors. The profile is placed into the machine and fixed using clamps according to the previously made markings.

By simply turning at a given angle, the corrugated pipe bends along a given radius. Next, you need to rearrange the next sector and turn the lever exactly to the specified angle. The stability of the bending radius depends on how accurately the sector of the profiled pipe is positioned in the machine clamp.

The most successful designs of pipe benders

To achieve high productivity, when bending corrugated pipes they often use not two rollers, but three, and a hydraulic drive is used instead of a screw jack. In this case, you can bend a profiled pipe with a cross-section of up to 50 mm.

Three-roller pipe benders allow you to obtain not only flat, but also helical spiral shapes. Of course, the deforming force increases several times, so the pipe bender drive is equipped with a gearbox.

It is much more difficult to bend a quadrangular profile towards the smaller side of a rectangular section. In this case, the pipe bender must be used in at least four passes. If a welded profile is used, it is recommended to heat it to 200°C before rolling.

How to make a pipe bender for a profile pipe with your own hands

When installing most metal structures, bending pipes at different angles is required. A ready-made device for this can be bought at hardware stores, but what if it is unlikely to be useful anymore? Is it worth spending money on a mechanism if it will later gather dust on a workshop shelf? The simplest and most logical solution is to build the device yourself. How to make a pipe bender for a profile pipe? Recommendations from experienced craftsmen and video instructions in this article.

A self-made device will help you give the product any shape.

How does a pipe bender work?

Rolled metal, bent at a certain angle, is necessary in many structures. Among them:

• engineering communications in residential buildings: water supply, sewerage, ventilation;
• fencing around the perimeter of the site;
• home and garden furniture;
• greenhouses;
• gazebos and canopies.

Complex metal structures require the use of benders or a pipe bender

You can bend any rolled metal, the main thing is to use the right tool for this purpose. Not only steel structures can be given the required shape; metal-plastic, copper, and aluminum can be bent.

Helpful information! To select a pipe bender, you need to take into account not only the cross-section of the product, but also its profile. Simple round pipes can be bent much easier than profile ones. If handled incorrectly, the latter can become significantly deformed or even break.

To use the tool correctly, you need to carefully study the advice of professionals in the video. A do-it-yourself pipe bender for a profile pipe can be made in a simple, manual version or using hydraulics.

It is believed that the profile material is more difficult to bend

Hydraulic devices quickly and efficiently bend any metal parts.

A conventional front pipe bender consists of the following elements:

• three metal shafts;
• drive chains;
• rotating axis;
• rotating mechanism;
• frames made of metal profile.

Handheld device diagram

Sometimes the shafts are made of wood or plastic, but it is worth taking into account that such rollers will not cope with any pipe. If you do not calculate the resistance of the material, the shafts may simply collapse.

How does the profile bending device work?

Before you start making a homemade pipe bender for a round pipe or profile, you need to understand the principle of operation of the device. The action of the mechanism is based on rolling or rolling. This principle helps eliminate the risk of accidentally deforming and breaking the material. To give the metal the desired shape, it is inserted between the shafts and the handle of the device is turned. The result should be the desired bend.

By changing the rollers, you can achieve different bends

Do-it-yourself pipe bender for a profile pipe: types of devices

The devices differ in purpose. There are devices for forming turns on steel, metal-plastic, copper, and aluminum products.

Devices can be portable or stationary. Portable models are convenient because they can be installed directly in the room where communications are being installed. Stationary machines are used in production.

Stationary industrial pipe bender

Note! Improper use of the machine can lead to changes in the internal diameter of the pipes, wrinkles of the surface and changes in wall thickness.

Manual pipe bender

Soft materials, metal-plastic and copper, are easily bent with a hand-held device. Its design is quite primitive. The bender itself does not take up much space and can easily fit in a small workshop. In addition to the pipes themselves, you can bend reinforcement or rolled metal on it.

A simple hand-held bending device

Hydraulic device

This device is capable of giving the desired shape to material with diameters up to four inches. The profile material, using hydraulics, can make intricate bends, repeating the topography of the wall.

Helpful information! Metal parts of the structure must be thoroughly lubricated to protect against rust. You can even provide a special compartment for automatic lubricant supply.

Model No. 1 – rolling

Assembly algorithm:

• The metal base must be secured to a flat, durable surface and holes must be drilled at the ends.
• The steel rectangular plates must also be drilled to secure the rollers.
• Secure the plates to the base with nuts and bolts.
• Install rollers of the required size into the grooves and secure them firmly.
• In the center of the base, weld the stands for the central shaft and secure it with a stud and nut.
• Provide one shaft with a handle for turning.

Result: You should get a design like in the photo. You can not use a metal base, but attach the plates directly to the base.

Rental model

Model No. 2

Another pipe bender for a profile pipe with your own hands, of a simpler design, will cope with products with a cross-section of two and a half centimeters.

Work order:

• It is necessary to make a device template on paper.
• From scraps of lumber, assemble the device according to the template, fastening the parts with self-tapping screws.
• Screw the resulting module to the wall. Screw a beam onto one side of the module for support.

Advice! When screwing parts, you need to focus on the diameter of the pipe. It should be easy to insert and lock into place.

Result in the photo:

Sample model

Model No. 3

This version of a do-it-yourself pipe bender for a profile pipe is even simpler:

• A sheet of plywood is screwed to the wall, and the desired bend is depicted on it.
• Metal hooks are secured along the line with screws. Metal plates must be attached to each hook; they will additionally secure the material being bent.
• It is necessary to provide a stop for the end of the pipe.

Advice! If you don’t have enough strength to manually perform the desired bend, you can use a winch.

Result:

Plywood pipe bender

Application of hydraulics

For a hydraulic device you will need:

• rollers – 2 pieces;
• hydraulic jack;
• shoe;
• channel;
• steel plates.

The jack is fixed on the workbench. It will push the pipe into tight gripping rollers. If you prepare rollers of different diameters, you can work with products of any size.

Such a device does not require additional costs, and every motorist has a jack

do-it-yourself manual pipe bender for a profile pipe

To construct a pipe bending device, you can use ready-made drawings. “How to make a pipe bender for a profile pipe with your own hands” will reflect the manufacturing procedure and the method of using the resulting tool.

Recommendations from professionals

• To bend, rolled metal must be heated, especially on the outside of the diameter.

You can heat the pipe with a gas burner

• To prevent deformation, the pipe must be filled with sand before bending.

Sand will prevent the pipe from breaking

• If you are not sure of the result, don’t try it. Sometimes it is easier to buy ready-made bends and weld them to the pipe than to correctly give it the desired shape.

It is quite possible to make a simple device for bending rolled metal with your own hands. If you need to make a metal structure with a complex configuration, it is better to use the rolling method. For a couple of simple bends, a device using hooks is suitable.

Using a pipe bender you can get any shape

It is worth remembering that the wrong ratio of force and excessive haste can lead to irreparable deformation of the material.

Types of pipe benders for profile pipes, do-it-yourself manufacturing schemes

:

A pipe bender for a profile pipe is a tool needed for certain situations, and there is a steady demand for it in the market. The pipe bender can be used in a variety of areas where there is a need to give a pipe a specific shape. Of course, such a tool can be purchased, but if you want to save money, you can make it yourself.

To assemble a pipe bender, you need knowledge about its structure, operating principle and characteristic features. This work will also require the appropriate tools and instructions. How to make a pipe bender for a professional pipe with your own hands will be discussed in this article.

Main characteristics of a pipe bender

Structurally, a profile pipe bender is a specific machine for rolling profile pipes, which allows bending pipes with various profile cross-sections.

Good pipe benders for profile pipes allow you to solve several problems, including:

• The ability to bend the pipe at the required angle, the value of which can reach 180 degrees;
• Ability to work with pipes in a fairly wide range of diameters - from 5 to 1220 mm;
• Possibility of processing pipes made of different materials (if necessary, you can bend both metal and plastic products).

In principle, there is no need for a pipe bender for processing polymer pipes - such material can be bent in other ways. But when processing metal products you cannot do without professional equipment.

Of course, you can always purchase a ready-made tool or rent it, but these solutions cannot be called the best. Renting specialized equipment is usually expensive, and purchasing it is even more expensive. In addition, you need to understand that buying a pipe bender for a one-time job will not be the most profitable option. To avoid unnecessary costs, many people make pipe bending machines with their own hands.
