How to make your own pipe bender from a jack

Homemade pipe bender, how to make it at home

It is necessary to bend long straight workpieces in a variety of cases. Without going into details, the process can be divided into several areas:

1. Bending of thin-walled pipes. It is used in the manufacture of lightweight building forms - canopies, gazebos, as well as frames for domed roofs or greenhouses;
2. Bending thick-walled and generally durable pipes. It is used for plumbing work, the manufacture of water heating devices (coils, batteries) and car tuning;
3. Giving complex shapes to round and square steel rods. Used in the manufacture of shaped grilles, fences and gates;
4. Square profile bend. A more complex technique than with pipes and rods.

We will not discuss the purchase of an industrially manufactured device; there are specialized marketing services for this. This article discusses how to make a pipe bender at home.

The simplest ways to bend a pipe or circle (rod, fittings)

It is not at all necessary to create a complex device with mechanics, levers and rods.
This does not mean that you can bend pipes “on the knee”, although many people do this. There are elementary devices that are usually made one-time for a specific task: for example, stretching polyethylene over a greenhouse. For bending pipes or metal rods (circles) of small diameter, it would be most reasonable to make a template.

Wooden guides are installed on a flat surface, cut to match the radius of the intended bend. The material for the device is literally lying under your feet. A retainer block is nailed on one side, the workpiece is placed on the surface and, with the help of muscular force, bends around the template.

The primitiveness of the design does not at all reduce its effectiveness. In just an hour you can make equipment for one or two film greenhouses.

If the workpiece is too rigid and it is impossible to bend it with your hands, use small mechanization. The pipe is secured to the template with clamps, and its end is grabbed by a winch. The effort increases many times, but the principle of operation of the device remains the same.

Another version of a template pipe bender with an unlimited choice of the shape of the workpiece can be built from hooks. We take a sheet of plywood or OSB board, mark the required curve, and attach the hooks in increments of 10-15 cm. The beginning of the pipe is traditionally secured with a wooden block.

If you regularly have to change the radius of curvature, attach the hooks to self-tapping screws. When making a permanent template, use screws and nuts.

Muscular force is still used to bend. It is somewhat more difficult to make such a machine, but this disadvantage is more than compensated for by functionality. You will have access to radii from 10 cm to several meters.

Lever pipe bender

The design consists of two levers connected by a hinge. Design features - no frame or workbench is required for operation. Bending the pipe occurs with both hands, right in the field.

This device is suitable for durable workpieces of small diameter. In fact, the performance of the device is limited only by the effort of the operator’s hands.

You can make a lever pipe bender yourself, but this will require welding and plumbing equipment.

Homemade pipe bender from a jack

The design is quite complex to manufacture, but the capabilities (power) exceed all expectations. Using electric welding, a durable frame is made; the device can be made multifunctional - a pipe bender and a hydraulic press in one set.

You can choose any jack, from 5 to 12 tons. It is advisable that this be an independent tool; it does not have to be constantly disassembled to place the jack in the trunk of your car. With such loads, the hydraulics must be securely fastened to the frame, and disassembling the mount each time after completion of work will be tedious. At car dismantling yards, or car depots of defunct enterprises, you can choose a suitable option.

It is necessary to make a punch from a pre-bent pipe or an old pulley (for example from a crane). Depending on the tasks assigned, there may be several of them, depending on the diameter of the workpieces.

The pipe rests on rollers mounted on an axle along the edges of the frame. The jack, using a shoe (punch), presses on the center of the workpiece, causing a smooth bend. To understand the operation, here is an example of an industrial pipe bender with a similar operating principle:

DIY hydraulic pipe bender

Pipe benders are often used by plumbers and builders. It is also quite difficult to create any non-standard metal structures without them, especially if we want to work using cutting and welding to a minimum.

It is thanks to the presence of pipe benders that the process of assembling domestic pipelines has become so simple and fast.

After all, you no longer need to cut the pipes each time and then fasten them with fittings. You can do it much simpler - by bending the segment to the desired degree. This way you will save your time and resources.

Pipe bender made from slats and jacks

But a construction pipe bender is not a cheap tool. Not everyone can afford it. Therefore, we will now tell you how to create a homemade analogue.

Design and principle of operation

Before you start assembling your own tool, you need to understand how a pipe bender generally works. In fact, there is nothing complicated here. It operates on the principle of isolated deformation.

Let's just say that if you are going to bend a pipe without fixing it properly, then the bend radius will be very large. In fact, you will simply end up with a wide arc, which is clearly not what you wanted.

By pre-fixing the segment in several places, the rotation angle will become as you wish. It all depends on the position of the clamps themselves. The smaller the distance between them, the smaller the bend radius will be.

Actually, a pipe bender works on the same principle. This is just a working tool with conveniently mounted pipe mounts.

You push the pipe into the cavity of the pipe bender, then adjust the fasteners to the desired distance. There is a nozzle between the fasteners. It is directly affected by the engine. It can be either a round disk with several convex arcs (works by rotation), or a cast steel part in the shape of a crescent.

Example of a horizontal pipe bender design

In the first case, the pipe bender will work by winding the raw material onto its nozzle, while in the second, the rod is acted upon in the opposite direction from the fasteners, thus bending the pipe to the desired radius.

It should be understood that the fasteners in pipe benders are not rigid. They allow the pipe to move slightly, but at the same time hold it well on the machine.

That's all the magic. As you can see, nothing complicated. One way or another, forces are simply applied to the pipe in the right place and in accordance with the standard stresses. The result is an effective way to cope with the task.

Types and differences

The design of a pipe bender is in many cases the same, only the methods of applying force differ. In this regard, they are divided into:

• electrical;
• hydraulic;
• manual.

An electric pipe bender is an expensive, powerful tool that operates using an electric drive. This can be either a manual mobile sample or a large stationary machine capable of bending hardened steel pipes with a diameter of 80 mm or more.

The hydraulic pattern involves the application of hydraulic pressure principles.

Well, a manual pipe bender is a primitive product that simply improves the shoulder for applying force, thus making it easier for a person to work. You already need to work hard with it, but if there are no other options, this one will do.

We will turn our attention specifically to hydraulic tools. The fact is that a homemade pipe bender is easiest to make from a jack. It will combine high efficiency, power and ease of operation.

With simple manual models there is too much hassle and low output efficiency, and electric ones simply cannot be imitated with your own hands at home. Not everyone can afford to buy them in a store. And rarely does anyone need this.

Why a jack?

The circuit of our homemade pipe bender is based on a jack. The use of a jack is due to several of its advantages:

1. Availability.
2. Efficiency.
3. Cheap.
4. Openness to the introduction of modifications.
5. Mobility.

Pipe bender from a jack, disassembled

A jack is mostly a hydraulic tool, or a mechanical one, it depends on the model. In any case, it allows a person to work on the principle of accumulating physical effort.

It is quite efficient and has good power. If a jack is capable of lifting a car weighing several tons, then it will somehow cope with a steel pipe of medium diameter.

Jacks are also cheap, they are sold almost everywhere and are available. What can I say? A used model can be exchanged at any auto repair shop for almost nothing.

Well, let’s not forget that when working with our own hands, we are interested in the dimensions of the tool and the possibility of simple interaction. Everything is fine here too. A standard jack is easy to move with your own hands. It weighs around 10 kg and is easy to disassemble and modify. Assembled from the simplest, but at the same time extremely reliable parts.

Device diagram

Our self-assembled pipe bender will consist of several parts fastened together into a single structure.

To be more precise, the scheme involves:

1. Mount or base.
2. Frame for holders.
3. Rollers with clamps.
4. Jack with attachment.
5. Additional details.

A steel plate or concrete block is used as fastening. Here you need to think through the design of the assembled equipment in advance.

If you want a stationary sample, it is better to take a heavy steel plate, drill several holes in it and then use it as a base. This will be something like a machine bed.

A manual pipe bender uses its own body as a basis. Unfortunately, it is very difficult to assemble a truly effective manual pipe bender with your own hands, so we are not considering this option.

The frame for the holders is assembled from any suitable parts. From profile pipes, welded in the form of a rectangle with stands, to channels.

The frame must have two supports; roller clamps are mounted on the supports on top. There must be space between the supports.

The rollers are taken from ordinary ones, from old machines, carts, etc. Whatever is on hand can be used. The purpose of the roller is to fix the pipe, but to fix it softly, with the ability to shift the position a short distance. The rollers are mounted on rods that are screwed into the frame.

Large attachment for a homemade pipe bender

A jack is mounted in the center of the structure, just between the bases of the frame. We'll talk about its installation a little later. The attachment is mounted directly on the jack press. You can sharpen the nozzle yourself. Or you can buy it on the used equipment market.

Well, as additional parts you can use a lot of interesting add-ons that will allow you to simplify the bending process with your own hands, add the ability to modify the equipment, change it or improve it.

For example, these could be additional fasteners for bending pipes in several places, various kinds of clamps, angle meters, etc.

Build process

Let's figure out the order in which to assemble a homemade pipe bender from a jack. This process is quite simple, but at the same time it contains several nuances and secrets.

Stages of work:

1. We prepare the base, drill holes in it for attaching the frame.
2. We weld the frame and attach the holders to it.
3. We mount the frame on the base. It is advisable to use bolted connections rather than welding.
4. We make several holes in the jack frame for fixing.
5. We mount the jack under the frame.
6. We put on the nozzle.
7. We install additional parts.
8. We check the strength of the connections and test the functionality of the tool.

So, the homemade pipe bender is ready. As you can see, there is nothing really complicated here. The device stands on a steel plate, a steel frame and a jack are screwed to it.

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

The recommendation to use bolted connections is indicated for a reason. As you interact with your craft, you will probably understand how it can be improved or remade.

As a rule, the modification process is accompanied by complete disassembly of the pipe bender. And if you welded the parts to each other, then disassembling them will be much more difficult.

The use of welding is permissible when assembling the frame from individual parts. That is, profile pipes can still be welded together, but the frame and base are no longer desirable.

A crescent-shaped nozzle is mounted on the jack, with its convex part facing the pipe. Under pressure, the nozzle will constantly act on the pipe, causing a smooth bend in the desired direction.

Final tips

The diagram we have given is just one of the options. There are other solutions that can also be used. Try to choose the one that suits you best.

For example, in some home-made models, people do not use full-fledged metal bases made of plates, and in place of the bottom they simply weld several additional profile pipes at the bottom of the frame.

The fastenings can also be modified. If you don't have steel rollers available, you may be able to find short pieces of high-pressure pipe. These 10-15 cm long scraps are sawn along the central axis, creating a kind of semicircles.

They are then welded onto metal rods and mounted into a frame. Jacks can also be selected at your discretion. Some models are weak, but light and mobile. Others are relatively large in size. All this must be taken into account.

Do-it-yourself pipe bender from a jack: homemade

By definition, a pipe bender is a device for bending pipes, profiles, metal rods and parts at any angle. The main indicator of the quality of the device is the non-creasing of products during operation. It is not profitable to buy equipment for carrying out a small amount of work, but if you have a jack at home, then with a little skill you can get a good pipe bender from a jack, made by yourself.

Device transformation options

Before you start working with your own hands, you should decide on the type of pipes that need to be bent. This is due to the fact that unequal performance of products requires the use of different types of efforts. If you intend to work with suture models, then bending should be carried out so that the seam is located on the side. Standard bending most often leads to the formation of “waviness” on the inside of the element.

According to possible transformation, hand-type instruments differ in three modifications:

1. Changing the model with additional people. One will pull the pipe using a winch, the second will provide pushing movements. But it is possible to do the work yourself if you connect the device to the gear motor motor.
2. If it is necessary to bend pipes of various diameters, it is necessary to equip the device with replaceable upper rollers. This pipe bender, made with your own hands from a jack, allows you to set the required parameters and adjust the height.
3. If you add a motor to the jack, you will get a good device for preparing profile pipes.

It is possible to make a pipe bender in different ways, but it is worth taking into account your own resources and goals.

Making a pipe bender from a jack: features, tools, stages of work

In order to make a bending machine, you need to prepare a hydraulic jack, a channel, 2 wheels, a shoe and metal plates. Now you should do the following:

1. Having determined the height of the jack, weld the channel - the structure should look like a rectangle;
2. Place the unit on a plane and secure it with plates;
3. Find rollers of the right size. This is required for a tight fit around the pipe. It’s a good idea to have a supply of rollers for bending workpieces of different sections and diameters;

In order for a homemade pipe bender from a jack to turn out correctly, you will additionally need the following components

• cement mortar;
• cuttings of pipes with thick walls or channels;
• several pairs of wheels;
• winch;
• concrete slab;
• metal jumper;
• gear motor;
• engine;
• Hydraulic jack that can withstand a load of 2-5 tons.

Now you can start making pipe bending equipment yourself. Stages of work:

1. 4 racks are attached to the frame welded to the height of the unit;
2. beam parts in the shape of the letter “P” are laid on the racks;
3. grooves are drilled in the beams for thrust elements in the top row;
4. Using the same pattern, holes are drilled to adjust the bending radius;
5. The jack is fixed to the frame with your own hands using plates and bolts, but allows for easy dismantling for use for other purposes.

Important! For the supporting elements of the upper rows, cuttings of blanks with a cross-section of 40 mm are excellent; they are suitable as components for bending square and rectangular profiles. And so that the thin-walled pipe does not bend at the points of connection with the support, wheels with a radius identical to those of the bent pipe are needed.

All that remains is to make a “mushroom”, which represents a replaceable part of the pipe bender, placed on top. The radius of the part must coincide with the bend data and it is best to make several of these elements with your own hands. In general, there should be at least three of them: small, medium, large. Making them is simple and easy with your own hands: buy a pipe with a bend angle of 90 degrees - this is the diameter that corresponds to the size of the area that is shown for bending. The rest can be cut off.

Now you need to cut the prepared bend in half lengthwise. A piece of pipe 3-4 cm long is welded to the bottom (right in the middle), and the diameter should be such that the movable part of the jack can be easily inserted into it. Side gussets will help strengthen the structure. Now you have a DIY pipe bending machine, and you can use it for work.

How to make equipment for bending pipes with your own hands: elementary designs and operating principles

Metal pipes, especially copper, are quite thin and elastic. It seems that giving them the desired shape is a simple matter: the angle required in a particular communication branch can even be set manually. In fact, correct bending of pipes is a condition for full and long-term operation of the unit.

Violation of technology will lead to rapid wear and tear and frequent accidents. Installation teams that offer professional services for laying heating communications and water pipes have similar equipment.

A craftsman who decides to independently provide water to a private home or cottage will be helped by a homemade pipe bender, which can be assembled from scrap materials.

Requirements for a pipe bender

Pipe bending equipment differs in operating principle, power, energy source and size. This is due to a significant difference in the characteristics of the pipes used in construction. While a compact manual pipe bender is sufficient to create an angle on a thin-walled copper tube, a steel sewer element can only be processed on a machine with high power and a hydraulic or electric drive.

The last design is quite difficult to make at home, but if you want, you can do this kind of work. But most often the question of how to make a homemade pipe bender arises when installing a regular water supply with an elbow of small thickness and diameter. Therefore, the bending structure can be assembled manually without the use of machinery.

Calculation of the permissible minimum angle for steel pipes

A homemade pipe bender must meet the following requirements:

• smoothly bend the fixed element without forming folds or cracks on its surface;
• a homemade pipe bender designed for a round pipe should not change the internal diameter at the bend site;
• do not thin the material on the outside of the fracture;
• ensure the permissible radius of curvature.

Naturally, the device must be durable to withstand the planned loads. They depend on the wall thickness of the pipe being processed, its diameter, and material.

DIY making

When deciding how to make a pipe bender, you will have to decide on its location.

The length of the knee to be bent and the scale of the work determine the choice of the assembly location: a cramped room is not a good idea both due to the lack of space and the risk of damaging surrounding objects with elements.

The device can be placed in a garage, outbuilding or even outdoors. Only devices that are afraid of dampness need to be put away in a dry place, and the simplest pipe benders are not one of them.

Template technique

Pattern bending is an elementary technique available to a craftsman without the skills to design devices of any kind. It is based on a template, that is, the shape into which the pipe will be bent. It is only necessary to calculate the diameter of this structure, focusing on the characteristics of the pipe. Having calculated the minimum allowable angle and drawn the desired circle for clarity, you can begin to design the most important element of the template pipe bender. The material for its manufacture can be waste:

• wooden disk;
• a circle assembled from planks cut according to a diagram and secured in accordance with it;
• a series of metal pins driven into the surface with sufficient strength;
• metal hooks fixed in the required arc.

Before work, you will have to make sure that the assembled template can withstand a significant load and will not collapse under pressure. The support on which the structure is mounted must be stable and securely fastened. A durable plywood panel, a concrete slab, or even the wall of one of the agricultural buildings will do.

The pipe will be wrapped around the template, so a reliable stop is mounted on one side of the structure: the distance from the fixing element to the template must correspond to the diameter of the pipe. A system of belts is attached to the second side to make work easier. A copper tube can be bent with the effort of one person; for a steel element such effort will not be enough; a hand winch will help out by pulling the end of the pipe tightly to the template.

It is important to remember: the diameter of the pipe will be maintained if a flexible but durable element is placed inside it. Since it is quite difficult to choose the diameter, craftsmen often simply pour sand into the cavity.

The design of a homemade crossbow pipe bender from a jack

Pipe bender from a jack

The design of such a device is quite simple, and if you consider that its productivity is quite high, you can calculate the savings on ordering work from professionals. The essence of the technique is to extrude a section of pipe between two fixed points.

Professional equipment of this type is called a crossbow because of its specific shape: the “firing”, or rather extruding, tip acts as an arrow. If you create a pipe bender from a jack, he will play this role.

You only have to weld the frame that tightly secures the bending element.

The frame is a U-shaped structure of two parallel welded supports, the jumpers between which will serve as stops. A jack is installed exactly in the center between them.

The pipe is brought under the jumpers and clamped from below with a jack. Gradual pressure leads to its curvature. Filling with sand or installing a drone is necessary, otherwise the risk of deforming the pipe is quite high. The disadvantage of the method is the approximate nature of all actions and the lack of accuracy in the work: a homemade pipe bender with a jack does not make it possible to measure the angle during processing.

Homemade pipe bender based on a clamp

Hydraulic machine

If you have engineering skills and the ability to weld a truly large-scale structure, you can make a homemade pipe bending machine that can cope with professional volumes of work: the drawings and design of such machines are posted online along with photographs of the models. The technology for bending metal pipes using a clamp and three rollers is reliable.

Two of them rotate with the help of a handle and reduce the distance between themselves, and the third remains stationary, providing a bending angle. The system is equipped with a chain and sprocket gears that drive the mechanism. The machine is simple, reliable and trouble-free.

Homemade pipe benders are not designed for industrial use. Their disadvantage is obvious: all work is carried out “by eye”, while professional equipment ensures micron accuracy. But for installing your own water supply at your dacha, these devices will be quite sufficient.

Homemade pipe bender from a jack

It’s not that difficult to make a homemade or even a professional pipe bender with your own hands in order to be able to bend pipes at a given angle and, importantly, with a given bending radius.

Making a pipe bender with your own hands is not so difficult

Contrary to popular belief that this device is most often used when performing plumbing work, in such cases various fittings and elbows are usually used - pre-bent sections of pipes manufactured in industrial conditions. However, there are restrictions on the use of bends, which are determined by their standard characteristics:

• rotation angles (can be 45, 60, 90 and 180 degrees);
• bending radii (bends with bending radii of 1.0 DN and 1.5 DN are available);
• use of welding.

Not in all situations such parameters can satisfy those who need to give a pipe structure the required shape. It is in such cases that a mechanical pipe bender (or manual pipe bender) comes to the rescue.

Those owners of dachas and private houses who are going to independently produce various arched structures, greenhouses, custom-shaped fences and much more cannot do without a machine for bending steel pipes.

In this article we will thoroughly examine how to make a pipe bender with your own hands. After all, a homemade pipe bender can be used not only at home, but also in semi-professional activities, since its design is not sky-high in complexity, and commercial devices for bending pipes are quite expensive. Therefore, by making a manual pipe bender with your own hands, you will save a lot of money.

Two pipe benders: manual and electric

Classification of pipe bending devices

Devices for bending steel pipes are classified:

• by degree of mobility (stationary and portable);
• by type of drive (manual, electric, hydraulic, electrohydraulic);
• according to the method of influence (running in (roller), winding, impact with a rod (crossbow), rolling).

The essence of how a pipe bender influences a pipe is as follows.

With this method, one end of the pipe is clamped, and a stationary template is used to give it the required bend. Pressure rollers are used to roll the product around the template.

Drawings of a rolling pipe bender

In such a device, the pipe is pressed against a movable template (roller), on which it is wound, stretching between a rotating roller and a special stop installed at the beginning of the bending point.

Diagram of a pipe bender operating on the winding principle

In such a pipe bender, the pipe rests on two stationary rollers, and bending is performed by a template, which is attached to a movable rod. The template presses on the middle of the fixed section of the pipe, thereby giving it the required bending angle.

Diagram of a crossbow pipe bender: 2 - jack, 3 - shoe (punch)

The required bending radius is obtained using a three-roll device, the basis of which is two support rollers and one central roller. The central roller exerts pressure on the pipe, the position of which determines the radius of its bend. A rolling pipe bender is more universal; in all other machines, the bending radius depends on the template used.

Compact size manual rolling pipe bender

The manufacture of a pipe bender operating on the winding principle is not simple, so such a device is made mainly in an industrial way.

The crossbow method has another significant drawback: the pressure from the rod with a template attached to it, called a shoe, is concentrated in its upper part.

This method of acting on the pipe leads to its significant stretching along the outer radius of the bend, which may be accompanied by a decrease in wall thickness and even its rupture. It is especially not recommended to use the crossbow method for bending thin-walled products.

An example of a homemade rolling (rolling) type pipe bender

A machine operating on the principle of rolling (rolling) practically does not have all of the above-mentioned disadvantages; this technology is used in the production of bends in the factory.

A DIY pipe bending machine can have a different design. You should choose its type based on the bending radius of the steel pipe you need.

There is a list of recommendations, in accordance with which the choice of a specific model of device for bending steel pipes is made. Important parameters that need to be taken into account are the thickness of the pipe walls and its overall diameter.

Before starting to work with a pipe bender, it would not hurt to familiarize yourself with the data in the table showing the maximum possible radii for bending steel pipes.

Dependence of the bending radius on the diameter and wall thickness of the pipe

To obtain a bend radius smaller than that specified in such recommendations, it is necessary to use a mandrel pipe bender or hot rolling, which is used mainly in production conditions. A device with a mandrel is more difficult to create at home, so they are much less likely to be made independently, giving preference to rolling ones.

In order to independently hot-roll a pipe, you can resort to using a home-made pipe bender, but provided that it is made entirely of metal and its frame is highly reliable. To perform such a technological operation, you will additionally need a blowtorch or gas burner.

Making a simple template-type pipe bender

A simple rolling pipe bending machine can even be made from wood. Naturally, this will be a manual pipe bender, the design of which may not even include a pressure roller if it is used for thin-walled products. The template for such a device is made from a wooden board, the thickness of which should be such that it exceeds the diameter of the pipe itself.

Wooden template for a simple manual pipe bender

For ease of work, it makes sense to consider profiling the template from its end in order to avoid the pipe jumping off during bending. For these purposes, you can fold two boards, first sawing one edge at a time, thus creating a kind of gutter. A pre-drawn drawing will help avoid mistakes.

When using such a pipe bender, the template is attached to a reliable base, and a stop is attached to the left side of it (for right-handers). The pipe that needs to be bent to the required radius is placed between the template and the stop and carefully bent, making sure that it does not jump off the template.

Collapsible hook template

With the help of such a pipe bender, made from scrap materials, you can bend along a large bend radius. You can avoid making a wooden template and simplify the device by replacing it with metal hooks fixed to the base, located in a circle with the required bend radius. This device is convenient in that the dimensions of the bend can be changed at any time by placing the stop hooks around a circle with a different radius.

Armed with a manual winch, you can significantly expand the range of work performed due to a noticeable increase in traction force for bending pipes.

The winch will help expand the functionality of the simplest manual pipe bender

Pipe benders with pressure roller

A more complex design is a manual pipe bender, which uses a pressure roller. To make such a device, you can use both wood and metal.

For pipes made of soft materials (for example, copper), wood rollers are the best option, since they do not cause metal deformation. It’s not at all difficult to make such videos at home if you use photos or drawings of similar devices, which are posted in large numbers on the Internet. The manufacturing material can be thick boards or several layers of plywood.

A homemade pipe bender of a similar design, which is based on rollers - movable (pressing) and stationary - allows you to bend round pipes that even have a significant diameter.

Do-it-yourself pipe bender for a profile pipe: manufacturing methods – Repair tips

Anyone who likes to make various products and designs on their own is often faced with the need to bend a profile pipe into an arc.

It is impossible to do this smoothly and accurately without special devices, so there is a need to make a pipe bender for a profile pipe with your own hands. Craftsmen have come up with quite a lot of designs for this device.

Many of them can be done independently. At the same time, they do not require large amounts of money and are easy to manufacture and use.

Pipe bender device with shoes for different bending angles of pipes

Helpful advice! Before you start making a pipe bender, you need to understand their types. You should choose the one that is most suitable for you in terms of functionality and is feasible for you to manufacture yourself.

If we are talking about industrial devices, they are divided into several types according to the method of drive, as well as the type of bending.

Classification by drive type

The machines are: hydraulic, electromechanical and manual. Machines based on hydraulic drive are manual and stationary. Their power is enough to easily bend pipes even with a 3-inch diameter. Hydraulic pipe benders are used in professional activities in specialized industries and are capable of performing a very large volume of work.

Hydraulic pipe bender for bending water and gas pipes at an angle of up to 90°

Electromechanical devices can be used to bend almost any pipe, even with very thin walls, which is beyond the power of hydraulics. After all, electronics make it possible to very accurately calculate the force and bending angle, which prevents the material from tearing. Pipes bent by such devices do not show the slightest signs of deformation.

Electromechanical pipe bender for PEX/AL/PEX pipes and bending angle up to 180°

Manual pipe benders are used only for bending small-diameter pipes made of polymers, stainless steel or non-ferrous metals. They operate mainly from the electrical network. They are easy to use and do not require much physical strength to operate. It is quite possible to make such pipe benders for a profile pipe with your own hands.

Hand tool for bending rectangular profiles and steel pipes

You can bend a pipe using the device in various ways. Depending on this, the following types of pipe benders can be distinguished: crossbow, spring, segment, mandrel.

Crossbow devices are equipped with a special shape, which is the bending element. It is designed for one diameter or section of pipe. To bend a pipe of a different diameter, the mold must be replaced. Spring devices are equipped with elastic springs that allow plastic pipes to be bent without deformation. Segment ones are equipped with a special segment that pulls the pipe around itself, bending it at the desired angle.

The principle of bending a profile pipe using a homemade tool

You need to understand that the method and angle of bending of the pipe depends on its characteristics. There is even such a value as the minimum bending radius, with a further decrease in which the pipe becomes deformed or simply breaks. This indicator depends on the wall thickness, material and cross-section of the pipe.

Helpful advice! Regardless of whether or not it is possible to bend the pipe more than prescribed, it should not be done. Even if you can bend the product without damage, the quality of this bend will be poor, and this will show up sooner or later. Therefore, the minimum radius must be adhered to.

One of the options for using a bent profile is arranging a greenhouse

Now let's look at some homemade options for pipe benders. The simplest option provides the possibility of bending the pipe using a template to a given radius. This technology is quite suitable for bending steel pipes, not just aluminum ones. The template is simply cut out of boards, the thickness of which is slightly greater than the diameter or cross-section of the pipe that needs to be bent.

These boards are securely fastened together so that the pipe cannot jump out of them during the bending process. To form a gutter, the boards to be fastened are simply cut at a slope for a round pipe. Then, the finished wooden template is attached to a table or other similar base. A stop is attached next to the template to secure the pipe.

A self-built pipe bender for a profile pipe of this type is capable of bending even fairly thick-walled pipes if a winch is used. If the pipe is profiled, then bevels are not made when cutting boards. Instead, the pipe is secured using several restraints.

Drawing with dimensions for making a pipe bender with your own hands

Using wood, you can even build a rolling pipe bender by turning wooden rollers. They can also be made from bearings or polyurethane. In general, the complexity of making homemade pipe benders depends in some way on the flexibility of the pipe. Pliable options can be bent on wooden devices without much difficulty simply with your hands, but for rigid pipes you will need more complex devices with metal parts.

Making a homemade hydraulic pipe bender

If you decide to make a real hydraulic pipe bender, you need to get a hydraulic jack, a channel, two rollers and a shoe. In addition, you will need several metal plates made of steel more than 3 mm thick.

Diagram and principle of operation of a homemade hydraulic pipe bender using a jack

Using a welding machine, a rectangular structure is created from the channel, the height of which coincides with the height of the fully extended jack. It is installed on a rigid base and securely secured with metal plates.

A jack must be selected with a lifting capacity of at least 5 tons. It is designed to act as a pusher. The main task here is to find the most suitable videos. The difficulty is that only with the most precise circling of the pipe with rollers can a truly high-quality bend be obtained. If you find different rollers and make them removable, you can bend pipes of various sections and diameters.

An example of a DIY device for bending metal pipes

The advantages of a hydraulic, self-built pipe bender for a profile pipe are: ease of manufacture, availability and low cost of the jack and parts. This device allows you to bend any profile and round pipes in a cold state with high quality.

How to make a rolling pipe bender yourself

The process of bending a pipe in a rolling machine is as follows. The pipe is laid on side rollers, and a third one is lowered on top of it, fixing the product in a given position. When we start to rotate the handle, the chain sets the shafts into rotation, and the profile or round pipe bends at the required angle.

Step 1: creating a pipe bender base from a steel channel 80x80x4

To make such a device you need:

• grind rollers and races for bearings. This task can be entrusted to a turner, who, according to the drawings, will do the job in the best possible way. The device will have three shafts, one of which is suspended on springs, and the other two are fixed in the sides of the frame;

Step 2: making the screw mechanism housing

• prepare a shelf from a 50 mm channel. It has the shape of a rectangle with sides 100x30 cm. Holes are made in it for attaching shafts and threads are cut to adjust the position of the pressure shaft;

Step 3: Create a Standard Threaded Screw

• fasten all parts together using a welding machine;
• the shelf with the pressure shaft is suspended on springs, and the side shafts are connected through sprockets with a chain. A handle for rotation is welded onto one of the shafts;

Step 4: Making the Center Drive Roller Rotary Handle

• mount the jack so that it can be used to easily adjust the clamping force.

Helpful advice! You are unlikely to be able to make a rolling pipe bender without drawings and calculations. If you do not have engineering knowledge, then it is better to find ready-made documentation, according to which you can make the machine.

Step 5: assembling all the parts of a homemade rolling pipe bender

It is quite possible to make a pipe bender for a profile pipe with your own hands. Its complexity depends on what purposes you need it for. If these are only one-time actions, then wooden structures are sufficient. If you are engaged in the manufacture of pipe products on an ongoing basis, then you will need a more complex unit.

How to make a pipe bender at home - types of pipe benders and methods for making them

:

A device that allows you to bend pipes at a certain angle or with the desired bend radius can be made with your own hands. Moreover, it can be a professional pipe bender or for home use.

A pipe bending device is popular when installing or repairing plumbing systems, when there is a need to use various connecting elements or bends.

What is it for

In industrial conditions, these elements are produced in accordance with certain standards, therefore they have standard parameters:

• Rotation angles of 450, 600, 900 and 1800.
• Bend radius.
• Use of welding equipment.

But in some situations, individual parameters are required. Therefore, a manual pipe bender comes to the rescue, allowing you to give the desired shape to the pipe product. Using this device, owners of private houses and summer cottages can bend pipes for greenhouses, arched structures and non-standard shaped fences. In this regard, the question arises of how to make a pipe bender at home.

You can make a pipe bender yourself; its design is not particularly complicated. Factory analogues have a fairly decent price, so a do-it-yourself pipe bender will save a decent amount. A homemade mechanism for bending steel pipes can be used at home and in the semi-professional field.

Types of pipe bending mechanisms

Devices that allow you to bend a steel pipe to a certain radius are divided according to the following characteristics:

• Mobility. Pipe benders can be stationary or portable.
• Type of drive. Depending on this feature, manual, electric, hydraulic and electro-hydraulic devices are distinguished.
• Method of influence. The tubular product is bent under the influence of rolling, winding, rolling and rod.

Before you make a pipe bender at home, you need to understand how the device affects the workpiece and become familiar with each process separately.

Run-in

This method involves performing the following actions: one end of the tubular product is pressed against a stationary template and the pipe is rolled around it using pressure rollers.

Winding

This type of device has a movable template. A pipe is directly wound onto it, which passes between the template and a special stop located at the beginning of the bend.

Crossbow type pipe bender

This device is equipped with two fixed rollers and a template mounted on a movable rod. When the rod presses in the middle of a certain section, the pipe bends.

Rolling

The design is made on the basis of two support rollers and one central roller. This three-roller mechanism helps to obtain the required radius when bending as a result of pressing the central roller on the pipe, the position of which determines the bending radius. This makes it possible to call this type of pipe bender universal, since all other types bend the pipe according to a specific pattern.

A pipe bender operating on the winding principle is quite difficult to make at home, so industrial enterprises produce such mechanisms.

When using a crossbow pipe bender, it is worth remembering that the impact of the rod on the pipe product can cause the material to rupture. Consequently, these mechanisms are not suitable for bending products with thinner walls.

The rolling device has no significant disadvantages; it is used in the factory production of bends.

The design of a machine for bending home-made tubular products can be varied. The correct device should be selected according to the required bending radius. In addition, it is worth studying the recommendations for choosing a device, and also taking into account the main parameters of the pipes used: diametrical cross-section and wall thickness.

Reliable do-it-yourself pipe bender using a jack - Tool Stroy

Bent pipes are used for wiring plumbing and heating systems, as load-bearing structures for greenhouses, greenhouses, and small architectural forms on sites.

The work is carried out with a special tool - a pipe bender. It can be purchased in a store, but economically the purchase is not always justified.

For the needs of households and small workshops, it is more advisable to make a homemade pipe bender.

Purpose and types of structures

Pipes are bent in cases where the use of factory fittings and bends when carrying out work with utility networks is not possible. Using a pipe bender you can:

• set a non-standard rotation angle;
• set a non-standard bend radius;
• avoid the use of welding and threaded connections.

The main criterion by which devices differ from each other is the method of influencing the deformable pipe. These include running-in, winding, rod pressure, and rolling. The machines are produced on the basis of manual, hydraulic, electric, electro-hydraulic drive. They can be stationary, mobile (on a wheel base), or portable.

Running in is carried out using a stationary template around which a pressure roller is rotated. The profile of the elements is selected according to the cross-sectional shape of the pipe, fixed between the template and the roller using additional fasteners. The winding template rotates around its axis together with a deformable pipe, fixed by a friction clutch and pressure rollers.

The principle of rod pressure is used in crossbow-type pipe benders. The pipe is supported on rollers installed at the required distance from each other.

A jack is used as an active element; a shoe (punch) is attached to it, pressing on the bent element in the middle.

Since pressure is applied to a limited area of ​​the product, there is a risk of thinning the pipe walls at the point of contact with the shoe.

Pipe bending machines for rolling (rolling) consist of three rollers: two supporting and one central. The central roller applies pressure and sets the radius of curvature of the product.

Rolling machines do not require special templates; they can be used for pipes of various profiles, materials (including stainless steel) and different thicknesses.

The minimum possible bending radii are given in the table.

If the required bending radius is less than the minimum allowable, use a mandrel pipe bender. It allows bending in zones of plastic deformation under all-round uneven compression.

A rod with a fixed mandrel is inserted into the pipe - a steel mandrel with hinged rings at the end.

It is quite difficult to create such a device at home; the design is often simplified to the detriment of the quality of the finished product.

Break-in tool

This device is suitable for small cross-section pipes. Running in is carried out using the operator’s muscular strength.

Both wooden (including plywood) and metal parts are used as working elements. Wooden templates and crimping disks do not cause local deformation of the pipe metal and are considered optimal.

Used roller bearings can be used as metal pressing discs.

You can make a pipe bender with your own hands . A hole is drilled in the massive base, onto which a template disk and a U-shaped frame with pressure rollers are installed. The template should rotate freely around its axis, the U-shaped frame rotates around the template. The rollers are tightly fixed to the pipe using a bolt.

A handle extends from the frame; it will also serve as a lever when bending. It is important to ensure high strength of the handle and reliability of its attachment to the frame: under heavy loads, this structural element will be the first to break. The base is also provided with a clamp in the form of a clamp or bolt clamp.

It prevents the pipe from rotating after moving parts.

A special case of such a device is a manual lever pipe bender . It consists of two levers connected by a hinge. It does not require a base, is portable and easy to use. Using a notch on the central part, you can set the required angle of rotation.

Reliable pipe bender with your own hands using a jack

A pipe bender is a special machine equipment designed for bending pipes, profiles, metal rods, and parts at any angle. During such events, the products used are not crushed.

A pipe bender is a device designed for bending pipes, profiles, metal rods, etc.

It is possible to make a pipe bender with your own hands from a jack by understanding the work flow diagram below.

Using pipe benders

Technology of working with a manual pipe bender.

Pipes are always in high demand in the construction market. They are actively used both in everyday life and in industrial conditions. Such products make it possible to install gas pipelines and water pipelines; they are used to build fences, gazebos, greenhouses, sheds, and garden furniture. By making a pipe bender with your own hands, you can purchase the necessary equipment for your home, which will always be at hand.

This device allows you to bend any profile pipes according to the set radius. With the help of a pipe bender, the fittings are easily deformed, and such materials are subject to changes. like stainless steel, aluminum, metal-plastic. Bending is carried out in accordance with the specified sizes and shapes.

The bending equipment in question will be an excellent help in any private workshop. It will help produce frames for bicycles, motorcycles, as well as exhaust devices, visors and railings. This device is used to repair bearings, oil seals and rubber bushings.

Table of pipe bending radii.

Despite the apparent simplicity of bending pipes, carrying out such a procedure is not easy. Incorrect assembly of the tool will lead to the appearance of defects on the products, which will immediately affect their strength.

To make the desired version of a pipe bender, you should decide on the type of pipes that will be subject to changes. This is due to the fact that products with different indications, such as thickness and diameter, require different types of effort.

Most often, specialists work with suture material. These products should be folded in such a way that the scar is on the side. And a standard bend most often leads to the formation of metal tubercles on the inside of the product. Such sagging does not form on the inner sides.

Options for transforming pipe benders

A hand-held tool can be transformed. There are 3 options for such modifications:

Pipe bender assembly diagram.

1. 2 assistants will help change the model, one of whom will be busy pulling the pipe, thereby using the winch. The other one will push her. The work can be carried out independently, without the involvement of other people, for which the device is connected to an engine that has a gear motor. A chain drive drives the wheels.
2. The use of pipes of unequal diameters provides the basis for replacing the upper rollers with a unit that every car has. Such a pipe bender made from a jack helps to establish the required pressure indicators and height adjustment.
3. By constructing such a device, consisting of an engine and a device for lifting a car, you can purchase a valuable device with which blanks are made from profile pipes.

You can make a pipe bender with your own hands in different ways. When choosing, you should consider your own resources and goals.

Features of hydraulic pipe bender

To make such a bending machine, you need to prepare a hydraulic jack, a channel, 2 wheels, a shoe, and metal plates. Based on the height of the jack used, the channel is welded. The resulting device must have a rectangular configuration. The hydraulic unit is placed on a plane and firmly fixed with metal plates.

It is desirable that the jack used can withstand loads of up to 5 tons.

Manual hydraulic pipe benders.

This device acts as a pusher. Finding the appropriate size videos will be a difficult task. In order for the bend to be of the highest quality, it is important to achieve a tight fit around the pipe.

It is advisable to make a reserve in the form of several rollers that can be easily removed. These wheels allow you to bend any pipes, regardless of the quality of the materials and the diameter of the products.

A pipe bender made from a hydraulic jack is distinguished by a simple manufacturing scheme, affordable cost of the unit itself and spare parts. Such a device helps to deform pipes during repair work indoors, when replacing plumbing, or restoring a car.

Equipment required for making a bending machine

Before starting work, you should select the appropriate drawings, the use of which will greatly facilitate the work. First, a cement mortar is prepared in a ratio of 1:4. It is thoroughly mixed in any container. If possible, you should prepare scraps of thick-walled pipes; if they are unavailable, you can take channels.

For work you also need such devices as:

Drawing of a bending machine.

• wheels,
• winch,
• concrete slab,
• metal jumper,
• gear motor,
• engine,
• jack.

The last detail is selected especially carefully. To do this, you can use the existing unit, which is removed from the frame and used for the necessary purposes. Here you need a hydraulic jack, designed for a load of 2-5 tons.

Then the frame is made. It is selected to match the height of the prepared unit and has the shape of a trapezoid. As a material, you can take corners with a shelf of 45 mm.

First, a rectangular shape is welded, then 4 racks are attached to this shape, and 2 beam parts, the appearance of which resembles the letter “P,” are placed on them, in turn. Then the channel is used. In the beams, using a drill, grooves are drilled for the thrust parts in the top row.

Openings are made in the same way to adjust the bending radius. The jack is fixed to the frame using plates and bolts. It should be easily removable in order to be used later for other purposes.

Cut blanks with a diameter of 40 mm are used as supporting elements of the upper rows. They are ideal as components that bend profiles of square and rectangular configurations. At the moment of deformation of a thin-walled workpiece, it can bend at the points of connection with the support. Here you will need special wheels, the radius of which is equal to the pipe.

At the last moment, the “mushroom” is made. It is an easily replaceable pipe bender part that fits on top of this machine. Its radius coincides with the bends. It’s good if there are several such elements.

Ideally there should be three of them: large, small and medium. You can make such “fungi” yourself. You can purchase a pipe bent 90° at any hardware store. Its diameter corresponds to the size that should be subject to deformation.

Excess parts should be cut off.

The prepared bend is cut into 2 parts to obtain longitudinal parts along the radius. Taking the lower part, a small element from a pipe 3-4 cm long is welded to the middle. The transverse size should be such that the movable part from the jack fits into it. The gussets located in the side parts will strengthen the structure. The pipe bending machine is ready and can be used for work.

How to make a homemade pipe bender: advice from experienced people

Metal pipes in a summer cottage are the basis of most buildings. The frame for a greenhouse or hotbed, fences and pens for birds, the bases of gazebos and canopies - all this is made from round or profile metal products.

Frame for pipe bender

It is no secret that the arched shape of the same greenhouses or canopy over the porch reduces rain and snow loads, and is therefore very beneficial. But to form it, you need to bend the pipe.

Pipe bending: limitations

All types of pipelines are subjected to the operation: steel, aluminum, metal-plastic and copper. And not only during the construction of the frame, but also the formation of water supply and sewer systems. The fact is that any mechanical joining of pipes is a weak point of the system, and the fewer there are, the better.

Pipes of different thicknesses and diameters, of course, bend differently. The determining criterion here is the minimum bending radius. This is a reference value and can always be found.

If this limitation is not observed, the quality of the product suffers: the resulting stress on the surface destroys the pipeline no worse than corrosion.

Pipe benders: options and manufacturing

To give pipes a curved shape, a special device is used - a pipe bender. Such a device can be found in a store, but in the vast majority of cases, home craftsmen build it with their own hands.

Wood template

Quite effective for working with small diameter products.

1. A template with the required radius is cut out of the boards. The thickness of the board is slightly larger than the size of the pipeline. To prevent it from slipping off the edge, the boards are cut at an angle.
2. The template is fixed on any base - a wooden table, a workbench.
3. On one side of the template, a wooden stop is fixed at such a distance that a pipe can be placed between the template and the stop. The homemade pipe bender is ready.

The pipe is inserted into the gap, as shown in the photo, and carefully bent according to the template.

A more universal version of the device is metal hooks attached to a piece of plywood: they can be rearranged, creating a template with a given radius.

Concrete universal pipe bender

Here a concrete slab is used as the base. There is no need to make a drawing.

1. A grid is marked on its surface - 40*40 or 50*50 mm. At the intersection points, holes are drilled for reinforcement.
2. Metal pins are driven into the holes.
3. The pipe is inserted between the pins and bent in the desired direction. The radius is selected by moving diagonally. You can make this device with your own hands in a few hours.

This pipe bender works with products up to 25 mm in diameter.

Option with jack

A jack is used as the main working unit.

1. Ribs - metal pins - are fixed on the vertical surface.
2. A jack is mounted under them and exactly in the center on some rigid base.
3. A section of pipeline is fixed above the jack and under the pins. The jack rod rises and the pipe bends.

Since the jack develops considerable force, this homemade device can be used to work with large-sized products. The photo shows a sample.

Roller pipe bender

Making it yourself is a little more difficult, but its bending accuracy is much higher. To perform this you will need experience with a welding machine. It is recommended to make a drawing, since it is important to maintain the dimensions.

The device operates on the principle of a rolling mill: the section is placed on moving rollers, and the third roller, the forming one, exerts pressure and gradually bends the pipeline to the required amount.

1. The basis of a homemade pipe bender is a channel of sufficient width. A U-shaped frame is attached to it. In its upper part, holes are drilled for the clamp coupling.
2. Two rotating rollers are welded on top at the same distance from the edge; they are connected by a chain drive.
3. A metal pin is fixed into the clamp coupling, and a third roller is mounted at its end. On the other side, the studs weld the handle.

The piece is placed in the gap between the rollers, and when the handle is rotated, the clamp presses the product against the third roller. The pipe moves on feed rollers and bends as required. This operation is repeated several times, since the initial force is small. The bend radius is limited to 90 degrees.

Hydraulic pipe bender

The design of the device is the same as that of the roller one, so the same drawing can be used, but the device is driven not by a manual drive, but by an electric one. The device is much more efficient, but also somewhat more expensive to manufacture.

1. The feed shaft is fixed to the base. At one end there is a pulley for the electric motor belt drive, and at the other end there is a drive sprocket for the chain drive.
2. The second shaft is installed, and the driven sprocket is mounted on its end.
3. The deforming roller is fixed in both the upper and lower parts of the apparatus. Bottom placement is preferable, but then you will need to make holes for the rod to move.
4. The hydraulic rod is secured to a clamp.
