How to rivet blind rivets correctly

Manual riveter: how to use, choose, rivet rivets, principle of operation and drawing device

To replace the familiar, old and ineffective ones, new tools appear in our lives. They become necessary for solving simple household chores and indispensable when performing professional-level tasks.

What is a riveter?

One of these tools is a riveter, which is designed to connect two or more parts.

Now it is difficult to overestimate the importance of rivet work where it is impossible to connect thin parts in other ways.

Riveted fasteners are indispensable in construction work - forming fences from profiles, riveting steel sheets or metal materials, installing ventilation facades. In industry – connection of housings in household equipment, cars, heating installations. In everyday life - when carrying out minor repair work.

This method makes the connection reliable and resistant to vibration. The connection will not burst when the load increases, which compares favorably with a welding seam.

Kinds

The range of works that require the installation of riveted seams is very wide. And each process has its own specifics. The correct choice of tool determines with what quality, in what time frame and how much cost it will take to complete the required task.

By type of fastener use

Since the method of joining all types of rivet joints remains banally simple, riveters repeat this entire process, only by “automating” it.

The method remained the same - filling a through hole in the two parts being connected with metal. Only technologically this task is performed in different ways.

The drawing tool, to fill the entire space of the through hole, deforms the metal by pulling it out. And the threaded one fills a through hole using the method of twisting and then tightening. This also causes the connecting metal to flatten.

For these actions, in both cases, special fastening materials are used for drawing and cutting tools, respectively. Let us dwell in more detail on the mechanism of their operation.

Exhaust

The device of the tool is a simple mechanism. A hole is first drilled in the materials to be fastened. The body of the rivet is inserted into this hole. This body is the material with which the through hole will be filled. The rivet maker's jaws grip the rivet rod up to the working part (shoulder).

In fact, the rivet shank is designed to deform the body of the rivet to fill the entire through hole. This is accomplished by the tool's pulling mechanism, which pulls the head of the shank through the body of the rivet toward the base. In this case, the body of the rivet (a cylinder made of soft metal) is easily flared. A tight connection of materials is established between the head of the rod and the shoulder of the rivet body. When the rivet joint is ready, the rivet shank breaks off.

Example of operation of an exhaust device

Threaded

The operating principle of such a tool is also not difficult. A threaded rivet is installed in a hole prepared in advance in the connected parts. The rivet has an internal thread. The riveter screws the holder onto the threads of the rivet body.

Then, using a traction load, we lift the holder. In other words, we use a riveter to pull the holder together with the body of the rivet towards the base (shoulder). This also causes the body of the threaded rivet to flatten. In some cases, the body of the threaded rivet (sleeve).

By food type

The need for combining materials is high - from the domestic sphere to the industrial sphere. At the same time, the requirements for the riveting tool are different. Hand tools can handle light-duty tasks quite well. For more complex tasks, enhanced versions of hand tools or battery-powered tools are available. The requirements for a professional device are higher - since it is necessary to perform a large number of operations.

Summarizing the above, we can distinguish three types of tools based on the type of power supply:

How to use a riveter: types of tools for riveting rivets

In industry, one of the main operations is the connection of structural elements and parts.

One way is to connect using rivets. It is used when it is not possible to weld structural elements, and has many advantages over it. To perform this technology, there is a special tool for riveting rivets.

What is a riveter and its types

A riveter is a special tool (pliers) that works on the principle of a gun, which is designed to connect structural elements and their individual parts when their thickness during connection does not exceed 10 mm.

Basically, with the help of such a mechanical gun, parts are fixed from the inside. The manual riveter is a lever tool in the form of a pistol, consisting of 2 parts:

• a spring mechanism designed to pull the rivet inward;
• lever system used to create force.

There are two types of rivet tools on the market today: threaded and pull-out.

Pull tool

Threading tool

A manual pull-type riveter works by using a pulling force to secure the rivet. Under the action of the lever force, the rivet rod is drawn into its tubular part and is pushed apart by the head of the rod. On the outside, the rivet head is also flattened and creates a strong fixation of the parts.

The principle of operation of a manual threaded riveter is the same, only the retraction of the ball in the working part occurs not due to force, but by rotating the thread in the tubular part of the rivet. That is, it uses a method of fixing the head by twisting the handle. This method is not used often and is mainly necessary for fixing parts that have a small thickness.

Nozzles of different diameters and tail lengths are usually sold complete with the gun.

Types of drive for riveters and their cost

Based on the type of drive device, riveters are divided into:

• pneumatic;
• mechanical (manual);
• electrical;
• battery;
• pneumohydraulic.

The most popular devices in everyday life are those with a mechanical drive. Such instruments have two modifications. One involves working with one hand, and the other with the power of using two hands.

“One-armed” devices also include a model of an instrument called an “accordion.”

The cost of riveters depends on the manufacturer, connection method, model, and drive device. Promoted brands of tools are more expensive than products from unknown manufacturers.

Also, pneumatic, electric, pneumohydraulic and battery devices are much more expensive than manual ones, because they have a more complex design. They are mainly used on an industrial scale.

Blind rivet device

To understand how to use a manual pull-type riveter, you need to know the structure of fasteners, which are rivets specially designed for this method of fastening.

Such a rivet is a fastener consisting of two elements: a hollow cylindrical tube with a head at the end and a metal rod. The hollow cylinder is called a rivet body (bushing). The diameter of this cylinder indicates the size of the rivet hardware.

The hollow hole inside the cylinder extends through the entire body, including its head. The metal rod looks like a nail with a rounded head. It is inserted into a cylindrical hole and retracted until the head stops using a latch.

Threaded rivets , intended for a manual pull riveter, have a thread inside a cylindrical body. The rod is also threaded and is inserted into the cylinder by screwing.

To create a strong connection, a bolt or screw is most often screwed inside. Sometimes such a rivet is called a blind rivet. It is considered more durable than just exhaust.

Blind rivets are made from different materials. Steel, aluminum or copper alloys are used for the sleeve. It is very important that the sleeve material does not cause corrosion of the metal from which the parts being connected are made. This means that when they come into contact, they should not form a cathode-anode pair.

The rod must be made of steel, the strength of which far exceeds the strength of the body. The rivet body cylinder can have different diameters and lengths. These dimensions are the main characteristics of such products. They are paid attention to first of all when choosing. The diameter of the cylindrical body must correspond to the holes for fasteners.

In order for the cylinder to fit freely into the hole, it must be slightly larger than the diameter of the rivet body. Typically the error is 0.1 – 0.2 mm. The length of the body should consist of the total thickness of the parts being connected and an allowance for the amount of riveting. An allowance of up to 1 mm must be provided for this.

Connection stages using a riveter

How to use a riveter can be seen using the example of manual fastening of parts. The connection process must be carried out in the following order:

• surface preparation;
• marking and drilling holes;
• installation of fasteners.

Preparation of surfaces includes their careful leveling so that the parts rub together as much as possible.

In order to accurately drill holes without displacement, they need to be placed on a flat plane, it is better to take a piece of wood, and securely fix it on it. Then mark the locations of the holes. After this, they are drilled using a drill, maintaining maximum positional accuracy on all connected parts.

To ensure that the hole size meets the required parameters, you need to take a drill with a slightly larger diameter. For example, to produce a hole with a diameter of 3.8 mm, the drill must have a diameter of 4 mm.

After drilling the holes, you need to “try on” the selected fasteners. The head of the rivet should fit snugly against the surface around the edge of the hole and completely cover it.

Installation of rivets

Installation of rivets is carried out as follows:

• the cylindrical body of the rivet is inserted into the drilled holes of the parts being connected;
• the rod passing through the entire body is grasped by the lips or the riveting head of the rivet tool at the base of the cylinder head;
• with the help of force, the rod is gradually pulled through the body of the rivet, expanding it with its cap (head) and deforming the end of the cylinder. In this way, the reverse wide part of the rivet is formed on the inner surface of the connected parts.
• When the force of the riveter reaches a certain value and the connection of the parts is strong enough, the remains of the elongated rod are broken off.

When working with a manual riveter, as a rule, several pressings of the lever are required to achieve the desired result. After the process is completed, one side of the joint will have the head of the rivet body, and the other will have the flattened end of the cylinder in the form of petals.

Removing rivets without drilling

Blind rivets, or POP rivets as they are also called, are a popular fastener for joining sheets of metal. The installation of these hardware is carried out with a special device, which allows you to quickly and reliably fix them in a pre-prepared through hole.

Unfortunately, there is no device that removes rivets of this type, and if it is necessary to separate sheets connected by rivets, they most often resort to drilling them out with a drill. This simple and effective method requires care and precision, and besides this, success can only be achieved with the right choice of tool.

The drill should not completely drill out the rivet and push it out of the hole - its task is to destroy the side that holds the body of the hardware in the design position.

But it is not always possible to use a drill. Sometimes it happens that this power tool or suitable accessories for it are not at hand. How to be in this case? Removing the rivet without drilling is possible and we will now tell you how to do it.

Removing the rivet using improvised tools

As we have already said, the basis for dismantling any POP rivet is to machine the hollow section of its head until it comes off the shank. This simple but very precise operation can be performed using a thin chisel or flathead screwdriver, as well as a hammer. The sequence of performing this work is as follows:

1. First of all, it is necessary to determine the thickness and material properties of the sheets connected by blind rivets. Knowing the parameters of the metal, you can accurately select tools and approximately calculate the maximum permissible force during dismantling. When working with very thin sheet material, our method can hardly be called optimal and can only be used at your own peril and risk.
2. To remove the rivet, place a chisel or the tip of a screwdriver between the side of its head and the sheet and, gently tapping it with a hammer, bend it. The thinner the material connected with fasteners, the more delicately you need to treat the work. You should also carefully consider the choice of tool - it should be thin enough so that it can be carefully driven under the side.
3. If the removal of the fixing part of the hardware was successful, you need to carefully remove the fastener from the through hole. For this purpose, it is best to use a thin screwdriver or a thin metal rod of suitable diameter. Your task in this case is simply to push the tail of the rivet out of the hole. Most often, this is possible without much effort, but sometimes you may need a hammer again - one or two blows on a screwdriver or rod aimed at the leg of the rivet will help push it out of its “home” place.

This method is good because it can be used even where connecting electrical tools is impossible - it is often used when performing work in the field.

Removing a rivet using a Dremel

A Dremel hand router or equivalent is ideal for removing the head of the rivet. One of the interchangeable types of equipment for these tools is a miniature cutting disc for sheet metal.

This tool can quickly and accurately cut the side of a blind rivet, but using such a blade requires some experience and a steady hand. If you compare this attachment for Dremel with a drill bit, it becomes obvious that it has greater contact with the metal surface.

Accordingly, it is easier to damage the material by cutting off the head of a POP fastener with a milling device than with a drill.

After the side of the head is cut, you need to push or knock the rivet out of the hole with a screwdriver or a rod, just as with manual dismantling.

Features of working with a manual riveter: device, how to use the riveter, choice of tool

In industrial enterprises, when manufacturing products, it is often necessary to perform operations to connect various elements and parts. This can be done using such a reliable method as connecting with rivets. Its help is resorted to in cases where structural elements cannot be welded. Compared to welding, this method has many advantages. A similar connection is created using a special tool for riveting rivets.

A riveter is a type of tool whose operation is based on the same principle as a pistol. It is used to connect structural elements and their parts with a thickness of no more than 1 cm.

When using such a mechanical gun, connections of parts are most often made from the inside. The manual riveter is a lever version of the gun, the design of which can be divided into two main elements:

• A lever system that provides the necessary force when connecting product elements.
• The spring mechanism necessary to pull the rivet inward.

Manufacturers produce two types of manual riveters - pull-out and threaded.

Exhaust type

This type of tool ensures the connection of parts due to the traction force through which the rivet is fixed. When the gun lever exerts force, the rivet rod begins to retract into its tubular part, pushing its rod head apart. On the outside, the rivet head is also flattened, and the result is a fairly strong connection of the parts.

Threaded riveters

Riveters of this type work on a similar principle with some exceptions. Here the ball is drawn into the working part due to the rotation of the thread in the tubular part of the rivet. In other words, the elements are connected by fixing the head by twisting the handle. This method of fixing parts elements is less common; it is mainly used to connect parts of small thickness.

As a rule, rivet tools are sold together with a set of attachments of various diameters.

Depending on the type of drive used, riveters can be classified into several main groups:

• pneumohydraulic;
• battery;
• electrical;
• mechanical (manual);
• pneumatic.

Mechanically driven devices are used most often in the domestic sphere. Manufacturers produce them in two versions: the first involves connecting parts using one hand, and the second - due to the force exerted by two hands.

The principle of connecting parts with one hand is the basis for the work of a manual riveter, known as an “accordion.”

Manual riveters can be purchased at various prices, which depend on several factors - type of drive, model, connection method and manufacturer. Devices from famous brands are more expensive than products from unknown manufacturers.

Battery, pneumohydraulic and electric modifications of the tool can also be considered expensive when compared with manual riveters. This can be explained by the use of a more complex structure in them. Most often, such devices are used in industrial production.

Blind rivet device

To learn how to work with a manual riveter, the master should, first of all, become familiar with the design of fastening elements, which are rivets designed to connect elements in a similar way .

This rivet looks like a fastener that contains two parts: a hollow tube in the form of a cylinder, at the end of which there is a head and a metal rod. The hollow cylinder is often called a rivet body or sleeve. Each riveter has a cylinder with its own special diameter, which corresponds to the size of the rivet fastener.

A hollow hole located in the cylinder passes through the entire body, including its head. The metal rod is made in the form of a regular nail with a rounded head. It is installed in a cylindrical hole, where it is subsequently retracted until the head stops using a latch.

To connect elements using a manual pull-out riveter, manufacturers produce threaded rivets, which have a thread inside the cylindrical body. Threaded threads are also present on the rod, which is placed in the cylinder by screwing it in.

To achieve a strong connection, a bolt or screw is usually used as fastener. This type of rivet also has another name - blind rivet. It differs from conventional exhaust in increased strength.

Various materials are used to create rivets used to connect elements with a blind riveter. The sleeves are made of copper, aluminum or steel alloys. The main requirement that the sleeve material must satisfy is not to lead to corrosion of the metal from which the connected elements are made. This means that during their contact there should not be a cathode-anode pair .

To make the rod, steel is used, the strength of which should be several times greater than the strength of the body. The rivet body cylinder may differ in both diameter and length. These are the main parameters of rivets that should be taken into account first when choosing. It is important that the diameter of the cylindrical body matches the hole for the fastener.

How to use a riveter is perhaps the most important question that interests the master. In order to create a reliable connection, during its execution you must adhere to the following algorithm of actions:

• Surface preparation.
• Marking and drilling holes.
• Installation of fasteners.

At the first stage, it is necessary to level the surfaces well so that the tightest contact between the parts can be ensured.

When starting to drill holes, you need to ensure that they are positioned strictly along the same line. To properly perform this operation, it is recommended that the surfaces be placed on a flat plane , for example, a wooden piece, to which they should be fixed. After this, they proceed to drawing the locations of future holes. Next, they begin to make holes, making sure that on each part they are located exactly in the designated places.

An important task is to ensure that the hole size matches the required parameters. To do this, it is recommended to take a drill of a slightly larger diameter. For example, if you are creating a 3.8mm hole, you would use a 4mm drill bit.

When the holes are ready, be sure to “try on” the prepared fasteners. If everything is done correctly, the head of the rivet will fit tightly to the surface in the area of ​​​​the edge of the hole and completely close it.

At the final stage, rivets are installed, adhering to the following order:

• First, the cylindrical body of the rivet must be placed in the hole made in the elements to be connected.
• Using a riveter, you need to grab the rod passing through the entire body, and it must be fixed with the lips or the riveting head of the tool directly at the base of the cylinder head.
• By exerting the necessary force on the rod, it must be pulled through the body of the rivet, simultaneously expanding it with the head and deforming the end of the cylinder. As a result, you should have a reverse wide part of the rivet on the inside of the elements being connected.
• Having selected the necessary force for the riveter, the parts are securely connected, after which all you have to do is break off the protruding parts of the elongated rod.

In most cases, when using a manual riveter, you have to press the lever several times to achieve the desired result. After connecting the elements, the head of the rivet body will be located on one side, and the flattened end of the cylinder, looking like a group of petals, will be located on the other.

Recommendations for choosing a tool

Today, stores offer many varieties of manual riveters, which can be purchased at a price of about 2-3 thousand rubles. To choose the most suitable model, you must first understand for what purpose you need the tool. If you decide to purchase it for frequent connection of different elements of parts, then we advise you to opt for a more expensive professional tool. For everyone else, a budget model will be enough, which will cost them about 150-500 rubles.

If you want the tool to serve you for a long time, you must not only know how to choose a manual riveter, but also be careful when using it. Otherwise, it will quickly break in your hands, even if it is an expensive professional tool from a well-known brand.

Price is one of the important factors to consider when choosing this device. But besides this, other characteristics are also important:

• Rivet material. To connect aluminum parts, you can buy any of the tools available in stores. If you have to fix steel parts, we advise you to opt for more powerful riveters.
• Ease of use. If you plan to use fasteners of different diameters and made of different materials for connections, then it makes sense to purchase a two-handed model. When choosing a tool, we advise you to pay attention to its head. It is desirable that it be rotating. Then you can easily make connections even in difficult areas. Before purchasing, it doesn’t hurt to find out whether the set of replacement attachments is included in the package. This is especially worth worrying about for those who plan to use different fasteners for connections.
• An important characteristic that must be taken into account when choosing a riveter is the presence of a waste container. It will be especially indispensable for those craftsmen who are going to build a fence on the territory or lay a roof.

Sometimes, due to design features, it is impossible to move the connection point. In this case, a special attachment, which is fixed on the side of the head, can help. When choosing the size and weight of the attachment, you need to take into account the thickness of the connection, as well as the material of the rivets. After this, you can begin riveting the free side.

It is optimal for the connecting metal to fill the entire space of the hole, and caps appear from each side, which should fix the parts. This method can be used not only to connect parts to each other, but also to seal holes in one sheet. This method is often used by craftsmen when they need to repair leaky containers.

When manufacturing metal structures, it is not always possible to connect parts by welding. In such cases, you have to resort to a more careful method of fixing the elements, which involves the use of rivets.

With its help, you can securely fix the connected elements together. However, you need to remember that ensuring the quality of the connection is not as easy as it might seem at first glance.

It depends not only on the riveter, which today manufacturers produce in various versions.

The rivet fastener itself also plays an important role in the process of fixing elements . How long the fastened parts will remain in this position depends on its correct choice.

Beginning craftsmen are required not only to choose the right rivets, but also to learn how parts should be connected using this fastener. Here it is very important to correctly select the required force for fixing the elements being connected, otherwise, when the product is loaded, these parts may become loose, as a result of which everything will have to be redone.

Rivet material | How to choose the right blind rivet material. — AIRIVET Company

Typically, blind rivets are made from the following materials:

• Uncoated steel
• Cink Steel
• Stainless steel A2 or A4
• ​Various aluminum alloys
• Monel (copper and nickel alloy)
• Copper
• Bronze
• Polyamide

Depending on the scope of application of the rivet, these materials can be combined with each other. For example, the rivet shank (core) may be made of galvanized steel, and the rivet itself may be made of aluminum. By the way, this is why this type of fastener is also called a combined rivet.

Selection of rivet material

The basic principle of selecting a rivet according to the material is that the material of the rivets matches as much as possible in its physical and mechanical properties with the material of the parts being connected. For example, excessive force on a stainless steel rivet can deform the surface of a softer material (plastic or aluminum).

Galvanic couple

We should not forget about corrosion. Galvanic corrosion occurs at the junction of two dissimilar metals in a corrosive environment (electrolyte). An electrolyte can be any liquid that conducts electric current, such as ordinary moisture in the air.

The degree of corrosion of the connection will depend on the concentration of the electrolyte, as well as on the difference in the electrochemical potentials of the metals being connected. If you are not sure about the correct choice of rivet material, use the table of electrochemical potentials (the so-called electrochemical series) to avoid galvanic corrosion.

The farther the materials being connected are spaced from each other in the table, the more intense the electrochemical corrosion will occur and the faster the connection will fail.

When dissimilar materials interact in a compound, the more electronegative material will be subject to corrosion (in our illustration, such material is located higher), since in a given galvanic pair it is a reducing agent, giving up its cations to the more positively charged material.

How to avoid galvanic corrosion?

Here are some simple tips to avoid galvanic corrosion in your riveted joint:

• Make sure that the rivet material and the material of the parts being joined are as close to each other as possible in the electrochemical potential table.
• Create a dielectric barrier between corrosive materials. This could be a layer of paint, a non-metallic washer or gasket.
• Select the rivet in such a way that it becomes the cathode in your connection, that is, the rivet material should be more electropositive. In practice, this means that if galvanic corrosion occurs in a joint, the anode (the surface of the materials being joined) will repair the cathode (rivet). This is the best-case scenario, given that, as a rule, the surface area of ​​the materials being joined is much larger than the area of ​​the rivet.
• If the rivet has a certain coating, it is the coating material that should be as close as possible to the material of the materials being connected in the table of electrochemical potentials.

Colored rivets

Some tasks involve the use of colored blind rivets. In this case, the rivets can be powder coated in a specific color according to the international RAL color matching system.

How to rivet a rivet: design, operating instructions, tips and tricks

Many items are created with various fasteners, the most common being the rivet. It breaks and you have to buy a new one. The replacement process is complex, and a number of relevant questions arise. How to rivet a rivet? It is difficult for anyone to cope with the problem manually; a special unit should be used. There are enough methods; they use convenient, simple, accessible ones as a basis.

How it works?

A riveter is needed when you have to repair clothes. It is difficult to do without it when fulfilling large orders (for example, in an atelier). The principle of operation of the unit is elementary. It is shaped like a pistol, and the base is a lever. There are two components to this. One retracts the fastener and is then flattened. As a result, the two parts are fixed, and their thickness can reach up to 10 millimeters.

To expand the range of applications, the kit includes special attachments that allow you to work with different rivets. If something is missing, then it is quite possible to purchase additionally. For personal use, a large arsenal is not required. Before setting a rivet, you need to understand how the device works.

Often it is quite possible to do without a tool, although the quality will be lower. The sales network sells various types of devices that differ in their characteristics, purpose, and operating principle. There are complex mechanisms. They are more expensive and are not necessary for personal use. There are options that are being rolled out. They are convenient to use in hard-to-reach places. The riveting procedure itself is quick and easy. You don’t need to make any special effort, reviews say.

Hand tools

Before you rivet the rivet correctly, you will have to understand the entire range of products offered. Most often, there are two types of riveters on counters: manual and pull-out. Their operating principle is not the same:

• Exhaust. The basis is traction, due to which fixation occurs. To do this, the element ends up in the device; with simple squeezing and squeezing, riveting occurs. The fastener itself has a special ball that is flattened. Without it, fixation will not occur even with manual influence.
• What does a lever mechanism do? The operating principle is simple, which is why this manual unit has a low price. The action process is similar, but the ball is fixed in the tube when the handle starts to move. It is used infrequently (for things that are too thin). The choice is made by the buyer, assessing the complexity of the work and the activity of use.

Mechanism and technology of riveting

Devices are divided into pneumatic, mechanical, pneumohydraulic. Each type has its own operating principle and scope of application. If we summarize all the procedures, then using such a unit will not be difficult. You have to do some basic steps:

• Prepare the components. They must match each other in diameter.
• After which they are placed on a tree and secured. Mark holes for fastening. It is important to be precise so that subsequent steps are error-free.
• Next, using a drill, a hole of the required diameter is made. This step is not always necessary.
• Afterwards, the fasteners are fixed in the sharpener.
• A riveter is placed on the upper part.
• Only after this is a sharp, strong compression done. It happens that nothing works the first time. Then the process repeats.

The procedure seems simple, but many people have problems. What to do if you don’t have such a device at hand? How to rivet a threaded rivet without using special tools? It is quite possible to cope with this, but it is worth taking useful recommendations as a basis.

How to work manually?

A rivet is the most basic way of fastening two parts. There is evidence about it even in ancient times. Today they sell a wide variety of types, the assortment is off the charts. To highlight the strength, pay attention to the material. There are several types:

• Aluminum.
• Copper.
• Brass.
• Steel.
• Made of stainless steel.

The first three most often act as decorative finishes, but the second two are quite suitable for containment. But before riveting the fastening element, two components from the same material are selected on the clothing.

The simplest option is the overlap of two elements. When the fabric of a garment (for example, a fastener) overlaps another. This method is known to many and is often used in the studio. When making clothes, you will certainly have to use special devices to perform several procedures. But if a part breaks, you can return it to service manually at home.

Why does fastener breakage occur? There are many reasons for this - the fabric was pulled sharply to the right, to the left, impact, load, etc. Before riveting the rivet on the clothing, you will have to remove the deformed part, but carefully, without damaging the fabric. To do this, use any sharp object - a knife or scissors.

However, you need to know that mortgage heads have different shapes. They are mostly semicircular. Having removed the broken structure, you will have to select a new one that matches in size, diameter, and density. It is not always possible to purchase a completely identical one. It consists of two parts - the hole and the head itself with the base.

Nuances

This button has two components. If you have no work experience, you will have to prepare for incorrect fixation, so it is better to have several components. Every action is thought through, thereby eliminating repeated processes and the purchase of a new part. The basic principles are accuracy, precision, and the presence of the necessary auxiliary components. When failure occurs, it will lead to damage to the clothes themselves.

Tools

What do you need:

• Button set.
• Spoke.
• Pliers, a hammer or something similar to secure the button itself.
• Soft plastic.
• Scissors.
• Rubber.

Ticks

Specialized stores sell pliers that are convenient for making clamps; they look like pliers. It is better to make sure that there is a suitable attachment for riveting. Before this, a puncture is made at the fixation site, but a little less than is necessary for the part itself. This is done with a knitting needle or a blade - they are prepared in advance.

The front part fixes the button. Everything is done smoothly so that after fastening there is no shift. A plastic figure is mounted for easy mounting. It is made with two holes (top and bottom). After this, the riveting is carefully placed into the created structure. When using forceps, use maximum force. There should be no fear, otherwise nothing will come of it.

What's next?

Place the pliers as expected, after which you press until you hear a peculiar click. Simple pliers are suitable - a hammer, iron tongs. To prevent tearing of the fabric, a rubber gasket is installed. You should not exclude such additional gaskets, otherwise you will have to redo the work again. The process of sewing and repair will not be complete without such procedures.

Now it’s clear how to rivet a rivet without a riveter. If we talk about clothes, then a rivet is not only fashionable, but also practical. Although breakdowns occur frequently, for this reason you should know the instructions for performing the work. At the same time, not every person implements a project without losses - mistakes are not excluded.

Sometimes it is impossible to rivet a garment without a riveter. In such a situation, they turn to professional studio workers. Although the masters say that with the help of a special tool it will be possible to do the required process correctly. With it you will no longer need to use a lot of effort and technical knowledge. Finding the entire set of required tools for the job is easy.

How to rivet a blind rivet without a riveter

Rivets are a fairly common type of permanent fastener. Rivets are used not only in industry or production, but also in everyday life. Today, at any construction market in the tool section you can find a riveter. This is a specialized tool for installing blind rivets (the most common type).

On the website https://rskcorp.ru/katalog-produktsii/zaklepki it is not difficult to buy rivets in bulk from the manufacturer from the RosKrepezh plant. The batch can literally be of any size. If you believe that rivets will not provide sufficient reliability of installation, this article will provide facts in favor of the opposite.

Principles for installing blind rivets using a rivet gun

The above tool has several technical features:

• several nozzles for rivets of various diameters;
• wrench for changing attachments;
• handle lock.

To use a rivet tool, you must first drill holes whose diameter exactly matches the diameter of the selected rivet.

Next, the long part of the rivet is installed inside the rivet. Both surfaces to be joined are squeezed as tightly as possible with your free hand. To avoid injury, it is recommended to use pliers or any other similar tool.

All that now remains for the user of the riveter to do is to sharply and forcefully connect the two handles together (squeeze them towards each other). Thanks to this movement, the rivet unravels inside the hole and tightly connects the two surfaces.

In this case, the riveter will “bite off” the excess from the exhaust part.

Problems that may arise with the riveter

After the exhaust part is removed with the tool, it should fall out through the hole. However, after some time of constant use, you may encounter the fact that the exhaust part will get stuck inside the tool.

Moreover, it will be impossible to get it out of there either with pliers or with several direct blows. The reason lies in the sponges that compress the exhaust part.

If blocking occurs, most likely the jaws inside the tool are misaligned. You will have to completely disassemble the tool and install the jaws in the correct position. After this procedure, the functionality of the equipment will be completely restored.

In the video, a home craftsman clearly demonstrates how to quickly and easily fix the problem of “biting” the rivet part:

We all know what a great thing threaded rivets are.

In some cases there is no alternative to them.
Until one certain time, I somehow managed without them. But one fine day a wonderful car came to me and needed window protection installed. Like this:

Then I started working on collective farms, and in the end I ended up with a device that was not very presentable in appearance, but very functional, and with its help I have installed more than a dozen rivets.
The base is an M6 bolt, strength 8.8

This is what it looks like assembled, with the rivet installed

Main parts: M6 bolt. A piece of M12 bolt. More precisely, there was no bolt, no stud. A nut is welded on one side, turning it into a bolt. The stud is drilled through D=6.5mm.

Then comes the nut from the UAZ stepladder. Strong. Next is the support bearing, the dimensions are not important. Next is a washer with a fitting from the brake pipe. It doesn't matter either. I installed what was there.

How to rivet a metal rivet?

Welding is, of course, good, but it cannot be used everywhere. In this case, riveting is used - this is a mechanical connection of parts using special fasteners. These fasteners are called rivets; they are made from different materials and come in different types.

What is riveting

The mechanical connection of parts using a series of rivets is called riveting, and the connection itself is called a riveted seam. It is used where it is inconvenient to weld parts or where non-weldable materials are joined.

Not only metals are riveted, but also parts in clothing, accessories, etc. are connected in this way. But there it is more of a finishing touch than a loaded connection. So next we will talk about riveting in construction or home improvement.

In principle, you can use a screw connection instead of riveting, but bolts and nuts are more expensive, and their installation takes longer.

This is what a rivet joint looks like

If we talk about installing fences made of corrugated sheets, rivets are more reliable, since they can only be removed by drilling out the fasteners. When installing screws or self-tapping screws, they can be unscrewed and both metal and hardware can be removed.

In some cases, riveting is more convenient when installing a roof made of corrugated sheets or metal tiles. On the roof, installing screw connections is problematic and time consuming.

But rivets, and with a good tool, can be done in an hour or even less.

Most common use in private households

How are parts connected using rivets? The rivet is installed in the prepared through hole. It has a head that rests on the material and the rod. During the riveting process, the end of the rod is flattened, changing shape under the influence of force. Therefore, ductile metals are used for these hardware.

Types of rivet seams

If we talk about the method of joining sheets, then riveted seams can be overlapped (one sheet overlaps another) and end-to-end. Joint seams can have one or two overlays. With overlays they are more reliable and are used in critical and loaded places.

Types of rivet seams: overlapped and butted with overlays

According to the location of the rivets:

They can be located opposite each other or in a checkerboard pattern. Seams can be strong, tight (sealed) or durable-tight. Dense ones are made using elastic gaskets placed between the parts to be connected. Durable and dense ones are used mainly in boilers. Now they are more often replaced by welding.

Types of rivets

What is a rivet? It is a cylindrical rod of ductile metal (may or may not be hollow) with a shaped head at one end. This head is called a mortgage. During the installation process, due to the flattening of the metal of the rod on the second side, a second head is formed. It is called closing (closing).

There may be composite rivets (such as the popular blind or screw rivets), which consist of a body and a shank. But this does not change the essence: the embedded head rests on the material, and at the other end, due to the plasticity of the metal, a second head is formed. It is simply formed due to the fact that the rod is extended and the expanded part crushes the second part.

Types of cores and embedded heads

Rivets differ in the shape of the head and the shank. According to the type of rod they are:

• with a solid rod (high load capacity, but difficult to install);
• semi-hollow (part of the rod near the embedded head is solid, part is hollow);
• hollow (the head and rod have a cylindrical solid hole, they are easily riveted, but cannot withstand high loads).

Types of rivets by type of rod and head

Rivets have the following types of heads (pictured above):

• Semicircular (high and low). Sometimes also called spherical. The most reliable, create a strong seam.
• Cylindrical and conical (flat). Used if the connection is in an aggressive environment.
• Secret and semi-secret. Installed when fasteners should not protrude above the surface. The most unreliable connection, used only when necessary.

Different rivets can be installed nearby

Each type of embedded head is found with each type of core. They are selected depending on the planned load. For maximum loads, hardware with a solid rod and a semicircular head is needed. Hollow seams can also be used for seams that are not too loaded, but they do not provide tightness. If such a characteristic is important, then semi-hollow ones are installed.

Types of rivets

Despite the fact that welding has become accessible even to a layman, riveting does not lose popularity. After all, not all metals can be welded, and the welded seam is susceptible to corrosion. Therefore, new varieties of rivets are constantly appearing, so there is definitely no complete list. Let's look at the main and more popular ones.

• Classic or ordinary. Universal, used for all types of seams. They can be distinguished externally - they resemble fungi.
• Semi-tubular (the rod is half hollow). They require less effort during installation, but their strength is low. Used in connections with low mechanical load.

Classic and threaded rivets

Nut and rivet rivets

These are the main types of rivets that are used in construction, mechanical engineering and other fields. Each species has its own subspecies that differ in nuances.

Blind rivets

Let's say a few words separately about blind rivets. They are used for fastening corrugated sheets and metal tiles. These are the ones you most often encounter when arranging a site.

The blind rivet consists of a tubular body and a solid rod inserted inside. They are called composite because they have two independent parts.

Also, this fastener is reinforced - after installation, part of the rod remains inside, which increases the strength of the connection.

How does a blind rivet work?

The length of the blind rivet body must be greater than the thickness of the parts being connected. It is inserted into a hole made in advance, after which the riveter grabs the rod and pulls it through the hollow body.

At the far end of the rod there is a ball that forms the closing head from the flared edge of the body.

The excess rod is removed with a tool, but some of it remains inside, which makes this connection quite strong.

As is clear from the description, it is important to choose the correct rivet size. Too short will not allow a normal bead to form, which will weaken the connection. A body that is too long will give a lot of play, which is also not good. So when selecting this type of fastener, carefully look at the recommended thickness. Ideally, your connection is in the middle of the range.

How to properly install a rivet nut

In this review we will talk about how to properly install a rivet nut. But first, let's figure out what they are and what they are needed for.

Also, probably, many of you will be interested in learning how to choose the right rivet nut for specific types of work. Well, let's talk about everything in order.

A rivet nut is a type of fastener that is designed for installation in products made of thin sheet metal in order to form a threaded connection in them.

It is impossible to cut a thread in a thin plate with a regular tap, so a rivet nut is an ideal solution for workpieces and products made of thin sheet metals

Rivet nuts differ in their shape. They come in cylindrical, hexagonal or half-hexagonal shapes, cylindrical with grooves and even rubber.

What types of rivet nuts are there?

The simplest rivet nut is a regular cylindrical rivet with a flat flange. Its peculiarity is that it has relatively little resistance to turning.

In other words, when installed in a material, since it does not have corrugation, such a rivet-nut can easily be rotated inside the hole itself.

In order for the rivet to hold more firmly after installation in the material, it is corrugated.

After installing such a rivet nut, thanks to the corrugation, it resists turning in the material much better.

If you need a rivet nut that will provide maximum resistance to turning in the hole, then choose a hexagonal fastener.

There is also a special neoprene rivet nut, which is a collapsible element.

Conventional steel rivets, unlike neoprene ones, cannot be removed after installation - they are permanent fasteners.

Which rivet nut to choose

Now let's figure out which rivet to choose for a particular material.

Just as in the case of blind rivets, for different types of material it is necessary to select rivet nuts from a similar material.

For a steel plate you need to use a steel rivet, for a stainless plate you need to use a stainless steel rivet, for an aluminum plate you need to use an aluminum rivet.

By choosing the right size and material of the rivet nut, you can select the required load on your fastening joints.

Accordingly, in order to select the correct size and material of the rivet nut, you need to know the load on your connection and the fastener that will be installed.

Features of installation of a rivet-nut

In order to install a rivet nut into a metal plate, a hole must be made in the workpiece itself.

Depending on the type of rivet nut, the hole may be different. For example, for a regular cylindrical rivet, a cylindrical hole is suitable.

For a hex rivet, you need to make a hex hole. However, such a hole can only be made with a special tool or on a laser machine.

Therefore, hex rivets are usually used in industries where it is possible to make a hexagonal hole in parts and workpieces.

A hole of exactly this shape is necessary so that the rivet is maximally protected from turning in the material.

A very important point is the choice of drill in order to make the correct diameter of the hole for the rivet nut.

Each rivet has a certain outer diameter, and the drill must be 0.1 mm larger than this diameter.

You can also check the manufacturer’s catalog to be sure, because this indicator can sometimes differ slightly.

How to install a rivet nut into a part

The first step is to drill a hole of the required diameter in the workpiece itself (let it be a steel plate).

To do this, you must first measure the outer diameter of the rivet nut. For example, it is 5.9 mm. Then you need to take a metal drill with a diameter of 6 mm.

Before installing a rivet into a part, it is advisable to make a couple of rivets in a workpiece of the same thickness.

This is necessary in order to correctly configure the rivet gun, namely, it will be necessary to adjust the stroke of the rivet gun and the projection of the stud.

We screw on the rivet (note that the pin should stick out from it literally a few millimeters), then press it with the nozzle, and fix the nozzle.

Next, we install the rivet-nut into the hole in the steel plate, press the rivet tightly to the material with the flange and strictly at an angle of 90 degrees, without deviating horizontally or vertically, we begin installing the rivet.

Rivets for riveter sizes table

Welding is, of course, good, but it cannot be used everywhere. In this case, riveting is used - this is a mechanical connection of parts using special fasteners. These fasteners are called rivets; they are made from different materials and come in different types.

How to rivet a rivet correctly

Welding is, of course, good, but it cannot be used everywhere. In this case, riveting is used - this is a mechanical connection of parts using special fasteners. These fasteners are called rivets; they are made from different materials and come in different types.

Threaded rivets

In the past, the most common fastening elements were rivets (especially in the mid-20th century). To date, they have been significantly supplanted, but still remain relevant in some cases. Next, we consider one of the types of fastening elements - threaded rivets: their general features, classification, areas and technology of application.

Peculiarities

Rivets are fasteners in the form of a sleeve or rod with a rivet head at one end and a head that closes during the rivet process at the other. Threaded rivets differ from blind rivets by the presence of threads.

That is, they are hexagonal or cylindrical bushings with a supporting flange at the top and threads at the bottom. The upper part is made in the form of a thin-walled tube without threads and often has a longitudinal external notch. During installation it becomes deformed.

The vertical notch on the top ensures uniform deformation and prevents tearing of the material.

The advantages of threaded rivets include:

• ease of use;
• strong bonding of elements made of fragile and thin materials such as sheet metal without deformation;
• the possibility of one-sided fixation if the total thickness of the parts being connected exceeds the length of the fastening element without loss of strength;
• maintaining the strength of the connection over time;
• mechanical and chemical non-aggressiveness;
• maintaining the integrity of the surface and paintwork;
• the ability to connect elements from different materials;
• absence of mechanical stress in the structure;
• Possibility of dismantling and reinstallation.

Despite the fact that nowadays, in most cases, instead of rivets, welded or glued joints are used, the fasteners under consideration have a number of advantages in comparison with them, which determine their indispensability in some assemblies.

First, threaded rivets can withstand heat. Secondly, they do not cause structural changes in elements during installation, unlike welding, which is especially important when connecting parts made of different materials, the behavior of which can be unpredictable.

Third, threaded rivets ensure mobility is maintained.

However, these fasteners have a number of disadvantages:

• installation is complicated by the need to pre-make holes;
• most threaded rivets do not ensure tight seams;
• installation is associated with a high noise level.

Application

Threaded rivets are suitable for any connection, but are most appropriate when there is no access to the back side after assembly is complete. They are usually used for joining sheet materials. Threaded rivets are much simpler than other types of connections: they are easier to use than welding or cutting threads. Some of them provide the possibility of additional fastening using screws or bolts.

The scope of use is largely determined by the type of threaded rivets. Thus, elements made of non-ferrous metals are in demand, first of all, for decoration due to their good aesthetic properties.

Stainless and steel rivets are used for assemblies designed for difficult operating conditions, due to the fact that they provide increased strength of connections and are resistant to corrosion. Threaded nut rivets are suitable in conditions of limited space and when there is no access to the reverse side of the assembly.

Hexagonal models eliminate the possibility of turning. In addition, as noted, there are options with additional properties designed for specific operating conditions.

According to the installation principle, threaded rivets are similar to blind rivets. The work includes several stages.

• The most extensive is the preparatory stage. The main factors for creating a riveted joint are the type of material of the parts and the type and diameter of the thread of the hinged element. Based on this, a riveting is selected (with internal or external thread, diameter, etc.). Based on its size, choose a drill 0.1 mm larger to make it easier to place it in the hole.
• First of all, you need to create a hole at the connection point. Typically a drill is used for this. Hexagonal holes can be made with punches, but they are only suitable for thin material. If the material is thicker than the fastener, the hole should be made slightly deeper than the length of the rivet, but a through hole is not required.
• Next, based on the thread, the rivet rod is selected and the threaded rivet is screwed onto it.
• The tool is mounted in the hole.
• The fastener is compressed by bringing the handles together or rotating the bolt until its rear part is deformed. However, do not use excessive force to avoid stripping the thread.
• The rod is unscrewed from the fastening element and the position of the threaded rivet is checked.

It should be noted that the quality of the seam is determined, among other things, by the row. Often they use a multi-row arrangement of rivets in a chain or checkerboard pattern.

When installing threaded rivets with your own hands, a riveter with a manual, hydraulic or pneumatic drive is used as a tool, as well as a specialized press and an automatic system.
The durability of the connection is largely determined by the outer diameter of the fastener.

There is a direct relationship between these factors. That is, the larger the diameter, the higher the strength of the connection and its resistance to loads. In addition, strength is determined by such parameters of threaded rivets as wall thickness and lack of corrugation.

However, these characteristics also affect the complexity and ease of operation.

The required length of the threaded rivet is determined based on the thickness of the elements being connected. However, it must be taken into account that such fasteners are designed for sheets with a thickness of 0.3-6 mm. So, for nodes with a thickness of 1 mm it is recommended to use models M3, for 1-3 mm - M6 or M8, for more than 4 mm - M10.

The material determines the parameters and, therefore, the scope of application of threaded rivets. Thus, carbon steel is used to produce universal options designed for standard connections. To ensure corrosion resistance, products made from this material are often coated with zinc.

Stainless steel provides fasteners with resistance to heat and moisture (that is, anti-corrosion). In addition, these options are more durable. Aluminum products are characterized by anti-corrosion properties and low weight. Bronze threaded rivets are characterized by minimal sparking.

The last two options are used for fastening parts made of the same materials. They are not designed for heavy loads.

Models with standard flanges are used for conventional threaded connections. Fasteners with a reduced flange are designed to achieve the smallest gap between the elements being connected. Options with a hidden side are suitable for the same purpose.

However, they require preliminary countersinking of the holes. In addition, models with a hidden side are relevant for cases of one-sided installation, when the total thickness of the parts to be connected exceeds the length of the fastening element.

Consequently, the threaded rivet cannot provide full compression, and fixation is ensured by its expansion in the hole.

If a mechanical riveter is used, significant efforts will be required due to the large resistance of the fasteners in question. Pneumatic tools are much easier to use, but they are quite expensive.

To date, rivets have largely been replaced by welded and bolted connections. Nevertheless, they remain relevant in the aviation and shipbuilding sectors, assembling furniture and window frames, installing ventilation systems, etc. In terms of strength and reliability, riveted joints are similar to welded ones.

In addition, threaded rivets are relevant in cases where it is necessary to install on the surface of a part when it is not possible to cut threads due to the small thickness or when there is no access from the reverse side to use a nut.
