How to rivet rivet - automatic and manual methods for different materials. Removing rivets - riveting how to remove rivets from metal

Rivet is an excellent and durable type of fastener. But unlike bolts, nuts, studs and screws, you will not delete it without damaging. The bolt can be unscrewed with keys or screwdriver, after which it can be reused. Torn rivet will have to throw out. The question arises: "How to split rivets if there is no riveter in arsenal?"

Essence rivet

Rivet - disposable fasteners. But he is also the cheapest. If the device is done forever and does not imply disassemble parts in the future, these parts can be riveted with rivets. Keep they will be as firmly as the screws, but will be even more reliable. The screw over time can get out, the rivet will not disappear itself, as it is impossible to split it without the help of special tools.

Rivets in construction and mechanical engineering

There are many alone have the form of a single part - the sleeve, which is inserted into the hole and with the help of a special riveter expand the edges of the sleeve on the other side of the parts connected and pressed (flatten). Such rivets are the most common, cheap and reliable. They are used mainly in construction and mechanical engineering. How to split rivets building species?

Dismantling construction rivet

This action is dismantling as such is difficult to call. This is a removal. To remove the rivet, you will need a regular riveter with which it was installed. But since it is not at hand, it is worth dealing with how to split the rivet without a riveter.

Rivets, who have a hat or a curved part sticking over the plane of gluing parts, you can try to rip the sharp chisel and the hammer:

Install the cutting part of the chisel exactly under the Hat (or curved part).
Hit the chisel with a hammer. To disrupt some large rivets, you may need several shots.
When a hat (or curved part) is tearned, it remains only to remove the rivet out of the hole. This can be done by pushing it with a nail or other subtle subject (for example, a screwdriver).

But more often than hats and curved parts will not be careful because they are like in the body of fastened parts. Under the Hats and Expanding Parts in the details, special grooves are drilled at the plant, and then rivets are sitting in a metal like gloves. How to split rivets in such a "wisdom" case?

Here, the revenue will come a screwdriver (or drill) with a rivet-selected metal drilling with a rivet diameter. Act as follows:

Core Make a seat on a rivet hat, so that the drill does not walk, although some are accustomed to do without sneakers.
Install the screwdriver drill on the hat and drill the outbreak of rivets.
When the drill passes through, the remnants of the cap and the extended part are falling out by themselves.

Rivets on clothes

But rivets are used in the manufacture of various types of clothing models. Their use began in the 19th century, when when sewing pants from rude cans, which will be referred to jeans in the future, one of the masters noticed that if the seams at the beginning brighten with a rivet, he would definitely disappear and does not break.

Here the rivets go to move, which is more suitable for the "buttons" name. Unlike ordinary, they consist of two parts - internal and outdoor. Everything is kept through the head of one element enters the cavity of the other. Then under the pressing of the rivet, the head of the inner element is flattened (expanding) inside the cavity of the outer element, and such a "super-point" is no longer breaking, no matter how straining. Rather breaks the fabric. How to split rivets such varieties?

Remove rivets from clothes

This is done in two ways. One - with the help of booths, the other is a knife and pairs of the passage. The choice of methods depends on how your rivet is alpha (internal) or beta (outdoor). The corners and edges of the stitch are mainly rushed by the varieties of alpha, which are otherwise called chief. Beta is used in cases of buttons with clothing. One part there is alpha, and Beta is sticking to it. Despite the fact that the material of such rivets hold perfectly, they are afraid of mechanical exposure.

How to split alpha rivets with a knife and two pliers?

It is done.

And how to split the beta rivet on clothes? It's still easier. The procedure for action is:

Exhaust rivets are popular fasteners widely used to connect sheet metal. This fastener is installed very simply, but its disadvantage is that the riveting connection is intimidate and when installing, you need to show maximum attentiveness when determining the installation site of the metric. But how to be if the error and the exhaust rivet are allowed to delete?

We use drill

Rivet connecting metal sheets can also be removed easily as installed. In order to remove the hardware, the electric drill and metal drill will need. The diameter of the drill snap should be slightly larger than the diameter of the riveting rod, but at the same time less than the size of the head. Getting Started to dismantle, you need to know that the ultimate goal of drilling is the destruction of the head holding fasteners in the metal, and not complete driving driving. In the event that the diameter of the rod product is unknown, it is necessary to make measurements of the outer side and, repulscing from this parameter, find the desired size in the manufacturer catalog of hardware.

When drilling a rivet, the number of revolutions of the cartridge drill is minimized - this will allow you to perform work as high quality and fast. The end of the drill is set to the recess formed by the sides in the center of the head, and the tool itself is positioned so that its axis is strictly perpendicular to the connected rivet material. It is necessary to start drilling very carefully so that the drill does not slip and caused damage to the material. In some cases, especially when it comes to a miniature fastener, it is recommended to use a manual drill.

When the drill "will pass" the exhaust rivet head, the connection will collapse. In some cases, when the rod of methiza does not fall out, it is recommended to use the hammer and punch suitable size. In order to knock out a sheet metal rod, usually 1-2 accurate blows of medium power. If the work is neat, then the metal around the connection site will not receive damage. After the rod is removed from the opening, you can go to the next rivet.

The method described above is good in cases if you want to perform the most accurately as possible, and at hand there is a drill and a drill set. But sometimes, if the aesthetic component is not too important or when there are no power tools at hand, you can use in another way, for example, knocking down the head of the rivet with a plumbing chisel.

Exhaust rivets are made of non-ferrous metal alloys or soft steel, so it's not difficult to "cut down" her head chisel. To remove fasteners, the cutting edge of the tool is inserted under the edge of the heads, and then apply a hammer blows until the upper part of the methome is removed. Rivet residues can be knocked out the corresponding spacer. It is worth saying that this method is not gentle for the elements connected and, if the metal around the rivet was painted, the coating will be inevitably damaged.

In the past few years in building stores, you can find such a tool like a split nozzle. This is a simple I. effective fit To remove rivets, which is equipped with an electric drill. The principle of working with the nozzle is the same as with a conventional drill, but the drill can be faster and more accurate. The device allows you to accurately install the drill on the center of the head and drill on a strictly limited depth setting sufficient to remove the upper part of the methome. Unfortunately, this device is not universal and for fasteners different sizes We will have to use replaceable accessories of different diameters. The acquisition of the nozzle makes sense only when a large amount of dismantling has to be performed or if the work is performed in extreme conditions. Often, drills with such a snap can be seen in the arsenal of roofers working at height - work with the nozzle allows you to remove hardware using one hand.

In many industrial products, rivets are used, as a way to securely and quickly bore a node, which will not be able to understand. Often it is so connected by thin sheet metal. If you have a need to remove a riveting and not damage the surface of the product, then I will offer three things available method To achieve the desired result.

Driving rivets

The easiest I. safe method, From the point of view of mechanical impact, this drill is drilled.

We take a screwdriver or drill. Install the drill the desired diameter. And drill through a riveting.

We pass through.

This method does not damage the connected metals if the drill is selected correctly. Although it is pretty specific and will not suit you if your rivets are semi-rounded hat.

Cutting Bulgarian

This is the fastest and at the same time the most traumatic way to remove rivets. Therefore, if you are insecurely owning such a tool as an ush (Bulgarian), I sincerely do not recommend using it.

We need:

Bulgarian.
Screwdriver.

ESM spill heads from all rivets installed.

And knock them out a screwdriver.

That's all the trick.

In this method, simply damage the surface of the product and break the disk itself, since cutting is at an angle. And one incorrect movement can spoil everything. Mandatory use protection tools.

Sut off the hat rivets chisel or screwdriver

Now the way is called classic. It uses the majority of both professionals and beginners. It does not require special equipment, electricity, preparation. The most accessible and at the same time the slowest cutting method of rivets.
It will take:

A hammer.
Screwdriver or chisel. It all depends on the diameter of the rivet.

If the size is small, we take a screwdriver, put at the angle and blows of the hammer cut off the hat.

If the rivet is big, then it is better to apply chisel. We act as well as a screwdriver.

We also knock out a screwdriver.

This method can be used when rivets are a bit: one, two or three. Or when there is nothing of the above equipment in the first two ways.
If the rivet connections are very much, it is better to use a more mechanized removal method.
Be careful when working with metals. Also share in the comments with your suggestions, everything will be interested.

The nipper is a disposable fastening element intended for fastening 2 or more details. To install this fastener, use a creek. How to remove the rivet will have to proceed from the presence of remedies, because there is no universal tool. In addition, the selection of metal structures is made in accordance with the technical characteristics.

Aluminum, copper, steel differ in hardness, in different degrees they are subject to diffusion, oxidation rate and other physicochemical processes. The only way that can be called almost universal is drilling. This process can be carried out in 3 ways that in most cases it depends on how much the metal fastening is affected with the fastened elements.

Way to remove exhaust ripple

The exhaust rush is removed somewhat easier. Conducting it to dismantle it is necessary to remove the ring formed when fixing. If it is possible, when compressing the material of the structure, insert the sheet of the saw on the metal, the mount can be cut off, and remove the stud, pulling out for the rod. If there is no possibility to cut or cut off, there is always a chance to remove the fastening in the first way - drill.

You can only remove the secret mount, and the exhaust heads can be knocked down with a hammer, if the strength of the material fastened is greater than that of the fastening itself. Provided that using this way of dismantling, no confidence of 100% security for own hands and external view Material, it is better to refuse it.

To date, the most reliable version of fastening connections is durable, and, having special tools in your hands, you can not think about the question, how to rivet rivets. Next, we will tell you exactly how similar fasteners are performed.

What is this fastener? Initially, historically, it is a metal rod, less often - plate. Always with a mortgage head on one side (a hat that limits the movement of the element in the hole) and closes on the other end.For the first time was used to make armor, such as lats and chain rails, as well as for connecting some elements of cold and early firearms. If the mortgage head is originally available, then the closing occurs due to the precipitation process (digging) or with the help of a special tool due to the deformation of the exhaust rod. It is logical that the sediment is applied to cast or stamped, all-metal elements, and the deformation of the rod is possible only when using hollow (tubular) exhaust rivets. There are also explosive and cut options.

A variety of rivets

So, we know that the fasteners under consideration are inconsectable, which ensures often high reliability. But the strength of the compound depends primarily on the material, so we first consider the varieties of rivets precisely on this characteristic. The most common - aluminum fasteners, in many production processesAlso in a number of crafts use copper and brass rods. All these materials do not have a high degree of reliability and are suitable only where there are no large loads, for fastening decorative parts. Among other things, there are steel rivets, including from a stainless steel, they provide a sufficiently strong connection and are suitable even for assembling bearing structures and mechanical engineering.

Very important when installing metal details Use rivets from the same material as connected items.

Before using rivets, you need to know how to rivet about or other details. There are many ways to connect, but they are divided, as a rule, on 3 types. Durable fasteners are used exclusively where certain loads are present. Hermetic, as it is clear from the title, is needed to ensure tightness in the places of connecting sheets or any details. And finally, firmly sealed perform both functions. It should be noted that for the second type, that is, for sealed rivets, mortgage heads are made reinforced.

Exhaust rivets

The most common way to connect is the mustache, while it is applied not only to, but also to the details of a complex form. This option is also called alone. Under the influence of multidirectional loads, for example, with stretching, such seam can be easily deformed. The connection is more durable, using one or two (on both sides of the seam) of the lining, but this option, also called multi-precipitated, strongly dries the design and leads to more material consumption. Setting rivets when fasteners can be chain or chess, the second is more reliable, but very laborious.

Mortgage heads are of a variety of forms. The most commonly used is semicircular and counted. The first completely overlap the hole like a screw cap, and for the second channel is collapsed so that the head of an inverted cut cone is fully fit in the well. In the second case, the surface of the part remains smooth, because the riveting takes place, and the destruction of such rivets becomes difficult. Also there are semi-employed form factors (with a small rounded convexity), flat, flat-conical, conical and oval.

The most commonly used exhaust riveting elements are used, which are especially convenient if it is necessary to attach the part to the surface, the opposite side of which is not available. They are a rolling tube on one of the ends (analogue of a mortgage head), in the channel of which runs the rod with a hat on the even end of the riveting. From the collapsed side, most part of the rod is extended, with which the clutch of the tool is gripping, for subsequent stretching through the tube. Its smooth end is frozen a rod cap and forms a closing head.

Rivets for metal

However, it should be borne in mind that when connecting two parts, its channel is expanding, so the edges of the holes must be durable, non-exposed deformation. Therefore, for fastening the plates of a sufficiently soft material, whether plastic or aluminum, mortgage sleeves from steel or washers from both sides of the connecting parts should be applied. The same applies to the compounds that must be movable, hinged, they are also applicable in a complex with sleeve beds, and the length of them should exceed the total thickness of the fastened plates.

Unlike exhaust, ordinary cast or stamped riveting elements must be installed using the efforts defined to the short-circuit end. This can be pressing or targeted blows for flattening the end of the rod outlet. The second option is most reminiscent of the forging, especially since it is performed with a cold or hot way. If the thickness of the riveting does not exceed 1 centimeter, you can use the cold window of the closing head. If the diameter is more than 10 millimeters, then the fastening element is needed to facilitate the unloading of its end.

Tool for rivet

As a rule, before sprinkling a hot rivet, it is heated in mountain, after which they are installed in a hole and several strong blows make a flat closing cap. At the same time there should be an odor with a hole under the mortgage head. For a cold method, a special tool is applied - a cross-rounded mouse, with which a smooth hemisphere is formed by deformation of the end of the end of the removal. The attack with ordinary hammer gives the same result if you beat the end, directing the blows slightly casually, from the center to the edges, but such a head will be less neat.

As we said, the type of connection under consideration is notionable, however, if it is still necessary to disassemble the design, the details of which are glued together, you can use several different methods. The most common, which is usually applied to exhaust, explosive and cutting types of fasteners, as well as where the hidden heads take place - drill. For this, the drill corresponding to the estimated or precisely known diameter of the hole is set exactly to the center of the mortgage or closing head, after which the well is made to the necessary depth or through channel. After that, several accurate blows can be easily knocked out.

Rivet Removal Tool

The second method is somewhat laborious, however, quite effective for heads that are clearly visible above the surface, that is, for semicircular and conical. You will need a special chisel, resembling a form of a chisel, with which you need to cut down a hat, causing sharp and strong blows on the rear end of the handle. Also, the chisel can also be suitable, but this tool is recommended only for rivets of small diameters. The fasteners with a rod of about 1 centimeter and more in such a way it is very difficult to cut.

The easiest method for removing rivets with protruding heads is to apply the angular grinding machine, in the spaciousness, called the grinder. It is best to install a cut disk for this purpose, and by clicking on the side to the head, gently cut it off. If there is a chance to damage the surface of the part with which the connection is removed, it is recommended to use a coarse grinding disk, with which the head simply becomes gently to the base. Next, by setting any sufficiently acute tool, for example, a displacement, you can easily knock out the rivet rod from the hole.
