Many drivers, facing the concept of "reverse hammer", do not understand what it is. Although, if you did not have to independently repair the body, with a great perceptibility you never seen a similar tool. But if you still have to repair the body - without a reverse hammer can not do. In this regard, the purpose of the article below is not only what the reverse hammer is, but also how to make a reverse hammer for body repair with their own hands.

What is the reverse hammer for body repair

In the process of working with the car body, the most severe and responsible part is Richtovka, that is, aligning the body surface. To fulfill this task, even specialists need to have professional equipment under hand to which the reverse hammer belongs.

IN classic version Reverse hammer is a pin, made of metal and having a length of 50 centimeters. The diameter of this pin is only 2 centimeters. On a pin there is only two elements: on the one hand rubber sleeve, and on the other - a small metal washer. The task of the latter is to hold the sleeve and do not allow vibrations from shock to switch to the hammer case.

In addition to this, many reverse hammers also have hooks, with which the device can capture brackets welded to the body, and thereby reliably hold on it during the richt.

Appointment and types of reverse hammers

Often the reverse hammer is used to eliminate small dents on metal parts of the automotive body, to which direct access cannot be repaired, or to align them from the reverse side. With the help of a reverse hammer, it is very convenient to work with automotive thresholds, wheel arches and racks.

Important!Reverse hammer Designed to work with small areas in areas, so it will not work for the adjustment of large dents on the roof or trunk. This is connected with the technology of work, which is used during the use of the reverse hammer, and with its size.

There is its own classification of reverse hammers for the body repair, which includes:

Vacuum hammers.

Spotters.

With garish (Two and three are used).

Inverse hammers working with a pneumatic mechanism.

From the type of reverse hammer depends on the feature of the richtoval work. To equalize the surface of the body of a new car, it is better to use a vacuum reverse hammer, as only it allows you to perform such a difficult work without preliminary removal of the paint and varnish. In the same case, if you are going to apply one of the remaining types of hammers, the part of the body where the dent is located will first need to thoroughly clean up with the help of sandpaper. Otherwise, the paintwork will still be damaged by the reverse hammer.

How to use reverse hammer

The entire process of stringing dents on the automotive body using a reverse hammer should be performed in the following order:

1. Rinse with water with the entire work surface so as to remove all the contaminants, and be sure to treat the entire surface with a degreasing means.

2. If necessary, remove with working surface paintwork. For this, it is practical to use the grinding machine.

3. We weld to a plot with dent round repair washers.

4. To the reverse end of the hammer, attach a special hook, which should go complete with a tool.

5. Hook a hook behind the puck.

6. Holding the tool with one hand behind the handle, take the second hand for the weight and direct it to the handle. In this case, your movement should be as sharp as possible.

Due to the fact that the reverse hammer is tightly linked with a body surface, with each of your movement of the weight, the reverse dent is aligned. At the same time, the more stronger you will carry out the weights of the weight, the faster the car body string will go.

Attention! It is necessary to work with the feed hammer very carefully, since when using it in the middle of the body, you can achieve the opposite effect. We are talking The fact that very often new defects may form when aligning one dent. Therefore, in such parts of the body is more efficient to use more professional equipment.

In working with a reverse hammer it is necessary to behave extremely carefully. In no case, do not rush and after each impact, evaluate how the dent changed. This will help you to avoid the formation of new dents on the edge of an existing defect. But if you work slowly and correctly perform all instructions, it is possible to eliminate a small dent literally in a few minutes.

Often, it is impossible to do in repairing the body of the car without a reverse hammer, although each time you need to soberly assess the situation, and if the area of \u200b\u200bwork is too big - to resort to the use of other tools. As for the reverse hammer, then, fortunately, such a tool for bodywork can be made with their own hands.

We are engaged in independent manufacture of reverse hammer

Return hammers today can be bought in any automata. It is worth noting that they can be sold and as a separate unit, and as part of a set of tools specifically designed to repair the body. But since there are no complex mechanisms in the opposite hammer, it can be done at home.

To make your own hands tool for body repair, you will need to prepare some materials:

The pin from durable steel, a length of 50 cm, and with a diameter of 2 cm.

Important! For the manufacture of a reverse hammer, you can use a thick diameter pin, however, the service life will be significantly reduced, since under the action of constant blows, the thin base will be rapidly collapsed.

The handle or nozzle, which can be put on the steel pin. The handle must be made of ebonite or rubber.

Welding machine and protective devices to it (gloves, mask).

Steel hook thick no more than 0.5 mm.

A 16-centimeter hih is about 6 cm thick.

Steel washers in an amount of 2 pieces (a diameter of 2.5-3 mm is suitable).

All other works on the manufacture of the reverse hammer for body repair are recommended to be carried out in the following sequence:

1. If necessary, we clean the metal pin from rust by grinding and process the perfectly smooth surface to any degreasing means.

2. One of the ends of the pin it is necessary to fix the hook. If the hook has a thread on one side, it can also be performed on the pin, creating a removable connection. Otherwise, for fastening the hook will have to use welding.

3. At the base of the hook, it is necessary to place the puck, which will prevent the movement of the weights to the working surface and random damage.

4. To put on a gircuit on a metal pin, it needs to do a hole, the diameter of which should be 1 millimeter larger pin diameter. Thanks to this, the weight will be able to move freely, and you can give it any possible acceleration.

5. The weight is put on the pin, and steel sheets are mounted on top of it, which will allow you to secure it as reliably to strike through the body. On top of it, it is also worth putting on and welding another puck so that the weight does not hit the handle.

6. Start fixing the handle. Note that it should sit on the pin as securely as possible, so if possible, it is necessary to welcome to the base of the pin.

This is completed on this process of manufacture of reverse hammer. As you can see, if you prepare materials and tools in advance, not more than 40 minutes will leave all works. You can even make a reverse hammer with a vacuum sucker, which will significantly simplify the execution repair work By body. To do this, instead of a hook, which the tool is attached to the working surface, it is necessary to use special suckers that will be able to ensure the same fastening reliability.

One of the most successful devices for body repair is the reverse hammer. The reverse hammer is successfully used during the repair of thresholds, arches, racks where there is no access from the inside. The construct of the reverse hammer is very simple, the base is a steel bar with a diameter of 20mm. and a length of 500mm, the weight (sleeve) is hoping on one side of the rod, the rod is made in the form of a hook, and on the other hand, the washer is welded so that the sleeve does not fly out, and the reverse hammer strike force was transferred to the rod.

Principle of operation; Before starting work, it is necessary to get acquainted with the repair section of the body of the car, the place to be stretched to be stretched to the metal and weld repair washers. Next, the crochet of the reverse hammer cling to the washer and the light blows pull the dent, repeat this operation until the dent removal is completely removed. To remove oblong dents and edges, weld, slightly sucked, through the holes of the metal rod.

Important: In no case do not use the reverse hammer for repairing large body squares, these are central parts of the roof, hood and lids of the trunk, since as a result of welding, the washers can be pulled out the metal, the result will be a crying part on a landfill. Also there are reverse hammers with two, three weights, which allows you to adjust the force of impact.

Hammer inversely do it yourself

For the manufacture of reverse hammer, you will need a steel or stainless bar with a diameter of 20 millimeters and a long 500 millimeters, a steel girome (sleeve) ebonite handle and hook. The hook can be made independently from a sheet metal with a thickness of 4 mm. It should be noted that for the manufacture of a vacuum reverse hammer, instead of the hook you will have to adapt, as it does not ridiculously sound a suction cup from the vanza.

Important: All items of the reverse hammer must be treated with a file and all burrs are removed and off. Do not forget the reverse hammer it hand tool, Make him so that it was nice to keep in your hands

Vacuum reverse hammer

For repair of the body without painting, vacuum reverse hammers are used, as they do not violate outdoor painting Body car. In addition, they can be used when repairing large body squares.

A reverse hammer for body repair is used when richtovka machines. This design allows you to pull dents in working with the body in front of the painting car. In this material, in addition to the information, the photo assembly assembly is presented, independently allowing it to weld it. Please note that this hammer is intended for straightening dents with welding, not suction!

To make your own hands a reverse hammer, we need a little metal. Below is a drawing drawn; Diameters and lengths are given in relation to this particular opposite hammer. You can apply your sizes, use your pipes - the main thing to work!

According to the design in the opposite hammer should be a rod with a crochet, a bore, emphasis and handle: the right hand hold the handle, with your left hand, we give a boo on the progressive movement, hitting the extra.

So, we will need: pieces of two pipes different diameter (We will call them a small and large pipe), while the small pipe take a little greater length than big; a piece of rod; A pair of glazers from sheet iron and one of the iron is thickening and another handle. I don't point the diameters and lengths in the text, they can be any at your discretion, and my, see in the figure at the top.

Cut from sheet iron Round Pynet of this diameter as the diameter of a large pipe (the diameter is shown in a red circle in the photo at the top). Drills in hardware hole with a diameter as the diameter of a small pipe. We weld a small pipe (photo at the top). Clarification. I first cut the square slightly more, drilled the hole, welded the pipe, and then made the range of the red circle from the square, the grinder cut out.

And you can immediately cut the circle, drill and welcome- as you want (in the photo below the other option of starting work).

What we did, we insert inside the big pipe and cook in a circle (in the photo at the top and below - shown from different sides).

We make another Pyhat, the same as first. I did this: I cut a bigger square, drilled the hole, put on a small pipe (see Foto at the top), noted the diameter for a large diameter true Cut and cut off with a grinder. What came out in the photo.

Cut a small pipe, leaving a steam of millimeters on the welding-approximate cut line in the photo below.

Put the pipe with sand. Sand Take dry. We are tamped like this: just knock on the floor, the sand "sits9, add sand and again by trambus.

We score sand up to top and cover with Pyatak (photo at the top). Evalid everything: on the inner diameter to the small pipe and the outer to large.

This is what came out (photo below), it's a bore.

On the this stage Making a reverse hammer We need a bar, a piece of iron for the stop and a handle (photo below).

Rod. Slicing the rods, do not forget to leave the hook bend tolerance.

Focus. It may be from a piece of flat iron, for example 4 mm. The focus should keep the strike of the booze and not bend. Nuance: I caught a piece of iron with a thickness of 2 mm- not very thick, but in the form of a bracket (fig. Blue in the bottom).

A pen. Maybe from anything. From the old Bulgarian, from the old kitchen utensils. You can, as a last resort, even a piece of the same little tube.

Flex a hook from the bar. About revealed on the bar bore. Another end of the rod insert into the hole of the stop and cook from the reverse side of the stop (the picture at the top). Then put the handle and also boil from the same side. Thus, all welding is carried out from the side of the hammer handle, but not from the side of the Boyhead.

So, that's what came out, with your own hands the reverse hammer is ready.

For work, you can buy cheap washers big diameter And to weld them, here in the photo at the bottom stretch the middle rack: they welded the washers and the reverse hammer is going to straighten the body element.

What is needed to make a reverse hammer with your own hands?

Body repair is a challenging operation that requires certain knowledge, special tools and devices. One of these devices is the reverse hammer. This is a simple tool that is easy to make with your own hands. For this there are many photos and videos on the Internet. You can also download the drawing of the simplest version of the device.

What is a reverse hammer and what is it needed for?

This tool is a device that allows you to attach a certain force to the metal with limited access. The device is applied to align small sections of the deformed car, which suffered from small accidents.

Some parts of the car body can be aligned with a conventional rubber hammer, applying blows from the reverse side. However, most surfaces do not have such access. In such cases, a reverse hammer is necessary. Its tip is fixed at the place of deformation, and the help of cargo, which is located on the other end of the device, the delayed jerk force is transmitted to the surface.

Before making a reverse hammer, you must describe the varieties of this tool. It will be needed to make the drawing of the device you need, and then make it.

Varieties of reverse hammer

Despite its simplicity, this device has acquired several versions. Each option is applied in some cases that depend on the type of damage and skill of the specialist. In general terms, the design of this device is the same as its principle of operation. Differences are available only in the method of fastening the tool to the body.

The most common reverse hammer is a metal rod, at one end of which the hook is located, and on the second - the load with the focus. The hook joins the washer welded to the place of deformation. Apply shock efforts into cargo, the deformation is pulled up to the desired moment.

The second, the same simple option of the reverse hammer differs from the previous one that at the end instead of the hook is the usual thread. To align the surface with such a device, you need to do the hole in the center of deformation, push the end with the thread, and on the reverse side, fasten the washer and nut on it.

The most complex type of this device has a vacuum device at the end, which is fixed on the surface of the deformed part with a sparse air. The suction cup can be activated, both from the compressor and the usual method. This type of device allows the strainer to correct the uncomplicated damage to the body, and at the same time save the paint coating of the site, if it is not damaged.

Independent manufacture

Make a reverse hammer at home with your own hands simple enough. It does not take much time, and does not require special materials and tools. For a more visual understanding, you can see the video on the Internet. Primitive drawing will not be superfluous.

For the manufacture of this tool, you will need the following:

metal pin is about 50 cm and 20 mm in diameter;
cargo that has an inner hole;
thread cutting tool (optional);
welding machine;
bulgarian.

If it is decided to make a reverse hammer with a hook type of fastening, the hook is made at the end of the pin. You can make it using a vice or passage. Or to welcome welding apparatus Already ready hook from another device.

If the tool is done with a threaded capture, then the thread is cut on the pin the corresponding tool. A lot of threads should not be chopped, as the metal metal is quite thin.

After the tip is made on the pin, the load is worn, which is limited from the reverse side of the tool. This can be done with welding, or use threaded stop. The second method is adviser, as it will allow the use of different loads by weight depending on the required effort at the end of the return hammer.

Again, to clearly understand how it happens, the easiest way to watch the video. If there is no such possibility, then the procedure for working with this device is approximately following:

the tip is fixed on a deformed part of the body;
detail of cargo strikes the desired position;
if the effort is not enough, the cargo changes to heavier.

When pulling out a relatively large metal plot, you can spend a few washers on the same line and turn the pin through them. To make it right, it is advisable to watch the video on this theme. Then this pin joins the crochet, which is welded to the device and is delayed with the metal, aligning it to the desired state. When using this method, you should be careful, since the welding of a large number of washers can excessively pull the metal, and spoil the body part.

SGDUBROVSKY\u003e Blog\u003e Reverse hammer. The dream came true.

Hello everyone.
A very long time I wanted to make myself a reverse hammer, but there was no possibility.

Yesterday I was psychulin and remembered the base for the metal.
Bought:
1. Round Round d \u003d 10mm

1,5 meters;
2. rod round d \u003d 16mm

1.8 meters;
3. Nut M10 - Stuff 4;
4. Nut M10 long - 2pcs;
5. Nut M12 - a pair of pieces;
6. Washer for 10 - 2 pcs;
7. Puck for 12 - 2 pcs;
8. Cap M10, step 1.5.

It was not useful for all nuts and washers ...

"On the eye" we choose the length of the bar for 10 - it will be the basis of our hammer and ruthlessly sawing.

Then on the end of the rod we cut the thread with a scatter.

Sliced, put to the main bar, tightened with a painted scotch and grabbed welding. Then he took off, ticked tightly.

After we put the rolling part into place, screw the nut on 10 on the thread on 10 and boil it - the upper limiter turns out.

How does the reverse hammer for the car richt

One of indispensable tools To rattling cars - this is a reverse hammer for body repair. His destination is the straightening of small dents on racks, thresholds, arches, i.e. on the plots where there is no access from the inside of the body. This adaptation will be discussed in this article. First we tell how this device looks like.

What does he represent?

In its design, the reverse hammer is quite simple. Its base is a metallic rod, the diameter of which is 10-20 mm, and the length of about 50 cm. The steel sleeve (weight) is hoped on the rod.

From one end, the rod has a shape of a hook, from the other - the washer is welded so that the weight does not fly, and the shock force of the device would be transmitted to the rod. Often, in the configuration of industrial hammers there are several different hooks that are needed to capture the bracket welded to the repaired section. There are also reverse hammers that have two or three bushings. This makes it possible to adjust the shock force when aligning dents.

How to use the reverse hammer?

First you need to explore the repairing section of the car to choose a hook in shape of dents and calculate the degree of application of force.
After that, the site of the body surface that needs to be repaired should be cleaned of paint and soil to metal.
Next, it is necessary to privar special repair washers (brackets) to dent.
Then the hook tool hooks for the brackets.
Then with light and neat blows you need to start pulling dents.
This process must be performed until the damage is fixed.
In order to remove the elongated edges and dents, it is necessary to weld a few brackets, and then, while looking through their holes, the hammer rods, delete the defect.
After that, the spilled plot can be primed and re-covering the suitable color of the paint.

From the disadvantages of this device, it should be noted that with dents you have to remove the paint, even if it has not been damaged. In addition, you will not correct big damage to it.

Ordinary reverse hammers are extremely recommended to use for extensive dents when repairing central sections of the hood and roof, as well as the car trunk lids. The result of the welding of the bracket can be a strong deformation of the metal and its pulling. As a result, the detail will have to be replaced completely.

There is a special variety of described fixture - a reverse vacuum type hammer. His distinctive feature is that when it is assisted, it is possible to repair the extensive area of \u200b\u200bthe car of the car. In addition - before working with it, it is not necessary to remove paint.

How to make a device yourself?

To make this device with your own hands, you need an iron, and even better than steel (stainless) rod 50 centimeters long and a cross section of 10-20 millimeters, as well as a steel sleeve (weight), hook and handle from an ebony.
Hook-grip You can either buy it already ready either to make steel having a thickness of 4 millimeters.
To make a vacuum variety of reverse hammer, you can use the suction cup instead of the capture from any tool, for example, a conventional vehicle.
After you collect the device, carefully process all its elements first with a file, and then emery skurt so as to remove all the jar and burrs.
After that, try new tool On some unnecessary automotive items.

Reverse hammer for metal straightening - how to make it yourself and how to apply

Contact tool with a magent body makes up a couple of millimeters, but it is enough to align dents

No car service or workshop for the repair of the bodies do not cost without reverse hammers or similar devices. I will tell you what a reverse hammer is how to work and how to collect it with your own hands. I am confident that such a tool will take a worthy place on the shelf in your garage and will be useful for body repair.

All you need to know about the instrument

To straighten such a dent, you need to shoot the entire bumper, and this is not easy and not easy - much faster and more convenient to stretch the plastic on yourself

If a dent appeared on the automobile body, then it's time to purchase a reverse hammer or make it with your own hands. After all, it is this tool that will help to align the metal surface to the initial state.

This tool is a type of hammer that strikes not like a jackhammer, but from the surface, pulling it on itself. The instrument device is extremely simple - the rod is freely walks the weight, and the rod is equipped with a handle.

The drawing shows the main elements in the design of a rotating hammer - the blue arrow indicates the movement of cargo

The rod is made of a metal rod or from a metal thick-walled tube with a diameter of 2 cm and a length of 50-80 cm. The weight is a cylinder 15-20 cm and weighing 300-500 grams. Through the cylinder passes through a hole in which the rod is freely moving.

At one end of the rod rigidly fixed handle. The handle is made of metal or it provides for a metal Garda, to which the impact is accomplished;
On the opposite of the handle, the end is a suction cup or point for spot welding. Despite the simplicity of the instrument, the price of the device begins with 2 thousand rubles (prices are relevant for spring 2017).

Why is it not an ordinary impact hammer for the batting details, namely the reverse? Given the nature of the damage when dents, it is possible to eliminate the defect, having a mechanical load on the metal in the desired direction. Purge the damaged body element to knock it out in the opposite direction, it is impossible.

When choosing a shock device, damaged metal on the body element can be pulled out simply and quickly. Moreover, the body element does not even have to be removed, since all the work can be done right by car.

Disassembling the drum brake node is a difficult lesson until you try to apply the reverse hammer for Spotter.

An alternative way to apply the tool - removal of brake drums with scurrous studs. Another tool here is not to be taught, but welding a feedback hammer or screwing it with a bolt, the dismantle can be disassembly and quickly.

Tool varieties according to the method of fastening to the surface

Types and their description

Surface preparation. The damaged surface of the body is processed by a wire brush on the grinder, up to completely removal of paint. After rough removal, the metal is burned with a large sandpaper.

Before starting to work by the spotter on the body, be sure to remove the minus terminal from the battery!

Pull the metal. The tool configure is set to the beginning of the dent, that is, where the metal is just starting to bent. It is necessary to put a mark and grab the terminal with point welding.

We give the metal to cool, then the weight with the effort to hit the handle. We repeat the blows until the metal is curved.

We shake or cut off the welded trick and weld it again 1-2 cm further along dents, and continue to pull it out.

Metal stripping. After the whole demerican is stretched, we clean the protrusions from point welding. We regularly apply a wide spatula or ruler and, if necessary, additionally remove the protrusions.

Application of SPOTTER MOX. It is all easier - the electric conflict is applied to the metal, the button is pressed on the handle and you can shock.

At the end of the drawing of the metal, the body element should also be cleaned from the welding relief.

Reverse hammer is a tool for car body repair and can be made with it.

The product consists of several parts: arms with a length of about 50 centimeters, two locking nuts with washers, weights and several hooks (other nozzles, depending on the target use).

The principle of work is that the hih's fixed on the metallic rod with each subsequent movement strikes the locking nuts thus influences the fixed hook, which pulls dents or bends of the deformed metal.

Materials and Tools for Manufacture

Qualitative reverse hammer can be made in garage conditions without using serious equipment and with minimal cost on the material. The manufacturing process in the presence of all necessary elements takes about the 1st hour.

Basic tools and materials for the manufacture of reverse hammer:

Steel rod 12 mm about 50 cm long;
Tape, adhesive tape;
Steel rod 16 mm;
Two large steel washers with nuts;
Tool for cutting thread;
Electric welding;
Visits for fixation.

Reverse Hammer for Body Repair: Step-by-step instructions

The process of manufacturing a reverse hammer begins with the preparation of the material. As a handle, a metallic rod with a thickness of 12 mm and 50 centimeters length will be used.

1. Production of mobile "Giri"

Giray for reverse hammer is made of a rod with a diameter of 16 mm. The rod is cut into 5 smooth parts of which the length of which is equal to 12-16 centimeters. The rods are fixed on the main handle with the help of the isol, and then their welding is carried out with each other longitudinal welding seam. It is important to take into account the lack of welded slag on the surface of the handle.

2. Cutting the threads at the top of the thread hammer

The thread is cut under a long nut for about 2-3 centimeters on the rod. This procedure should be carried out with regard to all angles as it depends on how strong the reverse hammer for the straightening.

3. Production of bent hooks for reverse hammer

These hooks are necessary for alignment of parts in different planes. Production of elements is carried out in individual order Depending on the needs of the user. The bending procedure is carried out with the help of a sledgehammer and stop.

4. Cutting the thread of metal hooks

On ready-made hooks for a reverse hammer, a thread is also cut to connect two elements of this tool using a long nut. Cutting should occur under an even angle so that two connected parts are without distortion, otherwise a disruption of a hook with threads during the workflow is possible.

5. Installation of locking washers on the handle

To get a high-quality universal reverse hammer, it is necessary to make reliable locking washers. These elements take most of the load during shocks, so their installation should be carried out with respect to all angles. At the end of the handle, the thread is cut into which the nut with the washer is screwed. A rubber handle made from a tape or rubber hoses is mounted before installing the washer.

6. Check the performance of the reverse hammer assembly

The manufactured reverse hammer should work without jamming and any difficulties. All mechanisms move smoothly.

The carving on the hooks and the locking nut must necessarily be lubricated to save the nodal mechanism.
