How to make your own hands a corner clamp? Homemade corner clamps for welding with their own hands: drawings angular clamp for welding

In this article, I will tell you how to make a simple angular clamp for welding under 90 ° profiles and pipes. Good angular clamp in the store is quite expensive. The angular clamp, made by its own hands, is 100% accurate, assembled from healthy materials and almost eternal.

Step 1: Collect all the necessary materials and cutting blanks

For the assembly of fixture for welding at a right angle, I used the steel corner of 0.47x0.47 cm and the steel strip. The corner will suit, in principle, any, but I advise you to use a thicker metal. I took 2 segments of a 25 cm corner, the steel strip cut into segments 15 and 38 cm, the sections were made at an angle of 45 ° on each side (given the length of short sides). You only need to position all the details so that the clamp retains the rigidity after welding.

Step 2: Clamp Drawings

The vertex is open, between the inner edges I left 1.9 cm. This gap allows and combining the pipes in the center and approach them with welding. The clearance of less than 2.5 cm leaves universality to use, with a clearance value of more than 2.5 cm in it can already slip when welding the pipe.

In the photo - top view, on this side do not need to cook! All seams need to be done from the bottom side, just that they will not interfere with neither the upper side, nor when using the bottom.

Step 3: Collect the clamp and check the angle

After Okarite the surface of the metal, collect an angular clamp using 4 of the usual. Inner corner Check for accuracy with metal coal. With the exact coincidence of the sides of the square with the parties of the clamp, the square should not be peeled at all.

Step 4: We start welding on the reverse side

As soon as you collect your clamp, turn it over and begin to stick with welding on the reverse side. At first I welded one side and gave her to cool. The side needs to be done immediately, so that the details relative to each other are not shifted.

After the welding of one side is completed, turn the clamp and check the angle again. Then we grab the other side. After that, check the angle again. It is very important to produce the metal to cool between the welding of both sides. Then you can compensate the angle error if the metal will behave when welding. C-shaped clamps do not remove until the manufacture of the corner clamp is completed.

Although I have already made such devices earlier, in the manufacture of this specifically, I found an angle error when checking the carbon after welding one side. I simply cut the grabs, and reappeared steel parts with C-shaped clamps. After that, the angle turned out straight, as it should be.

Step 5: Complete welding

After the completion of welding, check the correctness of the direct angle with different coal. Sometimes it happens that the square was led to the corner no longer direct. Therefore, it is better to be restrained and check the straight angle by different coal. Note, the photo shows that I cut out the protruding outer corners of the lower crossbar. After welding, I just pulled the entire surface with a petal circle.

How to fix wrong corner

If the angle has not turned out exactly 90 ° or she led after a fall from the workbench, it can be fixed. First you need to find dents on the metal. In any dent, you can simply put the grumps with the welding machine. Then place a straight piece of metal into the clamp and check the angle of the salt. Cooks Loosen with a file until the angle is levels up to 90 °.

Step 6: Corner clamp in work

A homemade angular clamp can also be used outside, and from the inside. It is for this that all welded seams are made from the bottom. The photo shows examples of use if I was going to weld these pipes, I would additionally secure them with ordinary clamps. The last photo shows an example of adding a vertical element. It also explains why the gap between the shoulders should not be too large - otherwise the vertical tube would slip into the hole.

Be careful with the outer welding of pipes - the inner radius of the bendner can interfere with the fastening of the clamp pipe. Be sure to check this moment before starting to weld pipes.

At first glance, pretty simple welding works require, as a rule, a responsible professional approach. To obtain the highest quality results, it is necessary to additionally use special tools, devices, one of which is an angular clamp for welding made by your own hands according to drawings. With such a tool, welded joints of metal products are made much faster and easier.

Clamp - This is a universal device that is suitable for any types of working with metal structures. The tool is one of the most important devices for experienced welders. His absence leads to inconveniences of performance, respectively, to reduce labor productivity.

Welding clamps are made by the most varied parameters, may have a permanent or adjustable size of the oce. Fast-inspected devices are very convenient when the clamp of metal samples is carried out by means of a cam mechanism.

It is easy to make welding devices yourself at home. Many masters believe that various adaptations used for the convenience of performing welding work purchased in the store are not distinguished by the necessary reliability. They are better to make their own hands.

For the manufacture of such a tool, the following components will be needed:

steel sheet, thickness 9-11 mm;
nuts - 3 pieces;
large diameter washer;
pipe rolling billet, which should have an outer thread, similar to the thread of the nut.

Instructions for manufacture

The scheme of the manufacture of clamps in domestic conditions looks like this:

First of all, it is necessary to cut out of a metal sheet 3 strips of different lengths - 10, 25, 50 cm, the same width - 4 cm.
Next, we prepare 2 plates of rectangular shape, which will be needed for fastening the movable part, the stop on the static area of \u200b\u200bthe device.
We weld auxidant to the base of clamp. By connecting all the listed items should get a M-shaped design.
The next rectangular sheet weld to the smaller side of the device, the washers weld together.
We apply nuts to the moving element of the design (put them on "on the edge"). In this case, the separated rod to the base of the clamp should be located in parallel.
The welding is carried out from the outside of the first sheet of rectangular shape. A movable mechanism is attached from the inside from the edges.
The extreme stage of production of clamp - weld the washers with a plafhmy to the rod.

Made with your own hands The device provides the ability to keep overall designs made of pipe rolling parts, without the slightest shifts.

Corner clamp

The angular device is a universal fixing device, which is used for bonding, retention of products when performing their welding. Such an auxiliary mechanism sufficiently compresses the details at a prescribed angle, the savings of the welder makes it easier.

Clamps are made of different shapes, sizes. The most convenient option is quick-swamping devices.

With constant execution of welding work, it is recommended to have a complete set of excellent designs, tool parameters.

Construction of angular clamp

Such devices allow you to weld the metal products not only at right angles. Factory devices are made of several modifications, they can be used to connect pipes at different angles - 30-90º.

Features of the corner-type devices:

the clamping sponges are made of greater thickness, thereby increasing the degree of stiffness of parts of parts, welding seam during welding is not fused;
additionally, copper clamping screws are used, which do not allow the spike of the threaded sections of the clamp when splashing the molten metal on them, increase the operating period of the equipment accordingly;
to perform welding with electrodes under the installed angles on the docking areas of the clamp products makes more work zones.

The design of the device is the base in the form of a frame and a movable mechanism. The movable part of the device is often additionally equipped with a clamping lever (screw), which allows you to adjust the degree of compression of products.

Thanks to good mobility, the adaptation can fix products from a metal of various sections, parameters. For the most comfortable welding, it is possible to use several such fixtures of different configuration simultaneously. Most of the tools produced are calculated to weld the metal samples, the diameter of which does not exceed 39 cm.

On the angular clamps for welding, special handles of T-shaped shape are provided, which provide the ability to transmit an effort that is formed during the work process on the products processed. And the staples made of cast iron are withstanding the most maximum temperatures.

When selecting an angular clamp, it is necessary to take into account the type of alleged work. For example:

G-clamps are most often used to reliably fix metal samples having a small thickness.
F-clamps with an adjustable clamping mechanism are used in the processing of metal samples of large thickness.

Logging devices can be mounted in the garage, workshop, other rooms on desktops having a smooth surface.

Clamps are counted for auxiliary tool when conducting welding and other types of work. They provide dense compressing of blanks with each other, fixing parts based on processing. Different types of such devices can be seen in any workshop. In order to fix the angle between the structural parts, the wizards are used by an angular clamp. To save their own funds, they make this adaptation personally.

The corner clamp is made of duralumin, in view of this, it has great strength. The device is convenient because there are special installation holes on it, by means of which it is possible to fix it on the workbench. Usually, self-made clamps are used when assembling furniture items. In addition, it is possible to use it for carrying out carpentry, turning, plumbing and welding work both in production and in domestic conditions.

Constructive features

Corner clamp for welding provides the ability to weld parts from metal at different angles. Factory tools are available in various modifications. It is possible to apply them in order to join pipe products at an angle from 30 to 90 degrees.

The design features of clamps for welding works are:

Clamping sponges have a large thick. In view of this product, it is connected more hard, welded seam when performing welding is not exposed to bent;
The clamping screws from copper are used, preventing the spike of the threads of the device when it comes with drops of melted steel. Due to this, the period of operation of the tool becomes much more;
Welding clamp increases the workspace. This allows welding work at the right corners at the locations of the details.

The design of the tool includes a frame base, a mobile unit. Often this unit is equipped with a clamping screw. It provides an opportunity to change the degree of compression of parts.

Due to the good mobility of the clamp ensures fixation of metal parts of different sections, size. To increase the convenience of welding and performance, it is possible to apply several clamps of various configurations. Most of the manufactured devices are designed to connect parts from the metal, the radius of which is not more than 19.5 centimeters.

On the welding clamps of the angular type there are special handles in the form of the letter "T". They allow you to report an effort that is formed during processing to processed parts. Cast iron brackets are capable of performing their task even in high temperature conditions.

When choosing a device, it is necessary to take into account the type of work that you intend to conduct.

G-clamps are usually used for rigid fixation of steel parts that have a small thickness.
F-clamps that have a clamping device that can be adjusted is used when processing steel parts having a greater thickness.

Fast pressure tools can be installed in garage rooms and workshops on special tables that have a smooth table top.

We offer to watch a video with a selection of homemade corner vice, which are made with your own hands.

How to make a clamp

Most of these devices has an angle of fixation of 90 degrees. However, today products are produced in which it is possible to change the angle of attachments. They are somewhat more expensive, in view of this it is recommended to make an angular clamp with their own hands using or without drawings.

Such a tool is constructively simple, almost every homemade craftsman can make it without much difficulty. The most suitable material for creating clamp is iron.

The manufacture of the device is carried out according to this algorithm:

Creating a structural base. For the manufacture of the main part of the device, it is recommended to use leaf iron having a thickness from 8 to 10 millimeters. The fixation component is the corner of the required value. It is desirable to fix the elements by means of electrical welding, because the use of thread is not so secure.
Installing clips. For the manufacture of a pressure screw, you need to use two or three nuts that are connected to each other welding. It is necessary to make a bracket with a threaded hole with a thickness of 30 to 40 millimeters. The bracket is fixed by bolts. If the thread is rapping, it will be easy to replace it.
Angle formation. Particular attention must be paid to the position of the clamping brackets. When connecting, the corners must accurately approach each other. To ensure the perfect connection, 1 corner is welded with clamp. After that, a second corner is put on it, which is pressed against the bracket and boils with it.
Check the mobility of the main part. On the sides of the tool you need to mount the guides that provide the ability to move the internal base of the device. To do this, cut a groove having a width of eight to ten millimeters on the bisector of the corner device.
Drilling holes. Using a boring tool in the upper base of the device, which twists the bolt with nut and washer, holes are created. Basins should move freely relative to each other. It is recommended to use a bolt that thread does not reach the head. In addition, the head can be fixed based on the bracket.

Also, the angular clamp can be done according to such a scheme:

Cutting from a metal sheet of three strips of different lengths (100, 250, 500 mm), the same width (40 mm).
Preparation of two plates in the form of a rectangle.
Switching the plate to the base of the tool.
The welding of the second plate to the side of the tool that is smaller.
Welding the washers with each other.
Application of nuts to the mobile component. The rod that is twisted should be parallel to the main part of the device.
Welding is performed from the outdoor side of the first sheet in the form of a rectangle.
The mobile element is fixed inside the edges at the edges.
Babying the washers to the rod (plafhmy).

When using ordinary clamps, difficulties may occur with the performance of certain works. It is due to the limited arrangement of the device. It can be placed only at an angle of 90 degrees. To eliminate this restriction, you need to place a plug-in bolt in the tool. It is possible to use the clamping adjustable screw. Through it, it will be possible to select the desired angle, to secure.

It is worth not to forget that to create the right welded connection, a high-quality tool is required, providing the opportunity to facilitate welding, prevent the occurrence of non-dusting, edible.

So that the manufacturing process becomes more understandable, we recommend to explore the video lesson to create this device.

Corner clamps are necessary for assembling a variety of structures. With their help, you can securely fix the workpiece. Most often used to build furniture, when performing welding, plumbing and joinery. A corner clamp of 90 ° is often used, if necessary, you can make a device for any angles.

Types of clamp

Simple, providing fixation of parts with a workplate plane.
Corners designed to hold two blanks at the desired angle.
Volumetric capable of fixing three blanks in three different directions.

The first type is made in the form of a C-shaped bracket with a threaded clamp. Scope of application - Treatment of wood, metal, plastic bases. The second type is the most commonly used.

Most often, the angular clamp is used to fix billets at an angle of 90 °. But there are samples that allow you to change the angle to the desired value.

The third type of fixators is needed if the specificity of the work provides for the implementation of large one-type processes.

Factory models are quite expensive. Solution - to make clamps yourself.

The angular and volumetric clamps are made on the basis of a simple design, referred to the first category, and additional parts that can be found in the home workshop. Dimensions, strength characteristics depend on the manufacturing material. Usually, parameters are focused on the type of parts being processed. The article describes how to make joinery clamps from, a diagram of assembling corner clamps for working with metal parts is presented.

Plywood clamps

For the assembly of furniture, which are often used that are fixed at right angles. It is recommended to make a fixture based on simple clamps. This will require:

a sheet of plywood or chipboard with a thickness of 8-12 mm;
square or rectangular wooden bar;
electrolovka or hacksaw;
electric drill with set of nozzles.

Two or more rectangular triangles with custom rubles are cut from plywood or chipboard. The angle of 90 ° of each segment must be as accurate as possible, otherwise the finished design will be low-quality. In each corner of the triangle form a hole. It must correspond to the size of simple clamps taken as the basis.

It is necessary that the distance from the edge of the opening to the triangle category is 10-15 mm.

The device is experiencing in practice. To do this, the homemade triangle is pressed by the usual clamp to the leaf processed, align on the edge. The second simple clamp fixes the following part at an angle of 90 °. To fastening it is reliable, two triangular shapes are used along the edges of the joint.

Corner clamps for metal blanks

For working with metal parts, iron angular clamps that enhance the clip are used. Metals are stronger than wood, fixes them need a stronger tool. Processing is often conjugate with the process of welding, high temperatures will quickly lead wooden elements. It is better to give preference to the gland. It is not afraid of electrical arc, high temperatures, mechanical exposure.

Metal angular clamp is made by the same scheme as plywood. But the auxiliary tool is made from sheet metal with a thickness of 8-10 mm. Fixing elements are collected from a metal corner of a given size. For greater reliability, the corners are welded. Threaded fastening will also fit.

The screw clamp is made of three nuts with each other. You can create a bracket with a threaded hole with a diameter of 35-40 mm in the center. Fasten the device with bolts, which allows the thread in case of breaking the threads to carry out a quick replacement.

The internal base of the adaptation is moved by guides. For their manufacture in the bisector of the triangle form a groove with a width of about 10 mm. Drill the technological hole in the upper base of the figure. It is supplied with a bolt and twisted with a nut. So that the mutual movement of the base is not difficult, the work was performed correctly, the thread should not reach the bolt head.

Angular clamp is easy to make yourself, there is no need to purchase the factory clamp.

In order to speed up and simplify the work process, for example, when working with metal products, you will need a couple of angular clamps! In addition, after welding, the metal clamped into the clamp, does not lead as without it, and the angle remains 90 degrees.

It is not difficult to make an angular clamp with your own hands, it is enough to have a small residue from the profile pipe, the hairpin, and naturally the bolts with nuts that I think everyone.

Visually clamp can be divided into two parts: base and presser part.

First of all, we make the basis of the proftrub 25 * 60 as shown in the photo.

The base from the profile pipe 25 * 60

First you can collect on the patches, then completely slaughter the seams and wear the grinder well.

Then, from the same pipe itself 25 * 60, we cut two segments of 160 mm and weld them along the edges. You need to cook only from the outside and from the ends, because From the inside, the workpiece and seam can be pressed.

We weld the outer sponges of 90 degrees with respect to each other.

External and internal fitms should be exactly 90 degrees in relation to each other, after welding, make sure that they do not move and they did not hurt them.

The next step is the manufacture of mount for the presser part.

Cut a segment from pipe 40 * 40 long 30 mm and cut one of the parties, making it the letter "P", then weld it to the base. For fastening the screw, we need to drill two holes on the 8th and third (lower) hole at 10, so that the end key would be held in it (hereinafter you will understand why).

We make fastening for the screw.

The first part finished, now proceed to the second.

From the same pipe 25 * 60, we produce internal fittings (sponges), on the outside, I got 105 mm.

We press them with clamps to external clamps and weld with each other.

We make internal fit pictures.

Cut two triangles with a thickness of 2 mm and welds to the inner clamps from above and below. Drills through (in two triangles) Hole to 8.

We weld two triangles and drill a hole.

For fastening the screw in one and in other parts, we weld the wren on 8 and 14 with each other (as shown in the photo). We make two pairs.

Make the screw for the screw.

Having a single nut on the screw, and for the second you need to prepare it.

We calculate the screw in a circle a little more width of the nut and in the face we cut the thread on 8. We wear a puck on it, the main thing that it was smaller diameter than the screw thread, wear the mount cooked from three nuts and tighten the bolt. The fastening should be freely rotated, and the groove was done in order for the screw during the rotation of the screw, the nut did not wind up on it, but freely rotated.

Moving

After that, secure the screw to the presser and the main part and make a knot on it, just cooked from nuts and a bar (or a long bolt). All clamp is ready, it remains only to paint and let it in the case!
