Assembling the machine for armature bending by one

The machine for bending reinforcement is a necessary device used during construction as well as industrial work.

With its help in the future, it is really possible to manufacture both reinforced concrete and metal structures.

There are times when you can do it yourself, but most often the thickness of the products is so large that it is possible to achieve bending only with the help of special tools.

Modified bending machine for reinforcement allows not only to give sheets and other materials the desired shape, but also to cut them.

Also many devices allow making rings, fixing clamps and parts, loops, which are used in installation and construction, from wire, pipes or other raw materials.

Despite the complexity of the design, the machine can be designed and assembled by hand. To do this, you need a prepared drawing, tools and knowledge of the principles of the device.

How does the machine tool work?

For domestic purposes, a self-made manual bending machine for reinforcement is used, first of all, when erecting a foundation.

Without reinforcing parts to make a reliable base is almost impossible, so the question arises - how to make a frame, how to bend the existing reinforcement?

Of course, today in the market you can find a huge selection of professional equipment, but the price for it can be very high.

Such devices are bought for industrial purposes, arrangement of shops, construction firms. For your own personal use, a design that is assembled with your own hands.

If we talk about technological standards, the machine for bending reinforcement should have three shafts.

One of them is stubborn( holds the bars at a certain angle and fixes them), the second serves to fold the material around the main shaft - the third one. It is also called central.

Depending on the type of construction, a manual bender for armature bending and mechanical is distinguished.

The latter is widely used in everyday life, because it has a compact size and a relatively small cost, and work, due to simplicity, everyone can do it.

There are also hydraulic or pneumatic devices. So, the hydraulic machine for bending reinforcement can bend the material at an angle of up to 180 degrees, ensuring the absence of breakage.

When constructing one's own hands it is necessary not only to stick to your project, but also to pay special attention to the quality of fasteners( after all, the load on the parts can be very high), and take care of the organization of protection.

A slipped rod can cause serious injury.

Therefore, it is often possible to find plexiglas protection on the simplest bending machines for fittings, which can be easily done by yourself.

Also if you have experience in assembling machine tools, you can provide your design with speed switching to regulate operation.

Some models are equipped with a foot panel, which allows you to change the direction of the valve supply without problems.

How to make a home machine?

In order to handle the manual bending machine for the armature, you must first prepare a whole range of tools.

If you are keen on assembling and building, then finding such details and the necessary equipment will not be difficult.

First of all, electric welding is needed. For a device that can handle even the sheets, you need a solid foundation, a punch, clamps and a clamp.

Operating principle

1 - bending disk fixed to the vertical shaft;2 - finger;3 - hole for the finger;4 - stops;5 - reinforcing bar;6 - axial support

The punch can still be assembled from metal corners. Suitable for assembly and cutting of channels.
The base is carved exactly by the latter.

Here the fifth or sixth number of the model of the channel is suitable. But the length should be chosen small - not more than 50 centimeters.

The bending machine will consist of a lever, punch, clamp and the main part, on which the pipes and rods or sheets will be located.

First, on the basis of the chosen location, an axis is made for clamps - it will be more convenient to navigate through it.

However, remember that the clamps should be 6 mm less than the workpieces made under the base.

From the ends they also keep at a distance of several centimeters - without such an indentation it will be impossible to correctly distribute the load.

For the lever, a wire, diameter that should be no more than 15 millimeters, is suitable.

The base is bent in the form of the letter "P", and it is welded with a welding machine to one of the stable corners. From the edge, there should be an indentation of about 5 millimeters.

Next, steel bars are welded to the punch, and chamfers at an angle of 45 degrees are taken from the ends of the workpiece.

To properly weld all the details and check the angles, evenness of the structure, docking, you can first use the vise, and already on them to conduct welding work.

Thus, it will be possible to make a preliminary skeleton, which can always be remade.

In addition, where possible, it is better to use bolts instead of welding. So it will always be possible to rebuild or dismantle your design, supplement it with details.

If, however, preference is given to welding operations, then it is first necessary to perform a trial bending procedure. If all the steps are normal, then you can weld the parts together.

How to add elements for cutting?

In addition to the fact that the homemade device can be given different shapes of products, it is really possible to make a machine for cutting reinforcement, which will combine both functions: cutting and bending.

Of course, it's much more difficult to design it with your own hands, but it has more applications. The easiest option is to make a carved disc using a Bulgarian on the base.

The machine for cutting reinforcement can be made in any room. Its design can be either folding or integral.

In the first case, such an apparatus can easily be dismantled and assembled already in a new location.

If to speak constructively, then except for bending shafts, the machine for cutting the fittings must consist of an engine, a cutting blade or a disk and the surface itself where the blade will be fixed.

Knowing the operating principle, you can easily make your changes to the feeding mode.

The power must be determined beforehand, before the rebar is assembled.

Professional devices have high power - about 2000 W.

Despite the fact that it is possible to select smaller indicators for household purposes, do not forget that metal remains metal in any situation, and to cut it, you need a big load.

Another characteristic directly related to the engine power is the gear selection.

Most often this is a belt or friction friction transfer. The engagement in this case can be chain, worm or dentic, it all depends on what materials you have at hand.

Belts give a quiet operation, but the likelihood that such a design will slip is very high, so it is better not to choose a similar type of transmission.

The homemade cutting machine is also supplied with a vice that does not allow the material to exit from the cutting axis.

Bending and cutting of reinforcement

As a knife at home, most often choose either a carbide disc or an abrasive wheel. The type of the device depends on the feed of the tool.

It can have a front, bottom or pendulum feed.

The principle of assembly is very similar to the construction for bending. So, the machine for cutting the reinforcement starts to do from the frame, which in turn is assembled from metal corners.

To the received base it is necessary to attach the channel, which will play the role of the axis guide, and all the other parts are attached to it.

Only for the engine an additional reinforced pipe is needed.

Bearings, which are needed to support and drive the mechanism, are fixed to the upper frame, and the shaft and the motor are fastened with bolts.

In addition, where the disk will be fastened( also with bolts), you need to take care of the protective housing, because when you come into contact with metal, a spark will arise.

It is better to check the work on the machine at idle and using soft metals. Only then, if everything is working properly, you can check the installation in full force.

The main thing is that the distance from the bending shaft and the disc is at least 40 centimeters.
