Manufacturing of a hand-held machine for bending reinforcement

The practice of recent years shows that a hand-held bending machine for reinforcement is very often used in the construction of objects for various purposes.

Modern construction technologies are designed to use high-quality materials and pre-assembled structures.

This approach allows you to perform work in a short time and with high quality. At the same time, almost every construction site requires special equipment to prepare non-standard products.

Most often such a need appears in the manufacture of non-standard reinforced concrete structures directly on the construction site.

Machine types

In order to build quickly and efficiently, two conditions must be met. The first is to use building materials of a new generation.

The second is to use efficient assembly and erection technologies.

Prefabricated reinforced concrete structures are used in the construction of multi-storey residential buildings, industrial buildings and structures for many decades.

The strength of concrete elements will come from metal reinforcement, which is laid inside the product during manufacture.

Metal in combination with concrete ensures proper strength and durability of the structure.

In the manufacture of many building elements, tools for forming reinforcing bars are required.

Measuring rods of metal fittings are used only for the construction of large-scale objects.

Individual housing construction, construction of auxiliary buildings such as a garage or a sauna, require cutting, bending and other changes in the original shape of the rod.

Given the high strength of the reinforcement, without tools and special devices in such cases is indispensable. The photo shows a machine designed for bending the rod.

The machine is factory-made. Such a device is of great value and it is not profitable to use it on small objects.

As a rule, such machines are installed in shops for the production of reinforced concrete products.

Today, the armature of composite materials appeared on the market. Its technical characteristics are not worse than those of a metal one.

In this case, it has one significant drawback - it can not be deformed and give it a different form from a straight line.

For this reason, its use in the construction of individual houses is limited. While metal fittings can be bent by hand.

Such a need arises in the arrangement of massive and complex foundations, as well as in the construction of walls.

It is much easier and more productive to do this with a special machine that is designed for bending fittings.

Machines for bending fittings

Currently, the market offers a wide range of machines for bending reinforcement of various diameters.

According to the principle of operation, the machines are divided into the following types:

  • hydraulic;
  • pneumatic;
  • manual;
  • electromechanical;
  • electromagnetic.

In order to perform operations on the bending of reinforcement in full accordance with the technical task, you must use a certain type of rigging.

Machines equipped with a hydraulic drive do not require that the worker bend the reinforcement bar with his own hands. This operation is performed automatically.

The most perfect are the units of electromechanical type.

The principle mechanism of operation of all machines is the same. The reinforcing bar is fixed between the thrust and the central shaft. A bending shaft is located on the outside of the reinforcement.

Under the influence of the bending shaft, the reinforcing bar is bent around the central shaft, the diameter of which can be changed depending on the profile of the workpiece.

In this case, the thrust shaft does not allow the remaining part of the workpiece to rotate. The larger the diameter of the reinforcement, the more energy you need to apply for bending.

The drawing of the simplest machine tool is shown in the picture.

Many individual builders and medium-sized construction companies prefer to use self-made machines for bending fittings.

Depending on its weight and scope, all machines for bending reinforcement can be divided into two main types:

  1. mobile;
  2. stationary.

For working on remote sites, laying roads and structures it is more convenient to use a mobile unit. A device weighing up to 100 kg is considered portable.

Stationary machines are installed in workshops and on conveyor lines. The industry produces devices with automatic control.

For large volumes of production, blanks of the same type are required."Bend" them more profitable and faster on stationary machines.

How to assemble a hand-held machine

A self-made machine for bending reinforcement can be assembled from improvised materials. First of all, you need to carefully study the drawing of this device.

It is very important to clearly understand the principle of operation and purpose of all elements - the central, supporting and bending shaft.

For greater accuracy and confidence, you can assemble a breadboard model on a wooden board using nails as the main elements.

After this, you can proceed to the next step - the selection of components and materials.

Completion

In the manufacture of the bending machine you will need:

  • a section of the channel;
  • metal corner;
  • bolts and nuts, which will be used for fixing the component elements.

Details must be selected, guided by the drawing. From them it is necessary to make the base, the lever and to fix on the base the central and bending shaft.

Assembling

The photo shows a bending machine for armatures, which is assembled by hand. The strength of the assembled structure should be higher than that of the reinforcement.

Bending machine

For the reliability test, the rod of different diameters should be "bent".As a result of testing, it is necessary to determine the limiting diameter of the reinforcement, which can be bent on the machine tool.

Rules for servicing and operating the

The manual machine, made by hand for the bending of the rod, in terms of design and functionality, does not differ from the factory production model.

For this reason, it is necessary to handle this equipment in accordance with the current regulations.

Before starting work, it is necessary to check the reliability of the fasteners. Movable elements should not have play.

Since the armature has to be formed by one's own hands, it is necessary to use work clothes and personal protective equipment during work.

The person who will perform operations on metal bending, it is necessary to teach the methods of work on the machine.

The workstation should be equipped in such a way that the initial blanks are fed from one side and the finished part is laid on the other.

Cluttering of the territory adjacent to the machine is not allowed.
