Bar bending on machine : what is it : how machine works : how to operate machine #civilengineering

Steel pieces that are often used as part of the inner structure of concrete are referred to as rebar by construction experts. Rebar can also be used for various other purposes.

It is a long piece of steel shaped like a stick or rod. It is often required to bent for different structural reasons. To bend the rebar, we have several options available.

In this article, we will discuss automatic bar bending machines. Rebar is also termed sometimes as a bar. In this article, we have used both terms.
A bar bending machine is a type of engineering steel bar processing equipment that is simple to operate and has good performance and reliability. It is mainly composed of transmission parts, stands, enclosures, and electrical appliances.

It is capable of bending steel bars from 0 to 180 degrees and is widely used in the construction of roads, bridges, tunnels, and other giant projects. The machine comes in both automatic and manual versions
The bar bending machine consists of an electric motor, a coupling, a circular plate, a worm gear drive, and an extended shaft. An electric motor transmits power to a gearbox, which decreases speed and increases torque.

A circular plate bends the bar using this gearbox. It can usually bend bars in the range of 6 mm to 16 mm. The auto reverse and auto forward mechanism is also powered by an electrical system that consists of a contactor and limit switch. The bar can be readjusted due to the spring back effect.

A bar bending machine is made up of the following parts, that are visible to its user:

Moving bending roller (This roller basically pushes the bar in the bending direction. It has normally diameter less than the central roller. It rotates around the central roller)
Center roller (This is the roller, around which the bar rotates. It itself remains stationary. It is usually made of aluminum or steel with a very high strength grade. Usually, its surface is also lubricated to aid in the bar bending process)
Adjustable stopper
Pilot lamp (This light lamp indicates that power is being supplied to the machine)
Main switch
Angle setter (dial type or there is a circular disc with holes all around its circumference. You can either set the angle by a dial or put a pin in the respective hole. Note that each hole usually represents an angle. Normally there is the only option available for the angle setter)
Operation button On/Off
Angle stopper (Left & Right)
Emergency stop button

Plug-in for foot switch or some other switching on mechanism.
Roller set
Foot Operated Switch (Usually it is a button which when pushed by your feet starts the machine’s operation).
