What Is a Rebar Processing Machine?
Rebar Processing Machines are broadly classified into three types based on their functions: rebar cutters, rebar benders, and rebar welders. Each of these functions is important.
Rebar is a steel material, it is a steel bar for reinforced concrete. A Rebar Processing Machine is a machine tool to process this steel material, known as rebar at construction sites and factories.
Usage of Rebar Processing Machine
As the name suggests, Rebar Processing Machines are used for processing rebar. However, since rebar is generally a steel material used to reinforce concrete and other structures, the actual location where the machine is used must be taken into consideration regarding the use of the Rebar Processing Machine.
In the case of cutting, bending, and welding, the performance specifications of the machine tool required for mass production in a factory are different from those required for work on the construction site, and the requirements for the machine in terms of machine weight, transportation, fuel power, etc., and its usage are also different.
Principle of Rebar Processing Machine
Reinforced concrete, also called RC, is a material that is strong in the compressive direction but lacks tensile strength, which is compensated for by steel bars (which are strong in tensile strength).
Most of today’s reinforcing bars are not round steel but have knots and ribs in irregular shapes. This is because the unevenness of the knots and ribs enhances adhesion to the concrete and prevents the rebar from falling out.
Rebar Processing Machines are machines that cut, bend, and spot-weld these irregularly shaped steel materials.
The first is a cutting machine, but there is a Rebar Cutter as a Rebar Processing Machine used at construction sites. Most of them are handy and portable, and they cut reinforcing steel bars either electrically or hydraulically. However, they are not suitable for cutting large quantities of rebar and are intended for on-site use.
On the other hand, the Automatic Rebar Cutting Machine is used in rebar processing factories. There are many fully-automated types that are automated, and a series of processes such as carrying in, cutting, and discharging are performed at high speed under computer control. Processing accuracy can be achieved in mm units, and many of them are capable of processing multiple rebars at the same time.
The bending machine, like the cutting machine, includes a handy type known as a Rebar Bender. However, the Rebar Bender is not suitable for complex bending or handling large quantities.
In factories, Automatic Rebar Processing Machines that can handle complex bending of curves for multiple bars and in large quantities based on NC control, and stationary types called Ring Benders that are dedicated to circular bending are also often used.
Finally, there are welding machines, but various types of Rebar Processing Machines are used for spot welding applications rather than for rebar-exclusive use. For factories, there are also Spot Welding Processing Machines suitable for the rebar assembly method, which combine welding and rebar assembly processing in a single set.
