Introduction to Rebar Processing Machinery

Rebar processing machinery is to process the wire rod steel and straight rebar into the length size, bending shape or installation components required for the installation and construction of reinforcement engineering, mainly including strengthening, straightening, bending hoop, cutting, bending, component forming and rebar connection and other equipment. The rebar components include reinforcement cage, steel bar truss (such as triangular beam, wall panel, column, girder), reinforcing mesh.

As the skeleton of concrete, rebar constitutes the reinforced concrete, which has become the main material used widely in building structure. Before pouring concrete, the rebar must be made into a framework of certain specification and form and included in the formwork. In order to make the reinforcement framework, it is necessary to strengthen, stretch, straighten, cut, bend and connect the reinforcement before binding. Due to the large amount of rebar, it is difficult to complete by manual operation, so it is necessary to use various special machines for processing. This kind of machinery is called rebar processing machinery, which is called rebar machinery for short.

There are many kinds of rebar processing machinery, which can be divided into four categories according to the processing technology: strengthening, forming, welding and prestressing.

1. Rebar strengthening machinery: mainly including rebar cold-drawing machine, rebar cold-extruding machine, rebar cold rolling and twisting machine, cold rolling ribbed rebar forming machine. Its processing principle is to apply force beyond its yield point to the rebar to produce different forms of deformation, so as to improve the strength and hardness of rebar and reduce plastic deformation.

2. Rebar forming machinery: rebar straightening and cutting machine, rebar cutting machine, rebar bending machine, rebar mesh forming machine, etc. Their functions are processing and shaping the raw material rebar and the rebar framework required for the installation of various concrete structures.

3. Rebar welding machinery: mainly including rebar welding machine, rebar spot welding machine, rebar mesh forming machine, rebar electroslag pressure welding machine, which are used for welding in rebar forming.

4. Rebar prestressed machinery: mainly including stretching machine and button head machine composed of Electric oil pump and jack, which are used for prestressed rebar tensioning work.
