There are many types of steel bar processing machines, which can be divided into four categories: strengthening, forming, welding, and prestressing according to their processing technology:

1. Rebar strengthening machinery: mainly includes steel bar cold drawing machine, steel bar cold drawing machine, steel bar cold rolling and twisting machine, cold rolled ribbed steel bar forming machine, etc. The processing principle is to apply different forms of deformation to the steel bar by applying a force exceeding its yield point, thereby increasing the strength and hardness of the steel bar and reducing plastic deformation.

2. Rebar forming machinery: rebar straightening and cutting machine, rebar cutting machine, rebar bending machine, rebar mesh forming machine, etc. Their function is to process the raw steel reinforcement and the requirements of the reinforcement skeleton required for the installation of various concrete structures.

3. Rebar welding machines: mainly include rebar welding machines, rebar spot welding machines, rebar mesh forming machines, rebar electroslag pressure welding machines, etc., used for welding in rebar forming.

4. Reinforced steel prestressing machinery: mainly consists of electric oil pumps and jacks and other stretching machines and heading machines, which are used for steel prestressing operations.
