Description

[0002] In civil engineering, the processing of reinforcing bar is the key link in the construction process, especially the bending process of reinforcing bar. The traditional reinforcing bar bending mode depends on manual operation or simple mechanical equipment, which is not only low in efficiency, but also poor in operation safety.

[0003] In recent years, with the improvement of the requirements of building engineering on reinforcing bar processing precision and efficiency, the market demand for automatic and intelligent reinforcing bar bender is increasingly strong. However, in the prior art, many reinforcing bar benders still need to manually support the reinforcing bar to be bent during use. The current use method reduces the operation safety of the workers. Some devices are provided with a baffle at the tail end of the reinforcing bar to limit the tail part of the reinforcing bar. However, since the tail end of the reinforcing bar is displaced and the length is gradually shortened during bending, the baffle is difficult to adapt to the displacement of the tail part of the reinforcing bar during bending. Friction is easily generated between the reinforcing bar and the baffle, which reduces the service life of the equipment, causes wear on the surface of the reinforcing bar, and once the reinforcing bar is separated from the baffle, it is easy to cause harm to the operator, which has certain safety hazards and needs to be improved.
