[0002] At present, the steel bar straightening is processed by a straightening machine. The rolled steel bars are placed at the entrance side of the straightening machine. After straightening, the rolled steel bars become straight steel bars. The existing steel bar straightening machines have the following disadvantages:

[0003] Before straightening, the steel bars are wound in circles to form a bundle structure. When straightening, take a bundle of steel bars, find the active end of the steel bars, and convey them to the straightening machine for straightening while unwinding the wires. The steel bars quickly change from curved to straight. However, since the steel bars are too curved when they are wound into coils, the surface will crack after straightening directly, and sometimes the machine will get stuck. This is a shortcoming of the existing technology. Utility Model Content
