The steel bar mesh is widely used in bridge projects, tunnel projects, and construction projects, etc. However, during steel bar production or after being purchased externally and placed for a long time, the surface of the steel bars is prone to rusting, and there is still rust on the surface after being straightened. The rusty steel bars are directly used in bridge projects, tunnel projects, or construction projects, etc. after being formed by the forming device, which usually makes the bridge project, tunnel project, or construction project not meet the standard requirements. And it is usually difficult to remove rust from the steel bar mesh after forming because the distance between the steel bars is small after the steel bar mesh is welded and formed, and it is usually difficult to polish. When rust appears, it can only be polished manually. Therefore, it is necessary to remove rust from the steel bars, but the existing steel bar straightening machines do not have a rust removal function. Content of the Utility Model
