[0002] In electrical engineering, copper busbars are an important conductive material and are widely used in electrical equipment such as distribution cabinets and switch cabinets. The processing quality of copper busbars directly affects the performance and safety of electrical equipment. In order to improve the conductivity and appearance quality of copper busbars, they are usually polished and brushed. Polishing is to remove the oxide layer and burrs on the surface of the copper busbar, while brushing can increase the roughness of the copper busbar surface, thereby improving its bonding strength with the insulating material.

[0003] However, the existing copper bar processing equipment has some shortcomings when performing grinding and wire drawing operations. First, since the copper bar itself has a certain hardness and toughness, the traditional manual grinding method is inefficient and it is difficult to ensure the uniformity and consistency of grinding. Secondly, the copper bar is prone to bending and deformation during the processing process, resulting in the copper bar after processing unable to meet the precise size and shape requirements. In addition, the existing wire drawing equipment is often complex in structure, inconvenient to operate, and the wire drawing effect on the copper bar is not ideal, which is easy to cause damage to the surface of the copper bar.
