As time accumulates, the protective covers of various motors and pumps are corroded and damaged. In order to form a better man-machine isolation for various operating equipment and prevent personnel from being involved in the equipment and causing personal injury, it is necessary to replace the damaged protective covers. However, the operating equipment such as motors and pumps in the company is small in size, and the matching protective covers are also small in size. The company's existing plate rolling machines are mostly hydraulic three-roller plate rolling machines with a plate rolling thickness of 3mm-20mm, a plate rolling width of less than 2000mm, and a full-load minimum diameter of more than 300mm. The protective covers of various motors and pumps are small in size, and the full-load minimum diameter is basically within 100mm-300mm during production. Therefore, large hydraulic plate rolling machines cannot be used in the production process of protective cover arc plates. If the traditional knocking method is used to process the arc steel plate protective cover, the efficiency is low and the labor intensity is high. Utility Model Content
