Punching device for production of guide sliding shoes of coal mining machine

The invention belongs to the technical field of metal stamping, and particularly relates to a punching device for production of a guide sliding shoe of a coal mining machine, which comprises a base, a limiting sliding mechanism, a mechanical positioning mechanism, a supporting and fixing mechanism, a middle bearing mechanism, two groups of punching and forming mechanisms, two groups of deburring mechanisms, a processing feedback regulation and control mechanism and a PLC (Programmable Logic Controller). The guide sliding shoe to be punched can be rapidly and accurately fixed and positioned, it is ensured that the position of the guide sliding shoe at a punching station is accurate, the punching strength and the positioning and clamping strength on the guide sliding shoe can be automatically determined according to the thickness of a part to be punched, the situation that the guide sliding shoe deforms or cracks due to the fact that the punching strength is too large is avoided, and the punching efficiency is
