Punching die with fixing mechanism

The punching die with the fixing mechanism comprises a base, side plates are arranged on one side of the upper end of the base, the side plates are symmetrically arranged about the central axis of the base, a transverse plate is welded to the upper ends of the side plates, and an electric air cylinder is fixedly installed on the outer wall of one side of each side plate. Under the action of the sleeve plate, the rubber block, the movable plate, the protection baffle and the through hole, when the device drives the punching head to conduct punching, the movable plate abuts against the rubber block, elastic force is provided under the elastic action of the rubber block, the protection baffle blocks the punching head, and then the risk caused by the fact that people accidentally touch the punching head is prevented; according to the device, the effect of good safety protection capacity is achieved, meanwhile, the punching head can be effectively protected, the service life of the punching head is prolonged, unde
