Punching machine tool sliding block

The invention belongs to the technical field of punching machine tools, and particularly relates to a punching machine tool sliding block which comprises a punching machine sliding block body, a plane base and two side edge guide rails, first connecting through grooves are formed in the outer walls of the two sides of the plane base, and L-shaped plates are movably connected to the groove walls of the first connecting through grooves; a plurality of connecting grooves are formed in the outer walls of the two L-shaped plates, and fixing mechanisms are connected to the groove walls of the connecting grooves. According to the stamping sliding block, the abrasion speed of the side guide rail in the stamping sliding block can be effectively reduced, stable work of the stamping sliding block is guaranteed, then the machining reliability of a stamping machine tool is guaranteed, the side guide rail of the stamping sliding block does not need to be integrally replaced, the use cost of the stamping sliding block is re
