Stamping protection device for machining

The invention belongs to the technical field of machining, and particularly relates to a stamping protection device for machining. The stamping protection device aims at solving the problems that in the machining process, disintegrating slag generated by stamping and forging splashes, dangers are likely to occur and the safety performance is not high. The stamping protection device comprises a base, the top end of the base is connected with a shell through bolts, the top end of the interior of the shell is connected with a supporting piece through a bearing, the side face of the supporting piece is connected with a partition plate through a screw, the bottom end of the partition plate is connected with an inserting rail through a bolt, and three fixing pieces are inserted into the inserting rail. According to the punching protection device, when the punching machine conducts impact forging on a blank, a stepping motor unfolds the partition plate through the supporting piece to form a guard bar, the impact are
