Because the pressure sensor 702 is electrically connected to the second cylinder 704 through the controller, the controller that receives the signal controls the second cylinder 704. When the second cylinder 704 is running, the output shaft of the second cylinder 704 in the running state drives the "T"-shaped slider 707 to move outward along the trajectory of the "T"-shaped slide groove 7010, and the "T"-shaped slider 707 in the moving state drives the movable frame 705 to move outward, so that the movable frame 705 in the moving state drives the clamped workpiece to be stamped to move, and the upper mold 6 in the second descending state cooperates with the lower mold 4 to stamp another part of the workpiece to be stamped, and then the stamping of the workpiece to be stamped is completed in sections, which can avoid the operator manually moving the position of the stamped workpiece, which may easily cause accidental injury, and effectively improve the stamping efficiency of the device for the workpiece to be stamped.
