The punching plate 300 is arranged in the upper die 30, the die core 31 is provided with an avoidance hole 310 for avoiding the punching plate 300, the avoidance hole 310 can accommodate the punching plate 300 on the one hand, and can conveniently punch materials (waste materials) to fall on the other hand, so that the punched materials falling on the workpiece 2 are concentrated on the workbench 1 or the lower die 32, and the cleaning is convenient. During punching, the upper die 30 and the lower die 32 are assembled, the punching plate 300 punches a hole on the outer wall of the workpiece 2 and enters the avoidance hole 310, and after one-time punching is completed, the upper die 30 drives the punching plate 300 to reset, so that one-time punching is completed, and the next punching is waited. After resetting, the rotating component 4 tightly pushes the workpiece 2 sleeved on the mold core 31, and then rotates a preset angle, so that the workpiece 2 can rotate on the mold core 31, and then the next punching process is performed, so that the circulation is performed, the outer wall of the workpiece 2 is automatically punched for multiple times, and a shutter-shaped punched hole is formed. It should be further noted that, in order to enable the rotating component 4 to tightly push the workpiece 2, when the workpiece 2 is placed on the mold core 31, the tail portion of the workpiece 2 extends outwards from the mold core 31, so that a reserved portion of the workpiece 2 and the rotating component 4 act.
