Further comprising: a hand-clipping prevention device 400; the anti-pinch device 400 comprises a protective plate 410, a normally closed switch contact rod 420, a spring 430, a normally closed switch 440 and a guide rod 450;

the through hole 411 matched with the outer peripheral wall of the lower die 152 is formed in the protection plate 410, the protection plate 410 penetrates through the lower die 152, and the protection plate 410 can move up and down freely relative to the lower die 152.

The bottom of the protection plate 410 is connected with a guide rod 450, the base 110 is provided with a guide hole 111 corresponding to the guide rod 450, and the lower end of the guide rod 450 is inserted into the guide hole 111 and can move up and down relative to the guide hole 111.

The guide bar 450 is sleeved with a spring 430 between the protection plate 410 and the base 110, and the upper end of the spring 430 is fixed on the protection plate 410 and the lower end thereof is fixed on the base 110.

A normally closed switch contact rod 420 is fixed on the circumferential edge of the protection plate 410, and a normally closed switch 440 fixed on the base 110 is correspondingly arranged below the normally closed switch contact rod 420; the normally closed switch 440 is connected in series to the power line of the linear driving device 200.

It should be noted that, in a normal state, the power line where the linear driving device 200 is located is in a closed power-on state, and when the protection plate 410 is pressed down to drive the normally closed switch contact rod 420 to press down and trigger the normally closed switch 440, the power line where the linear driving device 200 is located is disconnected, and the linear driving device 200 stops working.

Preferably, the linear driving device 200 is a hydraulic cylinder.

Prevent tong's novel punching machine in this embodiment use the principle as follows:

1. a worker places the raw material plate on the lower die 152, and the hydraulic cylinder works to drive the upper die 161 to press down to complete the punch forming operation;

2. if the worker fails to operate the raw material plates, the arm is not timely moved away from the lower die 152, and at this time, the arm first contacts the protection plate 410, so that the protection plate 410 is pressed down to drive the normally closed switch contact rod 420 to press down to trigger the normally closed switch 440, the power line where the straight hydraulic cylinder is located is disconnected, and the hydraulic cylinder stops working, thereby ensuring the safety of the worker in operation;

3. when the worker's arm is removed from the lower mold 152, the guard plate 410 is reset by the spring 430, the normally closed switch 440 is energized, and the hydraulic cylinder will operate normally.

Example two, refer to fig. 1-4.

After the punching machine works for a period of time, the punching machine generally needs to be maintained and maintained in a shutdown state; however, due to aging of the press, an operational error of a worker, or other reasons, a malfunction of the apparatus may occur, which may cause the upper mold to drop or press down suddenly, and may also cause a safety accident by causing a mistake to the worker.
