The second fixed plate 17 can drive the punching assembly to move downward. During the downward movement of the guide plate 23, the inclined surface on it can contact the roller 25 and cause the roller 25 to roll. Under the action of the inclined surface, the roller 25 can squeeze the mounting bracket 26, causing the lower end of the mounting bracket 26 to deflect to the right and squeeze the contact of the sensor 24. When the contact of the sensor 24 triggers the sensor 24, the sensor 24 transmits a stop and reverse signal to the external controller. , the external controller controls the servo motor 6 to stop for a certain period of time and reverse, so that the second fixed plate 17 moves upward, and at the same time the inclined surface gradually separates from the roller 25, so that the mounting frame 26 relaxes the pressure on the contact of the sensor 24, thereby resetting the sensor 24 and the second fixed plate 17. In the above process, when the servo motor 6 stops rotating, the external controller controls the telescopic end of the cylinder 28 to extend and drive the push plate 29 to move to the right, and the push plate 29 drives the guide rod 30 to slide in the vertical plate 27, and at the same time the push plate 29 drives the punching knife 33 to move; at the same time, when When the push plate 29 moves, the push plate 29 can drive the round rod 34 and the elastic plate 35 to move to the right, so that the elastic plate 35 presses the product. Under continuous force, the elastic plate 35 can undergo a certain elastic deformation, so that the punching knife 33 can penetrate the knife hole to punch the product. The scraps generated after the punching knife 33 punches the product can be discharged through the guide holes and the air-avoiding holes on the insert 38, and are connected to the external suction fan through the suction pipe 40. Under the suction force of the external suction fan, the scraps can be discharged through the suction pipe 40 and the suction sheet metal pipe 39.
