[0025] Embodiment 3: According to Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, a bottom groove 24 is provided in the middle of the lower end of the connector 2, and the bottom groove 24 is connected to the punching groove 7. Sealing plates 8 are rotatably connected to both sides of the middle of the bottom groove 24. Inner cavities 17 are provided inside the two sealing plates 8, and magnetic strips 19 are fixedly connected inside the inner cavities 17. An end notch 16 is provided at the upper end of the sealing plate 8, and a metal plate 18 is fixedly connected inside the end notch 16. An inner card slot 25 is provided at the upper end of the bottom groove 24, and a magnetic ring 20 is fixedly connected inside the inner card slot 25. One side of the inner part of the middle carrier 21 is provided. A fastening slot 29 is provided, which is connected to the connecting pipe 22. A clamping groove 30 is opened at the outer edge of one side of the fastening slot 29. A fastening frame 27 is clamped inside the fastening slot 29. An extension clamp ring 28 is fixedly connected to the outer edge of one side of the fastening frame 27. A blocking cloth 26 is provided on the side of the fastening slot 29 close to the connecting pipe 22. The blocking cloth 26 is fixedly connected to the middle carrier 21 by extrusion of the fastening frame 27. The sealing plate 8 is made of plastic to reduce weight and ensure that the metal plate 18 can be adsorbed by the magnetic ring 20.

[0026] In the present invention, the sealing plate 8 and the magnetic ring 20 are arranged to seal the lower end of the punching groove 7 when in use. When the blank is adsorbed, the suction force can be concentrated below the blank to ensure the stability of the adsorption. At the same time, through the adsorption of the airflow, the waste material dropped by the punching can also fall quickly and will not be stuck on the punching die. Therefore, there is no need to set up a feeding mechanism, which reduces the overall cost. In addition, this method has a low maintenance cost and is also more convenient to disassemble.

[0027] The method of use and working principle of the device: when in use, the punching body 1 and the connecting body 2 are installed on the punching equipment and used as the lower die seat. A waste collection box can be set below the punching groove 7 to collect the waste generated by the punching. Then the blank is placed in the slot and the air pump is started at the same time to make the vent hole 6 and the punching groove 7 spray gas. The gas exerts force on the blank to facilitate the movement of the blank, thereby facilitating the placement of the blank in the slot and positioning. Then the air pump is controlled to make the punching groove 7 and the vent hole 6 inhale gas to absorb the blank. Then the upper die seat is punched to deform the blank. The waste generated by the punching enters the punching groove 7 and is absorbed by negative pressure to separate it from the upper die seat to prevent the waste from being stuck on the upper die seat. The blocking cloth 26 and the fastening frame 27 are used to block it. , to prevent waste from entering the connecting pipe 22, the air pump stops working, and the waste falls on the two sealing plates 8 with gravity for processing and use. The processed workpiece is subsequently processed into automotive parts. When the weight of the waste on the sealing plate 8 is greater than the suction force between the magnetic strip 19 and the magnetic ring 20, the two sealing plates 8 are opened, and the waste falls. Through the attraction between the two magnetic strips 19, one end of the two sealing plates 8 is gradually approached. At this time, the two sealing plates 8 are in an inclined state, and the two magnetic strips 19 are adsorbed by the magnetic force of the magnetic ring 20. At this time, the two sealing plates 8 are closed. When the waste is stuck in the punching groove 7, the blank can be adsorbed by the vent hole 6, and the punching groove 7 sprays gas. At this time, the air pressure in the punching groove 7 increases, and the sealing plate 8 is pushed open to remove the waste.
