[0002] With the development of modern industry, market competition is becoming increasingly fierce, and various industries have put forward higher requirements for the production efficiency and processing accuracy of metal parts. In the case of large-scale production, the traditional manual punching method is extremely inefficient and cannot meet production needs. Therefore, a device that can achieve efficient and precise punching processing is needed to improve the production efficiency and quality of metal parts to meet the needs of large-scale and high-precision production in modern industry. After searching, the public (announcement) number: CN216911694U discloses a punching machine for metal parts processing. The punching machine for metal parts processing is convenient for moving the punching machine by setting a base and a pulley device. The control box and the recycling box are set to achieve the purpose of electrically controlling the punching machine and quickly collecting the waste generated by metal parts processing. An operating platform, a first pressure block, an arc-shaped clamp, a first buffer device, a second pressure block, a clamp and a second buffer device are arranged to achieve the purpose of clamping and fixing metal parts of different shapes and performing notching processing on metal parts, which greatly improves the notching processing efficiency of metal parts, improves the utilization rate of the notching machine, and enhances the practicality of the notching machine. However, there are shortcomings: when using an arc-shaped clamp or a clamp, the metal parts cannot be clamped synchronously, that is, the metal parts cannot be automatically centered, so it is easy for the metal parts to be placed in the wrong position during clamping, which may cause the position of the punching to be offset, and ultimately cause the metal parts after punching to be unqualified, wasting costs.

The overall process is that when positioning the metal parts, first bend the first rod body 4, the first rod body 4 will drive the connecting rod 6 and the bending rod 8 to move at the same time, and the bending rod 8 will drive the second rod body 5 on the other side to rotate, and the second rod body 5 will also drive the connecting rod 6 to move. At this time, the clamps 7 on both sides can be synchronized and self-centering to clamp, so that the metal parts can be positioned correctly, so that the punching position can be accurate during punching, which greatly improves the qualified rate of metal parts and avoids excessive waste of costs.

[0023] In this embodiment, the two sets of clamps 7 are provided with multiple sets of threaded holes 10, and there are slide grooves 11 running through the multiple sets of threaded holes 10. The multiple sets of threaded holes 10 are threadedly connected with corresponding first bolts 12, and the multiple sets of slide grooves 11 are slidably connected with blocks 13. By moving the block 13 on the slide groove 11 to adjust the clamp 7, the clamp 7 can be made into a V-shape or a flat shape so that it can clamp metal parts of various shapes. The two sets of first bolts 12 are threadedly connected to the corresponding blocks 13. A groove body 9 is provided on the first frame 2, and waste metal parts can be removed from the first frame 2 through the groove body 9. When it falls down, multiple groups of through holes are provided on the two groups of plate bodies 3, one group of through holes is slidably connected with a second bolt 14, and the second bolt 14 is threadedly connected to the first rod body 4.

[0024] The working principle of this embodiment: when in use, first place the metal part in the center of the clamp 7. According to the shape of the metal part, we pull out or pull back the block 13 on the clamp 7 through the slide groove 11 to adapt to metal parts of different shapes, and can tighten it by cooperating with the first bolt 12 and the threaded hole 10. Then bend the first rod body 4 so that it can simultaneously drive the connecting rod 6 and the bent rod 8 to move, thereby driving the second rod body 5 and the connecting rod 6 connected on the other side to also move synchronously, and then drive the clamps 7 connected on both sides to move closer to the center to perform self-centering clamping on the metal part, and then the hydraulic cylinder 20 drives the punch head 21 to punch the metal part. After punching is completed, the excess waste will fall out of the trough body 9 and the waste port 15 into the collection box 17 for collection.
