The arc plate supports the main body of the product to ensure that the main body of the product will not move during the processing, and then is arranged on the mounting plate.

[0047] The benefit of adopting the above technical solution is that the limiting plate 73 fixes the position of the product, and then during the mold closing process, the product is cut to the required length through the cooperation of the cutting knife 71 and the cutting insert 72, which is convenient for subsequent use.

[0048] In some embodiments, a product positioning groove is provided at the bottom punching position 8, and bottom punching punches 81 are symmetrically arranged on the side surface of the product positioning groove. The bottom punching punches 81 are arranged side by side. One punch performs bottom punching, and the other punches a bottom notch. The two punches move together. The bottom punching punch 81 is connected to a bottom connecting block 82, and a pressing block is arranged in the upper die 2 to drive the bottom connecting block 82 to move.

[0049] The bottom punching position 8 is used to punch the bottom of the product. The punching position is accurate. After the mold is closed, it is automatically completed by driving with the pressing block to ensure the quality of the bottom punching.

[0050] In some embodiments, a supporting round tube is further arranged on the side surface of the product positioning groove. The end of the supporting round tube extends into the product. The other end of the supporting round tube is connected to a moving block. The moving block drives the supporting round tube to move towards or away from the product positioning groove.

The clamping claws 91 are arranged on the moving plate 94 through a support plate 96 and are driven to open and close by a cylinder. A guide rail and a slider are arranged on the lower side of the moving plate 94 to ensure the moving direction of the moving plate 94 and smooth movement. The second-direction moving assembly 93 includes a driving member 95 to drive the moving plate 94 to move along a direction perpendicular to the first direction. The second moving assembly includes a translation plate, and the translation plate is driven by the driving member 95. The driving member 95 is a cylinder. A lifting cylinder is further arranged on the lower side of the second-direction moving assembly 93 to control the lifting of the clamping claws 91.

[0054] The benefit of adopting the above technical solution is that the first direction moving component 92 drives the moving plate 94 to move along the first direction, so that the clamping claw 91 approaches the product and clamps the product, and the second direction moving component 93 drives the clamping claw 91 to clamp the product and transfer the product to the next workstation. At the same time, the first moving direction component moves outward after the product is placed, reserving sufficient space for mold closing, completing the continuous transfer of the product, and improving processing efficiency.

[0055] During the working process, the product is first loaded onto the loading vibration plate 1, and enters the receiving position 4 through the loading flow channel. The lifting plate 43 is lifted, and the clamping claw 91 clamps the product and places the product at the middle punching position 5. The mold is closed to complete the middle hole processing. At this time, the receiving position 4 continues to load, and the clamping claw 91 continues to transfer the product. At the same time, it clamps the product to be processed and the product that has completed the middle hole processing, and moves to the next station to complete flattening, fine cutting, and bottom punching in sequence. After each processing is completed, it moves down one station, and at the same time, the loading vibration plate 1 continuously loads the product, and the product is continuously processed in the mold until the product is unloaded after the processing is completed, thereby improving the processing efficiency, ensuring the processing quality, and reducing the processing cost.
