[0028] The working principle of the present invention is as follows: the movable die assembly 10 is fixed on the telescopic rod of the die cylinder 8 by a fixing mechanism, which is convenient for maintenance and disassembly. Specifically, the fixed seat 2 17 cooperates with the fixed seat 1 16, and the motor 12 is controlled to work. Under the gear transmission, the ring gear 14 rotates, and then the fixed gear 18 and the eccentric wheel 19 rotate. The eccentric wheel 19 acts on the spherical end of the fixed shaft 20 to make the fixed shaft 20 slide radially, and then the fixed shaft 20 toward one end of the fixed seat 16 cooperates with the fixing holes on the fixed seat 16 and the fixed seat 2 17 at the same time to fix the fixed seat 2 17 and the movable die assembly 10. Further, the electromagnetic sliding shaft 15 moves and cooperates with the matching ring 1401 to fix the ring gear 14, so that the fixed state is more stable.

[0029] During operation, the material is transferred from the die platform 2, and the movable die set 10 is controlled to move up and down by the die cylinder 8. The product is punched out from the material by the die of the movable die set 10, and the product is adsorbed and carried upward. The collection slide 22 is controlled by the collection control electric cylinder 23 to move to the bottom of the movable die set 10, and the product falls onto the collection slide 22 for collection. When the movable die set 10 is moved up and down, the guide column 1001 cooperates with the guide cylinder 29, and the guide cylinder 29 plays a guiding role. Protective oil is applied inside the guide cylinder 29 to play a protective and lubricating role. After a long period of relative cooperation, the oil should be replaced. Specifically, the cleaning motor 24 works, the cleaning screw 26 rotates, and the cleaning slide 25 moves, and extends to the inside of the guide cylinder 29 through the cleaning cylinder 28. The driving motor 27 drives the cleaning cylinder 28 to perform the cleaning operation, eliminating the tedious internal cleaning operation by manual labor. Unused oil can be transferred through the transmission box 30 to complete the cleaning and maintenance operations.

[0030] After the product is punched out from the material, the residual material is transported to the bottom of the cutting cylinder 9, and the cutting part 31 is controlled to rise and fall by the cutting cylinder 9 to cut the residual material. Specifically, the residual material is arranged, and the free end of the residual material is located on the support frame 3302, that is, it is supported by the support frame 3302. Further, the stabilizing pressure plate 36 is controlled by the stabilizing electric cylinder 35 to fix the side of the residual material to prevent it from jumping during cutting.

[0031] Furthermore, after the cutting is completed, the cutting part 31 moves upward, and the push wheel 32 pushes the pushing part 3301, so that the supporting slide 33 and the supporting frame 3302 move in the direction away from the side of the residual material. At the same time, the lifting electric cylinder 38 controls the limit platform 41 to move to the bottom of the residual material to support the residual material, and the residual material has two arc-shaped notches, which are limited by the limit platform 41. Under continuous operation, the cut residual materials are stacked together, and then the motor 3 works to rotate the screw rod 4 and slide the transfer table 37 to transfer the residual material. The stacked residual material is located between the support table 6 and the fixed plate 7, and the fixed electric cylinder 5 controls the fixed plate 7 to fix the residual material for manual sorting.
