[0026] The first sliding groove 11 is formed in the inner side wall of the punching frame 10. One side of the first sliding block 12 is slidably connected to the inside of the first sliding groove 11. One side of the U-shaped frame 13 is fixedly connected to one side of the first sliding block 12. The bottom of the U-shaped frame 13 is fixedly connected to the top of the first cutting tool 15. The outer side wall of the second cylinder 17 is fixedly connected to the inner side wall of the mounting frame 16. The piston rod of the second cylinder 17 is fixedly connected to the top of the second cutting tool 18.

[0027] In one embodiment, the outer side wall of the first cylinder 14 is fixedly connected to the top of the punching frame 10. The piston rod of the first cylinder 14 is fixedly connected to the top of the U-shaped frame 13. The bottom of the mounting frame 16 is fixedly connected to the top of the U-shaped frame 13. When punching a square rubber product, place the square rubber product on the placing table 27. Control the first cylinder 14 to drive the U-shaped frame 13 to move downward. The U-shaped frame 13 drives the first cutting tool 15 to move downward, so that the first cutting tool 15 punches the square rubber product. When punching a circular rubber product, control the second cylinder 17 to drive the second cutting tool 18 to move downward until the second cutting tool 18 moves to a position lower than the first cutting tool 15. Then control the first cylinder 14 to drive the U-shaped frame 13 to move downward. The U-shaped frame 13 drives the second cylinder 17 to move downward, so that the second cutting tool 18 moves downward. When the second cutting tool 18 penetrates the product, drive the turntable 25 to rotate by the rotating motor 24, so as to trim the circular rubber product. Through the arrangement of the first sliding groove 11 and the first sliding block 12, it plays an accurate guiding role for the U-shaped frame 13, thus avoiding the deviation of the positions of the first cutting tool 15 and the second cutting tool 18 and improving the punching accuracy.

[0028] In one embodiment, the adjusting assembly 201 includes three second chutes 20, second sliders 21, a lead screw 22, a driving motor 23, a rotating motor 24, a turntable 25, a suction cup 26, and a placement table 27; the bottom of the punching frame 10 is fixedly connected to the top of the second slider 21, three second chutes 20 are formed in the top of the workbench 30, the bottom of the second slider 21 is slidably connected to the inside of the second chute 20, the outer wall of the driving motor 23 is fixedly connected to one side of the workbench 30, the output end of the driving motor 23 is fixedly connected to one end of the lead screw 22, the other end of the lead screw 22 is rotatably connected to the inner wall of one second chute 20, the outer wall of the lead screw 22 is threadedly connected to the inside of one second chute 20, the bottom of the placement table 27 is mounted on the top of the workbench 30, the outer wall of the turntable 25 is rotatably connected to the inside of the placement table 27, the outer wall of the rotating motor 24 is fixedly connected to the inner wall of the workbench 30, the output end of the rotating motor 24 is fixedly connected to the bottom of the turntable 25, the bottom of the suction cup 26 is mounted on the top of the turntable 25. By controlling the driving motor 23 to drive the lead screw 22 to rotate, the lead screw 22 drives the second slider 21 to move in the second chute 20, so that the second slider 21 drives the punching frame 10 to move. Thus, by adjusting the position of the punching frame 10, flash punching can be performed on circular rubber products of different sizes, expanding the application range of the device and improving work efficiency.

[0029] In one embodiment, a collection box 31 is installed on one side of the workbench 30. Through the setting of the collection box 31, the waste generated by the punching operation can be stored and collected, avoiding pollution of the external environment and facilitating subsequent cleaning or recycling.

[0030] When the utility model is in operation: The cost reduction device is placed at a designated position. When it is necessary to punch a square rubber product, the square rubber product is placed on the placement table 27. Through the setting of the suction cup 26, the product can be fixed. Control the driving motor 23 to drive the lead screw 22 to rotate. The lead screw 22 drives the second slider 21 to move in the second chute 20, so that the second slider 21 drives the punching frame 10 to move. Thus, by adjusting the position of the punching frame 10, the flash punching operation can be carried out on square rubber products of different sizes. Then control the first cylinder 14 to drive the U-shaped frame 13 to move downward. The U-shaped frame 13 drives the first cutter 15 to move downward, so that the first cutter 15 punches the square rubber product; When it is necessary to punch a circular rubber product, the circular rubber product is placed on the turntable 25. Control the suction cup 26 to work to adsorb the circular rubber product on the turntable 25. Control the second cylinder 17 to drive the second cutter 18 to move downward, so that the second cutter 18 moves to a position lower than the first cutter 15. Control the driving motor 23 to drive the lead screw 22 to rotate. The lead screw 22 drives the second slider 21 to move in the second chute 20, so that the second slider 21 drives the punching frame 10 to move. Thus, by adjusting the position of the punching frame 10, the flash punching operation can be carried out on circular rubber products of different sizes. Then control the first cylinder 14 to drive the U-shaped frame 13 to move downward. The U-shaped frame 13 drives the second cylinder 17 to move downward, so that the second cutter 18 moves downward. When the second cutter 18 penetrates the product, drive the turntable 25 to rotate through the rotating motor 24, so as to trim the circular rubber product. The collection box 31 stores the waste generated after punching, avoiding polluting the external environment and facilitating subsequent centralized cleaning or recycling.
