When the limiting wheel approaches the mating wheel, the pin of the limiting wheel can be inserted into the socket on the mating wheel accordingly, so that the limiting wheel and the mating wheel are connected, which can prevent the rotating shaft from continuing to rotate, and play a limiting role on the rotating shaft, thereby preventing the inertia generated after the drive motor stops from causing the rotating shaft to continue to rotate, thereby improving the accuracy of punching. In addition, when the pin is inserted into the corresponding socket, the lubricating oil in the cavity can enter the inner ring of the mating wheel through the leakage hole of the pin. Since the mating wheel is sleeved on the outer ring of the rotating shaft, the lubricating oil will enter the outer ring of the rotating shaft through the socket, completing the lubrication operation, reducing labor, and at the same time increasing the rotation smoothness and service life of the rotating shaft.

[0015] 2. Start the drive motor, which drives the rotating shaft via the connecting belt. This rotation of the shaft also drives the worm gear, which engages with the worm, causing the worm to extend downward and drive the corresponding punch downward to punch the material. Since two worm gears are provided, both punches can be driven downward simultaneously, improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The two guide rail fixing seats 8 are both provided with grooves on the side close to the mold opening 3, and punches 9 are provided in the two grooves. Vertical guide rails 16 are fixed on both sides of the grooves, and the punches 9 slide between the corresponding two vertical guide rails 16.

[0023] A fixed shaft sleeve 7 is provided above the two guide rail fixing seats 8, and a rotating shaft is rotatably provided inside the fixed shaft sleeve 7. Both ends of the rotating shaft extend out of the fixed shaft sleeve 7, and the outer ring of one of the extended ends is provided with a rotating wheel 6. Support legs 2 are fixed on both sides of the bottom end of the workbench 1, and a driving motor 5 is fixed on the top of the stand 4. A driving shaft is provided on one side of the driving motor 5, and the outer ring of the driving shaft is matched with a driving wheel. A belt is connected between the driving wheel and the rotating wheel 6.

[0024] The punch 9 can slide up and down between the corresponding two vertical guide rails 16. When the material to be punched is placed in the die opening 3, the punch 9 is used to punch the material. The function of the fixed sleeve 7 is to protect the rotating shaft.

[0025] Two protective shells 10 are connected to the outside of the fixed sleeve 7. The two protective shells 10 correspond to the positions of the two punches 9 respectively. A worm gear is provided inside the two protective shells 10. The worm gear is sleeved on the outer ring of the rotating shaft. The bottom ends of the two protective shells 10 are provided with a sliding opening. A worm 11 is slidably provided in each sliding opening. The worm 11 meshes with the corresponding worm gear. The bottom end of the worm 11 is connected to the top of the corresponding punch 9. The fixed sleeve 7 is fixed to the stand 4. The two punches 9 correspond to the positions of the die opening 3 respectively. The other end of the rotating shaft extends out of the fixed sleeve 7, and the extended end is rotatably connected to the stand 17. The stand 4 is connected to a support seat for supporting the other end of the fixed sleeve 7.

[0026] In actual operation of the present invention, the drive motor 5 is started, and the drive motor 5 drives the rotating shaft to rotate via the connecting belt. The rotating shaft rotates and the worm gear rotates. The worm gear and the worm 11 engage, thereby extending the worm 11 downward and driving the corresponding punch 9 to press downward to achieve the punching process of the material. Since two worm gears are provided, the two punches 9 can be driven to press downward at the same time, thereby improving production efficiency.

[0027] A vertical plate 17 is fixed on one side of the short side of the workbench 1, and a connecting frame 12 is fixedly connected to one side of the vertical plate 17. The connecting frame 12 is rotatably connected to the side close to the vertical frame 4 with a rotating rod 13. A plurality of L-shaped frames 14 are fixed on the outer ring of the rotating rod 13, and a limiting wheel 15 is fixed on the top of the plurality of L-shaped frames 14. The outer ring of the limiting wheel 15 is fixed with a plug post 20, and a leakage hole is provided at the bottom end of the plug post 20. The outer ring of the protruding end at the other end of the rotating shaft is provided with a mating wheel 18, and the mating wheel 18 and the limiting wheel 15 are meshed. A layer of anti-wear pad is fixed to the outer ring of the mating wheel 18 and the limiting wheel 15. A plurality of sockets 19 are provided on the outer ring of the mating wheel 18, and the plug post 20 is inserted into the corresponding socket 19. A cavity is provided inside the limiting wheel 15, and the cavity is filled with lubricating oil, and the cavity and the leakage hole are connected.

[0028] In the actual operation of the present invention, one end of the rotating rod 13 extends out of the connecting frame 12, and can be specifically connected to a motor. The motor drives the rotating rod 13 to rotate, so that the rotating rod 13 drives the L-shaped frame 14 to rotate, and makes the limiting wheel 15 approach or move away from the matching wheel 18. When the limiting wheel 15 approaches the matching wheel 18, the plug post 20 of the limiting wheel 15 can be correspondingly inserted into the socket 19 on the matching wheel 18, so that the limiting wheel 15 and the matching wheel 18 are connected, which can prevent the rotating shaft from continuing to rotate, and play a limiting role on the rotating shaft, thereby avoiding the inertia generated after the driving motor 5 stops causing the rotating shaft to continue to rotate, thereby improving the accuracy of punching.

[0029] In addition, when the pin 20 is inserted into the corresponding socket 19, the lubricating oil in the cavity can enter the inner ring of the mating wheel 18 through the leakage hole of the pin 20. Since the mating wheel 18 is sleeved on the outer ring of the rotating shaft, the lubricating oil will enter the outer ring of the rotating shaft through the socket 19, completing the lubrication operation, reducing labor, and at the same time increasing the rotation smoothness and service life of the rotating shaft.
