The snap-fit ​​rod 12 is fixedly connected to the bottom of the pressure block 1. The snap-fit ​​groove 13 is opened between the snap-fit ​​rod 12 and the push block 9. The push block 9 is fixedly connected to one end of the snap-fit ​​rod 12. A limiting mechanism is installed on the outside of the snap-fit ​​sleeve 4. The limiting mechanism includes a top rod 14, a clearance hole 15, a top plate 16 and a top spring 17. The top rod 14 is fixedly connected to one side of the limiting sleeve 5. The clearance hole 15 is opened on the top plate 16. The top plate 16 is rotatably installed on the outside of the snap-fit ​​sleeve 4. The top spring 17 is movably sleeved on the outside of the top rod 14. A collecting device is provided below the pressure block 1.

[0032] The collection device includes a base 18, a placement block 19, a leakage hole 20, a collection cart 21, a moving trough 22, moving wheels 23, and a handle 24. The placement block 19 is detachably mounted on the base 18. The leakage hole 20 is opened on the placement block 19. The moving trough 22 is opened inside the base 18. The moving wheels 23 are detachably mounted on the bottom of the collection cart 21 and move within the moving trough 22. The handle 24 is detachably mounted on one side of the collection cart 21.

[0033] A cylinder 25 is detachably mounted on one side of the base 18. A piston rod 26 is connected to the output end of the cylinder 25. A lower locking block 27 is provided at the other end of the piston rod 26. An upper locking block 28 is detachably mounted on one side of the collection vehicle 21.

[0036] In this embodiment, when the device is needed, the sheet material is first placed between the limiting block 29 and the placement block 19. Then, the hydraulic device external to the top of the pressing block 1 is turned on. The hydraulic device drives the pressing block 1 to descend, causing the pressing block 1 to slide down along the guide post 30, along with the mounting block 2, the punch 3, and the guide sleeve 31. The guide sleeve 31 and the guide post 30 guide the pressing block 1. Then, the punch 3 passes through the groove on the limiting block 29 and punches the sheet material, pushing the waste material down. The waste material falls from the leakage hole 20 on the placement block 19 into the collection cart 21 below. Then, the external hydraulic device drives the pressing block 1, the mounting block 2, and the punch 3 to rise and slide back up along the guide post 30 and the guide sleeve 31. Then, the sheet material is pushed forward to continue punching. When the collection cart 21 is full, the cylinder 25 is turned on, causing the cylinder 25 to drive the piston rod 26 in the forward direction. Then, the piston rod 26 pushes the lower locking block 27. The upper locking block 28 moves, causing the collection cart 21 to move. The collection cart 21 moves out of the base 18 along the moving cabinet groove via the moving wheels 23 installed at the bottom. Then, one side of the collection cart 21 is slightly lifted, causing the upper locking block 28 to disengage from the lower locking block 27. Then, the collection cart 21 is pulled by the handle 24, causing it to move via the moving wheels 23. The waste material in the collection cart 21 is then emptied and uniformly processed. After emptying, the upper locking block 28 on one side of the collection cart 21 is re-locked onto the lower locking block 27. Then, the cylinder 25 drives the piston rod 26 in the opposite direction, causing the piston rod 26 to move the collection cart 21 inward through the cooperation of the lower locking block 27 and the upper locking block 28. The moving cart moves along the moving wheel 23 installed at the bottom and slides into the base 18 along the moving groove 22. When the collection cart 21 is aligned with the leakage hole 20, the cylinder 25 is closed.

[0037] Please see Figure 4 and Figure 5 As a further implementation of the overall equipment: the snap-fit ​​groove 13 is a ring structure opened between the snap-fit ​​rod 12 and the push block 9.

[0038] Both the outer side of the snap-fit ​​block 8 and one side of the inner wall of the snap-fit ​​groove 13 are circular arc structures with equal radius centered on the pivot 10.

[0039] One end of the top spring 17 is connected to the limiting sleeve 5, and the other end of the top spring 17 is connected to the top plate 16 in a contact manner.

[0040] More specifically, when the punch 3 needs to be disassembled, maintained, or replaced, first rotate the top plate 16, causing the relief hole 15 to rotate. When the relief hole 15 rotates to a position concentric with the push rod 14, push the limiting sleeve 5, causing the limiting sleeve 5 to slide the push rod 14 into the relief hole 15. At the same time, the limiting sleeve 5 and the top plate 16 will cooperate to compress the top spring 17 sleeved on the outside of the push rod 14, and the inner wall of the limiting sleeve 5 will gradually press the limiting block 6 into the inner side of the adapter groove 11. Then the adapter block will drive the connecting plate 7 to rotate along the rotating shaft 10, and then the connecting plate 7 will drive the snap-fit ​​block 8 connected at the other end to rotate out of the snap-fit ​​groove 13. When the top spring 17 is compressed to the extreme... Within a limited time, the snap-fit ​​block 8 completely disengages from the snap-fit ​​groove 13. During this process, the inner side of the limiting block 6 pushes the push block 9 to one side, causing the push block 9 to move the snap-fit ​​groove 13 and the snap-fit ​​rod 12 downwards. Then, the snap-fit ​​sleeve 4 is pulled downwards to remove it from the outside of the snap-fit ​​rod 12. The other snap-fit ​​sleeves 4 are then removed following the same steps. Next, the mounting block 2 with the punch 3 installed is removed from under the pressure block 1. After the punch 3 has been maintained and replaced, the mounting block 2 is reinstalled under the pressure block 1, allowing the snap-fit ​​rod 12 to pass through the pre-drilled mounting hole on the mounting block 2. Then, the limiting sleeve 5 is slightly pushed in the opposite direction to move it to the rotating shaft 1. The position between the limiting sleeve 5 and the limiting block 6 is such that the limiting sleeve 5 only limits the outer wall of the connecting plate 7 where the limiting block 6 is connected. Then, the snap-fit ​​sleeve 4 is re-fitted onto the outside of the snap-fit ​​rod 12. Then, the push block 9 will gradually slide into the inside of the snap-fit ​​sleeve 4. Then, the end of the push block 9 will push the inner wall of the limiting block 6 outward, so that the limiting block 6 moves back to the outside of the adapter groove 11. At the same time, the limiting block 6 will drive the connecting plate 7 to rotate in the opposite direction along the rotating shaft 10 in the adapter groove 11. Then, the other part of the connecting plate 7 will drive the snap-fit ​​block 8 to rotate and reset, so that the snap-fit ​​block 8 is re-engaged in the snap-fit ​​groove 13, so that the snap-fit ​​sleeve 4 and the snap-fit ​​rod 12 re-establish the snap-fit ​​relationship. Then, the limiting sleeve 5 is completely released. The limiting sleeve 5 is made so that the top spring 17 pushes the limiting sleeve 5 to slide and reset. Then the limiting sleeve 5 will drive the top rod 14 to slide and reset. When the top spring 17 is fully reset, the top rod 14 disengages from the relief hole 15. Then the top plate 16 continues to rotate, so that the top plate 16 drives the relief hole 15 to rotate to a position that does not correspond to the top rod 14. This allows the top rod 14 to support the limiting sleeve 5. With the preload applied by the top spring 17, the limiting sleeve 5 will not slide easily. Then the limiting sleeve 5 limits the outer wall of the section of the connecting plate 7 with the snap-fit ​​block 8, preventing the snap-fit ​​block 8 from disengaging from the snap-fit ​​groove 13, thereby ensuring the stability of the installation structure and ensuring the stable use of the equipment.

[0041] In summary, when using or operating the equipment: First, place the material sheet between the limiting block 29 and the placement block 19. Then, activate the external hydraulic device at the top of the pressure block 1. The hydraulic device drives the pressure block 1 to descend, causing it to slide downwards along the guide post 30, along with the mounting block 2, punch 3, and guide sleeve 31. The guide sleeve 31 and guide post 30 guide the pressure block 1. The punch 3 then passes through the slot on the limiting block 29 and punches the material sheet, dislodging the waste material. The waste material falls through the leakage hole 20 on the placement block 19 into the collection cart 21 below. The external hydraulic device then drives the pressure block 1, mounting block 2, and punch 3 to rise and slide back up along the guide post 30 and guide sleeve 31, resetting them. The material sheet is then pushed forward to continue punching. When the collection cart 21 is full, the cylinder 25 is activated, causing it to drive the piston rod 26 in the forward direction. The piston rod 26 then pushes... The lower locking block 27 and the upper locking block 28 move, causing the upper locking block 28 to drive the collection cart 21 to move. The collection cart 21 moves out from the inside of the base 18 along the moving cabinet groove via the moving wheels 23 installed at the bottom. Then, one side of the collection cart 21 is slightly lifted, causing the upper locking block 28 to disengage from the lower locking block 27. Then, the collection cart 21 is pulled by the handle 24, causing the collection cart 21 to move via the moving wheels 23. Then, the waste material filled in the collection cart 21 is emptied and uniformly processed. After emptying, the upper locking block 28 on one side of the collection cart 21 is re-locked onto the lower locking block 27. Then, the cylinder 25 drives the piston rod 26 in the opposite direction, causing the piston rod 26 to drive the collection cart 21 to move inward through the cooperation of the lower locking block 27 and the upper locking block 28. The moving cart drives the moving wheels 23 installed at the bottom to slide into the interior of the base 18 along the moving groove 22. When the collection cart 21 is aligned with the leakage hole 20, the cylinder 25 is closed.

[0042] When the punch 3 needs to be disassembled, maintained, or replaced, first rotate the top plate 16, causing the relief hole 15 to rotate. When the relief hole 15 rotates to a position concentric with the push rod 14, push the limiting sleeve 5, causing the limiting sleeve 5 to slide the push rod 14 into the relief hole 15. At the same time, the limiting sleeve 5 and the top plate 16 will cooperate to compress the top spring 17 sleeved on the outside of the push rod 14, and the inner wall of the limiting sleeve 5 will gradually press the limiting block 6 into the inner side of the adapter groove 11. Then the adapter block will drive the connecting plate 7 to rotate along the rotating shaft 10. Then the connecting plate 7 will drive the snap-fit ​​block 8 connected at the other end to rotate out of the snap-fit ​​groove 13. When the top spring 17 is compressed to the limit, the snap-fit ​​block 17 will rotate out of the snap-fit ​​groove 13. The retaining block 8 completely disengages from the retaining groove 13. During this process, the inner side of the limiting block 6 pushes the pushing block 9 to one side, causing the pushing block 9 to move the retaining groove 13 and the retaining rod 12 downwards. Then, the retaining sleeve 4 is pulled downwards to remove it from the outside of the retaining rod 12. The other retaining sleeves 4 are then removed following the same steps. The mounting block 2 with the punch 3 installed is then removed from under the pressure block 1. After the punch 3 has been maintained and replaced, the mounting block 2 is reinstalled under the pressure block 1, and the retaining rod 12 passes through the pre-drilled mounting hole on the mounting block 2. Then, the limiting sleeve 5 is slightly pushed in the opposite direction, causing the limiting sleeve 5 to move to the pivot 10 and the limiting... The position of the blocks 6 is such that the limiting sleeve 5 only limits the outer wall of the connecting plate 7 where the limiting block 6 is connected. Then, the snap-fit ​​sleeve 4 is re-fitted onto the outside of the snap-fit ​​rod 12. Then, the push block 9 will gradually slide into the inside of the snap-fit ​​sleeve 4. Then, the end of the push block 9 will push the inner wall of the limiting block 6 outward, so that the limiting block 6 moves back to the outside of the adapter groove 11. At the same time, the limiting block 6 will drive the connecting plate 7 to rotate in the opposite direction along the rotating shaft 10 in the adapter groove 11. Then, the other part of the connecting plate 7 will drive the snap-fit ​​block 8 to rotate and reset, so that the snap-fit ​​block 8 is re-engaged in the snap-fit ​​groove 13, so that the snap-fit ​​sleeve 4 and the snap-fit ​​rod 12 re-establish the snap-fit ​​relationship. Then, the limiting sleeve is completely released. 5. The top spring 17 pushes the limiting sleeve 5 to slide and reset. Then the limiting sleeve 5 will drive the top rod 14 to slide and reset. After the top spring 17 is fully reset, the top rod 14 disengages from the relief hole 15. Then the top plate 16 continues to rotate, so that the top plate 16 drives the relief hole 15 to rotate to a position that does not correspond to the top rod 14. This allows the top rod 14 to support the limiting sleeve 5. With the preload applied by the top spring 17, the limiting sleeve 5 will not slide easily. Then the limiting sleeve 5 limits the outer wall of the section of the connecting plate 7 with the snap-fit ​​block 8, preventing the snap-fit ​​block 8 from disengaging from the snap-fit ​​groove 13, thereby ensuring the stability of the installation structure and ensuring the stable use of the equipment.
