Detailed implementation manners

[0023] The following will further describe the present application in detail with reference to the Figure 1 - attached Figure 4 drawings.

[0024] The embodiment of the present application discloses a stamping die that is convenient for disassembly and assembly. Referring to Figure 1 - attached Figure 4 , a stamping die that is convenient for disassembly and assembly includes a base 1, a top plate 2, an upper stamping die 3 and a lower stamping die 4. The lower stamping die 4 is installed on the base 1 through bolts, and the upper stamping die 3 is fixed on the top plate 2;

[0025] A connecting block 22 is fixed to the top of the top plate 2. The top plate 2 is fixed with a connecting plate 7 through the connecting block 22. Two second avoidance grooves 14 are arranged in a staggered manner on the connecting plate 7;

[0026] It further includes a fixing box 5. Two first avoidance grooves 13 are provided in the bottom of the fixing box 5 above the two second avoidance grooves 14. The fixing box 5 is located above the connecting plate 7. The top of the fixing box 5 is installed with a top cover 6 through bolts and internally fixed with a fixing rod 8. A gear 9 is sleeved on the outer wall of the fixing rod 8. The inside of the top cover 6 is also slidably connected with symmetrically distributed first L-shaped tooth plates 10 and second L-shaped tooth plates 11. The first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 are both meshed with the gear 9. A clamping plate 12 is fixed below each of the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11, and both clamping plates 12 penetrate through the first avoidance grooves 13 and the second avoidance grooves 14. Second positioning blocks 19 are fixed on both the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11, and a push rod 20 is fixed on each of the two second positioning blocks 19. Both push rods 20 penetrate through the fixing box 5. When in use, first, the fixing box 5 is installed on the output end of the power hydraulic cylinder by bolts;

[0027] When the lower stamping die 4 needs to be installed, the lower stamping die 4 is fixed on the base 1 by two bolts. Since the lower stamping die 4 does not need to move, its installation process is relatively simple and stable, and it is also convenient to disassemble;

[0028] When the upper stamping die 3 needs to be installed, the staff can push the push rod 20 to move into the fixing box 5, and drive the first L-shaped tooth plate 10 or the second L-shaped tooth plate 11 to move by using the push rod 20. Since both the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 are meshed with the gear 9, when they move, they will drive the gear 9 to rotate, and then make the other L-shaped tooth plate move in the reverse direction through the rotation of the gear, so that both clamping plates 12 can be located directly below the two first avoidance grooves 13. Subsequently, the two second avoidance grooves 14 on the connecting plate 7 are penetrated through the clamping plates 12, so that the clamping plates 12 can pass through the connecting plate 7 to complete the preliminary installation positioning;

[0029] Then, the staff pulls the push rod 20 to make the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 move in the reverse direction, driving the two clamping plates 12 to move to both sides simultaneously until one side of the clamping plate 12 is closely attached to the bottom of the connecting plate 7. At this time, the clamping plate 12 completely fixes the connecting plate 7, thus realizing the rapid installation and positioning between the upper stamping die 3 and the power hydraulic cylinder;

[0030] When it is necessary to disassemble the upper stamping die 3 and the lower stamping die 4, just operate the above steps in reverse. First, the staff pushes the push rod 20 again, so that the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 move in the reverse direction again, driving the two clamping plates 12 to move towards the middle until both clamping plates 12 are retracted into the first avoidance groove 13. At this time, the fixed state between the clamping plate 12 and the connecting plate 7 is released, and the staff can easily remove the connecting plate 7, thereby realizing the rapid disassembly between the upper stamping die 3 and the power hydraulic cylinder. Compared with the traditional bolt connection method, this design not only greatly simplifies the installation steps and improves work efficiency, but also makes the connection between the upper stamping die 3 and the power hydraulic cylinder more stable and reliable through the fixation of the clamping plate 12. This connection method only requires a simple pushing operation to achieve rapid installation and disassembly, greatly reducing the cumbersome steps brought by bolt connection and improving work efficiency.

[0031] Refer to Figure 3 , a sleeve 21 for sleeving on the fixed rod 8 is fixed at the bottom of the top cover 6; during use, it can prevent the gear 9 from moving up and down on the outer wall of the fixed rod 8. The height of the sleeve 21 is less than the height of the fixed rod 8, which can prevent the bottom end of the sleeve 21 from fitting on the top surface of the gear 9, thus affecting the normal rotation of the gear 9. At the same time, the design of the sleeve 21 can also enhance the connection stability between the top cover 6 and the fixed rod 8 to a certain extent, ensuring the stability of the entire structure.

[0032] Refer to Figure 2 , Figure 3 and Figure 4 , connecting frames 17 and first positioning blocks 16 are fixed on both sides of the gear 9 on the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11. Guide rods 15 are fixed on both connecting frames 17, and the guide rods 15 all penetrate through the first positioning blocks 16. A return spring 18 is also sleeved on the outer wall of the guide rod 15, and the return spring 18 is located between the first positioning block 16 and the connecting frame 17; during use, the return spring 18 provides a stable return force for the movement of the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11, ensuring that after the operation is completed, the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 can accurately return to the initial position to prepare for the next installation or disassembly operation. In addition, the combined structure of the guide rod 15 and the first positioning block 16 provides a stable installation environment for the return spring 18, avoiding the dislocation or distortion of the return spring 18, thereby ensuring its stable operation.

[0033] Refer to Figure 2 and Figure 3, the first positioning block 16, the connecting frame 17, and the second positioning block 19 are all fixed to the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 by bolts; this bolt-fixed design not only enhances the stability of the entire structure but also facilitates subsequent maintenance and replacement. When any component wears out due to long-term use, the staff only needs to simply remove the bolts to replace the worn part without having to disassemble the entire structure on a large scale, greatly saving maintenance costs and time.

[0034] Referring to Figure 2 and Figure 3 , the widths of both the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 are greater than the width of the first avoidance groove 13; this design ensures that the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 have sufficient contact area, thereby enhancing their stability during movement.

[0035] Referring to Figure 1 and Figure 2 , support rods 23 are fixed to the four corners at the bottom of the connecting plate 7; this design forms a stable support structure between the connecting plate 7 and the top plate 2.

[0036] The implementation principle of a stamping die that is easy to disassemble and assemble in an embodiment of this application is as follows: during use, first, the fixed box 5 is installed on the output end of the power hydraulic cylinder using bolts;

[0037] When installing the lower stamping die 4, the lower stamping die 4 is fixed to the base 1 by two bolts. Since the lower stamping die 4 does not need to move, its installation process is relatively simple and stable, and it is also convenient to disassemble;

[0038] When installing the upper stamping die 3, the staff can push the push rod 20 to move inside the fixed box 5, and use the push rod 20 to drive the first L-shaped tooth plate 10 or the second L-shaped tooth plate 11 to move. Since both the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 are engaged with the gear 9, when they move, they will drive the gear 9 to rotate, and then through the rotation of the gear, the other L-shaped tooth plate will move in the opposite direction, so that both the clamping plates 12 can be located directly below the two first avoidance grooves 13. Subsequently, the two second avoidance grooves 14 on the connecting plate 7 penetrate through the clamping plates 12, enabling the clamping plates 12 to pass through the connecting plate 7 to complete the preliminary installation positioning;

[0039] Then, the staff pulls the push rod 20, causing the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 to move in the opposite direction, driving the two clamping plates 12 to move towards both sides simultaneously until one side of the clamping plate 12 is closely attached to the bottom of the connecting plate 7. At this time, the clamping plate 12 completely fixes the connecting plate 7, thus achieving the rapid installation and positioning between the upper stamping die 3 and the power hydraulic cylinder;

[0040] When it is necessary to disassemble the upper stamping die 3 and the lower stamping die 4, just operate the above steps in reverse. First, the staff pushes the push rod 20 again, so that the first L-shaped tooth plate 10 and the second L-shaped tooth plate 11 move in the reverse direction again, driving the two clamping plates 12 to move towards the middle until both clamping plates 12 are retracted into the first avoidance groove 13. At this time, the fixed state between the clamping plate 12 and the connecting plate 7 is released, and the staff can easily remove the connecting plate 7, thereby realizing the rapid disassembly between the upper stamping die 3 and the power hydraulic cylinder. Compared with the traditional bolt connection method, this design not only greatly simplifies the installation steps and improves work efficiency, but also makes the connection between the upper stamping die 3 and the power hydraulic cylinder more stable and reliable through the fixation of the clamping plate 12. This connection method only requires a simple pushing operation to achieve rapid installation and disassembly, greatly reducing the cumbersome steps brought by bolt connection and improving work efficiency.
