[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 The present invention provides an embodiment of a large rotary stamping die for preventing punch jamming, comprising an upper die 1, a lower die 10 and a punch 24. Guide blocks 2 are provided at both ends of the upper end of the front end of the upper die 1. A micro switch 5 is provided on the right side of the top of the front end of the upper die 1. A bent rod 4 is provided on one side of the micro switch 5. The upper die 1 and the lower die 10 cooperate with each other. The interior of the upper die 1 is provided with a protective structure to prevent the punch 24 from jamming.
[0026] The protective structure includes a push plate 17, a limiting groove 21, and a spring 23. The upper mold 1 has a cavity 16 inside. A punch 24 is movably connected to the front end of the upper mold 1. A connecting plate 22 is fixedly connected to the rear end of the punch 24. A spring 23 is fixedly connected between the connecting plate 22 and the upper mold 1. The push plate 17 is provided inside the cavity 16. A limiting groove 21 is provided inside the push plate 17. A connecting block 20 is fixedly connected to the rear end of the push plate 17. A hydraulic cylinder 18 is installed on the left side inside the cavity 16.
[0027] The upper mold 1 has a first groove 3 on the left and right sides of the upper and lower ends. The front end of the upper mold 1 is machined with a reserved groove 7. The lower mold 10 has a second groove 14 on the left and right sides of the upper and lower ends. The upper mold 1 and the lower mold 10 have an installation groove 11 on the left side. The front end of the lower mold 10 has a placement groove 13. The rear end of the lower mold 10 is equipped with a rotating shaft 15. The top of the front end of the upper mold 1 is equipped with a cylinder 6. The left side of the front end of the lower mold 10 is equipped with an installation plate 12. The connecting plate 22 is embedded in the limiting groove 21. The hydraulic cylinder 18 is installed on the left side of the connecting block 20. The punch 24 slides inside the upper mold 1. The spring 23 is located at the rear end of the punch 24.
[0028] Specifically, such as Figure 3 and Figure 4 As shown, when the hydraulic cylinder 18 is activated, the hydraulic cylinder 18 drives the push plate 17 to move through the connecting block 20. The movement of the push plate 17 can disengage the connecting plate 22 from the inside of the limiting groove 21, thereby squeezing the punch 24 and causing the punch 24 to descend. After use, the hydraulic cylinder 18 is activated again, and the hydraulic cylinder 18 drives the push plate 17 back to its original position. The spring 23 can then use its own elasticity to raise the connecting plate 22 into the inside of the limiting groove 21, thereby preventing impurities from clogging between the upper mold 1 and the punch 24 and causing the punch 24 to jam.
[0029] The rear end of the cavity 16 is machined with a limiting groove 19, and the front end of the connecting block 20 is fixedly connected to a limiting slider 25. The limiting slider 25 has a rolling groove 27 inside, and a ball 26 is provided inside the rolling groove 27. The limiting slider 25 slides left and right inside the limiting groove 19, and the ball 26 rolls inside the rolling groove 27.
[0030] Specifically, such as Figure 3 and Figure 4 As shown, when the push plate 17 moves, the limiting slider 25 at the top of the connecting block 20 will slide left and right inside the limiting groove 19, which can improve the stability of the connecting block 20 and the push plate 17. When the limiting slider 25 moves, the ball 26 will roll inside the rolling groove 27, which can reduce the friction between the limiting slider 25 and the limiting groove 19 and facilitate the sliding of the limiting slider 25.
[0031] The front end of the upper mold 1 is fixedly connected to a hinge block 9. The hinge block 9 is movably hinged to a limit block 8. The hinge block 9 is located on one side of the bent rod 4. The limit block 8 rotates outside the hinge block 9 and is located at the front end of the bent rod 4.
[0032] Specifically, such as Figure 1 As shown, when the bent rod 4 needs to be fixed, the limiting block 8 needs to be rotated. Since the limiting block 8 is movably hinged to the outside of the hinge block 9, and the hinge block 9 is located on one side of the bent rod 4, rotating the limiting block 8 can rotate the front end of the bent rod 4, thereby limiting and fixing the bent rod 4 and preventing the bent rod 4 from accidentally falling off the upper mold 1.
[0033] Working principle: When in use, the hydraulic cylinder 18 is activated, which drives the push plate 17 to move via the connecting block 20. The movement of the push plate 17 disengages the connecting plate 22 from the limiting groove 21, thereby pressing the punch 24 and causing it to descend. After use, the hydraulic cylinder 18 is activated again, returning the push plate 17 to its original position. The spring 23, through its elasticity, allows the connecting plate 22 to rise back into the limiting groove 21, preventing impurities from clogging between the upper mold 1 and the punch 24 and causing the punch 24 to jam. When the push plate 17 moves, the limiting slider 2 at the top of the connecting block 20... 5 will slide left and right inside the limiting slide groove 19, thereby improving the stability of the connecting block 20 and the push plate 17. When the limiting slider 25 moves, the ball 26 will roll inside the rolling groove 27, which can reduce the friction between the limiting slider 25 and the limiting slide groove 19 and facilitate the sliding of the limiting slider 25. When it is necessary to fix the bent rod 4, rotate the limiting block 8. Since the limiting block 8 is movably hinged to the outside of the hinge block 9, and the hinge block 9 is set on one side of the bent rod 4, rotating the limiting block 8 can rotate the front end of the bent rod 4, thereby limiting and fixing the bent rod 4 and preventing the bent rod 4 from accidentally falling off the upper mold 1.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
