[0001] This utility model relates to the field of aluminum shell processing technology for explosion-proof valves, and in particular to a stamping mechanism for aluminum shells of explosion-proof valves. Background Technology
[0002] Explosion-proof valve aluminum shell refers to the outer shell part used in explosion-proof valves. It is usually made of aluminum alloy material. Stamping process has become the preferred choice for explosion-proof valve aluminum shell due to its characteristics of efficient forming, lightweight, low-cost mass production and high precision. Especially in the battery field, stamped aluminum shell achieves the best balance between safe pressure relief and structural durability. During the processing of explosion-proof valve aluminum shell, it is necessary to form indentation grooves on the bottom or side wall of the aluminum shell through stamping, so that the shell wall thickness in this part is lower than that in other areas.
[0003] Currently, after the aluminum shell of the explosion-proof valve is stamped, manual demolding is required by workers during the demolding process, which is time-consuming, labor-intensive, and inconvenient. In order to better solve the problem of labor-intensive manual demolding, and also to promote the development of the industry's technical level and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.
[0023] Referring to Figures 1-4, an explosion-proof valve aluminum shell stamping mechanism includes a worktable 9. A stamping assembly is provided on the upper surface of the worktable 9. The stamping assembly includes a vertical rod welded to the upper surface of the worktable 9. A vertical groove 5 is formed on one side of the vertical rod. A connecting block 3 is slidably connected within the vertical groove 5. A bearing plate is welded to one side of the connecting block 3. A hydraulic cylinder 10 is bolted to the upper surface of the bearing plate. One end of the pneumatic rod of the hydraulic cylinder 10 passes through the bearing plate and is bolted to a punch 13. A power assembly is provided within the vertical groove 5 to drive the connecting block 3 to move up and down along the vertical groove 5. The power assembly includes a threaded rod 2, which is rotatably connected to the vertical groove 5 via a bearing. The threaded rod 2 passes through the connecting block 3. Connecting block 3 is threadedly connected to connecting block 3. The top of the vertical rod is fixed with a self-locking motor 1 that drives the threaded rod 2 to rotate. When stamping is required, the self-locking motor 1 is started, which drives the threaded rod 2 to rotate. The threaded rod 2 engages with the thread of connecting block 3, causing connecting block 3 to move downward along vertical groove 5. Connecting block 3 drives the bearing plate to move downward, thereby causing punch 13 to move downward. When punch 13 moves downward to a suitable height, the height of the bearing plate is fixed by the self-locking function of self-locking motor 1. Then, hydraulic cylinder 10 is started to extend, and hydraulic cylinder 10 pushes punch 13 downward, so that punch 13 stamps the stamped part.
[0024] In this invention, a groove is provided on the upper surface of the worktable 9, and a rotating shaft 17 is rotatably connected in the groove. A working plane 7 is welded to the top of the rotating shaft 17. A drive assembly for manually rotating the working plane 7 is provided on one side of the worktable 9. The drive assembly includes a connecting shaft 15. A rotating hole communicating with the groove is provided on one side of the worktable 9. The connecting shaft 15 is rotatably connected in the rotating hole. A bevel gear 16 is keyed to the outer side of the rotating shaft 17 and one end of the connecting shaft 15. The two bevel gears 16 mesh with each other and move the connecting shaft 15. The meshing of the two bevel gears 16 causes the rotating shaft 17 to rotate. The rotating shaft 17 drives the working plane 7 to rotate. The working plane 7 drives the die 8 to rotate, thereby changing the position of the die 8. The remaining dies 8 are rotated to be directly below the punch 13 for stamping, thereby realizing multi-station stamping and improving the use effect of the stamping mechanism.
[0025] In particular, the upper surface of the working plane 7 is fixed with multiple uniformly symmetrically distributed dies 8 by bolts, the bottom of the worktable 9 is fixed with a vertical plate 4 by bolts, a slide groove 20 is provided on one side of the vertical plate 4, a guide rod 6 is slidably connected in the slide groove 20, a rack 22 is fixed to one end of the guide rod 6 by bolts, a push rod 24 is welded to the top of the rack 22, the bottom of the multiple dies 8 is provided with an insertion port, the upper surface of the working plane 7 is provided with a through port connected to the insertion port at the position below the dies 8, the push rod 24 passes through the worktable 9 and can be inserted into the through port and the insertion port, and the bottom of the worktable 9 is provided with a power mechanism to drive the rack 22 to move upward;
[0026] The power mechanism includes two fixed blocks 19, both welded to the bottom of the worktable 9. A rotating rod 21 is rotatably connected between the two fixed blocks 19 via bearings. A gear 23 that meshes with a rack 22 is keyed to the outside of the rotating rod 21. A self-locking motor 11 that drives the rotating rod 21 is fixed to one side of one of the fixed blocks 19 by bolts. When the stamping is completed and needs to be removed, the stamped die 8 is rotated to the top of the ejector pin 24, and then the self-locking motor 11 is started. The self-locking motor 11 drives the rotating rod 21 to rotate, which in turn drives the gear 23 to rotate. The gear 23 meshes with the rack 22, causing the rack 22 to move upward along the slide groove 20 via the guide rod 6. The rack 22 pushes the ejector pin 24 upward, causing the ejector pin 24 to pass through the through-hole and the insertion hole to eject the stamped part from the die 8. This makes it easier for the workers to remove the stamped aluminum shell, saving time and improving work efficiency.
[0027] It should be noted that a fixed seat 18 is welded to the upper surface of the working plane 7. A threaded hole is provided on one side of the fixed seat 18, and a lead screw 26 is threaded into the threaded hole. A conical block 14 is welded to one end of the lead screw 26. Multiple conical grooves 25 are provided on the outer circumference of the working plane 7, and the conical block 14 is inserted into the conical groove 25. The multiple conical grooves 25 are respectively located on the same straight line as multiple dies 8. When the working plane 7 is rotated until the conical block 14 is facing the conical groove 25, the rotation of the working plane 7 is stopped, and the lead screw 26 is rotated. The lead screw 26 will push the conical block 14 into the conical groove 25. At this time, the conical surface of the conical block 14 and the conical groove 25 will automatically correct the working plane 7, thereby ensuring that one of the dies 8 and the punch 13 are aligned vertically, and at the same time ensuring that the ejector pin 24 is aligned with the through and the insertion port.
[0028] Working principle: When stamping is required, the stamping part is placed on the die 8, and then the connecting shaft 15 is rotated. The connecting shaft 15, through the meshing of two bevel gears 16, causes the rotating shaft 17 to rotate. The rotating shaft 17 drives the working plane 7 to rotate, and the working plane 7 drives the die 8 to rotate. When the working plane 7 rotates until the conical block 14 is aligned with the conical groove 25, the rotation of the working plane 7 is stopped, and the lead screw 26 is rotated. The lead screw 26 pushes the conical block 14 into the conical groove 25. At this time, the conical block 14... The conical surface of the conical groove 25 automatically corrects the working plane 7, thereby aligning one of the concave dies 8 vertically with the convex die 13. Then, the self-locking motor 1 is activated, which drives the threaded rod 2 to rotate. The threaded rod 2 engages with the threaded connection block 3, causing the connection block 3 to move downward along the vertical groove 5. The connection block 3 then drives the support plate downward, thereby moving the convex die 13 downward. When the convex die 13 moves downward to a suitable height, the self-locking function of the self-locking motor 1 adjusts the height of the support plate. The angle is fixed, then the hydraulic cylinder 10 is extended, which pushes the punch 13 downward, causing the punch 13 to stamp the part. After stamping, the hydraulic cylinder 10 retracts, and then the conical block 14 disengages from the conical groove 25 and continues to rotate the working plane 7, causing the next die 8 to rotate directly below the punch 13, thus stamping the next part. When the stamping is complete and needs to be removed, the stamped die 8 is rotated directly above the ejector pin 24, and then removed through the conical block 14 and the conical groove 25. The tapered groove 25 is used for positioning, and then the self-locking motor 21 is started. The self-locking motor 21 drives the rotating rod 21 to rotate, which in turn drives the gear 1 23 to rotate. The gear 1 23 meshes with the rack 22, causing the rack 22 to move upward along the slide groove 20 through the guide rod 6. The rack 22 pushes the ejector rod 24 upward, causing the ejector rod 24 to pass through the through-hole and the insertion hole to eject the stamped part in the die 8. This makes it easier for the workers to remove the stamped aluminum shell, saving time and improving work efficiency.
[0029] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
