Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a continuous stamping die for a battery cover. Background Technology

[0002] Stamping dies (also known as cold stamping dies or hardware dies) are special process equipment used at room temperature to apply pressure to materials (metal or non-metal) using dies mounted on a press, causing them to separate or plastically deform, thereby obtaining the desired parts. Battery covers are an important component of batteries, and their main function is to protect the internal structure of the battery. Since battery covers need to fit the end face of the battery casing, compared with cutting or casting, direct stamping can produce battery cover products more quickly.

[0003] The published patent document CN219004251U discloses a continuous stamping die assembly. In this patent, when the die moves downwards for stamping, the die drives a push rod downwards, which abuts against one end of a lever. The other end of the lever tilts upwards, pushing a top block upwards. When the die cuts a long plate, the top block blocks the through hole, thus supporting the bottom of the long plate and preventing it from denting during stamping. This improves the quality of products produced by the continuous stamping die assembly. However, the aforementioned patent document cannot simultaneously perform loading, stamping, and unloading operations for different products, lacks continuous stamping functionality, and has low work efficiency.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-2 This utility model provides a continuous stamping die for a battery cover, including a main body 1. The main body 1 has a first groove 2 and a second groove 3. A disc 4 is provided on the lower side of the interior of the main body 1, and an upper die 16 is provided on the upper side of the interior of the main body 1. Several die seats 6 are fixedly installed at equal intervals on the outer edge of the top of the disc 4. A lower die 7 is fixedly connected to the top of the die seats 6. A rotating shaft 5 is rotatably installed inside the second groove 3, and a servo motor 14 is fixedly installed on the inner wall of the top of the second groove 3. The upper end of the rotating shaft 5 is fixedly installed at the middle of the bottom of the disc 4, and a large gear 13 is sleeved and fixedly installed on the rotating shaft 5. A small gear 15 is fixedly installed at the output end of the servo motor 14, and the small gear 15 is meshed with the large gear 13.

[0022] In this technical solution, the servo motor 14 drives the pinion 15 to rotate, and the pinion 15 and the large gear 13 drive the rotating shaft 5 to rotate at a reduced speed, thereby rotating each lower mold 7 on the disc 4 to the lower part of the upper mold 16 in sequence. This allows for the simultaneous loading, stamping and unloading of different battery covers, achieving continuous stamping and increasing work efficiency.

[0023] In some technical solutions, such as Figure 1 , Figure 3 and Figure 4As shown, a matching kit 17 is fitted and slidably connected to the lower mold 7. Four vertical shafts 18 are slidably connected through the kit 17. The lower end of the vertical shaft 18 is fixedly installed to the top of the mold base 6. A spring 19 is fitted on the vertical shaft 18. The upper and lower ends of the spring 19 are respectively connected to the bottom of the kit 17 and the top of the mold base 6. A connecting ear 20 is fixedly installed on one side of the main body 1. A support shaft 21 is fixedly installed on the top of the connecting ear 20. A stripper plate 8 matching the lower mold 7 is fixedly installed on the upper end of the support shaft 21. The stripper plate 8 is located inside the groove 2.

[0024] When in use, when the upper mold 16 moves down to the lower mold 7 for stamping, it will drive the kit 17 to slide down along the lower mold 7. At this time, the kit 17 squeezes the spring 19. When the stamping is finished and the upper mold 16 is reset, the kit 17 is reset by the elastic force of the spring 19, which lifts up the stamped battery cover. During the rotation of the disc 4, the battery cover contacts the unloading plate 8 to complete the automatic unloading. There is no need for manual unloading, which is convenient to operate.

[0025] In some technical solutions, such as Figure 1-2 As shown, a hydraulic cylinder 9 is fixedly installed on the top of the main body 1, and the output end of the hydraulic cylinder 9 is fixedly installed on the top of the upper mold 16.

[0026] In use, the upper mold 16 is moved vertically by the hydraulic cylinder 9, providing a power source for the stamping operation.

[0027] In some technical solutions, such as Figure 1 and Figure 4 As shown, a collection box 10 is fixedly installed on one side of the main body 1, and the collection box 10 is located diagonally below the unloading plate 8.

[0028] When in use, the battery cover that is automatically unloaded can be collected through the collection box 10.

[0029] In some technical solutions, such as Figure 1-2 As shown, several balls 11 are equidistantly mounted on the outer edge of the bottom of the disc 4, and the bottom of the balls 11 contacts the inner wall of the bottom of the groove 2.

[0030] During use, the ball bearings 11 ensure the overall stability of the disc 4.

[0031] In some technical solutions, such as Figure 1-2 As shown, several legs 12 are fixedly connected to the outer edge of the bottom of the main body 1, and anti-slip pads are fixedly installed at the lower end of the legs 12.

[0032] When in use, the anti-slip pads at the lower end of the support legs 12 increase the stability of the main body 1.

[0033] Working principle: During use, the metal sheet to be stamped is placed on the lower die 7. The servo motor 14 drives the pinion 15 to rotate. The pinion 15 and the large gear 13 drive the rotating shaft 5 to decelerate and rotate, thereby rotating each lower die 7 on the disc 4 to the lower die 16 in sequence. The hydraulic cylinder 9 drives the upper die 16 to move downward to the lower die 7 for stamping operation, and drives the component 17 to squeeze the spring 19 to slide downward along the lower die 7. When the stamping is finished and the upper die 16 is reset, the elastic force of the spring 19 drives the component 17 to reset, lifting the stamped battery cover. As the disc 4 continues to rotate, the battery cover contacts the unloading plate 8 and falls into the collection box 10, completing the automatic unloading.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
