Description
Technical Field
[0001] This utility model relates to the field of battery steel shell stretching mold technology, and in particular to a cylindrical battery steel shell stretching mold. Background Technology
[0002] The cylindrical battery steel shell stretching die is the core tooling for the production of cylindrical battery steel shells. It is used to process thin steel plates into cylindrical steel shells with specific inner diameters, wall thicknesses, and heights through multiple continuous stretching processes. Its function is to precisely control the dimensional accuracy and surface quality of the steel shell, avoid defects such as wrinkling and cracking, adapt to the needs of automated mass production, and directly determine whether the battery steel shell can meet the subsequent packaging and battery safety and performance requirements.
[0003] In practical applications, existing cylindrical battery steel shell stretching dies, using a combination of punches and blank holders, can meet the basic requirements for thin steel sheet stretching. However, the following problems still exist: Common cylindrical battery steel shell stretching dies often employ a single fixing method when stretching the steel shell. When the punch needs to be inspected or repaired, it requires the cooperation of manual labor and machinery. This process demands high coordination between manual labor and machinery, and the installation process is quite cumbersome. Furthermore, during disassembly, since the punch is only held in position by partially removed bolts and temporary manual support, it may accidentally fall off due to its own weight or operational errors, affecting the safety of the workers. Therefore, this application provides a cylindrical battery steel shell stretching die to meet these requirements. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cylindrical battery steel shell stretching mold.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cylindrical battery steel shell stretching die, comprising a support base and a die disposed on the top of the support base, the top of the die being provided with a punch, and further comprising: An auxiliary component includes a support rod connected to the top of the punch.

Detailed Implementation
[0015] 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.
[0016] like Figure 1 - Figure 5 As shown, this embodiment provides a technical solution: a cylindrical battery steel shell stretching die, including a support base 1 and a die 11 disposed on the top of the support base 1, the top of the die 11 being provided with a punch 12, and further including: Auxiliary component 2 includes a support rod 25 connected to the top of the punch 12. The outer surface of the support rod 25 is provided with a first fixing plate 26 and a sliding plate 27. The side of the support rod 25 is provided with a snap-fit block 24, and the side of the snap-fit block 24 is provided with a telescopic rod 210. Support assembly 3 includes a protective shell 31 connected to the bottom of the inner cavity of the support base 1, a first spring piece 22 provided on the side of the telescopic rod 210, a connecting plate 23 connected to the side of the locking block 24 away from the support rod 25, the side of the connecting plate 23 being fixedly connected to one end of the telescopic rod 210, a limit plate 21 provided on the top of the connecting plate 23, a groove 29 being provided on the outer surface of the support rod 25, and a second spring piece 28 connected to the inner cavity of the groove 29. Through the cooperation of the die 11 and the punch 12, the steel shell can be subjected to a pulling process. When installing the punch 12, the punch 12 is first manually moved towards the protective shell 31. When the punch 12 moves to a certain position, the top of the first fixed plate 26 contacts the inclined surface of the bottom of the snap-fit block 24, thereby causing the snap-fit block 24 to move the connecting plate 23 away from the support rod 25. During the movement of the connecting plate 23, the first spring 22 is compressed. At this time, the first fixed plate 26 continues to move upward. When the bottom of the first fixed plate 26 moves to the top of the snap-fit block 24, the first spring 22 releases stress, thereby causing the connecting plate 23 to reset the snap-fit block 24. During the movement of the connecting plate 23, the limiting plate 21 and the telescopic rod 210 cooperate to fix the connecting plate 23. The movement trajectory of the connecting plate 23 is limited to prevent positional deviation. After the snap-fit is completed, the worker can directly use the lead screw and mounting plate on the side of the punch 12 to fix the punch 12 a second time. This eliminates the need for multiple people or equipment to hold the punch 12 for a long time during installation, effectively improving work efficiency. When it is necessary to disassemble the punch 12, the worker can directly loosen the lead screw. When releasing the threaded connection, the first fixing plate 26, the snap-fit block 24, and the sliding plate 27 ensure that the punch 12 will not fall off directly. At this time, the worker can push the punch 12 upward again, thereby causing the support rod 25 to drive the second... A fixed plate 26 and a sliding plate 27 enter the inner cavity of the groove 32. When the top of the sliding plate 27 contacts the inclined surface at the bottom of the snap-fit block 24, the snap-fit block 24 retracts again. At this time, the punch 12 is pulled down, which causes the top plane of the snap-fit block 24 to contact the bottom of the sliding plate 27. This causes the sliding plate 27 to compress the second spring 28. When the top of the sliding plate 27 is in contact with the bottom of the first fixed plate 26, the reverse stress on the snap-fit block 24 increases, which causes the snap-fit block 24 to retract. This achieves the effect of removing the punch 12, ensuring the safety of the workers during the disassembly process.
[0017] Furthermore, such as Figure 3 As shown: The top of the protective shell 31 is provided with a groove 32, and the inner cavity of the protective shell 31 is connected to a second fixing plate 33. By providing the groove 32, the support rod 25 can be provided with a space for movement. By providing the second fixing plate 33, the telescopic rod 210 and the first spring piece 22 can be supported. By providing the protective shell 31, the auxiliary component 2 can be protected.
[0018] Working principle: like Figure 1-5 As shown: In use: First, manually push the punch 12 towards the end closer to the protective shell 31. When the punch 12 moves to a certain position, the top of the first fixing plate 26 contacts the inclined surface at the bottom of the snap-fit block 24, thereby causing the snap-fit block 24 to drive the connecting plate 23 to move away from the support rod 25. During the movement of the connecting plate 23, the first spring 22 is compressed. At this time, the first fixing plate 26 continues to move upward to the top of the snap-fit block 24. At this time, the first spring 22 releases stress, thereby causing the connecting plate 23 to drive the snap-fit block 24 to reset, thus achieving the effect of auxiliary fixing of the punch 12. After snap-fitting, the operator uses the [unclear - possibly a device or tool] located on the side of the punch 12 to [unclear - possibly a device or tool]. The lead screw and mounting plate provide secondary fixation for the punch 12. Activating the die 11 and punch 12 allows for the pulling and forming of the steel shell. Similarly, when the punch 12 needs to be disassembled, the operator can directly loosen the lead screw. When disengaging the threaded connection, the first fixing plate 26, the locking block 24, and the sliding plate 27 work together to ensure that the punch 12 does not fall off directly. At this point, the operator pushes the punch 12 upwards again, causing the locking block 24 to retract. When it retracts to a certain position, the punch 12 is pulled downwards, causing the support rod 25 to disengage the first fixing plate 26 and the sliding plate 27 from the locking block 24, thus allowing the punch 12 to be completely disassembled.
[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
