Description

Technical Field

[0001] This utility model belongs to the field of battery steel shell processing technology, and in particular relates to a lithium battery cylindrical steel shell stamping device. Background Technology

[0002] The cylindrical steel shell of a lithium battery is a cylindrical battery casing made of nickel-plated steel sheet through multiple stamping processes. The cylindrical steel shell, which is formed in one piece through the stamping process, has high physical stability and pressure resistance, which can ensure the stability and safety of the battery. The stamping equipment is mainly used to complete the stamping and forming process of the steel shell during the production of the cylindrical steel shell.

[0003] As disclosed in Utility Model No. CN222094456U, a pre-nickel-plated cylindrical battery steel shell stamping device relates to the field of battery steel shell processing technology. This utility model includes a base plate; a workstation plate is positioned directly above the base plate; a hydraulic cylinder is fixed to the upper surface of a vertical plate above the workstation plate; a mold is positioned above the workstation plate at a location corresponding to the workstation opening; a support plate is mounted on the lower surface of the mold, sliding within the workstation opening; a punch rod aligned with the axis of a positioning ring is fixed to the lower surface of a mounting plate; a reduction motor is fixed to the upper surface of the base plate; and two symmetrically arranged adjustment ports are provided on the upper part of the periphery of each workstation opening. A spring is fixed to the bottom surface of the adjustment port, abutting against the lower surface of a lug. This utility model, through the combined use of the support plate and springs, facilitates the ejection of the mold, enabling mold loading and unloading. Simultaneously, the reduction motor drives the workstation openings on the workstation plate to rotate sequentially to a position directly below the hydraulic cylinder, achieving multi-station automatic stamping functionality. However, during the application of this technical solution, the stamping process is exposed to the equipment operating environment. If a tool breakage or die explosion occurs during the stamping process, it can easily cause injury to the workers operating the equipment. There is a technical problem that it is not possible to isolate the stamping station from the external working environment to ensure the safety of the workers while making it convenient for them to pick up and put away the steel shell.

[0023] Please see Figure 1-4 As shown, this utility model is a lithium battery cylindrical steel shell stamping device, including a frame 1, and further including: a work station plate 5 is provided at the front end of the bottom inner side of the frame 1, a mold 6 is provided at the top edge of the work station plate 5, an mounting head 13 is provided at the bottom end of the mold 6, a positioning groove 18 is provided at the top edge of the work station plate 5, an external thread is provided on the outer side of the mounting head 13, and an internal thread that mates with the external thread is provided on the inner side of the positioning groove 18. The mounting head 13 is installed and fixed inside the positioning groove 18 by a threaded connection, thereby stably positioning the mold 6 at the designated position on the work station plate 5. A hydraulic cylinder 9 is inserted at the middle position of the front end of the top of the frame 1, and a punch 10 is provided at the bottom end of the hydraulic cylinder 9. After the pre-made cylindrical steel shell is placed in the mold 6, the hydraulic cylinder 9 is activated to descend and drive the punch 10 to stamp the shell. The die 6 is used to process lithium battery steel shells. A second servo motor 12 is located at the middle position of the bottom inner side of the frame 1 near the front end. The output end of the second servo motor 12 is fixedly connected to the middle position of the bottom end of the workstation plate 5. During the stamping process, the second servo motor 12 drives the workstation plate 5 to rotate at a fixed angle and cooperate with the hydraulic cylinder 9 to stamp cylindrical steel shells one by one. An annular stabilizing groove 15 is provided at the bottom edge of the workstation plate 5. A fixed vertical plate 17 is provided at the front end of the bottom inner side of the frame 1. An annular stabilizing rail 16 is provided between the top ends of the fixed vertical plate 17. The stabilizing groove 15 is nested on the top end of the outside of the stabilizing rail 16 and can slide on the stabilizing rail 16. When the workstation plate 5 rotates, the stabilizing groove 15 rotates on the stabilizing rail 16 to ensure the stability of the workstation plate 5 and the die 6.

[0024] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, an isolation cover 2 is provided on the outer side of the workstation plate 5. The bottom of the isolation cover 2 is rotatably connected to the bottom of the inner side of the frame 1. A pick-and-place slot 4 is provided on the top of the front end of the isolation cover 2. A first servo motor 11 is provided at the rear end of the frame 1 near the bottom. A transmission gear 14 is provided at the output end of the first servo motor 11. A ring-shaped rack 3 is provided on the bottom of the outer side of the isolation cover 2. The rack 3 and the transmission gear 14 are on the same horizontal plane and mesh with each other. During the stamping operation, the first servo motor 11 drives the transmission gear 14 to rotate the meshing rack 3 by 180°, which rotates the pick-and-place slot 4 to face the inner side of the frame 1. The isolation cover 2 isolates the stamping work space to avoid the steel shell or punch 10 breaking and splashing due to stamping errors, which may cause injury to the operator. An explosion-proof transparent cover 7 is provided on the inner side wall of the isolation cover 2. At the same time, the operator can monitor the stamping process through the explosion-proof transparent cover 7, which effectively improves the safety of the device when stamping the cylindrical steel shell of the battery and reduces the probability of production safety accidents.

[0025] When in use, the pre-formed steel shell is placed inside the mold 6 through the pick-and-place slot 4. Then, the first servo motor 11 is started to drive the transmission gear 14 to rotate the rack 3 that meshes with it by 180°. This rotates the pick-and-place slot 4 to face the inside of the frame 1. The stamping work space is isolated by the isolation cover 2. During the stamping process, the stamping process can be monitored through the explosion-proof transparent cover 7. After one round of stamping is completed, the first servo motor 11 drives the transmission gear 14 to rotate the rack 3 that meshes with it by 180° to adjust the pick-and-place slot 4 to face forward so that workers can pick up and place the steel shell.

[0026] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, a disassembly and replacement assembly is provided between the bottom of the hydraulic cylinder 9 and the top of the punch 10. The disassembly and replacement assembly includes a mounting sleeve 8, which is located at the top of the punch 10. An assembly head 19 is provided at the bottom of the hydraulic cylinder 9. The mounting sleeve 8 is sleeved on the outside of the assembly head 19. Cavities 21 are provided at both ends inside the assembly head 19, and the cavities 21 are symmetrically arranged inside the assembly head 19. Connecting holes 23 are provided at both ends inside the mounting sleeve 8, and the connecting holes 23 are symmetrically arranged inside the mounting sleeve 8. A return spring 22 is provided at one end of the cavity 21, and a connecting piece 24 is provided inside the cavity 21 at one end of the return spring 22. One end of the connecting piece 24 is provided with a stabilizing lever 20. One end of the stabilizing lever 20 passes through the interior of the connecting hole 23. The mounting sleeve 8 is fitted onto the outside of the assembly head 19. The stabilizing lever 20 is pushed through the interior of the connecting hole 23 by the return spring 22, so as to fix the mounting sleeve 8 on the outside of the assembly head 19, thereby stabilizing the punch 10 to the bottom of the hydraulic cylinder 9. The mounting sleeve 8 can be removed by pressing the stabilizing lever 20 out of the connecting hole 23, thereby disassembling the punch 10. This achieves the purpose of conveniently and quickly replacing the punch 10 to be used for stamping operations of cylindrical steel shells of different sizes.

[0027] Working principle: When using the lithium battery cylindrical steel shell stamping device, firstly, the mounting head 13 is fixed inside the positioning groove 18 by threaded connection, thus securing the mold 6 in the designated position on the workstation plate 5. Then, the stabilizing lever 20 is pressed and retracted into the cavity 21. Next, the mounting sleeve 8 is fitted onto the outside of the assembly head 19, and the connecting hole 23 is adjusted to align with the stabilizing lever 20. Simultaneously, the return spring 22 pushes the stabilizing lever 20 through the connecting hole 23, thus securing the punch 10 to the bottom of the hydraulic cylinder 9. After the pre-made cylindrical steel shell is placed into the mold 6 through the pick-and-place slot 4, the first servo motor 11 is started to drive the transmission gear 14, causing the meshing rack 3 to rotate 180°, thus opening the pick-and-place slot. 4. Rotate to face the inside of the frame 1, and isolate the stamping work space through the isolation cover 2. Then, start the hydraulic cylinder 9 to lower and drive the punch 10 to stamp and form the lithium battery steel shell. During the stamping process, the second servo motor 12 drives the station plate 5 to rotate at a fixed angle and cooperate with the hydraulic cylinder 9 to stamp and form cylindrical steel shells one by one. At the same time, the stabilizing slide 15 rotates on the stabilizing rail 16 to ensure the stability of the station plate 5 and the mold 6. During the stamping process, the technician can monitor the stamping process through the explosion-proof transparent cover 7. After one round of stamping, the first servo motor 11 drives the transmission gear 14 to drive the meshing rack 3 to rotate 180° to adjust the pick-and-place slot 4 to face forward, so that the worker can pick up and place the steel shell for the next stamping process, thus carrying out safe and efficient cylindrical steel shell stamping processing.
