[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] like Figures 1-5As shown, this application provides a double-row linkage battery casing stretching equipment, including a stamping and stretching assembly 1. The stamping and stretching assembly 1 realizes the stamping and stretching forming of the battery casing. The forming accuracy and stability are ensured by hydraulic drive and guiding structure, and it supports efficient production of double-row workstations. The stamping and stretching assembly 1 includes a stamping shell 11, which serves as the main frame of the battery casing stretching equipment and provides structural support and installation foundation for the entire stamping and stretching process. A hydraulic push rod 12 is bolted to the top of the stamping shell 11. The hydraulic push rod 12 is powered by an externally connected hydraulic system and completes the stamping and stretching forming of the metal sheet. Its thrust and stroke can be controlled by the hydraulic system. A stamping seat 13 is bolted to the output end of the hydraulic push rod 12. The stamping seat 13 transmits the power of the hydraulic push rod 12. Two sets of upper dies 14 are bolted to the bottom of the stamping seat 13. The upper dies 14 contact the metal sheet and realize the shape forming of the battery casing under the drive of the hydraulic push rod 12.

[0030] Two sets of guide rods 15 are bolted to both sides of the stamping shell 11, and two sets of guide sleeves 16 are bolted to both sides of the stamping seat 13. The guide sleeves 16 can move axially along the rod body of the guide rods 15. During the sliding process of the guide sleeves 16 on the outer wall of the guide rods 15, the horizontal displacement of the stamping seat 13 is effectively restricted, so that the stamping seat 13 can only move vertically, ensuring that the upper mold 14 is aligned with the metal sheet, and reducing the deformation of the workpiece or wear of the mold caused by stamping deviation.

[0031] A support 17 is fixed at the bottom of the stamping shell 11. The support 17 ensures the stability of the overall structure of the battery shell stretching equipment. A worktable 18 is bolted to the upper end of the support 17. The worktable 18 provides a working plane for stamping. Two sets of lower dies 19 are bolted to the upper part of the worktable 18. The lower dies 19 correspond to the upper dies 14 in a horizontal position and form two parallel stretching and stamping stations. At the same time, the lower dies 19 and the upper dies 14 cooperate with each other to complete the stretching and forming of the battery shell.

[0032] like Figures 2-5As shown, an ejector assembly 2 is installed inside the support 17. The ejector assembly 2 is driven by power to eject the stamped battery casing, avoiding the workpiece from being stuck in the mold, improving production efficiency and reducing manual operation. The ejector assembly 2 includes multiple sets of fixing rings 21 fixed to the top inside the support 17. The fixing rings 21 are circular rings made of stainless steel. Springs 22 are fixed on each fixing ring 21. A connecting frame 23 is fixed to one end of the spring 22. The spring 22 keeps the connecting frame 23 moving downward. A push rod 24 is fixed to the upper part of the connecting frame 23. The spring 22 is sleeved on the outer circumference of the push rod 24, and the central axes of the two are completely coincident. Under the action of power, the spring 22 is compressed and stores energy. After the power is removed, the potential energy is released, and the connecting frame 23 drives the push rod 24 to reset, ensuring that the next ejection action is smooth.

[0033] Two sets of ejector grooves 191 are provided on the inner bottom surface of the lower mold 19. The upper ends of the ejector rods 24 pass through the support 17 and the worktable 18 and extend into the ejector grooves 191. A top plate 25 is installed by bolts. The top plate 25 is made of stainless steel and aluminum alloy. When ejecting, it contacts the two sides of the bottom of the workpiece, increasing the area of ​​the ejector force and reducing the occurrence of local stress deformation of the formed battery case. This ensures that the workpiece is smoothly removed from the lower mold 19. During stamping, the top plate 25 is located in the ejector grooves 191 to avoid interfering with the forming of the sheet metal. During ejection, it provides ejection space for the top plate 25 to ensure that the formed battery case is successfully demolded.

[0034] like Figures 2-6 As shown, a drive assembly 3 is installed on the worktable 18. The drive assembly 3 provides power to the top material assembly 2, enabling the top material assembly 2 to perform the unloading operation of the battery case. The drive assembly 3 includes two sets of limiting sleeves 31 bolted to the worktable 18. A long rod 32 is slidably connected in the limiting sleeves 31. The limiting sleeves 31 provide vertical limiting and guidance for the long rod 32, ensuring that the long rod 32 does not deviate when it moves up and down with the stamping seat 13. The upper end of the long rod 32 is bolted to the bottom of the stamping seat 13, and the lower end of the long rod 32 extends into the support 17 and is fixed with a drive frame 33. The long rod 32 transmits the movement of the stamping seat 13 to the drive frame 33, so that the drive frame 33 moves synchronously, thereby realizing the linkage control between the top material assembly 2 and the stamping action.

[0035] A central rod 34 is fixed in the middle of each of the multiple connecting frames 23. The drive frame 33 has an arc groove 35 in the middle that matches the central rod 34, and the central rod 34 is located above the arc groove 35. Specifically, when the drive frame 33 moves upward, the arc groove 35 fits with the central rod 34 and drives the connecting frame 23 to move upward against the elastic force of the spring 22. This, in turn, drives the top rod 24 and the top plate 25 to push the stamped battery case upward. At the same time, the spring 22 is compressed to store energy. When the drive frame 33 moves downward, the arc groove 35 disengages from the central rod 34, the spring 22 releases its elastic potential energy, pushes the connecting frame 23 downward, and causes the top rod 24 to drive the top plate 25 to reset, making way for the stamping process.

[0036] Working principle: When the equipment is running, the hydraulic system drives the hydraulic push rod 12, which drives the stamping seat 13 to move vertically along the guide rod 15. The two sets of upper dies 14 at the bottom of the stamping seat 13 correspond to the two sets of lower dies 19 on the worktable 18, forming a double-row stamping station, which can stretch and form two metal sheets at the same time. At the same time, the sliding of the guide sleeve 16 on the guide rod 15 restricts the horizontal displacement of the stamping seat 13, ensuring that the upper and lower dies are accurately aligned and reducing stamping deviation.

[0037] After stamping is completed, the hydraulic push rod 12 drives the stamping seat 13 to move upward, and the long rod 32 drives the drive frame 33 to move upward. At this time, the arc groove 35 fits with the middle rod 34, and the drive frame 33 pushes the middle rod 34 to move upward, which drives the connecting frame 23 to move upward against the elastic force of the spring 22, so that the push rod 24 and the top plate 25 push the stamped battery case upward. At the same time, the spring 22 is compressed and stored energy. After the battery case is pushed out of the lower mold 19, the operator can take it away.

[0038] Subsequently, the stamping seat 13 descends. When the arc groove 35 and the intermediate rod 34 initially disengage, the hydraulic push rod 12 is closed, causing its output end to temporarily stop descending. The spring 22 releases its elastic potential energy, pushing the connecting frame 23 downward and causing the top rod 24 and top plate 25 to reset. At this time, the spring 22 is in its natural state, and the top plate 25 returns to the top material groove 191 to make way for the next stamping. When the operator places the material to be stretched, the hydraulic push rod 12 is restarted, causing its output end to drive the stamping seat 13 downward, realizing the stretching and forming of the battery case. This cycle is repeated to complete the continuous stamping and automatic top material ejection of the battery case, improving production efficiency and reducing manual intervention.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. 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.
