Detailed Implementation

[0025] 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.

[0026] Reference Figures 1-6 A multi-station stretching and forming equipment for cylindrical battery aluminum shells includes a frame 1, a U-shaped frame 2 fixed to the top of the frame 1 by bolts, and a multi-station stamping assembly on the top of the U-shaped frame 2.

[0027] The multi-station stamping assembly includes a hydraulic cylinder 3, which is fixed to the top of the U-shaped frame 2 by bolts. One end of the hydraulic rod of the hydraulic cylinder 3 passes through the U-shaped frame 2 and is fixed to a movable frame 4 by bolts. Multiple U-shaped blocks 13 are slidably connected to the bottom of the movable frame 4, and the U-shaped blocks 13 are fixed to the movable frame 4 by detachable bolts. A stamping head 14 is fixed to the bottom of the U-shaped blocks 13 by bolts.

[0028] The top of the frame 1 has multiple mounting slots 9. The lower mold 6 is fixed in the mounting slot 9 by bolts. Multiple pre-cut aluminum plates to be stamped are placed on the lower mold 6. The hydraulic cylinder 3 extends to move the moving frame 4 downward along the guide rod 5, thereby causing the U-shaped block 13 to drive the stamping head 14 downward, so that the stamping head 14 enters the cavity of the lower mold 6. At this time, the stamping head 14 applies external force to the aluminum plate on the lower mold 6, thereby realizing the stretching and forming of the aluminum plate.

[0029] The top of the frame 1 is provided with multiple sliding grooves 10, and the multiple sliding grooves 10 are all connected to the mounting grooves 9 above them. The lifting frame 11 is slidably connected in the multiple sliding grooves 10, and the bottom end of the lifting frame 11 is fixed with a sliding column 12 by bolts.

[0030] A fixed plate 7 is bolted to one side of the frame 1. Multiple slide rods 21 are movably inserted into the fixed plate 7. One end of the slide rods 21 passes through the fixed plate 7 and is bolted to a pull frame 8. A movable plate 15 is bolted between the other ends of the slide rods 21. A spring 17 is sleeved on the outside of the slide rods 21, and the two ends of the spring 17 are fixed to the movable plate 15 and the slide rods 21 respectively. Multiple guide frames 20 are bolted to one side of the movable plate 15, and the slide column 12 slides along the groove of the guide frame 20.

[0031] After processing, the operator pulls the pull frame 8, causing the slide rod 21 to move the moving plate 15, and the spring 17 to contract. At the same time, the moving plate 15 moves the guide frame 20 inward. At this time, the position of the slide column 12 in the groove of the guide frame 20 changes. Under the action of the squeezing force of the guide frame 20, the slide column 12 moves upward with the inclination of the groove of the guide frame 20, which in turn causes the lifting frame 11 to move upward along the slide groove 10. The lifting frame 11 pushes the workpiece stretched and formed in the lower mold 6 upward, making it easier for the operator to take it out. Then, the stamping mold is processed in subsequent steps.

[0032] In this utility model, it should be noted that two guide rods 5 are fixed to both sides of the U-shaped frame 2 by bolts, and the movable frame 4 slides along the guide rods 5. The guide rods 5 can guide the movable frame 4 so that it can move stably and avoid tilting during the movement.

[0033] The top inner wall of the frame 1 is fixed with a guide rail 19 by bolts, and the movable plate 15 is slidably connected to the guide rail 19. The guide rail 19 can guide the movable plate 15 so that it can move stably.

[0034] Multiple sliding sleeves 18 are fixed to the inner side of the fixed plate 7 by bolts, and the sliding rod 21 moves along the inside of the sliding sleeve 18. The sliding sleeve 18 can guide the sliding rod 21. The slide groove 10 is connected to the cavity of the lower mold 6. The diameter of the top protruding ring of the lifting frame 11 is larger than the diameter of the top of the slide groove 10 to prevent the lifting frame 11 from moving out of the slide groove 10.

[0035] A baffle 16 is bolted to the side of the top of the frame 1, and the movable plate 15 can contact the baffle 16. The baffle 16 can restrict the movement of the movable plate 15 and prevent the movable plate 15 from moving too much when it is reset.

[0036] The working principle of this utility model is as follows: When aluminum plates need to be stretched and formed, multiple processed aluminum plates are first placed on the lower mold 6. Then, the hydraulic cylinder 3 is activated, and the hydraulic cylinder 3 extends to move the moving frame 4 downward along the guide rod 5. This causes the U-shaped block 13 to drive the punch head 14 downward, so that the punch head 14 enters the cavity of the lower mold 6. At this time, the punch head 14 applies external force to the aluminum plate on the lower mold 6, thus stretching and forming the aluminum plate. After processing, the operator pulls the pull frame 8, causing the slide rod 21 to drive the moving plate 15 to move along the guide rail 19. The spring 17 contracts, and the sliding sleeve 18 guides the slide rod 21. At the same time, the moving plate 15 moves, causing the guide frame 20 to move inward. At this time, the position of the slide column 12 in the groove of the guide frame 20 changes, so that the slide column 12 moves upward along the inclination of the groove of the guide frame 20. This causes the lifting frame 11 to move upward along the slide groove 10, so that the lifting frame 11 pushes the stretched and formed workpiece in the lower mold 6 upward, making it easier for the operator to remove it.

[0037] 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.
