Description

Technical Field

[0001] This utility model relates to the technical field of battery production and processing equipment, and in particular to a hole-opening device for processing aluminum casings of batteries. Background Technology

[0002] Aluminum battery casings are widely used in modern electronic equipment and new energy fields due to their excellent heat dissipation, lightweight properties, and metallic shielding characteristics. These casings are typically formed by die stamping and stretching processes to create a three-dimensional structure with a specific contour, such as complex geometries with curved top surfaces, curved sidewalls, or internal reinforcing ribs.

[0003] In the assembly and use of batteries, holes need to be made in the formed casing for purposes such as cable passage, interface installation, pressure relief, or heat dissipation. Currently, the mainstream process for making these holes is to use specialized punching equipment. This type of equipment typically consists of a horizontal punching table and a vertically moving punch. A flat pressure plate (or pressure ring) is installed at the end of the punch, which is used to clamp the workpiece before punching to prevent the material from moving or deforming during the shearing process.

[0004] However, this traditional punching solution designed for planar workpieces reveals a significant technical flaw when applied to pre-formed battery casings: both the stamping table and the pressure plate on the punch are rigid horizontal structures, which cannot adapt to the inherent three-dimensional curved shape of the casing.

[0005] Specifically, when an operator places a battery casing with a curved surface onto a horizontal stamping table, the casing only contacts the table surface through a few high points, leaving a large area of ​​unsupported space. This results in unstable positioning and inconsistent reference points. More seriously, when the punch presses down, its horizontal pressure plate at the end contacts the protruding parts of the casing with immense pressure. Due to the small contact area and high pressure, indentations are easily left on the casing surface, and can even cause plastic dents or distortions to the beautifully curved surface.

[0006] This secondary deformation caused by the mismatch between tooling and product shape not only damages the product's appearance integrity but may also affect the overall assembly accuracy of the battery. In extreme cases, it can even alter the wall thickness distribution of the casing, posing a potential threat to its structural strength and heat dissipation performance. Furthermore, applying uneven clamping forces to curved workpieces can easily lead to uneven material flow during punching, causing increased burrs, dimensional deviations, and even tearing, among other quality problems.

[0024] 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. 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.

[0025] Please see the appendix Figure 1-5This embodiment discloses a hole-opening device for processing aluminum casings of batteries: It includes a fixed platform 1, a support 2 on the fixed platform 1, a punching rod 3 slidably connected to the support 2, a punch 4 fixedly connected to the bottom of the punching rod 3, a self-adjusting pressure rod assembly 5 on the outside of the punch 4, a punching table 6 below the punch 4, a support rod assembly 7 and a blanking hole 8 fixedly connected to the punching table 6, and clamping blocks 9 on both sides of the punching table 6, which are slidably connected to the fixed platform 1. The self-adjusting rod assembly includes multiple sets of pressure blocks 501, which are evenly distributed around the punch 4. A first guide rod 502 is connected to each pressure block 501 to guide its vertical movement. The first guide rod 502 is slidably connected to a guide plate 503. A limiting piece 505 is located at the upper end of the first guide rod 502 to prevent it from disengaging from the guide plate 503. A spring 504 is sleeved on the first guide rod, and the spring 504 exerts a downward elastic force on the pressure block 501.

[0026] In specific operation: During the punching process, the drive component inside the bracket 2 drives the punching rod 3 to move downward. The downward movement of the punching rod 3 drives the punch 4, the pressure block 501, and the guide plate 503 to move downward synchronously. In the initial state, the lowest point of the pressure block 501 is lower than the lowest point of the punch 4. During the downward movement, the pressure block 501 contacts the aluminum shell first and presses the aluminum shell. Each pressure block 501 has an independent spring 504 on its first guide rod 502. When dealing with curved surfaces, the different deformations of the springs 504 adapt to the curved surface of the aluminum shell, ensuring the fit between the pressure block 501 and the aluminum shell. After the pressure block 501 is fixed, the punch 4 squeezes and punches the aluminum shell to complete the punching action.

[0027] The support rod assembly 7 includes a load-bearing rod 701. A threaded hole 702 is provided on the stamping table 6, and the load-bearing rod 701 is threadedly connected to the threaded hole 702. Fixing nuts 703 are provided on both the upper and lower sides of the threaded hole 702, and are threadedly connected to the load-bearing rod 701. The bottom of the load-bearing rod 701 has a long threaded groove, and the load-bearing rod 701 is threadedly fixed to the threaded hole 702. The stamping table 6 has multiple sets of densely threaded holes 702. During the installation of the load-bearing rod 701, the height of the load-bearing rod 701 can be adjusted by controlling the screw depth between the load-bearing rod 701 and the threaded hole 702. The height of different load-bearing rods 701 can be adjusted according to the curvature of the aluminum plate, thereby ensuring good support of the load-bearing rod 701 for the aluminum shell. In addition, there are two fixing nuts 703 on the load-bearing rod 701, located on the upper and lower sides of the stamping table 6 respectively. The fixing nuts 703 serve to fix the position of the load-bearing rod 701.

[0028] The fixed platform 1 is provided with a waste trough 10, which is located below the discharge hole 8. Adjustment platforms 11 are provided on both sides of the waste trough 10. The two adjustment platforms 11 have the same structure, and the telescopic rods 12 inside them move synchronously. The synchronous movement of the two telescopic rods 12 ensures that the two clamps 9 play a role in centering and fixing the aluminum shell.

[0029] A slide table 13 is fixedly connected below the adjusting platform 11. A second guide rod 14 is slidably connected to the slide table 13, guiding its left and right movement. The slide table 13 is used to adjust the position of the adjusting platform 11 relative to the stamping table 6 over a wide range. The position of the slide table 13 is adjusted by rotating the adjusting screw 16, which is threadedly connected to the slide table 13. A third guide rod 17 is slidably connected to the adjusting platform 11 and is fixedly connected to the clamping block 9. A slide rail 18 is provided on the fixed platform 1, and the bracket 2 is slidably connected to the slide rail 18.

[0030] Working principle: During use, the aluminum battery casing is placed on the stamping table 6. The sliding table 13 is moved by the adjusting screw 16, which in turn drives the adjusting table 11 and the clamping block 9 to clamp the workpiece. The load-bearing rod 701 of the support rod assembly 7 can be adjusted in height according to the curved surface of the casing to ensure uniform support. When the stamping rod 3 moves downward, the pressure block 501 of the self-adjusting pressure rod assembly 5 first contacts the curved surface of the casing and self-adjusts under the action of the spring 504 to avoid local stress concentration. After the punch 4 completes the punching, the scrap material falls into the scrap trough 10 through the discharge hole 8 for collection.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 the present utility model should be included within the protection scope of the present utility model.
