Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and specifically relates to a lithium battery casing stamping die device with a cleaning function. Background Technology

[0002] A lithium battery casing stamping die device with cleaning function is a piece of equipment that integrates automatic cleaning functionality into a traditional stamping die. It is mainly used for high-precision forming of lithium battery casings. Its core principle is to use a built-in cleaning mechanism to remove aluminum shavings, oil stains, and other residues generated during the stamping process in real time, preventing impurities from embedding in the die cavity or scratching the workpiece surface, thereby ensuring the dimensional accuracy and surface quality of the casing. This cleaning-functional lithium battery casing stamping die device not only improves product yield but also reduces the frequency of manual cleaning, lowering the risk of production interruptions due to downtime maintenance.

[0003] Chinese Patent Publication No. CN222288459U relates to the technical field of lithium battery casing stamping, and in particular to a lithium battery casing stamping apparatus. This apparatus, by incorporating a blanking mechanism and a cleaning mechanism, allows for simultaneous blanking and cleaning of the equipment surface during the casing stamping process, thereby improving production quality. The apparatus includes a punch mechanism, a die mechanism, an adjusting mechanism, four sets of limiting mechanisms, a blanking mechanism, and a cleaning mechanism. The die mechanism is installed at the lower end of the punch mechanism, the adjusting mechanism at the upper end of the punch mechanism, the four sets of limiting mechanisms on the adjusting mechanism, the blanking mechanism at the upper end of the punch mechanism, and the cleaning mechanism on the blanking mechanism. The punch mechanism performs shaping, the die mechanism performs pressing, the adjusting mechanism lifts the material, the limiting mechanisms limit movement, the blanking mechanism performs blanking, and the cleaning mechanism performs cleaning.

[0004] In practical use, this utility model can clean the dust and debris generated during processing through the built-in cleaning components. However, the existing lithium battery casing stamping die devices with cleaning functions generally have a simple structural design and rely on a single cleaning brush to complete the cleaning operation. This makes it difficult to completely remove small particles or edge residues on the surface of the punch. Over time, this can easily lead to problems such as scratches on the die surface and deviations in workpiece dimensions, which in turn affect the stamping accuracy of the lithium battery casing. As a result, the practicality of lithium battery casing stamping die devices with cleaning functions is somewhat lacking. Utility Model Content

[0005] This invention proposes a lithium battery casing stamping die device with cleaning function to solve the problem of the difficulty in thoroughly cleaning dust and debris in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery casing stamping die device with a cleaning function, comprising:

[0007] Upper template and lower template;

[0008] An erection board is set at the bottom end of the upper template. The bottom end of the erection board is provided with a protruding module. The upper end of the lower template is provided with a base plate. The upper end of the base plate is provided with a concave mold groove that matches the protruding module.

[0009] Two fixing plates are respectively set on both sides of the upper end of the lower template. Both fixing plates are U-shaped. The bottom sides of the erection plate are provided with mounting sleeves that are adapted to the fixing plates.

One end of each of the two positioning plates is provided with a guide shaft that matches the guide groove. The two guide shafts are located in the two guide grooves and are slidably connected to the side wall of the guide groove.

[0013] To thoroughly and effectively clean the convex module, a filter box is provided at the upper end of the mounting plate, and a dust collection groove is provided in each of the two dust collection plates. Multiple dust collection holes are provided through the two dust collection grooves on the side near the convex module.

This utility model, through the cleaning brush set on one side of the two dust suction plates, as well as the dust suction groove and multiple dust suction holes, can clean the dust and debris attached to the surface of the protruding module in real time when the lithium battery casing stamping mold device is running. The dust suction groove and dust suction holes can quickly absorb the dust and debris through negative pressure, realizing a seamless connection of cleaning actions. It not only covers the corner areas that are difficult to reach by traditional devices, but also greatly reduces the interference of small particles on the mold precision through the dual effects of dynamic cleaning and static adsorption. This allows the lithium battery casing to maintain higher dimensional consistency and surface smoothness during the stamping process, making the lithium battery casing stamping mold device with cleaning function more practical.

[0020] 2. This utility model, through the top plate and abutment rod set in the die groove, and the limiting plate and abutment groove in the bottom plate, can push the top plate to rise smoothly when the limiting plate moves, automatically ejecting the lithium battery casing in the die groove. This not only avoids the casing deformation or surface damage that may be caused by traditional manual removal, but also greatly shortens the production downtime through the continuous ejection action. This makes the lithium battery casing stamping die device with cleaning function not only maintain efficient cleaning function, but also further improve the ease of operation.

[0028] Example 1:

[0029] Please see Figure 1-5 This utility model provides a lithium battery casing stamping die device with a cleaning function, comprising:

[0030] Upper template 1 and lower template 2;

[0031] Erection plate 3 is set at the bottom of the upper template 1. The bottom of the erection plate 3 is provided with a protruding module 4.

The two guide shafts 13 are located in the two guide slots and are slidably connected to the side wall of the guide slot. When the mounting sleeve 8 moves up and down with the mounting plate 3, it will drive the positioning plate 12 and the guide shaft 13 to move up and down. With the inclined guide slot, the mounting sleeve 8 can drive the positioning plate 12, the suction plate 9 and the cleaning brush 10 to move in the horizontal direction while moving up and down, so as to achieve convenient and effective cleaning of the protruding module 4.

[0036] Specifically, such as Figure 2 As shown, a filter box 14 is provided on the upper end of the mounting plate 3, and a dust collection groove is provided in each of the two dust collection plates 9. Multiple dust collection holes 22 are provided through the two dust collection grooves near the side of the convex module 4.

[0040] Example 2:

[0041] Please see Figure 1-5 This utility model provides a lithium battery casing stamping die device with a cleaning function, comprising:

[0042] Upper template 1 and lower template 2;

[0043] Erection plate 3 is set at the bottom of the upper template 1. The bottom of the erection plate 3 is provided with a protruding module 4. The upper end of the lower template 2 is provided with a base plate 5. The upper end of the base plate 5 is provided with a concave mold groove 6 that matches the protruding module 4.

[0044] Two fixing plates 7 are respectively set on the upper sides of the lower template 2. Both fixing plates 7 are set in a "U" shape. The bottom sides of the erection plate 3 are provided with mounting sleeves 8 that are adapted to the fixing plates 7. The two mounting sleeves 8 are respectively fitted on the outside of the two fixing plates 7.

[0045] Two rectangular slots are respectively opened on one side of the two mounting sleeves 8. Each of the two rectangular slots is equipped with a dust suction plate 9, and each of the two dust suction plates 9 is equipped with a cleaning brush 10 at the bottom.

[0046] Specifically, such as Figure 3 As shown, a limiting groove is provided at the bottom end of the base plate 5, and a matching limiting plate 18 is provided in the limiting groove. The size of the limiting plate 18 is larger than that of the rectangular groove. A matching top plate 19 is provided at the bottom end of the cavity groove 6. An abutting rod 20 is provided at the bottom end of the top plate 19. The bottom end of the abutting rod 20 is arc-shaped and extends into the limiting groove. An abutting groove matching the abutting rod 20 is provided at the upper end of the limiting plate 18, and the bottom end of the abutting rod 20 is located in the abutting groove.

[0047] Through its design, when the mounting sleeve 8 on one side moves upward and separates from the limiting plate 18, the limiting plate 18 will drive the abutment groove to move outward, thereby pushing the abutment rod 20 out of the abutment groove. The abutment rod 20 will drive the top plate 19 to move upward, pushing out the lithium battery casing in the cavity groove 6, saving people the time and manpower to remove it manually. The size of the limiting plate 18 is larger than the rectangular groove, which can prevent it from entering the rectangular groove.

[0048] Specifically, such as Figure 2 As shown, one end of the limiting plate 18 is arc-shaped and abuts against the mounting sleeve 8 on one side.

[0049] See Figure 1-5When using a lithium battery casing stamping die device with a cleaning function, the lithium battery casing needs to be placed on the upper end of the base plate 5. Then, by activating multiple cylinders 11, the mounting plate 3 and the protruding module 4 are moved downwards. This, in conjunction with the die groove 6 at the upper end of the base plate 5, stamps the lithium battery casing. When the mounting plate 3 moves upwards, it moves the two mounting sleeves 8. The two mounting sleeves 8 then move the two positioning plates 12 and the two guide shafts 13 respectively, causing the two guide shafts 13 to move within two inclined guide grooves. This allows the two positioning plates 12 to drive the suction... Dust plate 9 and cleaning brush 10 move toward the convex module 4. The two cleaning brushes 10 clean the dust and debris at the bottom of the convex module 4. During the cleaning process, the pump body 16 is activated. The air extraction end of the pump body 16 extracts air from the filter box 14. The filter box 14 can extract air from the two dust suction plates 9 through two telescopic hoses 15. Thus, the dust and debris on the surface of the convex module 4 can be cleaned through multiple dust suction holes 22, which improves the cleaning effect and ensures the precision of the lithium battery casing stamping die device with cleaning function in the stamping process of the lithium battery casing.
