Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to an adaptive stamping die suitable for boxes of different specifications. Background Technology

[0002] A battery casing stamping die is a specialized tooling device used to manufacture battery casings through a stamping process. In fields such as new energy vehicles and energy storage equipment, the battery casing, as the core load-bearing and protective component of the battery pack, needs to possess high structural strength, dimensional accuracy, and sealing performance.

[0003] Traditional stamping dies have fixed cavity dimensions. When different specifications of boxes need to be produced, the entire die needs to be replaced. This not only takes a long time and is labor-intensive, increasing production preparation time and reducing production efficiency, but also requires the storage of dies of various specifications, resulting in high die storage costs and making it difficult to meet the flexible production needs of multiple varieties and small batches of boxes. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an adaptive stamping die suitable for boxes of different specifications.

[0005] This utility model is achieved using the following technical solution: an adaptive stamping die suitable for boxes of different specifications, including a lower base plate, an upper base plate on the top of the lower base plate, a lower die assembly capable of changing the internal space size on the top of the lower base plate, an upper die assembly capable of changing the stamping position on the bottom side of the upper base plate, the lower die assembly including a stamping box fixedly installed on the lower base plate, adjustment ports on both sides of the stamping box, multiple adjustment blocks arranged in an array inside the two adjustment ports, movable boxes fixedly installed on both sides of the stamping box, and movable ports on the side of the two movable boxes near the stamping box, with one side of each adjustment block passing through the adjacent movable port and extending into the interior of the adjacent movable box.

[0006] Through the above technical solution, the adjusting block can move within the adjusting port of the stamping box and the moving port of the moving box, changing the internal space size of the stamping box, thereby adapting to the production of boxes with different width specifications, without the need to replace the entire lower mold assembly, thus improving the versatility of the mold.

[0007] As a further improvement to the above solution, the bottom of the inner cavity of each of the two movable boxes is provided with a plurality of first fixing slots arranged in an array, the top of each of the two movable boxes is fixedly installed with a baffle, each of the two baffles is provided with a plurality of second fixing slots that penetrate through itself and are arranged in an array, a limiting plate in the shape of an octagon is fixedly installed on one side of each adjusting block, a fixing plate is slidably installed inside each limiting plate, and both ends of each fixing plate extend into the interior of the adjacent first fixing slot and second fixing slot.

[0008] With the above technical solution, the two ends of the fixing plate are respectively inserted into the first fixing groove and the second fixing groove, which can fix the adjusting block in the current position, prevent the adjusting block from shifting during the stamping process, and ensure the stability of the internal space dimensions of the stamping box. By selecting the first fixing groove and the second fixing groove at different positions, the adjusting block can be fixed in different positions to meet different space adjustment needs. Since the size of the battery box is specified, it is only necessary to set it according to the specified size, and it is not necessary to fix it in any position.

[0009] As a further improvement to the above solution, multiple first sliding grooves arranged in an array are provided on both sides of the bottom of the inner cavity of the stamping box, and multiple second sliding grooves arranged in an array are provided on the bottom of the inner cavities of the two movable boxes. Each first sliding groove is connected to the adjacent second sliding groove, and a first sliding block is fixedly installed on the bottom side of each adjusting block. Each first sliding block is located inside the adjacent first sliding groove.

[0010] Through the above technical solution, the first sliding block slides in the first sliding groove and the second sliding groove, providing guidance for the movement of the adjusting block, ensuring the smoothness and straightness of the movement of the adjusting block, and avoiding deviation when the adjusting block moves.

[0011] As a further improvement to the above solution, the upper mold assembly includes a lower pressure box fixedly installed on the bottom side of the upper base plate. The top of the inner cavity of the lower pressure box is provided with a plurality of third sliding grooves arranged in an array. Each of the two ends of the inner cavity of each third sliding groove is slidably installed with a second sliding block, and each of the second sliding blocks is fixedly installed with a lower pressure column on its bottom side.

[0012] Through the above technical solution, the second sliding block slides in the third sliding groove, which can drive the lower pressure column to move and change the position of the lower pressure column, thereby adapting to the stamping requirements of different specifications of boxes, enabling the upper mold assembly to perform stamping processing on different positions, and improving the adaptability of the upper mold assembly.

A rubber ring is fixedly installed on one side of each rotating block, and one side of each rubber ring is in contact with the lower pressure box.

[0014] Through the above technical solution, rotating the rotating block can drive the bidirectional threaded rod to rotate. Since the second sliding block is threaded on the bidirectional threaded rod, the rotation of the bidirectional threaded rod can drive the two second sliding blocks to move in opposite directions or away from each other along the third sliding groove, so as to achieve precise adjustment of the position of the pressing column. The rubber ring is in contact with the pressing box, and the friction force can limit the rotating block to prevent the bidirectional threaded rod from rotating during the stamping process, thus ensuring the stability of the position of the pressing column.

[0015] As a further improvement to the above solution, each of the first sliding block and the second sliding block is arranged in a "T" shape, and the length and width of the lower pressure box are both greater than the length and width of the stamping box.

[0016] Through the above technical solution, the first and second sliding blocks with the "T" shape can prevent them from disengaging from the corresponding sliding grooves, ensuring the reliability of the sliding process; the length and width of the lower pressure box are greater than the length and width of the stamping box, ensuring that the stamping range of the upper mold assembly can cover the stamping area of ​​the lower mold assembly, and preventing excess lower pressure columns from contacting the stamping box and affecting normal stamping.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features adjustable lower and upper mold assemblies. The lower mold assembly changes the internal space of the stamping box by adjusting the movement of the adjusting block, while the upper mold assembly moves the lower pressing column to change the stamping position via a bidirectional threaded rod. This enables the mold to adapt to different specifications of boxes without requiring a complete mold replacement, reducing mold change time, improving production efficiency, and lowering mold storage costs. It also meets the flexible production needs of multiple varieties and small batches of boxes. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Please combine Figures 1-7 An adaptive stamping die suitable for boxes of different specifications in this embodiment includes a lower base plate 1, an upper base plate 2 on the top of the lower base plate 1, a lower die assembly that can change the size of the internal space on the top of the lower base plate 1, and an upper die assembly that can change the stamping position on the bottom side of the upper base plate 2.

[0030] The lower mold assembly includes a stamping box 301 fixedly mounted on the lower base plate 1. The stamping box 301 has adjustment ports on both sides. Each of the two adjustment ports has multiple adjustment blocks 302 arranged in an array inside. Each of the two adjustment ports has a movable box 303 fixedly mounted on both sides of the stamping box 301. Each of the two movable boxes 303 has a movable port on the side closest to the stamping box 301. One side of each adjustment block 302 passes through the adjacent movable port and extends into the interior of the adjacent movable box 303.

[0031] The adjusting block 302 can move within the adjusting port of the stamping box 301 and the moving port of the moving box 303, changing the internal space size of the stamping box 301, thereby adapting to the production of boxes of different widths and specifications without replacing the entire lower mold assembly, thus improving the versatility of the mold.

[0032] The bottom of the inner cavity of each of the two movable boxes 303 is provided with a plurality of first fixing slots 5 arranged in an array. The top of each of the two movable boxes 303 is fixedly installed with a baffle 6. Each of the two baffles 6 is provided with a plurality of second fixing slots 7 arranged in an array and penetrating through itself. A limit plate 8 in the shape of an opening is fixedly installed on one side of each adjusting block 302. A fixing plate 9 is slidably installed inside each limit plate 8. Both ends of each fixing plate 9 extend into the interior of the adjacent first fixing slot 5 and second fixing slot 7.

[0033] The two ends of the fixing plate 9 are inserted into the first fixing groove 5 and the second fixing groove 7 respectively, which can fix the adjusting block 302 in the current position, prevent the adjusting block 302 from shifting during the stamping process, and ensure the stability of the internal space dimensions of the stamping box 301. By selecting the first fixing groove 5 and the second fixing groove 7 at different positions, the adjusting block 302 can be fixed in different positions to meet different space adjustment needs. Since the size of the battery box is specified, it is only necessary to set it according to the specified size, and it is not necessary to fix it in any position.

[0034] Multiple first sliding grooves arranged in an array are provided on both sides of the bottom of the inner cavity of the stamping box 301. Multiple second sliding grooves arranged in an array are provided on the bottom of the inner cavity of the two movable boxes 303. Each first sliding groove is connected to the adjacent second sliding groove. A first sliding block 10 is fixedly installed on the bottom side of each adjusting block 302. Each first sliding block 10 is located inside the adjacent first sliding groove.

[0035] The first sliding block 10 slides within the first and second sliding grooves, providing guidance for the movement of the adjusting block 302, ensuring the smoothness and straightness of the movement of the adjusting block 302, and preventing the adjusting block 302 from deviating during movement.

[0036] The upper mold assembly includes a lower pressure box 401 fixedly installed on the bottom side of the upper base plate 2. The top of the inner cavity of the lower pressure box 401 has multiple third sliding grooves arranged in an array. Each third sliding groove has a second sliding block 402 slidably installed at both ends. Each second sliding block 402 has a lower pressure column 403 fixedly installed on its bottom side.

[0037] The second sliding block 402 slides in the third sliding groove, which can drive the lower pressure column 403 to move and change the position of the lower pressure column 403, thereby adapting to the stamping requirements of different specifications of boxes, enabling the upper mold assembly to perform stamping processing on different positions and improving the adaptability of the upper mold assembly.

[0038] Each third sliding groove has a rotatably mounted bidirectional threaded rod 11 inside. Each second sliding block 402 is threaded onto the adjacent bidirectional threaded rod 11. Both ends of each bidirectional threaded rod 11 pass through the adjacent third sliding groove and extend to the outside of the lower pressure box 401, where a rotating block 12 is fixedly installed. A rubber ring 13 is fixedly installed on one side of each rotating block 12, and one side of each rubber ring 13 is in contact with the lower pressure box 401.

[0039] Rotating the rotating block 12 can drive the bidirectional threaded rod 11 to rotate. Since the second sliding block 402 is threaded on the bidirectional threaded rod 11, the rotation of the bidirectional threaded rod 11 can drive the two second sliding blocks 402 to move towards or away from each other along the third sliding groove, so as to achieve precise adjustment of the position of the lower pressure column 403. The rubber ring 13 is in contact with the lower pressure box 401, and the friction can limit the rotating block 12 to prevent the bidirectional threaded rod 11 from rotating during the stamping process, thus ensuring the stability of the position of the lower pressure column 403.

[0040] Each of the first sliding block 10 and the second sliding block 402 is arranged in a "T" shape, and the length and width of the pressure box 401 are both greater than the length and width of the stamping box 301.

[0041] The "T"-shaped first sliding block 10 and second sliding block 402 prevent them from disengaging from their corresponding sliding grooves, ensuring the reliability of the sliding process. The length and width of the lower pressure box 401 are greater than the length and width of the stamping box 301, ensuring that the stamping range of the upper mold assembly can cover the stamping area of ​​the lower mold assembly, and preventing excess lower pressure columns 403 from contacting the stamping box 301 and affecting normal stamping.

[0042] The implementation principle of an adaptive stamping die suitable for different specifications of boxes in this application embodiment is as follows: When it is necessary to produce boxes of different specifications, the lower die assembly is first adjusted. The operator first slides the fixing plate 9 upward, so that both ends of the fixing plate 9 disengage from the first fixing groove 5 and the second fixing groove 7, releasing the fixing of the adjusting block 302. Then, the adjusting block 302 is pushed, and the first sliding block 10 on the bottom side of the adjusting block 302 will slide in the first sliding groove of the stamping box 301 and the second sliding groove of the moving box 303, providing guidance for the movement of the adjusting block 302. The adjusting block 302 moves through the moving opening of the moving box 303 and moves in the adjusting opening of the stamping box 301, changing the internal space size of the stamping box 301 to adapt to the width specification of the box to be produced. When the adjusting block 302 moves to the target position, the fixing plate 9 is slid downward, so that both ends of the fixing plate 9 are inserted into the corresponding first fixing groove 5 and the second fixing groove 7 respectively. Through the limiting effect of the limiting plate 8 on the fixing plate 9, the adjusting block 302 is fixed in the current position, completing the adjustment of the lower die assembly.

[0043] Next, the upper mold assembly is adjusted. The operator rotates the rotating block 12, which drives the bidirectional threaded rod 11 to rotate within the third sliding groove. Since the second sliding block 402 is threaded onto the bidirectional threaded rod 11 and its sliding within the third sliding groove is restricted, the rotation of the bidirectional threaded rod 11 is converted into linear motion of the second sliding block 402, causing the two second sliding blocks 402 to move towards or away from each other along the third sliding groove. The second sliding block 402 drives the lower pressure column 403 on the bottom side to move, changing its position to match the stamping position requirements of the box to be produced. After adjustment, the rubber ring 13 and the lower pressure box 401 come into contact, generating friction to limit the rotation of the rotating block 12, preventing the bidirectional threaded rod 11 from rotating and ensuring the stability of the lower pressure column 403.

[0044] During the stamping process, the upper base plate 2 drives the upper mold assembly to move downward, and the lower pressure column 403 stamps the sheet metal placed in the stamping box 301. Since the stamping space of the lower mold assembly and the stamping position of the upper mold assembly have been adjusted according to the box specifications, the stamping of the corresponding specification box can be completed in one go.

[0045] The plastic deformation of the sheet material is mainly concentrated at the bending line of the area directly squeezed by the pressure column 403. The deformation in this area is limited to a local area through stress transfer within the material, rather than in a hollow area without the pressure column 403 in the middle. Therefore, under the restriction of multiple pressure columns 403, the central area of ​​the sheet material, that is, the area without the pressure column 403, will not produce additional deformation, so it can remain flat.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
