Description

Technical Field

[0001] This utility model relates to the field of hard copper bar stamping technology, specifically a new energy double-flow-surface hard copper bar stamping edge-cutting structure. Background Technology

[0002] The new energy dual-flow-surface hard copper bar is a type of copper hard connector commonly used in new energy batteries. It is used for transition and connection between modules. The transition and connection area is the functional surface, which is divided into the locking surface and the flow-surface. During the processing, the waste material at the edge needs to be stamped and trimmed.

[0003] In existing stamping structures, the U-shaped punch directly cuts the hard copper bar during stamping, and the scrap material falls through the cutting edge, the lower backing plate, and the lower die base. During the stamping process, the cutting edge mainly bears the cutting force. However, because the lower backing plate and the lower die base are designed with scrap material to create space, the strength of the cutting edge is further weakened, affecting the cutting edge life. This makes it impossible to mass produce effectively, and the cutting edge is damaged quickly, requiring frequent replacement of the cutting edge, resulting in high manufacturing costs. Therefore, this utility model proposes a new energy double-flow-surface hard copper bar stamping and cutting structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a new energy double-flow-surface hard copper bar stamping and trimming structure, which solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a new energy double-flow-surface hard copper stamping and trimming structure, including a U-shaped punch, and further comprising:

[0006] The lower template is located at the bottom of the U-shaped punch, and a groove is provided in the middle of the lower template;

[0007] A hard copper bar, which is located at the upper end of the lower template and has a separation waste material connected to its outer side;

[0008] A side-conical blade assembly, wherein the side-conical blade assembly is located inside the groove;

[0009] A side-conical cutting edge, which is located inside the groove and abuts against the side-conical cutting edge assembly.

[0010] Furthermore, a new energy dual-flow-surface hard copper bar stamping and trimming structure also includes:

[0011] The lower pad is located at the bottom of the lower template and a disassembly assembly is provided between the lower template and the lower template.

[0012] The lower mold base is located at the bottom of the lower pad.

[0013] Furthermore, the disassembly assembly includes a moving groove in the middle of the lower pad, a positioning groove inside the lower template, a push plate inside the moving groove, a positioning block connected to the upper end of the push plate, a hand-held block connected to one end of the push plate, and a support spring connected to one side of the positioning block.

[0014] Furthermore, the number of the moving slots is two sets and symmetrically distributed, the number of the positioning slots is equal to the number of the moving slots, and the moving slots and the positioning slots are connected to each other.

[0015] Furthermore, the push plate is adapted to the moving groove, the push plate is fixedly connected to the positioning block, the side profile of the positioning block is an "L" shaped structure, the positioning block is adapted to the positioning groove, the hand-held block is fixedly connected to the push plate, and the hand-held block is made of rubber.

[0016] Furthermore, the number of support springs is twice the number of positioning blocks, and the two ends of the support springs are connected to the positioning blocks and the moving groove, respectively.

[0017] Furthermore, both the lower pad and the lower mold base have waste material drop holes of the same diameter in the middle.

[0018] Compared to the aforementioned background technology, the new energy double-flow-surface hard copper bar stamping and cutting structure provided in this application includes a lower die, a groove, a side conical blade assembly, and a side conical blade. In order to address the issue of enhancing the strength of the lower die blade edge during stamping and separating waste, a split structure is designed through the side conical blade and the side conical blade assembly. The side conical blade is designed with a reverse blade to separate the waste and allow it to fall smoothly, thus ensuring the strength of the lower die blade edge.

At this time, the positioning block releases the restraint on the positioning groove, thereby moving the lower template upward, and then disassembling between the lower template and the lower pad. In subsequent maintenance and repair, it saves time and effort. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Please see Figure 1-6 This utility model provides a technical solution for a new energy double-flow-surface hard copper bar stamping and cutting structure: a new energy double-flow-surface hard copper bar stamping and cutting structure, including a U-shaped punch 1, and further including: a lower template 2, the lower template 2 is located at the bottom of the U-shaped punch 1, and a groove is opened in the middle of the lower template 2; a hard copper bar 3, the hard copper bar 3 is located at the upper end of the lower template 2, and the outer side of the hard copper bar 3 is connected to the separation waste material 6; a side conical blade assembly 4, the side conical blade assembly 4 is located inside the groove; a side conical blade 5, the side conical blade 5 is located inside the groove and abuts against the side conical blade assembly 4, thereby facilitating the combination of the side conical blade assembly 4 and the side conical blade 5, and facilitating the punching and cutting of the separation waste material 6.

[0032] The lower pad 7 is located at the bottom of the lower template 2, and a disassembly assembly 9 is provided between the lower template 2 and the lower mold base 8. The lower mold base 8 is located at the bottom of the lower pad 7. Both the lower pad 7 and the lower mold base 8 have waste material dropping holes with the same diameter in the middle, which facilitates the dropping of the separated waste material 6.

[0033] In addition, the disassembly assembly 9 includes a moving groove 91 in the middle of the lower pad 7, a positioning groove 92 inside the lower template 2, a push plate 93 inside the moving groove 91, a positioning block 94 connected to the upper end of the push plate 93, a hand-held block 95 connected to one end of the push plate 93, and a support spring 96 connected to one side of the positioning block 94. There are two sets of moving grooves 91, which are symmetrically distributed. The number of positioning grooves 92 is equal to the number of moving grooves 91. The moving grooves 91 and the positioning grooves 92 are connected. The push plate 93 is adapted to the moving grooves 91. The push plate 93 is fixedly connected to the positioning block 94. The side profile of the positioning block 94 is an "L" shaped structure. The positioning block 94 is adapted to the positioning groove 92. The hand-held block 95 is fixedly connected to the push plate 93. The hand-held block 95 is made of rubber. The number of support springs 96 is twice the number of positioning blocks 94. The two ends of the support springs 96 are connected to the positioning block 94 and the moving groove 91, respectively, which facilitates the disassembly of the lower template 2 and the lower pad 7.

[0034] This new energy double-flow-surface hard copper bar stamping and cutting structure, during the stamping and cutting process, combines the side conical blade assembly 4 and the side conical blade 5 in the groove, and then installs them in the middle of the lower template 2. After installation, the tip of the side conical blade 5 is located in the middle of the separated waste material 6, forming an upward reverse punching cut. After the U-shaped punch 1 punches the product, it enters the side conical blade assembly 4 and the side conical blade 5. During the downward process, the side conical blade 5 punches the separated waste material 6 in the reverse direction. The stroke is calculated, and 0.1MM of material thickness is left uncut. When the U-shaped punch 1 punches for the second time, it pushes the separated waste material 6 again, and at the same time pushes the separated waste material 6 from the first time to the side conical blade 5, cutting the separated waste material 6 in the reverse direction. The material slides to both sides and passes through the waste material drop hole in the middle of the lower pad 7 and the lower die base 8, realizing U-shaped single-sided punching.

[0035] It should be noted that the side conical blade 5 and the side conical blade assembly 4 are designed with a split structure and a reverse blade to separate the waste material 6, allowing it to fall smoothly and ensuring the attachment... Figure 7 The strength of the lower die cutting edge (D) is improved; at the same time, the lower pad 7 does not need to be completely cleared, and a connection position is designed under the side conical cutting edge 5 to ensure strength; the lower die base 8 does not need to be completely cleared, and a connection position is designed in the same position to ensure strength; the side conical cutting edge 5 and the side conical cutting edge combination 4 can effectively solve the problems of insufficient strength of the lower die cutting edge, inability to effectively mass produce, low production efficiency, rapid cutting edge damage, and high manufacturing cost in the new energy double flow surface hard copper bar U-shaped stamping and cutting technology.

[0036] It should be noted that, by setting up the disassembly component 9, when disassembling between the lower template 2 and the lower pad 7, pressing the hand blocks 95 on both sides causes the hand blocks 95 to drive the push plate 93 to move along the inside of the moving groove 91, while simultaneously driving the positioning block 94 to move along the inside of the positioning groove 92 and compressing the support spring 96 until the hand blocks 95 contact the outer surface of the lower pad 7. At this point, the positioning block 94 is released from its restraint on the positioning groove 92, thereby allowing the lower template 2 to be moved upward, and thus disassembling between the lower template 2 and the lower pad 7. This saves time and effort in subsequent maintenance and repair.
