Description

Technical Field

[0001] This utility model belongs to the field of battery connector stamping technology, and in particular relates to a stamping mold for anti-displacement battery connectors. Background Technology

[0002] With the rapid development of new energy vehicles, portable electronic devices, and energy storage systems, batteries, as the core power source, have a decisive impact on the overall performance of the device due to their internal structural design and manufacturing quality. Battery connectors, as key components for conducting current between battery cells, not only need excellent conductivity but also meet extremely high requirements in terms of size, flatness, and positional accuracy. Therefore, during their production, the stamping quality of the connectors directly affects the performance stability and lifespan of the entire battery pack. To improve the processing efficiency and consistency of connectors, die stamping technology is widely used in mass automated production.

[0003] Existing battery connector stamping dies typically include an upper die, lower die, guide pillars and bushings, a stripper plate, and a punch. During the stamping process, downward pressure is applied by the press, and the upper die drives the punch to cut and shape the connector material. Most dies adopt a progressive die structure, which can realize multi-station integrated processing such as punching, shearing, and bending, and has a high production cycle and automation capability. This type of die has a mature structure, strong versatility, and performs well in standardized production scenarios.

[0004] Although existing stamping dies can efficiently process connecting pieces, there is still a certain probability of raw material misalignment during actual production. Especially in high-speed continuous stamping operations, minor errors in material placement, equipment vibration, or die wear can easily lead to deviations in the stamping position of the connecting pieces, resulting in quality problems such as incorrect finished product dimensions, misaligned holes, or deformation. This not only reduces the yield rate but may also cause subsequent problems such as structural misalignment and poor contact during battery assembly. Therefore, how to effectively avoid connecting piece misalignment during stamping and improve die stability and stamping accuracy is one of the important issues that needs to be addressed in current die design and optimization. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping die for anti-offset battery connectors, which aims to solve the technical problem in the prior art that the connectors are prone to deviation in the stamping position due to factors such as slight errors in material placement, equipment vibration or die wear during high-speed continuous stamping operations.

[0006] To achieve the above objectives, the present invention provides an anti-offset battery connector stamping die including a base, a connecting frame fixedly connected to the outer wall of the base, a roller provided inside the connecting frame, and a limit component provided on the upper surface of the base; The limiting component includes a limiting plate, a sliding block fixedly connected to the outer wall of the limiting plate, a connecting block one slidably connected to the outer wall of the sliding block, a connecting rod inside the connecting block one, a spring sleeved on the outer wall of the connecting rod, a connecting block two fixedly connected to the outer wall of the sliding block, a limiting block slidably connected to one end of the connecting block two, a limiting groove inside the limiting block, the connecting block two being disposed inside the limiting groove, and a connecting plate one fixedly connected to the upper surface of the limiting block.

[0007] Optionally, a limiting rod is fixedly connected to the lower surface of the connecting plate, and a second connecting plate is fixedly connected to one end of the limiting rod. A quick-release block is provided inside the second connecting plate. Limiting rings one and two are slidably connected to both sides of the outer wall of the quick-release block. A lead screw is rotatably connected inside the first limiting ring, and a lead screw is threaded inside the second limiting ring. A clamp is fixedly connected to the outer wall of the second limiting ring, and a quick-release plate is fixedly connected to the outer wall of the clamp.

[0008] Optionally, an upper mold is fixedly connected to the lower surface of the quick-release plate, and a lower mold is provided below the upper mold.

[0009] Optionally, a housing is fixedly connected to one upper surface of the connecting plate, and a hydraulic cylinder is installed inside the housing.

[0010] Optionally, the output end of the hydraulic cylinder is fixedly connected to the upper surface of the second connecting plate, and the output end of the hydraulic cylinder is disposed inside the first connecting plate.

[0011] Optionally, a lower mold is fixedly connected to the upper surface of the base, and a hydraulic rod is fixedly connected to the upper surface of the base.

[0012] Optionally, a first connecting plate is fixedly connected to the upper surface of the hydraulic rod, and a hydraulic cylinder is fixedly connected to the upper surface of the first connecting plate.

[0013] Optionally, one end of the connecting rod is fixedly connected to the outer wall of the limiting plate, and the connecting rod is located below the sliding block.

[0014] The above-mentioned technical solutions in the anti-offset battery connector stamping die provided in this embodiment of the utility model have at least one of the following technical effects: 1. In this utility model, a hydraulic cylinder drives the second connecting plate to move up and down. The lower surface of the second connecting plate is connected to a quick-release plate and an upper mold. The up and down movement of the second connecting plate drives the quick-release plate and the upper mold to move up and down. The material enters the upper mold through the rollers and is stamped by the upper mold. During the material conveying process, deviations may occur. At this time, the limiting block will move downward together with the first connecting plate, so that the second connecting plate slides upward inside the limiting groove, driving the sliding block to move horizontally inside the first connecting plate, pushing the limiting plate to clamp the material and limit it to effectively avoid the deviation of the connecting plate during the stamping process, thereby improving the stability of the mold and the stamping accuracy.

[0015] 2. In this utility model, rotating the first limiting ring causes the second limiting ring and the first limiting ring to move outwards, allowing them to move horizontally outwards from the lead screw. This causes the two limiting rings to slide out of the quick-release block, enabling the quick-release block to be quickly pulled out of the fixture. The fixture is located on the outer wall of the quick-release plate, while the quick-release block is inside the second connecting plate. This allows for the quick removal and replacement of the lower mold, improving production efficiency and facilitating mold maintenance and management. Attached Figure Description

[0023] In one embodiment of this utility model, such as Figures 1-4A stamping die for anti-offset battery connector is provided, including a base 1. The base 1 is mainly used to support the workbench and plays a fixed support role. A connecting frame 2 is fixedly connected to the outer wall of the base 1.

A limit component is provided on the upper surface of the base 1. The limiting assembly includes a limiting plate 17, with a sliding block 6 fixedly connected to its outer wall. The sliding block 6 slides inside connecting block 1 5, compressing the limiting plate 17. Connecting block 1 5 is slidably connected to the outer wall of the sliding block 6. Connecting rod 19 is provided inside connecting block 15, and spring 20 is sleeved on the outer wall of connecting rod 19.

One end of connecting block 2 15 is slidably connected to the limiting block 7. The limiting block 7 has a limiting groove 16 inside, and connecting block 2 15 is located inside the limiting groove 16. Connecting plate 1 8 is fixedly connected to the upper surface of the limiting block 7. In another embodiment of this utility model, such as Figures 1-4 A limiting rod 10 is fixedly connected to the lower surface of connecting plate 11. The limiting rod 10 mainly prevents the hydraulic cylinder 14 from misaligning when pressing connecting plate 21. One end of the limiting rod 10 is fixedly connected to connecting plate 21. A quick-release block 21 is provided inside connecting plate 21. Limiting rings 1 and 25 are slidably connected to both sides of the outer wall of quick-release block 21. Limiting ring 25 has a threaded structure inside, while limiting ring 1 has a smooth structure inside, which serves to fix the annular structure at the bottom of quick-release block 21. A lead screw 23 is rotatably connected inside limiting ring 12, and a lead screw 23 is threaded inside limiting ring 25. A clamp 22 is fixedly connected to the outer wall of limiting ring 25, and a quick-release plate 12 is fixedly connected to the outer wall of clamp 22. The quick-release plate 12 is mainly used to fix the upper mold 13, which plays a fixing role. The upper mold 13 is fixedly connected to the lower surface of quick-release plate 12. The battery connecting pieces are all the same shape and have grooves inside for easy cutting. A lower mold 18 is set below the upper mold 13. A housing 9 is fixedly connected to the upper surface of the connecting plate 11. A hydraulic cylinder 14 is set inside the housing 9. The hydraulic cylinder 14 is mainly used to provide power so that the connecting plate 11 moves vertically, driving the upper mold 13 to move vertically to squeeze the battery connecting pieces. The output end of the hydraulic cylinder 14 is fixedly connected to the upper surface of the connecting plate 11. The output end of the hydraulic cylinder 14 is set inside the connecting plate 11. A lower mold 18 is fixedly connected to the upper surface of the base 1. The lower mold 18 has a metal groove structure design and is the same shape as the battery connecting pieces. A hydraulic rod 4 is fixedly connected to the upper surface of the base 1. The connecting plate 11 is fixedly connected to the upper surface of the hydraulic rod 4. The hydraulic cylinder 14 is fixedly connected to the upper surface of the connecting plate 11. One end of the connecting rod 19 is fixedly connected to the outer wall of the limiting plate 17. The connecting rod 19 is set below the sliding block 6.

[0024] Working principle: When using the battery connector stamping die, the hydraulic cylinder 14 drives the connecting plate 11 to move up and down vertically. The lower surface of the connecting plate 11 is connected to the quick-release plate 12 and the upper die 13. During the movement, the upper die 13 forms a stamping fit with the lower die 18 to complete the precision processing of the material. The raw material is conveyed by the roller 3 to the top of the lower die 18. As the upper die 13 descends, it applies an instantaneous impact force to the material for stamping. However, during the conveying process, the material may shift position due to uneven speed or track error, thus affecting the stamping. To ensure precision, the device is equipped with a limiting block 7, which moves vertically in coordination with the connecting plate 8, thereby causing the connecting block 15 to slide upward in the limiting groove 16. The movement of the connecting block 15 causes the sliding block 6 to slide horizontally along the internal slide of the connecting block 5, thereby pushing the limiting plate 17 to clamp the edge of the material and achieve secondary stabilization and fixation of the material position. This design can effectively eliminate stamping errors caused by material offset, improve the stability of the mold and the dimensional accuracy of the finished product during the stamping process, and is particularly suitable for battery connecting piece stamping scenarios with high precision requirements. Furthermore, to facilitate mold switching for connecting pieces of different specifications, the system adopts a quick-release structure design. When mold replacement is required, firstly, the limiting ring 24 is manually rotated, causing it and the limiting ring 25 to move outward synchronously. The two limiting rings are connected to the lead screw 23 via threads. After the limiting rings 24 and 25 move to a specific position, they can be horizontally removed from the lead screw 23. As the limiting rings are removed, the structure originally locked to the quick-release block 21 is released, and the quick-release block 21 can be pulled out of the clamp 22. The quick-release plate 12 is set on the outer wall of the quick-release plate 12. The quick-release block 21 is securely installed inside the connecting plate 11 through the matching structure. The upper mold 13 is then connected to the quick-release plate 12 through the quick-release block 21. Thus, the entire disassembly and replacement process of the upper mold 13 can be quickly completed after the quick-release block 21 is removed. This structure significantly simplifies the mold replacement steps, saves a lot of manual operation time in traditional disassembly and assembly, reduces the risk of misoperation, and improves the overall mold system operation and maintenance efficiency. It is especially suitable for battery manufacturing production lines where molds are frequently changed.
