Abstract
Description
Technical Field
[0001] This utility model belongs to the field of busbar production, and specifically relates to a shaping tooling for busbar production. Background Technology
[0002] In the field of busbar production, traditional processes have many problems. During the multi-process flow of busbars, the dimensions are prone to change due to factors such as clamping, cutting force, and thermal stress in each process, resulting in deformation and dimensional defects.
[0003] For example, elastic deformation of the die during the extrusion process can cause "wall misalignment" in the busbar, resulting in dimensional instability; during the machining process, cutting forces and clamping forces can deform the busbar; during the heat treatment process, thermal stress caused by uneven temperature can also lead to busbar deformation, and large busbars are difficult to straighten, resulting in a low yield. These problems make the entire production process face challenges of unstable quality, high costs, and low efficiency.
[0004] Therefore, the above problems urgently need to be solved. Utility Model Content
[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a shaping fixture for busbar production. It is driven by a cylinder to press several upper pressure blocks and lower support blocks together, thereby achieving shaping. At the same time, the setting of elastic elements realizes a continuous process from positioning to pressing of the product, ensuring smooth shaping.
[0006] Technical Solution: To achieve the above objectives, this utility model provides a shaping fixture for busbar production, comprising: a base, a placement plate, a lower support assembly, and an upper pressing assembly; the placement plate is disposed on the base; the middle of the placement plate extends out of the base; several guide rods are erected on the base; a cylinder mounting plate is provided at the upper end of the guide rods; a cylinder is mounted on the cylinder mounting plate; a pressure plate is provided at the output end of the cylinder; the pressure plate is guided by the guide rods and can move up and down along the guide rods; a connecting plate is provided below the pressure plate; the lower support assembly is disposed on the placement plate and located below the pressure plate; the lower support assembly includes sequentially arranged... The upper pressing assembly comprises a first lower support block, a second lower support block, and a third lower support block on the placement plate; the upper pressing assembly is located below the pressure plate via a connecting plate and directly above the lower support assembly; the upper pressing assembly includes a first upper pressing block, a second upper pressing block, and a third upper pressing block sequentially disposed on the connecting plate; the first upper pressing block, the second upper pressing block, and the third upper pressing block are respectively located directly above the first lower support block, the second lower support block, and the third lower support block, and are pressed together in pairs to achieve shaping during pressing; the contact surface between the second upper pressing block and the second lower support block is stepped; a height difference is provided between the upper surface of the second lower support block and the upper surfaces of the first lower support block and the third lower support block.
[0007] Furthermore, the one-to-one correspondence between the upper pressure block and the lower support block ensures that the busbar receives uniform and precise pressure during the shaping process. For example, when bending or flattening the busbar, the cooperation of each pressure block and support block ensures that every part of the busbar is shaped according to the design requirements, avoiding local deformation or incomplete shaping. The contact surfaces of the second upper pressure block and the second lower support block are stepped, allowing for targeted shaping according to the shape and size of the busbar. The stepped contact surface can better adapt to the complex shape of the busbar; for example, when the busbar needs to undergo multi-stage bending or local thickening, the stepped contact surface can provide a more precise pressing effect. At the same time, this design can also reduce damage to the surface of the busbar during the shaping process, because the stepped contact surface can distribute pressure, avoiding excessive local pressure that could cause scratches or deformation on the busbar surface.
[0008] Furthermore, a number of elastic elements and a number of guide posts are provided between the second upper pressure block and the connecting plate; the second upper pressure block and the connecting plate are connected by elastic elements and guided by guide posts. Due to the buffering effect of the elastic elements, the relative movement between the second upper pressure block and the connecting plate is more stable, preventing wear caused by hard collision between the second upper pressure block and the product, effectively protecting the surface precision of the product, and avoiding scratches or deformation due to collision.
[0009] Furthermore, the placement plate is also provided with several guide blocks; the guide blocks are located on the portion of the placement plate that extends out of the base. The guide blocks ensure that the product is placed stably and that it will not wobble up and down during the shaping and pressing process, thus affecting the shaping effect.
[0010] Furthermore, a stabilizing component is provided beside the guide block; the stabilizing component includes a positioning pressure strip base, a positioning pressure strip, and a rubber pressure block; the positioning pressure strip base is located beside the guide block; the positioning pressure strip is located on the positioning pressure strip base and can rotate around the connection point, thereby lifting the end near the product; the end of the positioning pressure strip near the product is provided with a rubber pressure block. The design of the stabilizing component ensures that the product will not lift up during the shaping process, affecting the shaping effect; at the same time, the design of the rubber pressure block also ensures that it will not damage the upper surface of the product.
[0011] Furthermore, the end of the placement plate extending beyond the base, away from the base, is also provided with several positioning slots. These positioning slots provide precise placement grooves for the product's end face design, thereby improving the overall positioning effect of the product.
[0012] Furthermore, the placement plate is also provided with height limiting blocks; the height limiting blocks are located on both sides of the first and third lower support blocks. The height limiting blocks provide height limitation for downward pressure, preventing overpressure damage to the product.
[0013] Furthermore, both the first upper pressure block and the third lower support block are provided with clearance grooves. The clearance grooves are designed to provide space for the electrical components on the product and prevent damage to the product itself.
[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0015] 1. This utility model discloses a shaping fixture for busbar production, which is driven by a cylinder to press several upper pressure blocks and lower support blocks together, thereby achieving shaping; at the same time, the setting of elastic elements realizes a continuous process from positioning to pressing of the product, ensuring smooth shaping.

[0039] Specifically, each positioning slot 23 corresponds to a shaping station, greatly increasing the versatility of the tooling.

[0044] The working principle of the above embodiments is as follows:
[0045] This utility model discloses a shaping fixture for busbar production. In use, the product is placed on guide block 21, first lower block 31, second lower block 32, and third lower block 33.
