Description

Technical Field

[0001] This utility model relates to the field of copper busbar processing technology, specifically to an extrusion die for copper busbar production. Background Technology

[0002] Copper busbars are widely used in the power industry due to their excellent conductivity and mechanical strength, especially in high-voltage electrical appliances, generators, and transformers as the main components for current transmission. Copper busbars are mostly produced using extrusion dies. The forming grooves of the extrusion die have specific shapes and dimensions, and the copper material is extruded into copper busbars of the required dimensions under the action of the die. Different sizes of copper busbars can be produced using different extrusion dies.

[0003] However, the surface of copper busbar materials sometimes carries impurities such as oxides and oil stains. During the extrusion process, these impurities may be compressed into small particles, forming debris. Furthermore, after prolonged use, the surface of the die may become rough due to friction and wear, leading to the generation of debris during the extrusion process as well. These debris can affect the quality of the copper busbar. To address these issues, we propose an extrusion die for copper busbar production. Utility Model Content

[0004] The purpose of this invention is to provide an extrusion die for the production of copper busbars, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion die for copper busbar production, comprising a frame, wherein multiple sets of die extrusion assemblies are arranged within the frame, and a cleaning ring seat is provided on one side of the inlet of each set of die extrusion assemblies. Multiple cleaning components are provided within the cleaning ring seat, and a cleaning space for copper busbars to pass through is formed between the cleaning ends of the multiple cleaning components. A rotating component for driving the cleaning components to rotate is also provided within the cleaning ring seat, and an adjusting component for adjusting the size of the cleaning space is also provided on the cleaning ring seat.

[0006] According to the above technical solution, a mounting ring is fixedly connected inside the rotating component, and the cleaning component array is arranged on the outer wall of the mounting ring. An annular groove for inserting an adjusting component is formed between the mounting ring and the rotating component. The adjusting component includes an abutment ring that slides in the annular groove. One end of the cleaning component penetrates the outer wall of the mounting ring and has an inclined surface facing the abutment ring.

[0007] According to the above technical solution, the adjusting component includes a rotating ring that is threadedly connected to the inner wall of the cleaning ring seat, and one end of the rotating ring extends into the annular groove and is connected to the abutment ring.

[0008] According to the above technical solution, the cleaning component includes a movable rod that passes through the mounting ring, and a busbar cleaning brush is provided at one end of the movable rod near the center of the cleaning ring seat. An elastic element connected to the mounting ring is provided on the movable rod.

[0009] According to the above technical solution, the bottom of the cleaning ring seat is fixedly connected to the mounting housing connected to the frame, the mounting housing is rotatably provided with a first gear, and the outer wall of the mounting ring is provided with teeth in the circumferential direction. The first gear meshes with the mounting ring through the teeth.

[0010] According to the above technical solution, the die extrusion assembly includes a base fixed to the frame, two die pressure rollers are rotatably provided on the top of the base, and a second gear is provided inside the base, which is respectively connected to the two die pressure rollers and the two second gears mesh with each other.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention features a cleaning ring seat on one side of the die extrusion assembly inlet, containing multiple cleaning components and rotating parts. This allows for comprehensive cleaning of the copper busbar's surface before it enters the die extrusion assembly, effectively removing impurities and debris. Simultaneously, a pressure roller cleaning brush is provided at the die pressure roller to ensure the cleanliness of the die pressure roller. The combined effect of these two features significantly improves the production quality of the copper busbar.

[0016] This invention features an adjustable element on the cleaning ring seat, allowing for adjustment of the cleaning space size to accommodate copper busbars of different diameters. When processing copper busbars of varying sizes, the operator rotates the rotating ring. Since the rotating ring is threaded to the inner wall of the cleaning ring seat, it moves axially along the inner wall during rotation. This axial movement of the rotating ring causes the abutment ring to slide within an annular groove, which, in turn, engages with an inclined surface, causing the moving rod to move the busbar cleaning brush, thus altering the size of the cleaning space.

[0026] 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.

[0027] Please see Figure 1-7This utility model provides a technical solution for an extrusion die for copper busbar production: it includes a frame 1, within which multiple sets of die extrusion assemblies 2 are arranged to extrude copper material into finished copper busbars conforming to specifications. Each set of die extrusion assemblies 2 has a cleaning ring seat 3 on one side of its inlet. The cleaning ring seat 3 has a clearance hole for the copper busbar to pass through. Multiple cleaning components 4 are provided inside the cleaning ring seat 3, and a cleaning space for the copper busbar to pass through is formed between the cleaning ends of the multiple cleaning components 4. The inlet / outlet of the die extrusion assembly 2, the clearance hole, and the cleaning space are arranged in a straight line. When the copper busbar passes through the cleaning space, it can be cleaned by the surrounding cleaning components 4.

[0028] The cleaning ring seat 3 is also equipped with a rotating part 5 for driving the cleaning component 4 to rotate. The rotating part 5 can drive the cleaning component 4 to rotate continuously to clean the copper busbar and ensure that the copper busbar is cleaned in an all-round and efficient manner.

[0029] The cleaning ring seat 3 is also provided with an adjustment component 6 for adjusting the size of the cleaning space. The size of the cleaning space can be adjusted by adjusting the cleaning component 4 through the adjustment component 6 to accommodate copper busbars of different diameters.

[0030] By setting a cleaning ring seat 3 on the inlet side of the die extrusion assembly 2, and arranging multiple cleaning components 4 and rotating parts 5 inside the cleaning ring seat 3, the surface of the copper busbar can be thoroughly cleaned before entering the die extrusion assembly 2, effectively removing impurities and any debris that may be generated, thereby significantly improving the production quality of the copper busbar. Simultaneously, the adjustment component 6 allows the cleaning ring seat 3 to adapt to the production needs of copper busbars of different specifications, further enhancing the practicality and versatility of the extrusion die.

[0031] Specifically, a mounting ring 7 is fixedly connected inside the rotating part 5, and multiple cleaning components 4 are arranged in an array on the outer wall of the mounting ring 7 to ensure that the cleaning components 4 in all directions can effectively clean the copper busbar when it passes through the cleaning space.

[0032] An annular groove is formed between the mounting ring 7 and the rotating component 5 for the insertion of the adjusting component 6. The adjusting component 6 includes an abutment ring 61 that slides within the annular groove. One end of the cleaning component 4 penetrates the outer wall of the mounting ring 7 and has an inclined surface facing the abutment ring 61. When the adjusting component 6 moves deeper into the annular groove, the abutment ring 61, during its sliding process, can push the cleaning component 4 to move by contacting the inclined surface, causing the cleaning end of the cleaning component 4 to move closer to the center (towards the copper busbar), thereby adjusting the size of the cleaning space. This adjustment method has a simple structure and is easy to operate, enabling rapid and accurate adjustment according to copper busbars of different diameters, further improving the adaptability and practicality of the device.

[0033] Specifically, the adjusting component 6 includes a rotating ring 62 threadedly connected to the inner wall of the cleaning ring seat 3. One end of the rotating ring 62 extends into the annular groove and connects to the abutment ring 61. When processing copper busbars of different sizes, the operator can rotate the rotating ring 62 to adjust the size of the cleaning space. Since the rotating ring 62 is threadedly connected to the inner wall of the cleaning ring seat 3, it moves axially along the inner wall of the cleaning ring seat 3 during rotation. As the rotating ring 62 moves axially, it drives the abutment ring 61 to slide within the annular groove. When the abutment ring 61 moves deeper into the annular groove, as mentioned earlier, it contacts the inclined surface of one end of the cleaning component 4, pushing the cleaning component 4 to move, causing the cleaning end of the cleaning component 4 to move towards the center (towards the copper busbar), thereby reducing the size of the cleaning space. This adjustment method using the rotating ring 62 is not only simple in structure and convenient in operation, but also allows for quick and accurate adjustment according to copper busbars of different diameters, further improving the adaptability and practicality of the device.

[0034] Specifically, the cleaning component 4 includes a movable rod 41 that passes through the mounting ring 7. A busbar cleaning brush 42 is provided at one end of the movable rod 41 near the center of the cleaning ring seat 3. The busbar cleaning brush 42 can directly contact the copper busbar. When the rotating component 5 drives the cleaning component 4 to rotate, the busbar cleaning brush 42 effectively cleans the impurities and debris on the surface of the copper busbar.

[0035] The movable rod 41 is equipped with an elastic element 43 connected to the mounting ring 7. The elastic element 43 can be a tension spring. When the abutment ring 61 of the adjusting member 6 pushes the movable rod 41 to adjust the size of the cleaning space, the elastic element 43 will be compressed or stretched. When it is necessary to increase the size of the cleaning space, the elastic element 43 can provide a certain restoring force. When the abutment ring 61 moves to the shallow part of the annular groove, the movable rod 41 loses the obstruction of the abutment ring 61. Under the elastic action of the elastic element 43, the movable rod 41 will cause the busbar cleaning brush 42 to move away from the center, thereby increasing the size of the cleaning space.

[0036] Specifically, the bottom of the cleaning ring seat 3 is fixedly connected to a mounting housing 8, which is connected to the frame 1. The mounting housing 8 serves to fix and support the device. A first gear 9 is rotatably mounted inside the mounting housing 8, and teeth 10 are circumferentially provided on the outer wall of the mounting ring 7. The first gear 9 meshes with the mounting ring 7 through the teeth 10. When the first gear 9 rotates, it drives the mounting ring 7 to rotate through the meshing action with the teeth 10 on the outer wall of the mounting ring 7. The rotation of the mounting ring 7, in turn, drives the cleaning assembly 4 on it to rotate, enabling the busbar cleaning brush 42 to perform comprehensive cleaning of the copper busbar.

[0037] Specifically, the die extrusion assembly 2 includes a base 21 fixedly connected to the frame 1, which provides stable support and a mounting foundation for the die extrusion assembly 2. Two die pressure rollers 22 are rotatably mounted on the top of the base 21. The two die pressure rollers 22 cooperate with each other to perform extrusion and forming operations on the passing copper busbar.

[0038] The base 21 contains second gears 23 connected to two die rollers 22, and the two second gears 23 mesh with each other. The bottom of the base 21 also has a drive component 24 connected to one of the second gears 23. When one of the second gears 23 is driven to rotate by the drive component 24, the other second gear 23 will also rotate due to the meshing action, thus achieving synchronous and counter-rotating of the two die rollers 22. The drive component 24 can be a motor or other power device to provide power for the rotation of the die rollers 22. This design, through gear meshing and the cooperation of the drive component 24, ensures stable and synchronous rotation of the two die rollers 22, enabling efficient and accurate extrusion processing of the copper busbar, thus improving the quality and efficiency of copper busbar processing.

[0039] Specifically, the top of the base 21 is also rotatably provided with a roller cleaning brush 11 that abuts against the mold roller 22, and the bottom of the roller cleaning brush 11 is connected to the third gear 12 via a shaft.

[0040] The pressure roller cleaning brush 11 can clean the surface of the mold pressure roller 22 during its operation, removing impurities and residues that may adhere to the mold pressure roller 22, ensuring the cleanliness of the mold pressure roller 22, thereby improving the quality of copper busbar extrusion molding.

[0041] When the drive component 24 drives the second gear 23 to rotate, it drives the fourth gear 16 to rotate, which in turn drives the third gear 12 to rotate, ultimately causing the pressure roller cleaning brush to rotate. During the operation of the die pressure roller 22, the pressure roller cleaning brush can continuously clean its surface, effectively removing various impurities and residues attached to the die pressure roller, ensuring that the die pressure roller is always in a clean state, thereby greatly improving the quality and stability of copper busbar extrusion molding.

[0042] Specifically, the die extrusion assembly 2 includes a drive member 24, which is connected to the first gear 9 via a gear set 13. The drive member 24 can also provide rotational power to the first gear 9 via the gear set 13.

[0043] Specifically, a guide platform 14 is fixed to the outer wall of the frame 1, and a guide wheel 15 is provided on the guide platform. The guide wheel 15 can guide the transport of the copper busbar, thereby improving the stability and accuracy of the copper busbar during the processing.
