Technical Field
[0001] This application relates to the field of copper plate drawing technology, and in particular to a copper busbar precision drawing device. Background Technology
[0002] In the electrical industry, copper busbars are a key conductive material widely used in the manufacture of power equipment such as high and low voltage electrical appliances, switch cabinets, and distribution boxes. As the core equipment for producing high-precision copper busbars, the performance of the copper busbar precision drawing device directly affects the quality and production efficiency of the copper busbars.
[0003] Some existing copper busbar precision drawing devices cannot properly position and center the copper busbar during the feeding and drawing process, causing the copper busbar to deviate or tilt during the feeding and drawing process, thereby reducing the stability of the drawing process. In addition, existing copper busbar precision drawing devices cannot properly straighten the copper busbar before drawing, making it difficult to achieve the high-precision straightness requirements after drawing. Utility Model Content
[0004] To address the problems mentioned in the background art, this application provides a copper busbar fine drawing device.
[0005] The copper busbar fine drawing device provided in this application adopts the following technical solution:
[0006] A copper busbar fine drawing device includes a worktable, a positioning mechanism at the middle position of the top of the worktable, a drawing mechanism fixedly installed at the left edge of the top of the worktable, two symmetrical support plates at the right edge of the top of the worktable, a plurality of conveying rollers rotatably installed between the two support plates, and a straightening component for straightening the copper busbar at the top of the support plates.
[0007] Preferably, the positioning mechanism includes a support seat installed at the middle position on the top of the workbench, and the top of the support seat is provided with a sliding groove, in which two symmetrical sliding seats are slidably installed.
[0008] Preferably, a connecting frame is connected to one side of each of the two sliding seats, and a positioning roller is rotatably installed inside the connecting frame. A connecting block is also provided at the bottom of the sliding seat, and one end of the connecting block passes through a symmetrical through groove provided at the bottom of the sliding groove.
[0009] Preferably, the bottom of the support base is provided with two symmetrical mounting seats at both sides. Symmetrical L-shaped rack plates are slidably installed inside the two mounting seats. One end of each L-shaped rack plate is connected to one side of the connecting block. Gears mesh between the L-shaped rack plates. The gears are rotatably mounted on a fixed rod provided at the bottom of the support base.
[0010] Preferably, a cylinder is also fixedly installed on one side wall of the support base. The output end of the cylinder passes through a through hole opened in the side wall of the support base and is connected to a connecting block provided at the bottom of one of the sliding seats.
[0011] Preferably, the straightening assembly includes three support frames installed on the top of two support plates. Symmetrical openings are provided on the side walls at both ends of the three support frames. Slide rods are provided inside the openings. Threaded rods are installed in threaded holes opened on the top of the support frames. One end of each threaded rod is connected to a fixing frame. Slider blocks provided at both ends of the fixing frames are adapted to the slide rods.
[0012] Preferably, a primary straightening roller is rotatably mounted on the bottom of the first fixed frame, a secondary straightening roller is rotatably mounted on the bottom of the second fixed frame, and a fine straightening roller is rotatably mounted on the bottom of the third fixed frame.
[0013] In summary, this application includes the following beneficial technical effects:
[0014] 1. This utility model is equipped with a novel positioning mechanism. By driving the cylinder to push the connecting block at the bottom of one of the sliding seats, the L-shaped rack plate connected on one side slides along the mounting seat and drives the gear to rotate, thereby driving the other L-shaped rack plate to slide along the mounting seat. This causes the two sliding seats to slide towards each other along the sliding groove, driving the positioning roller to move towards each other and contact the surface of the copper busbar. This allows the copper busbar to be automatically positioned on the drawing center line. At the same time, it can effectively prevent the copper busbar from shifting or tilting during the feeding process, ensuring the stability of the drawing process.
[0015] 2. This utility model is equipped with a straightening component. Before the copper busbar is conveyed to the drawing mechanism, the threaded rod is rotated to drive the fixed frame to slide down along the slide bar, so that the copper busbar passes through the primary straightening roller. The primary straightening roller performs preliminary straightening on the copper busbar to eliminate large bending and deformation. Then the copper busbar passes through the secondary straightening roller to further improve the straightening accuracy. Finally, the copper busbar is finally finely straightened by the fine straightening roller to ensure that the copper busbar meets the high-precision straightness requirements.

[0021] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.
[0022] This application discloses a copper busbar fine drawing device, including a workbench 1. A positioning mechanism is provided at the middle position of the top of the workbench 1. A drawing mechanism 2 is fixedly installed at the left edge of the top of the workbench 1. Two symmetrical support plates 3 are provided at the right edge of the top of the workbench 1. A plurality of conveying rollers 4 are rotatably installed between the two support plates 3. A straightening component for straightening the copper busbar is also provided on the top of the support plates 3.
[0023] refer to Figure 2 and Figure 3The positioning mechanism includes a support base 5 installed at the center of the top of the workbench 1. A sliding groove 6 is provided on the top of the support base 5, and two symmetrical sliding seats 7 are slidably installed within the sliding groove 6. A connecting frame 8 is connected to one side of each sliding seat 7, and a positioning roller 9 is rotatably installed inside the connecting frame 8. A connecting block 10 is also provided at the bottom of each sliding seat 7, with one end of the connecting block 10 passing through a symmetrical through groove at the bottom of the sliding groove 6. Two symmetrical mounting seats 11 are also provided at the bottom edges of the support base 5, and symmetrical L-shaped rack plates 12 are slidably installed inside each mounting seat 11. One end of each L-shaped rack plate 12 is connected to one side of the connecting block 10, and gears 13 mesh between the L-shaped rack plates 12. The gears 13 are rotatably installed on a fixed rod at the bottom of the support base 5. A pneumatic rod is also fixedly installed on one side wall of the support base 5. The output end of cylinder 14 passes through a through hole in the side wall of support base 5 and is connected to a connecting block 10 at the bottom of one of the sliding seats 7. More specifically, by driving cylinder 14, the connecting block 10 at the bottom of one of the sliding seats 7 is pushed to slide along the through groove, causing the L-shaped rack plate 12 connected on one side to slide along the mounting base 11 and drive the gear 13 to rotate, thereby causing the L-shaped rack plate 12 connected on one side of the other connecting block 10 to slide along the mounting base 11, thereby causing the sliding seats 7 connected at one end of the two connecting blocks 10 to slide towards each other along the sliding groove 6 at the top of support base 5, so that the positioning roller 9 installed in the connecting frame 8 connected on one side of the sliding seat 7 moves towards each other and contacts the surface of the copper busbar, so that the copper busbar can be automatically positioned on the drawing center line, and at the same time, it can effectively prevent the copper busbar from shifting or tilting during the feeding process, ensuring the stability of the drawing process.
[0024] refer to Figure 1 and Figure 4The straightening assembly includes three support frames 15 mounted on top of two support plates 3. Symmetrical openings are provided on the side walls at both ends of the three support frames 15, and slide rods 16 are installed inside the openings. Threaded rods 17 are installed in threaded holes at the top of the support frames 15. One end of each threaded rod 17 is connected to a fixing frame 18. Slider blocks at both ends of the fixing frames 18 are adapted to the slide rods 16. A primary straightening roller 19 is rotatably mounted on the bottom of the first fixing frame 18, a secondary straightening roller 20 is rotatably mounted on the bottom of the second fixing frame 18, and a fine straightening roller 21 is rotatably mounted on the bottom of the third fixing frame 18. More specifically… Before the copper busbar is conveyed to the drawing mechanism 2, the threaded rod 17 is rotated to drive the fixed frame 18 to slide down the slide bar 16 through the sliders set at both ends. Then, the copper busbar passes through the primary straightening roller 19 set at the bottom of the first fixed frame 18. The primary straightening roller 19 performs preliminary straightening on the copper busbar to eliminate large bends and deformations. Then, the copper busbar passes through the secondary straightening roller 20 set at the bottom of the second fixed frame 18 to further improve the straightening accuracy. Finally, the copper busbar is finally finely straightened by the fine straightening roller 21 set at the bottom of the third fixed frame 18 to ensure that the copper busbar meets the high-precision straightness requirements.
[0025] The implementation principle of the copper busbar precision drawing device in this application embodiment is as follows: During use, before the copper busbar is conveyed to the drawing mechanism 2, the threaded rod 17 is rotated to drive the fixed frame 18 to slide downwards along the slide rod 16, allowing the copper busbar to pass through the primary straightening roller 19. The primary straightening roller 19 performs preliminary straightening of the copper busbar, eliminating significant bending and deformation. The copper busbar then passes through the secondary straightening roller 20 to further improve straightening accuracy. Finally, the precision straightening roller 21 performs final precision straightening of the copper busbar, ensuring that the copper busbar meets high-precision straightness requirements. The straightened copper busbar is then... The copper busbar is conveyed, and at the same time, the driving cylinder 14 pushes the connecting block 10 at the bottom of one of the sliding seats 7, so that the L-shaped rack plate 12 connected on one side slides along the mounting seat 11 and drives the gear 13 to rotate, thereby driving the other L-shaped rack plate 12 to slide along the mounting seat 11. This causes the two sliding seats 7 to slide towards each other along the sliding groove 6, driving the positioning roller 9 to move towards each other and contact the surface of the copper busbar. This allows the copper busbar to be automatically positioned on the drawing center line, and at the same time, it can effectively prevent the copper busbar from shifting or tilting during the feeding process, ensuring the stability of the drawing process.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
