Description

Technical Field

[0001] This utility model relates to the field of busbar bending and forming technology, and in particular to a precision bending and forming device for new energy busbars. Background Technology

[0002] Busbars are key electrical components used for power transmission and distribution, primarily applied in new energy fields such as new energy vehicles, power generation, and energy storage systems. Their core function is to efficiently and safely transmit large currents, connect multiple electrical devices or modules, and ensure efficient power distribution.

[0003] New energy busbars are the "blood vessels" of new energy power systems, and their performance directly affects system efficiency, safety, and cost. In new energy equipment, due to limited internal space, busbars need to be bent to avoid other components and achieve a compact layout. Bending can also shorten the current path and reduce inductance. Nowadays, the production capacity in the new energy field is expanding rapidly. Manual bending is inefficient and the yield is unstable. Therefore, a precision bending and forming device for new energy busbars is needed to improve the processing efficiency and accuracy of busbars.

[0004] Currently, the structure of precision bending and forming devices for new energy busbars on the market includes a frame and a bending mechanism. The frame supports the various mechanisms of the bending and forming device, and the bending mechanism uses a motor to perform plastic deformation on the busbars. Because this device relies on manual loading and unloading during use, its efficiency is low. To solve the above problem, a conveyor device is usually used to transport the busbars, thereby realizing the automatic loading of the busbars. However, in actual use, it is not convenient to fix the busbars, which causes displacement deviations in the busbars during bending and forming, reducing the processing accuracy of the busbars, reducing the practicality of the device, and failing to meet the needs of users.

Detailed Implementation

[0032] 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.

[0033] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a precision bending and forming device for new energy busbars, comprising a workbench 1 and a transmission belt 17. A chassis 21 is provided on the top right side of the workbench 1, and a wheel 22 is rotatably connected to the top of the chassis 21. A bending table 26 is fixedly connected to the top of the chassis 21 through the wheel 22. The wheel 22 can rotate between the chassis 21 and the bending table 26. A housing 3 is fixedly connected to the top of the workbench 1. A first motor 4 is fixedly connected to the upper middle part of the right side of the front wall of the housing 3. The output end of the first motor 4 passes through the housing 3 and is fixedly connected to a connecting shaft 5. The first motor 4 can drive the connecting shaft 5 to rotate. A drive bevel gear 6 is fixedly connected to both the front and rear sides of the outer wall of the connecting shaft 5. When the connecting shaft 5 rotates, the drive bevel gear 6 rotates together. Two bidirectional threaded rods 8 are rotatably connected to both the front and rear sides of the interior of the housing 3. The right end of each of the 8 is fixedly connected with a driven bevel gear 7. Two driving bevel gears 6 are respectively meshed with the corresponding driven bevel gears 7. The driving bevel gears 6 can drive the bidirectional threaded rods 8 through the driven bevel gears 7. The outer walls of the two bidirectional threaded rods 8 are threaded with sliders 9 on the left and right sides. The sliders 9 on both sides move in opposite directions through the bidirectional threaded rods 8. One side of each of the multiple sliders 9 is rotatably connected with a linkage rod 10. The movement of the sliders 9 can drive the linkage rod 10 to move. The front and rear sides of the interior of the housing 3 are provided with extrusion plates 12. The left and right ends of the opposite side of the extrusion plates 12 are fixedly connected with connecting blocks 11. The multiple connecting blocks 11 are respectively rotatably connected with the corresponding linkage rods 10. The linkage rods 10 rotate between the connecting blocks 11 and the sliders 9. The front and rear sides of the interior wall of the housing 3 are provided with sliding grooves 29. One side of each of the multiple sliders 9 is slidably connected inside the sliding grooves 29.

[0034] Specifically, when the device bends the busbar, after the busbar is sent to the bending table 26 by the transmission belt 17, in order to prevent the busbar from shifting under bending force and affecting the accuracy, the first motor 4 is started to drive the connecting shaft 5 to rotate, thereby driving the front and rear active bevel gears 6 and the corresponding driven bevel gears 7 to rotate, converting the radial rotation into axial rotation, thereby driving the bidirectional threaded rod 8 to rotate, so that the two side sliders 9 move in opposite directions along the bidirectional threaded rod 8 in the slide groove 29. The slide groove 29 guides and limits the sliders 9. Then, the two side linkage rods 10 rotate between the sliders 9 and the connecting block 11, and the two side linkage rods 10 can push the corresponding extrusion plate 12 to press together towards the middle, thereby completing the extrusion and fixing of the busbar, so that the busbar will not have displacement deviation during bending and forming, thus improving the processing accuracy.

[0035] Reference Figure 1 , Figure 5 and Figure 6The clamping mechanism 2 includes an inner cavity 201, which is located on the right side inside the workbench 1. A connecting rod 202 is rotatably connected to the right side of the front wall of the workbench 1. The rear end of the connecting rod 202 passes through the workbench 1 and is fixedly connected to a worm gear 203. The connecting rod 202 can drive the worm gear 203 to rotate. A drive shaft 204 is rotatably connected to the middle of the bottom inner side of the inner cavity 201. A worm wheel 205 is fixedly connected to the middle outer side of the drive shaft 204. The worm gear 203 meshes with the worm wheel 205, and the worm gear 203 can drive the worm wheel 205 to rotate. A rotating disk 206 is fixedly connected to the top end of the drive shaft 204. The worm wheel 205 drives the rotating disk 206 to rotate through the drive shaft 204. The four corners at the bottom of the rotating disk 206 are... Each of the first connecting pins 208 is rotatably connected, and right-angle connecting rods 207 are fixedly connected to the outer side of each of the first connecting pins 208. The rotation of the rotating disk 206 can drive the right-angle connecting rods 207 to move. Slide rails 210 are provided around the top right side of the workbench 1. Clamps 211 are slidably connected inside each of the slide rails 210. The clamps 211 can slide along the slide rails 210. Second connecting pins 209 are rotatably connected to the bottom of each of the clamps 211. Each of the second connecting pins 209 is fixedly connected to the corresponding right-angle connecting rods 207. The right-angle connecting rods 207 can pull the clamps 211 to move. A knob 20 is fixedly connected to the front end of the connecting rod 202. Protective pads 28 are fixedly connected to one side of each of the clamps 211.

[0036] Specifically, rotating the knob 20 drives the connecting rod 202, which in turn drives the worm gear 203 to rotate. The worm gear 203 drives the worm wheel 205 to rotate, and the worm wheel 205 drives the rotating disk 206 to rotate via the transmission shaft 204. The rotating disk 206 is linked to the clamp 211 via the right-angle connecting rod 207. When the rotating disk 206 rotates, the right-angle connecting rod 207 can rotate around the rotating disk 206 to drive the clamp 211 to move along the slide rail 210, so that multiple clamps 211 can converge towards the center and move away from each other. This allows for quick clamping and releasing of the mold, making it convenient for workers to change the mold.

[0037] Reference Figure 1 , Figure 5 and Figure 6 A boss 23 is fixedly connected to the outer side of the wheel 22. A roller 24 is rotatably connected to the top of the boss 23, which can bend the busbar. A third motor 27 is fixedly connected to the bottom rear side of the inner cavity 201. The output end of the third motor 27 passes through the inner cavity 201 and is fixedly connected to a transmission wheel 25. The wheel 22 is meshed with the transmission wheel 25. The third motor 27 can drive the wheel 22 to rotate through the transmission wheel 25. A controller 13 is fixedly connected to the front middle of the housing 3. The controller 13 is electrically connected to the first motor 4, the second motor 14 and the third motor 27 respectively.

[0038] Specifically, the controller 13 can control the operating status of the first motor 4, the second motor 14 and the third motor 27. By starting the third motor 27, the transmission wheel 25 is driven to rotate. Subsequently, the transmission wheel 25 drives the wheel disk 22 to rotate, and at the same time drives the boss 23 and the roller shaft 24 to rotate around the wheel disk 22, thereby realizing the bending effect of the roller shaft 24 on the busbar.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A mounting bracket 15 is fixedly connected to the top left side of the workbench 1. Rotating rods 16 are rotatably connected to the left and right sides inside the mounting bracket 15. The two rotating rods 16 are connected by a transmission belt 17. The rotation of the rotating rods 16 on both sides can drive the transmission belt 17 to move, thereby conveying the busbar. A second motor 14 is fixedly connected to the left side of the front wall of the mounting bracket 15. The output end of the second motor 14 passes through the mounting bracket 15 and is fixedly connected to the left rotating rod 16. The second motor 14 can drive the left rotating rod 16 to rotate. Washers 18 are fixedly connected to the bottom front and rear ends and left and right sides of the mounting bracket 15. Screws 19 are threaded to the top of the multiple washers 18. The bottom end of the screws 19 passes through the washers 18 and is threaded to the workbench 1.

[0040] Specifically, by starting the second motor 14, the left rotating rod 16 is driven to rotate. Then, the left rotating rod 16 rotates together with the right rotating rod 16 through the transmission belt 17. The transmission belt 17 can realize the function of conveying the busbar. The pads 18 and screws 19 on both sides of the mounting bracket 15 can fix the mounting bracket 15 to the top of the workbench 1.

[0041] Working principle: When the device needs to bend the busbar, the busbar is sent to the bending table 26 by the transmission belt 17. To prevent the busbar from being displaced by the force, the first motor 4 is started to drive the connecting shaft 5 to rotate. The connecting shaft 5 drives the active bevel gears 6 on both sides to rotate. Then the active bevel gears 6 drive the corresponding driven bevel gears 7 to rotate. The driven bevel gears 7 drive the corresponding bidirectional threaded rods 8 to rotate. Then the sliders 9 on both sides move in the opposite direction along the corresponding bidirectional threaded rods 8. The linkage rods 10 on both sides will be pushed and rotate between the corresponding sliders 9 and the corresponding connecting blocks 11, so that the pushing force can be transmitted to the side extrusion plates 12. At the same time, the extrusion plates 12 on both sides can be pushed towards the middle, thereby achieving the extrusion effect and completing the extrusion and fixing of the busbar. This prevents the busbar from having displacement deviation during bending and forming, and improves the processing accuracy.

[0042] Furthermore, when it is necessary to change the mold, by rotating the connecting rod 202, the connecting rod 202 rotates, which drives the worm gear 203 to rotate. The worm gear 203 then drives the worm wheel 205 to rotate. The worm wheel 205 can drive the rotating disk 206 through the transmission shaft 204. The rotating disk 206 pulls the right-angle connecting rod 207 through the first connecting pin 208. The right-angle connecting rod 207 then drives the clamp 211 to slide in the slide rail 210 in a linear motion, moving towards or away from each other towards the center, thereby quickly releasing and clamping the mold, making it convenient for workers to change the mold.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
