[0002] In the production of steering motors, copper busbars are critical conductive components, and their shape and structure directly impact the motor's performance and efficiency. Steering motors are widely used in automobiles, robots, and other automated equipment, and their reliability and performance requirements are increasingly demanding. Traditional copper busbar bending processes typically rely on manual labor, resulting in low efficiency, large errors, and long production cycles.

[0003] In existing technologies, most tooling is designed only for copper busbars of specific specifications, resulting in frequent tooling changes during the production process, increasing production costs and time. Furthermore, existing tooling often requires redesign and remanufacturing when adjusting process parameters, making it difficult to quickly respond to changes in market demand. As the manufacturing industry evolves towards intelligent and automated processes, companies are increasingly demanding greater production efficiency and flexibility. Therefore, a simple U-bending tool was proposed to address these issues. Utility Model Content

When the process parameters of the U-shaped angle of the sample need to be adjusted, it is only necessary to remake the punch to quickly complete the adjustment of the tooling, which is convenient for adjusting other process parameters.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3The utility model provides an embodiment: a simple U-shaped bending tool, comprising a base 1, a U-shaped groove for bending the material into a U-shape is provided in the middle of the base 1. Two positioning grooves 2 are provided on the top of the base 1. The function of the positioning grooves 2 is to ensure that the stamping mechanism is accurately docked and used with the bending tool when it descends, thereby ensuring the accuracy and consistency of the bending. The front end of the base 1 is slidably connected to a guide block 3, and the bottom of the guide block 3 is detachably connected to a punch 4. The outer shape of the punch 4 is U-shaped, and the punch 4 is driven downward by the descent of the guide block 3, thereby bending the material into a U-shape. A U-shaped bending ring 5 is provided on the outside of the punch 4, and one end of the U-shaped bending ring 5 is movably connected to the inner wall of the base 1. The design of the U-shaped bending ring 5 enables the material to better maintain its shape during the bending process to prevent deformation.

[0032] The punch 4 is detachably connected to two positioning pins 6, which limit the descent of the punch 4 during the bending process to prevent excessive bending. The base 1 is fixedly connected to an ejector assembly for automatically ejecting the bent material. The design of the ejector assembly allows the bent material to be automatically ejected, eliminating the need for manual removal, greatly improving work efficiency. The top of the base 1 is fixedly connected to a positioning assembly for securing the material during bending. The positioning assembly secures the material during the bending process to prevent movement, thereby ensuring accuracy and consistency in the bending process.

[0033] The ejection assembly includes multiple springs 7, the bottoms of the multiple springs 7 are fixedly connected to the inside of the base 1, and the tops of the multiple springs 7 are fixedly connected to the ejection bar 8. The outer wall of the ejection bar 8 is slidably connected to the inside of the base 1. During the bending process, the material bends downward along the U-shaped groove, thereby squeezing the ejection bar 8 and compressing the spring 7. When the external pressure is removed, the spring 7 recovers its deformation and drives the ejection bar 8 to move upward to eject the material to prevent the material from getting stuck in the U-shaped groove.

[0034] Reference Figures 2 to 4 The positioning assembly includes a plurality of slide bars 9, which can provide stable support and guidance for the entire positioning assembly. The two ends of the plurality of slide bars 9 are fixedly connected to the top of the base 1, and the outer walls of the two slide bars 9 are slidably connected to the holder 10. The holder 10 can move along the direction of the slide bars 9 on the base 1 to adapt to materials of different sizes and ensure the stability of the material during the bending process. The bottom of the two holders 10 is slidably connected to the top of the base 1. The top inner wall of the holder 10 is fixedly connected to two springs 11 (such as Figure 4As shown, the spring 2 11 is in a compressed state), and the other ends of the two springs 2 11 are fixedly connected to a pressure plate 13, and the outer wall of the pressure plate 13 is slidably connected to the inner wall of the holder 10, so that the pressure plate 13 can apply pressure to the material under the action of the spring 2 11, ensuring that the material is tightly attached to the U-shaped groove during the bending process, preventing the material from being displaced or deformed during the bending process. The inner wall of the holder 10 is fixedly connected to the limit rod 12, and the inner wall of the pressure plate 13 is slidably connected to the outer wall of the limit rod 12, thereby ensuring the stability of the pressure plate 13 when moving up and down, and also limiting the travel of the pressure plate 13 to prevent excessive compression of the material. The top of the base 1 is detachably connected to a limit assembly for fixing the positioning assembly.

[0035] The limiting assembly includes two locking blocks 15, the bottoms of the two locking blocks 15 are detachably connected to the top of the base 1, and a plurality of slots 14 are provided on the top of the base 1. The bottoms of the locking blocks 15 are detachably connected to the inside of the slots 14. After the fixture 10 moves to the corresponding position to clamp the material, the position of the fixture 10 can be fixed by inserting the locking blocks 15 into the corresponding slots 14 to prevent the fixture 10 from shifting during the bending process and causing the material to shift.

[0036] Working principle: When in use, place the material on the base 1, move the two fixers 10 to the corresponding position, pull the pressure plate 13, compress the spring 2 11, and release the pressure plate 13 when the bottom of the pressure plate 13 contacts the top of the material. The spring 2 11 restores its deformation to fix the material. Then insert the insert into the corresponding slot 14 to fix the fixer 10, thereby ensuring that the material remains stable during the bending process.

[0037] When the bending device moves downward, it drives the guide block 3 downward, thereby driving the punch 4 downward to bend the material. At this time, when the punch 4 descends to a certain position, the descent of the punch 4 is limited by the positioning pin 6 to ensure the bending angle of the material. During the bending process, the material bends downward along the U-shaped groove, thereby squeezing the ejector bar 8 and compressing the spring 1 7. When the external pressure is removed, the spring 1 7 recovers its deformation and drives the ejector bar 8 upward to eject the material, preventing the material from getting stuck in the U-shaped groove.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
