Technical Field

[0001] This application relates to the field of coil processing technology, and in particular to a coil forming device for a flat wire motor. Background Technology

[0002] Currently, flat-wire motors are a type of motor that uses flat conductors (flat wires) instead of traditional round wires as winding conductors. While similar to ordinary round-wire motors in structural design and working principle, they offer significant improvements in performance, efficiency, and power density thanks to the unique advantages of flat wires, making them particularly suitable for demanding applications such as new energy vehicles and aerospace.

[0003] On the flat wire motor stator production line, the coil needs to undergo 2D forming and 3D forming sequentially before it can be inserted into the stator core slot. In traditional coil forming production lines, each coil forming process is completed using a separate set of stamping dies and drive equipment. This results in an excessive number of dies and drive equipment that need to be arranged on the coil forming production line, leading to an excessively long coil forming production line, a longer production cycle, and increased production costs. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a coil forming device for a flat wire motor.

[0026] Reference Figure 1 A coil forming device for a flat wire motor includes a frame 1 with a pad 11 on the frame 1, and a coil placed on the pad 11. The frame 1 is provided with a first forming component 2, a second forming component 3, and a third forming component 4, which form the coil.

[0027] Reference Figures 2-3 The first molding component 2 includes a support block 21 and a molding block 22. The support block 21 is bolted to the frame 1, and the molding block 22 is located on one side of the support block 21. A first molding groove 23 is formed between the support block 21 and the molding block 22. A pad block 11 is located on both sides of the support block 21 and the molding block 22. In use, the two ends of the strip coil are placed on the pad block 11, and then the molding block 22 moves towards the side closer to the support block 21. When the molding block 22 presses the support block 21 against the support block 21, the coil is formed between the support block 21 and the molding block 22.

[0028] Reference Figures 3-4To improve the ease of moving the molding block 22 closer to the support block 21, a pressure plate 12 is provided on the frame 1. The pressure plate 12 is arranged in parallel. A pressure rod 24 is provided on the side of the pressure plate 12 near the molding block 22. One end of the pressure rod 24 is connected to the pressure plate 12, and the other end extends closer to the molding block 22. A guide wheel 25 is rotatably mounted on the molding block 22, and a guide slope 241 is formed on the side of the pressure rod 24 near the guide wheel 25. The slope direction of the guide slope 241 is towards the side near the guide wheel 25. In use, the pressure plate 12 moves closer to the molding block 22, and the pressure rod 24 on the pressure plate 12 abuts against the guide wheel 25. As the pressure plate 12 moves further closer to the molding block 22, the pressure rod 24 pushes the molding block 22 closer to the support block 21.

[0029] Furthermore, a reset rod 221 is provided on the molding block 22. One end of the reset rod 221 is connected to the molding block 22, and the other end passes through the frame 1. A reset spring 222 is provided between the reset rod 221 and the frame 1. The reset spring 222 is sleeved on the reset rod 221 and abuts against the reset rod 221 and the bracket. When the molding block 22 moves to one side of the support block 21, the reset spring 222 is compressed. When the pressure rod 24 moves away from the guide wheel 25, the molding block 22 is reset under the action of the reset spring 222.

[0030] The second forming component 3 includes a support plate 31 and a forming plate 32. The support plate 31 is located between the forming block 22 and the support block 22. A second forming groove 33 is formed between the support plate 31 and the forming plate 32. The thickness of the support plate 31 and the forming plate 32 is the same as the thickness of the coil, so that when the forming block 22 and the support block 21 clamp the coil, the support plate 31 and the forming plate 32 can simultaneously form the coil. Furthermore, the support plate 31 is fixedly installed on the side of the frame 1 near the forming block 22 and the support block 21, and the forming plate 32 is installed on the pressure plate 12. When the pressure plate 12 moves towards the side near the forming block 22, the forming plate 32 on the pressure plate 12 simultaneously presses the coil against the support plate 31, and the coil is formed in the second forming groove 33.

[0031] To improve the ease of movement of the pressure plate 12 on the frame 1, a first drive motor 13 and a first eccentric wheel 131 are provided on the frame 1. The first drive motor 13 is mounted on the frame 1, and the first eccentric wheel 131 is rotatably mounted on the frame 1. In use, the first drive motor 13 drives the first eccentric wheel 131 to rotate. Furthermore, a connecting rod 132 is provided between the first eccentric wheel 131 and the pressure plate 12, with both ends of the connecting rod 132 rotatably connected to the first eccentric wheel 131 and the pressure plate 12, respectively. In use, the first drive motor 13 drives the first eccentric wheel 131 to rotate. As the first eccentric wheel 131 rotates, the connecting rod 132 drives the pressure plate 12 to rise and fall on the frame 1, thereby enabling the forming block 22 and the forming plate 32 to form the coil.

[0032] Reference Figure 5 Furthermore, the third forming component 4 includes a bending rod 41, with one bending rod 41 on each side of the pressure rod 24. A fixing block 42 is provided on the pressure plate 12, and a guide rod 43 is provided on the bending rod 41. One end of the guide rod 43 is connected to the bending rod 41, and the other end passes through the fixing block 42. A limit block 44 is provided at the end of the guide rod 43 that passes through the fixing block 42. A support spring 45 is provided between the limit block 44 and the fixing block 42. The support spring 45 is sleeved on the guide rod 43 and abuts against the limit block 44 and the fixing block 42.

[0033] Furthermore, a push plate 14 is slidably mounted on the frame 1. When the forming block 22 and the support block 21, as well as the forming plate 32 and the support plate 31, clamp the coil, the push plate 14 pushes the bending rod 41 towards the side closer to the support block 21 through the limiting block 44 and the guide rod 43, thereby causing the coil to bend. When the pressure plate 12 is raised, the limiting block 44 separates from the push plate 14. At this time, the bending rod 41 moves away from the support block 21 under the action of the support spring 45.

[0034] Furthermore, a second drive motor 15 and a second eccentric wheel 151 are provided on the frame 1. The second drive motor 15 is mounted on the frame 1, and the second eccentric wheel 151 is mounted on the output shaft of the second drive motor 15. In use, the second drive motor 15 drives the second eccentric wheel 151 to rotate. A drive rod 152 is provided on the second eccentric wheel 151, and a guide groove 141 is provided on the push plate 14. One end of the drive rod 152 is connected to the second eccentric wheel 151, and the other end passes into the guide groove 141 of the push plate 14. As the second drive motor 15 drives the second eccentric wheel 151 to rotate, the push plate 14 moves towards or away from the pressure plate 12.

[0035] 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.
