Detailed Implementation
[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] The present application will be further described in detail below with reference to the accompanying drawings.
[0029] This application discloses a flat wire bending and forming device. Please refer to [link / reference]. Figure 1 and Figure 2 The device includes a frame 100, a base 200, a flat wire reel 300, and a rotating disk 400. The base 200 is fixedly mounted on the frame 100. The flat wire reel 300 is fixedly mounted on the base 200. The flat wire reel 300 is provided with a guide groove 310 for supporting the flat wire. The rotating disk 400 is rotatably mounted on the flat wire reel 300 and is concentrically arranged with the flat wire reel 300. The rotating disk 400 is provided with multiple twisting elements 410. The multiple twisting elements 410 are spaced apart on both sides of the guide groove 310. When the rotating disk 400 rotates, it drives the twisting elements 410 to twist the flat wire.
[0030] In use, the rotating disk 400 is fitted onto the flat wire reel 300. The rotating disk 400 can rotate around the flat wire reel 300, and the rotating disk 400 and the flat wire reel 300 are concentrically arranged. The flat wire reel 300 is provided with a guide groove 310, and multiple twisting elements 410 on the rotating disk 400 are distributed on both sides of the guide groove 310. When the flat wire passes through the guide groove 310, a part of the flat wire first extends out of the guide groove 310 and is placed above the rotating disk 400. When the rotating disk 400 rotates clockwise or counterclockwise, it drives the twisting column to twist the flat wire alternately in the clockwise or counterclockwise direction. The flat wire is bent into shape under the pressure of the twisting elements 410.
[0031] Specifically, when the flat wire bending and forming device disclosed in this application is used, the guide groove 310 is arranged along the horizontal axis of the flat wire disc 300, and the width of the guide groove 310 is adapted to the width of the flat wire to ensure that the flat wire will not fall off the guide groove 310 when it is placed on the guide groove 310. The flat wire is inserted into the guide groove 310 from one end and extends out of the guide groove 310. Then, the rotating disk 400 is rotated clockwise, which drives the twisting member 410 near the bottom of the flat wire groove 810 to move from the bottom of the flat wire disk 300 to the top of the flat wire disk 300, twisting the flat wire towards the top of the flat wire disk 300. The rotating disk 400 is rotated counterclockwise, which drives the twisting member 410 near the top of the flat wire disk 300 to move from the top of the flat wire disk 300 to the bottom of the flat wire disk 300, twisting the flat wire towards the bottom of the flat wire disk 300. By adjusting the rotation angle of the rotating disk 400, the twisting angle of the flat wire is adjusted. At the same time, the rotating disk 400 is rotated alternately to twist the flat wire alternately in the clockwise and counterclockwise directions, flexibly twisting the shape of the flat wire.
[0032] In this embodiment, please refer to Figure 1 The wire twisting device can cooperate with the flat wire feeding structure. The feeding structure and the flat wire twisting device are arranged sequentially along the moving direction of the flat wire. The feeding structure is provided with a feeding platform 800, and the flat wire groove 810 on the feeding platform 800 and the guide groove 310 on the flat wire reel 300 are at the same horizontal height; the twisting component 410 adopts a smooth twisting post; the twisting post is arranged on both sides of the outlet end of the guide groove 310. In use, when the flat wire moves from the feeding platform 800 to the guide groove 310 and extends from the outlet end of the guide groove 310, the rotating disk 400 is rotated alternately clockwise or counterclockwise, and the rotating disk 400 drives the twisting posts on both sides of the outlet end to twist the flat wire in the clockwise or counterclockwise direction.
[0033] Specifically, the outlet end of the flat wire groove 810 on the wire feeding platform 800 extends to the inlet end of the guide groove 310 and is horizontally positioned with the inlet end of the guide groove 310, allowing the flat wire to smoothly enter the guide groove 310 from the flat wire groove 810 on the wire feeding platform 800. When a portion of the flat wire extends from the outlet end of the guide groove 310, the rotating disk 400 is rotated alternately, causing the twisting posts on both sides of the outlet end to alternately twist the flat wire. For example, adjusting the rotating disk 400 to rotate 45 degrees causes the twisting post near the bottom of the guide groove 310 to twist the flat wire 45 degrees clockwise. Subsequently, adjusting the rotating disk 400 to rotate 90 degrees causes the twisting post near the top of the guide groove 310 to twist the flat wire 45 degrees counterclockwise, thereby twisting the flat wire into an "S"-shaped form. In actual use, the angle of each bend of the flat wire is determined according to the target shape of the flat wire, and then the rotation direction and angle of the rotating disk 400 are adjusted according to each bend angle, so that the twisting column twists the flat wire clockwise or counterclockwise alternately to twist the flat wire into different shapes, which also improves the bending efficiency of the flat wire.
[0034] Please refer to another embodiment of this utility model. Figure 2 and Figure 3 The diameter of the flat wire reel 300 is smaller than the diameter of the rotating disk 400. Specifically, in actual use, the diameter of the rotating disk 400 is larger than the diameter of the flat wire reel 300. The rotating disk 400 is rotatably mounted on the rotating disk 300. The twisting member 410 is located at the edge of the rotating disk 400. The rotating disk 400 is rotated alternately to drive the twisting member 410 to twist the flat wire alternately.
[0035] In this embodiment, the two ends of the guide groove 310 are the inlet end and the outlet end, respectively. Both the inlet end and the outlet end are trumpet-shaped, with the diameter of the inlet end being smaller than that of the outlet end. Setting the inlet of the guide groove 310 to be trumpet-shaped and having a smaller diameter ensures that the flat wire can smoothly transition from the wire feeding structure to the flat wire reel 300, preventing the end of the flat wire from colliding with the groove wall at the inlet end of the guide groove 310 when it enters, thus avoiding damage to the flat wire. Simultaneously, it ensures that the flat wire can stably pass through the guide groove 310, preventing it from falling off. Conversely, setting the outlet end of the flat wire to be trumpet-shaped and having a larger diameter facilitates bending and shaping the flat wire, allowing it to be precisely bent to a predetermined angle to form the target shape, preventing excessive compression between the flat wire and the outlet end of the guide groove 310 during bending, which could cause the flat wire to break.
[0036] In another embodiment of this utility model, please refer to Figure 2 The twisting device further includes a fixing disc 500; the fixing disc 500 has a first screw hole 510; the flat wire spool 300 has a second screw hole 320 corresponding to the first screw hole 510; a bolt passes through the first screw hole 510 and the second screw hole 320 to screw the fixing disc 500 and the flat wire spool 300 together. Specifically, in actual use, the flat wire spool 300 and the fixing disc 500 are fixed by bolts passing through the first screw hole 510 and the second screw hole 320, thereby covering the top of the guide groove 310 with the fixing disc 500, protecting the flat wire, preventing the flat wire from falling out of the guide groove 310, and ensuring the smoothness of the flat wire twisting process. In this embodiment, the second screw holes 320 are spaced apart on both sides of the guide groove 310, and the first screw holes 510 are correspondingly spaced on both sides of the guide groove 310, ensuring that the flat wire spool 300 is subjected to uniform force.
[0037] In this embodiment, please refer to Figure 2 The diameter of the fixed plate 500 is less than or equal to the diameter of the flat wire plate 300, that is, the diameter of the fixed plate 500 is also less than the diameter of the rotating plate 400. This ensures that the fixed plate 500 can protect the flat wire and avoid collision with the twisting member 410 set on the rotating plate 400 due to the protective plate being too large, which would affect the twisting member 410 to twist and bend the flat wire.
[0038] In another embodiment of this utility model, please refer to and Figure 2 The flat wire bending and forming device further includes a connecting block 600; one end of the connecting block 600 is connected to the fixed plate 500, and the other end is connected to the frame 100. Specifically, in actual use, one end of the connecting block 600 is connected to the top of the frame 100, and the other end is connected to the fixed plate 500 to improve the connection rigidity of the fixed plate 500, further ensuring that the fixed plate 500 can stably fix the flat wire disc 300, preventing the flat wire disc 300 from shifting during the twisting process, thereby improving the twisting accuracy of the flat wire.
[0039] In this embodiment, the fixed disk 500 is further provided with a third screw hole (not shown in the figure); the connecting block 600 is provided with a fourth screw hole 610 corresponding to the third screw hole; the fixed disk 500 and the connecting block 600 are screwed together by bolts passing through the third screw hole and the fourth screw hole 610. Specifically, in actual use, the connecting block 600 is shaped like an "L", with one end extending to the top of the frame 100 and connecting to the frame 100, and the other end extending to the surface of the fixed disk 500. The connecting block 600 is connected to the fixed disk 500 by bolts passing through the third screw hole and the fourth screw hole 610.
[0040] In this embodiment, please refer to Figure 1 and Figure 2 The frame 100 is equipped with a drive motor 700; the drive motor 700 is connected to the rotating disk 400 for driving the rotating disk 400 to rotate. In actual use, the rotation angle of the rotating disk 400 is adjusted by adjusting the on and off states of the drive motor 700, thereby adjusting the bending angle of the flat wire.
[0041] In summary, this utility model discloses a flat wire bending and forming device, comprising a frame, a base, and a rotating disk; the base is fixedly mounted on the frame; the flat wire disk is fixedly mounted on the base; the flat wire disk has a guide groove for supporting the flat wire; the rotating disk is rotatably mounted on the flat wire disk and concentrically arranged with the flat wire disk; the rotating disk has multiple twisting elements; the multiple twisting elements are spaced apart on both sides of the guide groove; wherein, the rotation of the rotating disk drives the twisting elements to twist the flat wire. This application provides multiple twisting elements on the rotating disk, and by rotating the rotating disk clockwise or counterclockwise, the multiple twisting elements simultaneously twist the flat wire in different directions to quickly twist the flat wire into a predetermined shape, solving the problems of low flat wire bending efficiency, limited bending shape, and inability to flexibly adapt to stator slots.
