The sheer number of these widely used motors creates a significant demand for their production and repair, including a large number of rotor winding copper strip end caps required during repair. Currently, there are no specialized tools for repairing rotor winding copper strip end caps. Generally, common tools such as vises, wrenches, and hammers are used on molds, relying entirely on the worker's skill and experience. This results in inaccurate control of shape and dimensions, making it difficult to achieve uniformity. This is time-consuming and labor-intensive, reducing efficiency and compromising quality. It can even cause short circuits in the motor rotor windings, leading to complete scrapping and increased equipment procurement costs for companies. Therefore, designing a tool capable of manufacturing YZR series motor rotor winding copper strip end caps is essential. Utility Model Content

[0025] This utility model consists of a fixed platform 2, a fixing bolt 3, a fixed mold base 4, a head sleeve mold 5, a forming baffle 6, a rotating mold 7, a handle base 8, a rotating handle 9, a positioning groove 10, a positioning key 11, a fixing nut 15, and a positioning rod 16.
[0026] Figure 1 , 2 As shown in Figure 5, the fixed platform 2 is a square steel plate, and the fixed mold base 4 is a flat cylinder. The fixed mold base 4 is welded to the center of the fixed platform 2. The head-mounted mold 5 is a disc. The top surface of the fixed mold base 4 has a rectangular positioning groove 10 at its center, and the bottom surface of the head-mounted mold 5 has a positioning key 11 that matches the positioning groove 10 of the fixed mold base 4. The positioning key 11 is embedded in the positioning groove 10 to connect the head-mounted mold 5 and the fixed mold base 4.
[0027] Figure 1 , 2 As shown in Figures 3 and 4, the top surface of the disc of the head-mounted mold 5 is connected to the head-mounted fan-shaped block 12. There is a forming baffle 6 on the outer side of one side wall of the head-mounted fan-shaped block 12. The surface of the forming baffle 6 is parallel to the side wall of the head-mounted fan-shaped block 12. The lower end of the forming baffle 6 is welded to the top surface of the disc of the head-mounted mold 5.
[0028] Figure 3 , 4Figure 8 shows that the forming baffle 6 is located on the center diameter of the disc of the parallel head sleeve mold 5. The length of the forming baffle 6 is half the length of the parallel head sleeve copper plate 17. The thickness of the forming baffle 6 matches the middle gap of the parallel head sleeve copper plate 17. The gap between the forming baffle 6 and the side wall of the parallel head sleeve fan-shaped block 12 matches the thickness of the parallel head sleeve copper plate 17 used to make the parallel head sleeve. The parallel head sleeve copper plate 17 is placed in the gap between the forming baffle 6 and the side wall of the parallel head sleeve fan-shaped block 12. The function of the forming baffle 6 is to position the parallel head sleeve copper plate 17 used to make the parallel head sleeve, and then the rotating mold 7 bends the parallel head sleeve copper plate 17.
[0029] Figure 1 , 6 Figure 7 shows that the rotating mold 7 is a disc, and the bottom surface of the disc of the rotating mold 7 has a rotating sector block 13. The disc and rotating sector block 13 of the rotating mold 7 are the same as the disc and sector block 12 of the parallel head sleeve mold 5. The disc of the rotating mold 7 is above the disc of the parallel head sleeve mold 5 and faces the disc of the parallel head sleeve mold 5. The rotating sector block 13 is below the disc of the rotating mold 7 and is offset parallel to the sector block 12 of the parallel head sleeve. The sector block 12 of the parallel head sleeve and the rotating sector block 13 together provide support for the rotating mold 7. At the same time, when the rotating sector block 13 of the rotating mold 7 rotates, it can bend the copper plate 17 of the parallel head sleeve along the forming baffle 6 to complete the operation of making the parallel head sleeve.
[0030] Figure 4 , 7 The arcs of the parallel-head sleeve sector block 12 and the rotating sector block 13 coincide with the circumferences of the disks of the parallel-head mold 5 and the rotating mold 7. The centers of the circumferences of the parallel-head sleeve sector block 12 and the rotating sector block 13 are not aligned with the centers of the circumferences of the disks of the parallel-head mold 5 and the rotating mold 7, meaning their diameters are different. The two sides of the two sector blocks are located inside the center diameters of the disks of the parallel-head mold 5 and the rotating mold 7, respectively. The area of the two sector blocks is less than 1 / 4 of the area of the disks of the parallel-head mold 5 and the rotating mold 7. Furthermore, the included angle between the two side walls of the parallel-head sleeve sector block 12 and the rotating sector block 13 is 90 degrees. This structure allows the rotating sector block 13 to rotate around the forming baffle 6, bending the parallel-head sleeve copper plate 17.
[0031] Figure 1 , 6As shown in Figure 7, the handle base 8 is fixedly connected to the top surface of the disc of the rotary mold 7. The handle base 8 has a dual function. On one hand, a vertical positioning rod 9 is fixed to the upper end of the handle base 8, which is used to connect to the bench drill. On the other hand, the side wall of the handle base 8 has a screw hole 18, and the front end of the rotary handle 9 has a screw 19. The thread of the screw 19 matches the screw hole 18 of the handle base 8, and the screw 19 at the front end of the rotary handle 9 is threadedly connected to the screw hole 18 of the handle base 8. Rotating the rotary handle 9 can rotate the handle base 8, which can drive the rotary mold 7 to rotate.
[0032] Figure 9 As shown, the fixed platform 2 of this utility model is fixed on the bench drill table 1. The fixed platform 2 has fixing holes 14 at its four corners, and the fixing holes 14 are connected to the table surface of the bench drill table 1 by fixing bolts 3 and fixing nuts 15. At the same time, the upper end of the positioning rod 9 at the upper end of the handle seat 8 is locked to the bench drill chuck, fixing the tool to the bench drill for stable operation.
[0033] The working process of this utility model is as follows:
[0034] First, fix the fixed platform 2 to the bench drill table 1 with fixing bolts 3 and fixing nuts 15, and lock the upper end of the positioning rod 9 at the upper end of the handle seat 8 to the bench drill chuck to ensure stable operation.
[0035] The second step is to rotate the rotating handle 9, and the handle seat 8 drives the rotating mold 7 to rotate, so that the rotating sector block 13 under the disc of the rotating mold 7 rotates to a position parallel to the parallel head sleeve sector block 12, away from the forming baffle 6.
[0036] The third step is to place the copper plate 17 of the parallel head sleeve into the gap between the forming baffle 6 and the side wall of the parallel head sleeve fan block 12, and the length of the front end of the copper plate 17 of the parallel head sleeve extending out of the forming baffle 12 is equal to the length that needs to be bent.
[0037] Fourth step, rotate the rotating handle 9, the handle seat 8 drives the rotating mold 7 to rotate, the rotating fan block 13 under the disc of the rotating mold 7 rotates to above the front end of the copper plate 17, continue to rotate the rotating handle 9, the rotating fan block 13 presses down on the front end of the copper plate 17, the forming baffle 6 presses against the lower surface of the copper plate 17, the copper plate 17 is bent by the rotating fan block 13, the copper plate 17 bends 180 degrees around the forming baffle 6 and is parallel to the unbent part;
[0038] Fifth step, rotate the rotating handle 9 in the opposite direction, and the rotating sector block 13 of the rotating mold 7 will disengage from the bent part of the copper plate 17 and rotate to the top of the forming baffle 6 and parallel to the sector block 12.
[0039] Step 6: Take out the copper plate 17 between the forming baffle 6 and the fan-shaped block 12, rotate it 180 degrees, and fit the bent part of the copper plate 17 into the back of the forming baffle 6, while the unbent part extends out of the front of the forming baffle 6.
[0040] Step 7: Repeat the action of step 4. Use the rotating fan block 13 of the rotating mold 7 to bend the unbent part of the copper plate 17 for the second time, so that the unbent part of the copper plate 17 bends 180 degrees around the forming baffle 6 and is opposite to the first bent part.
[0041] Step 8: Rotate the handle 9 in the opposite direction. The rotating fan-shaped block 13 of the rotating mold 7 will detach from the bent part of the copper plate 17 of the head sleeve. Remove the bent head sleeve from the forming baffle 5 to complete the production of the head sleeve.
