[0023] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0024] Please see Figure 1-6 According to an embodiment of the present invention, a drawing die for winding armature coils includes a horizontally arranged workbench 1. Support legs 2 are fixedly installed at the four corners of the bottom of the workbench 1. A vertical rod 3 is fixedly installed in the center area of ​​the top of the workbench 1. A horizontal plate 4 is fixedly installed at the top end of the vertical rod 3. A straight edge forming structure 5 is installed on the horizontal plate 4. Parallel slide rails 6 are symmetrically arranged along the center of the top of the workbench 1. The slide rails 6 are arranged along the axial direction of the straight edge forming structure 5. A transverse sliding seat 7 is also symmetrically arranged along the center of the top of the workbench 1. The bottom of the transverse sliding seat 7 is slidably installed on the slide rail 6. An assembly seat 9 is fixedly installed on the top of the transverse sliding seat 7. A connecting plate 10 is installed on the top of the assembly seat 9. An arc-shaped block 11 is installed on the connecting plate 10.

[0025] The position of the transverse sliding seat 7 on the worktable 1 can be changed by the slide rail 6, thereby changing the distance between the transverse sliding seat 7 and the straight edge forming structure 5. The two ends of the armature coil can be stabilized according to the specifications of the armature coil in actual work, which facilitates subsequent winding.

[0026] A slide block 8 is fixedly installed at the bottom of the transverse sliding seat 7, and the slide block 8 is slidably mounted on the slide rail 6. The slide block 8 is used to connect the slide rail 6 and the transverse sliding seat 7, which facilitates the sliding adjustment of the transverse sliding seat 7.

[0027] A servo motor 12 is installed at the bottom center of the workbench 1. The output shaft of the servo motor 12 passes through the workbench 1 and is fixedly connected to an adjustment shaft 13. The top end of the adjustment shaft 13 is rotatably mounted on the bottom of the horizontal plate 4 through a bearing seat 14. A gear 15 is fixedly installed on the outside of the adjustment shaft 13. A rack 16 is fixedly installed on one side of the top of the transverse sliding seat 7. The rack 16 is arranged along the length of the slide rail 6 and meshes with the gear 15. The racks 16 on the two transverse sliding seats 7 are centrally symmetrical about the center of the gear 15. When the servo motor 12 is started, it drives the gear 15 to rotate via the adjusting shaft 13. The rotation of the gear 15 drives the rack 16 that meshes with it to move. When the rack 16 moves, it pulls the transverse seat 7 to move synchronously, thereby realizing the position adjustment of the connecting plate 10 and the arc block 11. Since the two racks 16 are centrally symmetrically arranged on the outside of the gear 15, the movement directions of the two racks 16 are always opposite, thus enabling them to move closer or further away from each other synchronously.

[0028] An extension arm 71 is integrally provided on one side of the top of the transverse sliding seat 7. The extension arm 71 is arranged along the length direction of the slide rail 6, and the top of the extension arm 71 has an assembly groove 72 arranged along its length direction. The rack 16 is fixedly installed in the assembly groove 72. The extension arm 71 can provide support for the installation of the rack 16.

[0029] The top of the mounting base 9 is symmetrically equipped with guide rails 17 arranged along the length of the slide rail 6. The bottom of the connecting plate 10 is provided with a guide groove 18, and the connecting plate 10 is slidably mounted on the guide rail 17 through the guide groove 18. The position of the connecting plate 10 on the mounting base 9 can be changed by the guide groove 18, so as to adjust it separately according to the length of the two ends of the armature coil, so that the two connecting plates 10 and the arc block 11 on both sides of the top of the workbench 1 can adapt to the winding of armature coils of different specifications.

[0030] A through hole 19 is provided on the outer wall of the connecting plate 10. The through hole 19 is provided together with the guide groove 18, and a locking bolt 20 is screwed into the through hole 19. The locking bolt 20 can contact the outer wall of the guide rail 17, thereby locking the adjusted connecting plate 10.

[0031] Through the above-described solution of this utility model, the structure of this utility model is simple and reasonable, and it is quick and convenient to use. The distance between the two mounting seats 9 can be adjusted according to the specifications of different armature coils, so that the distance between the arc block 11 and the connecting plate 10 can be adjusted more conveniently. The distance between different arc blocks 11, connecting plates 10 and straight edge forming structures 5 can also be adjusted and locked by locking bolts 20, which can adapt to the winding of armature coils of more specifications.
