A columnar first column 202 is provided on the upper surface of the first disc body 201, and the outer diameter of the first column 202 is adapted to the inner diameter of the inner shaping ring hole 101, and a connecting thread section 203 is provided on the top of the first column 202, and a locking nut 70 is provided on the connecting thread section 203.

[0020] The pressing fastening assembly 50 includes a pair of detachable pressing clamps 51, and the pressing clamps 51 include a "C"-shaped pressing arc strip 511. The upper part of the inner wall of the pressing arc strip 511 is provided with an annular pressing right-angle step 5111, and the pressing right-angle step 5111 abuts against the lower end surface of the iron core 801 of the motor stator. The two ends of the pressing arc strip 511 are provided with pressing connectors 512, and the pressing connectors 512 are provided with pressing connection holes 513. The pressing connection holes 513 are provided with pressing connection screws 52. The lower pressing die ring 60 includes an annular lower pressing ring body 61 , and an annular lower pressing flange 62 is disposed on the upper end surface of the lower pressing ring body 61 .

[0021] It should be noted that the cross sections of the upper pressing right-angle step 4111 and the lower pressing right-angle step 5111 are right angles.

[0022] In addition, the upper pressing ring body 31 and the upper pressing flange 32 are provided with wiring slots 33. These wiring slots 33 are used for winding wiring to prevent the copper wire from being crushed.

[0023] The working method of the motor stator winding shaping device is described below, including the following steps: Step S1: Figure 1 , Figure 7 and Figure 8 As shown, the motor stator 80 to be shaped is placed above the inner shaping seat 20, so that the plate body presses the right-angle step 2011 against the lower end surface of the iron core 801; Step S2, placing the inner shaping ring 10 above the motor stator 80, and allowing the first column 202 to penetrate the motor stator 80 and the inner shaping ring hole 101; Step S3, screw the locking nut 70 onto the connecting threaded section 203, and tighten the locking nut 70 so that the lower end surface of the inner shaping ring 10 is pressed against the upper end surface of the iron core 801; Step S4, installing the upper pressing fastening assembly 40. The specific method is: clamp the outer wall of the iron core 801 with a pair of upper pressing clamps 41, and at the same time, make the upper pressing right-angle step 4111 of the upper pressing clamps 41 press against the upper end surface of the iron core 801 of the motor stator, and tighten the upper pressing connection screws 42; Step S5, installing the pressing fastening assembly 50. The specific method is: clamp the outer wall of the iron core 801 with a pair of pressing clamps 51, and at the same time, make the pressing right-angle step 5111 of the pressing clamps 51 abut against the lower end surface of the iron core 801 of the motor stator, and tighten the pressing connection screws 52; Step S6, installing the upper pressing die ring 30 on the upper part of the upper pressing fastening assembly 40, so that the upper pressing flange 32 of the upper pressing die ring 30 falls into the gap between the upper pressing clamping strip 41 and the inner shaping ring 10, and the lower end surface of the upper pressing flange 32 abuts against the upper end surface of the winding 802; Step S7, install the lower pressing die ring 60 at the lower part of the lower pressing fastening assembly 50, so that the lower pressing flange 62 of the lower pressing die ring 60 falls into the gap between the lower pressing clamping strip 51 and the inner shaping seat 20, and the upper end surface of the lower pressing flange 62 abuts against the lower end surface of the winding 802. At this point, the assembly of the shaping device is completed, as shown in FIG. Figure 8 As shown, at this time, the protruding height D1 of the winding 802; Step S8: Fig. 9 and Fig.10 As shown, pressure F is applied to the upper die ring 30 and the lower die ring 60, so that the upper die ring 30 and the lower die ring 60 move relative to each other. At the same time, the winding 802 in the first shaping space S1 and the second shaping space S2 is shaped, as shown in FIG. Fig.10 As shown, after shaping, the protruding height D2 of the winding 802 is less than Figure 8 The protruding height D1 of the winding 802 in FIG. That is, the winding 802 is shaped into a flat regular rectangle.

[0024] It should be pointed out that in Figure 8 In the figure, the lower end surface of the upper die ring 30, the inner wall of the upper pressing fastening assembly 40 and the outer wall of the inner shaping ring 10 constitute the first shaping space S1 for shaping the winding 802 of the motor stator, and the upper end surface of the lower die ring 60, the inner wall of the lower pressing fastening assembly 50 and the outer wall of the inner shaping seat 20 constitute the second shaping space S2 for shaping the winding 802 of the motor stator. The size of the first shaping space S1 and the second shaping space S2 is larger than the space occupied by the corresponding winding 802 of the motor stator. Of course, here the first shaping space S1 is compared with the upper part of the winding 802 that can be pressed, and for the same reason, here the second shaping space S2 is compared with the lower part of the winding 802 that can be pressed.

[0025] In addition, the cross-sections of the first shaping space S1 and the second shaping space S2 are both rectangular, but they can also be other shapes.

[0026] Since the size of the first shaping space S1 and the second shaping space S2 is larger than the portion of the winding 802 to be pressed, the enameled wire distributed on the outermost side of the winding 802 can be effectively prevented from being damaged during the pressing process. In addition, during the pressing process, since the iron core 801 of the motor stator 80 is completely fixed, the iron core 801 is prevented from shifting, and the shape of the winding 802 obtained by pressing is more regular and consistent, thereby improving the quality of the product.

[0027] like Figures 11 to 14 FIG. 2 is another embodiment of the motor stator winding shaping device of the present invention. Different from the first embodiment, the upper end surface of the upper pressure ring body 31 is provided with a plurality of upper adjustment screw holes 311, and the upper adjustment screw holes 311 are provided with upper adjustment screws 34, and the lower end surface of the lower pressure ring body 61 is provided with a plurality of lower adjustment screw holes 611, and the lower adjustment screw holes 611 are provided with lower adjustment screws 64.

[0028] The distance between the upper die ring 30 and the upper pressing fastening assembly 40 can be adjusted by the upper adjusting screw 34, thereby accurately controlling the pressing stroke of the upper die ring 30. Similarly, the distance between the lower die ring 60 and the lower pressing fastening assembly 50 can be adjusted by the lower adjusting screw hole 611, thereby accurately controlling the pressing stroke of the lower die ring 60. By controlling the pressing strokes of the upper die ring 30 and the lower die ring 60, the pressing degree of the winding 802 of the motor stator can be accurately controlled.

[0029] Obviously, the embodiments described above are only part of the embodiments of the present application, rather than all of the embodiments. The drawings provide preferred embodiments of the present application, but do not limit the patent scope of the present application.
