[0027] The shaping device 200 extrudes the coil winding 11 in the vertical direction to achieve further shaping of the coil winding 11 of the stator 10. The shaping device 200 comprises a positioning assembly 220, a shaping assembly 210 and a first driving device 230.

The first driving device 230 is used to drive the shaping assembly 210 to move in the vertical direction to extrude and shape the coil winding 11.

[0028] The working principle of the utility model is as follows:

[0029] Firstly, the stator 10 is placed on the vertical rod 121 of the rotary displacement device 120 of the rounding device 100, the rotary displacement device 120 drives the stator 10 to rotate and move to the shaping wheel 111 of the shaping assembly 110, so that the shaping wheel 111 contacts the coil winding 11 of the stator 10. Under the extrusion of the shaping wheel 111, the outer circumference of the coil winding 11 is rounded, so that the coil winding 11 can be embedded in the first annular groove 211 and the second annular groove 226. Then, the rounded stator 10 is placed on the positioning assembly 220 of the shaping device 200 to ensure the position of the stator 10 fixed in the vertical direction, at this time the first driving device 230 drives the shaping assembly 210 to move in the vertical direction to apply pressure to the coil winding 11 to achieve the extrusion and shaping of the coil winding 11. Through the extrusion in the vertical direction, the coil winding 11 is further shaped to achieve the required shape and size, ensuring the performance and stability of the stator 10.

[0030] In some embodiments, the positioning assembly 220 comprises a base 221, positioning columns 222, and a placement plate 223, the second annular groove 226 is located on the placement plate 223, the positioning columns 222 are arranged on the base 221 coaxially with the first annular groove 211, the positioning columns 222 are matched with the inner periphery of the stator 10, and the placement plate 223 is movably arranged on the base 221 and can move in the vertical direction, and the positioning columns 222 can enter the stator 10 when the stator 10 is placed on the placement plate 223.

[0031] The base 221 is used to support other components, and the positioning columns 222 are arranged on the base 221 coaxially with the first annular groove 211 in the shaping assembly 210. The positioning columns 222 are matched with the inner periphery of the stator 10 to ensure the stability of the stator 10 during shaping. The placement plate 223 is used to place the stator 10, and the placement plate 223 is movably arranged on the base 221 and can move in the vertical direction. This design allows the position of the placement plate 223 to be adjusted according to the height or thickness of the stator 10 to adapt to stators 10 of different sizes.

[0032] When the stator 10 is placed on the placement plate 223, the positioning columns 222 can enter the stator 10 and be matched with the inner periphery of the stator 10 to fix the position of the stator 10. This matching can be a tight fit or a loose fit. The movability of the placement plate 223 allows the operator to adjust the height of the stator 10 as needed to adapt to different shaping needs. This design of the positioning assembly 220 provides flexibility and accuracy to adapt to stators 10 of different sizes.

[0036] The main function of the sliding assembly 240 is to move the positioning assembly 220 horizontally, so that the position of the stator 10 in the shaping device can be adjusted, making it easier for the operator to move the stator 10 located in the rounding device 100 to the shaping device 200 for further operation. The sliding assembly 240 may include sliding rails, sliding blocks, guide wheels and other components that work together to achieve smooth horizontal movement.

The first sliding block 242 is a component in sliding connection with the first sliding rail 241, which moves along the first sliding rail 241 to drive the positioning assembly 220 to move horizontally. The first sliding block 242 may contain rollers or bearings to reduce friction and ensure smooth sliding movement. The first sliding block 242 is connected to the positioning assembly 220, and this connection may be achieved through bolts, welding or other mechanical connection methods to ensure that the first sliding block 242 can transmit the moving power to the positioning assembly 220. Through this connection, when the first sliding block 242 moves along the first sliding rail 241, it can drive the positioning assembly 220 to move together, achieving the adjustment of the stator 10 in the horizontal direction.

[0039] Further, the sliding assembly 240 further includes a second driving device for driving the first sliding block 242 to slide along the first sliding rail 241.

The second driving device can be an electric, pneumatic, hydraulic or manual driving system.
