[0031] Therefore, the core of the utility model lies in designing a shaping device to compact the coil in fluffy state to form a shaped coil, thereby facilitating one-time integral embedding into the iron core.
[0032] In order to enable the personnel in the technical field to better understand the utility model scheme, the utility model is further described in detail below in combination with the drawings and specific embodiments.
[0033] Please refer to the accompanying drawings and specific embodiments Figure 2 and the accompanying drawings Figure 3 The utility model discloses a shaping device, which comprises a shaping tool and a pressing plate tool. The shaping tool comprises an annular base plate 101 and shaped teeth 102. The number of the shaped teeth 102 is multiple, and the multiple shaped teeth 102 are arranged at intervals around the central axis of the annular base plate 101. Two adjacent shaped teeth 102 form a shaped slot 103, and the number of the shaped slots 103 is equal to the number of the iron core slots of the iron core. The annular base plate 101 and the shaped teeth 102 in the embodiment are shaped according to the iron core, and the difference from the iron core is that the groove depth of the shaped slot 103 is greater than the height of the coil in the fluffy state, and the groove width of the shaped slot 103 is smaller than the groove width of the iron core slot. The coil specifically comprises a coil embedding part and a coil ring part. The coil in the fluffy state is sleeved on the shaping tool, and each coil embedding part is respectively arranged in the corresponding shaped slot 103 and will not pop out of the shaped slot 103. Optionally, the annular base plate 101 and the shaped teeth 102 are integrally formed.
[0034] The groove depth of the shaped slot 103 is the dimension of the shaped slot 103 in the axial direction of the annular base plate 101 or the dimension of the shaped slot 103 along the vertical plane of the annular base plate 101. The groove width of the shaped slot 103 is the dimension of the shaped slot 103 in the circumferential direction of the annular base plate 101.
[0035] The pressing plate tool comprises an annular pressing plate 201 and a pressing plate driving device. The annular pressing plate 201 is formed with pressing parts 202. The multiple pressing parts 202 are arranged at intervals around the central axis of the annular pressing plate 201. The pressing plate driving device drives the annular pressing plate 201 to move, so that the pressing parts 202 of the annular pressing plate 201 compact the fluffy coil in the shaped slot 103 to obtain the shaped coil. Optionally, the annular pressing plate 201 and the pressing parts 202 are integrally formed.
[0036] The pressing part 202 has a certain length in the direction perpendicular to the plane of the annular pressing plate 201. After the pressing part 202 presses the shaping coil into place, the annular pressing plate 201 is optionally abutted against the side of the shaping tooth 102 away from the annular base plate 101.
[0037] In some embodiments, the two adjacent pressing parts 202 form an avoiding hole 203 for the shaping tooth 102. The annular pressing plate 201 is sleeved on the shaping tooth 102 through the avoiding hole 203. The size of the pressing part 202 is matched with the shape of the shaping groove 103, and the shaping tooth 102 guides the movement of the annular pressing plate 201.
[0038] With the movement of the annular pressing plate, each pressing part 202 enters a shaping groove 103 to form extrusion on the coil embedding part in the shaping groove 103. The outer diameter of the annular pressing plate 201 is greater than the outer diameter of the coil in the fluffy state. While the pressing part 202 extrudes the coil embedding part, the annular pressing plate 201 extrudes the coil ring part.
[0039] Since the coil embedding part is completely located in the shaping groove 103, and the outer diameter of the annular pressing plate is greater than the outer diameter of the coil, the coil is entirely compacted in the height direction when the annular pressing plate extrudes the coil. At the same time, since the groove width of the shaping groove 103 is less than the groove width of the core groove, the width of the compacted coil embedding part is less than the width of the core groove. Therefore, the shaped coil 100 after shaping can be embedded into the core groove at one time. Compared with the prior art of layered embedding into the core groove, the one-time embedding scheme in this embodiment significantly reduces the labor intensity and difficulty of embedding the coil. At the same time, since the coil is entirely shaped and compacted by the annular pressing plate, the compacting degree of each coil embedding part of the coil is basically the same, thereby ensuring the consistency of the embedding quality.
[0040] The pressing plate driving device provides power for the movement of the annular pressing plate 201. The pressing plate driving device is arranged above the annular pressing plate 201, and drives the annular pressing plate 201 to move. The pressing plate driving device drives the annular pressing plate 201 to move towards the shaping tool to press the fluffy coil of the shaping tool; after the pressing is completed, the pressing plate driving device drives the annular pressing plate 201 to move away from the shaping tool.
[0041] The annular pressing plate 201 includes an inner ring part and an outer ring part, and the pressing plate driving device is connected with the annular pressing plate 201.

[0043] The stripping teeth 105 are arranged along the radial direction of the annular stripping plate 104, the stripping plate 104 drives the stripping teeth 105 to move in the shaping groove 103, the stripping teeth 105 are used for supporting the coil embedding part in the shaping groove 103, and the stripping teeth 105 can push out the coil embedding part in the shaping groove 103, thereby facilitating embedding the shaped coil 100 into the core groove.
[0044] The stripping plate driving device is arranged below the annular base plate 101, the stripping plate driving device drives the stripping plate 104 to move, and the stripping plate driving device is connected with the inner ring part of the stripping plate 104 through a first connecting piece. The first connecting piece is arranged along the radial direction of the annular base plate 101.
[0045] The stripping plate driving device can be a telescopic cylinder, when the telescopic rod of the telescopic cylinder is in the retracted state, the stripping teeth 105 are located in the shaping groove 103 and are used for supporting the coil embedding part in the shaping groove 103; when the telescopic rod of the telescopic cylinder is in the extended state, the stripping teeth 105 push out the shaped coil 100 from the shaping groove 103. The arrangement of the stripping plate driving device realizes automatic separation of the shaped coil 100 and the shaping groove 103, replaces manual separation, and reduces the labor intensity of coil shaping.
[0046] The stripping plate driving device is a gas cylinder or a lead screw assembly;
[0047] The pressing plate driving device is a gas cylinder or a lead screw assembly.

[0049] Optionally, the tooth width of the stripping teeth 105 is less than the groove width of the shaping groove 103, which reduces the assembly difficulty of the stripping plate 104 and the shaping tool and reduces the damage of the movement of the stripping plate 104 to the shaping tool.
[0050] The hardness of the part of the off-line tooth 105 protruding from the plane of the off-line plate 104 is lower than the hardness of the part of the off-line tooth 105 below the plane of the off-line plate 104, the part of the off-line tooth 105 with higher hardness plays a supporting role, which is beneficial to the shaping and ejection of the shaped coil 100; the part of the off-line tooth 105 with lower hardness is in contact with the shaping tooth 102, so as to avoid scratches on the shaping tooth 102 and damage the coil.
[0051] Optionally, the hard tooth part and the soft tooth part of the off-line tooth 105 are in a split structure, and the soft tooth part is detachably connected with the off-line plate 104.
