[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] The present utility model provides a technical solution: As Figures 1-5As shown in the figure, in this embodiment, an insulating paper thermal flaring and shaping device for stator manufacturing includes: a heat dissipation mechanism 1. The heat dissipation mechanism 1 includes a base 11. On one side of the top of the base 11, there is a heat dissipation air box 12. On one side of the top of the base 11 near the heat dissipation air box 12, there are two slide rails 13. Heat dissipation slots 14 are opened on both sides of the heat dissipation air box 12. At the four corners of the bottom of the heat dissipation air box 12, there are pulleys 15. At the four corners of the bottom of the heat dissipation air box 12, there are fixed connections with pulleys 15. The bottom of the pulley 15 is slidably connected to the inner wall of the slide rail 13. On one side of the heat dissipation air box 12, there is a fixed connection with a ventilation net 16. On the side of the heat dissipation air box 12 away from the ventilation net 16, there is a dust-proof net 111. At both ends of the side of the dust-proof net 111 away from the ventilation net 16, there are bolts 112. Inside the heat dissipation air box 12, there are two support seats 110. On the top of both support seats 110, there are motors 19. The dust-proof net 111 is fixedly installed on the side of the heat dissipation air box 12 away from the ventilation net 16 through the bolts 112. The bottom of the support seat 110 is fixedly connected to the bottom side of the inner wall of the heat dissipation air box 12. The outside of the motor 19 is fixedly installed on the top of the support seat 110. On the output ends of both motors 19 on the side close to the ventilation net 16, there are fixed connections with heat dissipation fans 18. At the bottom of the side of the heat dissipation air box 12 close to the dust-proof net 111, there is a positioning mechanism 2. On the top of the base 11, there is a body mechanism 3.

[0025] In this embodiment, when the staff needs to perform thermal flaring and shaping processing on the insulating paper in the stator body 33, first, the stator body 33 on the positioning template 32 is transferred to the lower part of the thermal expansion plate 36 through the conveyor line 31. By starting the telescopic cylinder 35, the thermal expansion plate 36 is driven to descend to flare the insulating paper in the stator body 33. However, the thermal expansion plate 36 is prone to be affected by thermal expansion and thermal stress during long-term high-temperature operation, resulting in fatigue and damage of the material. Therefore, after the insulating paper processing is completed, it can be transferred away from the lower part of the thermal expansion plate 36 through the conveyor line 31. In a high-temperature environment, by starting the motor 19 to drive the heat dissipation fan 18 to rotate, the strong wind generated when the heat dissipation fan 18 rotates can cool the residual temperature emitted after the thermal expansion plate 36 finishes working. The wind direction is from the dust-proof net 111 entering and discharging through the ventilation net 16. Therefore, the dust-proof net 111 can block dust and impurities in the external environment, avoiding dust from entering the heat dissipation air box 12 and affecting the heat dissipation fan 18 and the motor 19. The staff can remove the dust-proof net 111 from the heat dissipation air box 12 through the bolts 112 for cleaning. The staff can take out the heat dissipation air box 12 from the base 11 through the pulleys 15 and the slide rails 13 to maintain the heat dissipation fan 18 and the motor 19 inside.

[0026] As Figures 2-5As shown in the figure, the positioning mechanism 2 includes a fixing plate 21. One side of the top of the fixing plate 21 is fixedly connected to one side of the bottom of the heat dissipation air box 12 close to the dust-proof net 111. The top of the fixing plate 21 is in contact with the bottom of the lever 22. Three movable columns 23 are arranged in the three card slots opened in the fixing plate 21. The top of the movable column 23 passes through the fixing plate 21 and is movably connected to the inside of the lever 22. The bottom of the movable column 23 passes through the inner ring of the spring 24 and is fixedly connected to the top of the positioning block 25. The bottom of the spring 24 is fixedly connected to the top of the positioning block 25. Three positioning grooves 26 are opened on the top of the base 11 near the two slide rails 13. The bottom of the positioning block 25 is clamped in the positioning groove 26.

[0027] In this embodiment, when the heat dissipation fan 18 dissipates heat from the heat expansion plate 36, it is necessary to fix the heat dissipation air box 12 on the base 11 to ensure its stable operation. Therefore, the staff can pull the lever 22. The lever 22 will rub and squeeze against the top of the fixing plate 21, and at the same time, it will drive the movable column 23 and the positioning block 25 to move upward. The spring 24 will also be squeezed and deformed due to the upward movement of the positioning block 25. Then the positioning block 25 will disengage from the positioning groove 26. Therefore, the heat dissipation air box 12 will be released from the limit on the base 11. When the staff moves the heat dissipation air box 12 to the specified position on the base 11 through the pulley 15 and the slide rail 13, release the lever 22, the spring 24 will lose the extrusion force and release the elastic force, and then will push the positioning block 25 into the positioning groove 26. Therefore, the heat dissipation air box 12 will be limited and fixed on the base 11.

[0028] The utility model provides an insulating paper heat expansion mouth shaping device for stator manufacturing, and the specific working principle is as follows:

[0029] During the process of the staff performing the heat-expanded mouth sizing process on the insulating paper in the stator body 33, first, the stator body 33 on the positioning template 32 is conveyed to the lower part of the heat expansion plate 36 through the conveyor line 31. Subsequently, the telescopic cylinder 35 is activated to drive the heat expansion plate 36 to descend, and the mouth of the insulating paper in the stator body 33 is processed. However, since the heat expansion plate 36 is used in a long-term high-temperature working environment, it is easily affected by thermal expansion and thermal stress. This kind of influence may lead to material fatigue and damage, thus affecting the normal operation of the heat expansion plate 36. Therefore, after the insulating paper processing is completed, it can be conveyed away from the lower part of the heat expansion plate 36 through the conveyor line 31 to avoid further thermal damage. In a high-temperature environment, in order to reduce the temperature of the heat expansion plate 36, the motor 19 can be activated to drive the cooling fan 18 to rotate. The strong wind generated when the cooling fan 18 rotates can effectively cool the residual temperature emitted after the heat expansion plate 36 finishes working. When the cooling fan 18 needs to dissipate heat from the heat expansion plate 36, in order to ensure its stable operation, the cooling air box 12 needs to be firmly fixed on the base 11. Therefore, the staff will pull the lever 22. When the lever 22 is pulled upward, it can drive the movable column 23 connected to it to move upward. When the movable column 23 moves upward, the positioning block 25 will also rise accordingly, which will cause the spring 24 connected to it to be compressed and deformed. Furthermore, the positioning block 25 will disengage from the positioning groove 26. Therefore, the cooling air box 12 will be released from the limit on the base 11. The staff will use the pulley 15 and the slide rail 13 to move the cooling air box 12 to the designated working position on the base 11. When the cooling air box 12 reaches the designated position, the staff will release the previously pressed lever 22. At this time, the previously compressed spring 24 will lose the external pressure, thereby releasing the elastic force it stores. This elastic force will push the positioning block 25 to move downward, making it snap back into the positioning groove 26 again. In this way, the cooling air box 12 is fixed on the base 11 again, ensuring that it will not move unnecessarily during operation.
