DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] The directions mentioned below are Figure 1 The position of each component in the figure is taken as the reference.

[0027] like Figures 1 to 8 As shown, the device for forming the enameled wire of the stator of the generator of the present invention comprises a bottom plate 1, a bottom die 2, an upper die 3, an upper die plate 4, a supporting elastic member, a side die 5, a guide rail 7 and a push rod 8, the bottom die 2 comprises a first bottom die body 21 and a second bottom die body 22, the first bottom die body 21 is detachably arranged on the bottom plate 1, the second bottom die body 22 is connected and arranged above the first bottom die body 21, and an enameled wire placing portion 23 is formed on the upper surface of the first bottom die body 21;

[0028] The guide rail 7 is arranged on the bottom plate 1 in a horizontal front-to-back direction, the side mold 5 is matched and arranged on the guide rail 7, and the push rod 8 is connected to the front side of the side mold 5. Under the action of the push rod 8, the side mold 5 can move back and forth along the guide rail 7, and a first cavity is formed between the side mold 5 and the second lower mold body 22;

[0029] The supporting elastic member is vertically arranged, the upper end of the supporting elastic member is connected to the lower surface of the upper template 4, the lower end of the supporting elastic member is connected to the upper surface of the base plate 1, the upper template 4 is horizontally arranged, the upper mold 3 is detachably arranged on the lower surface of the upper mold 4, the upper mold 4 can drive the upper mold 3 to move up and down, and form a second cavity between the upper mold 3 and the first lower mold body 21.

[0030] When the generator stator enameled wire is formed, firstly, the lower mold 2, the upper mold 3 and the side mold 5 are designed and processed according to the forming shape, and the processed lower mold 2, the upper mold 3 and the side mold 5 are installed in the corresponding positions; then the enameled wire is placed on the enameled wire placement part 23, and the enameled wire and the guide rail 7 are made perpendicular to each other, and then the side mold 5 is moved along the guide rail 7 and attached to the second lower mold body 22 by the push rod 8, as shown in FIG. Figure 7As shown, at this time, the enameled wire is located between the side mold 5 and the second lower mold body 22 to form a first cavity, and the side mold 5 moves to complete the first molding process of the enameled wire (the front and rear direction of the enameled wire), so that the enameled wire is processed into a U shape; finally, the upper mold plate 4 drives the upper mold 3 to move downward and stick to the first lower mold body 21. At this time, the enameled wire is located between the upper mold 3 and the first lower mold body 21 to form a second cavity, and the upper mold 3 moves to complete the second molding process of the enameled wire (the up and down direction of the enameled wire), and the enameled wire is taken out after each component returns to its position, thereby completing the molding process of the enameled wire.

[0031] The side mold 5 is returned to its original position by the push rod 8, which moves the side mold 5 away from the second lower mold body 22. When the upper mold 3 moves downward, the supporting elastic member will be compressed. As long as the force that causes the upper mold 4 to move downward disappears, the upper mold 3 automatically returns to its original position under the action of the supporting elastic member. The force that causes the upper mold 4 to move downward can be provided by a cylinder or an oil cylinder.

[0032] Specifically, in order to facilitate the side mold 5 to move back and forth on the guide rail 7 and improve the stability of the side mold 5 when moving back and forth, Figure 5 , Figure 6 As shown, the cross-sectional shape of the guide rail 7 is a trapezoid that is narrow at the top and wide at the bottom. A slide groove 51 is provided at the bottom of the side mold 5. The cross-sectional shape of the slide groove 51 is a trapezoid that is wide at the top and narrow at the bottom that is adapted to the guide rail 7.

The fixing plate 9 is provided with a threaded hole, and the push rod 8 matches and passes through the threaded hole to be connected to the front side of the side mold 5. The push rod 8 drives the side mold 5 to move back and forth on the guide rail 7 through the threaded action, and the thread of the push rod 8 and the threaded hole prevents the push rod 8 from moving randomly, ensuring the normal first forming process of the enameled wire.

[0034] The supporting elastic member is preferably a spring, and the number of the supporting elastic members is multiple. The number of the supporting elastic members of the present invention is preferably two, and the two supporting elastic members are respectively arranged on the left and right sides of the lower mold 2.

The supporting elastic member is sleeved on the guide rod 10, and the guide rod 10 is vertically arranged on the bottom plate 1. A guide hole is provided on the upper mold plate 4, and the upper end of the guide rod 10 is arranged through the guide hole. In order to reduce the wear of the guide rod 10 on the guide hole and increase the service life, a guide sleeve 6 is provided between the guide rod 10 and the guide hole, that is, the guide sleeve 6 is provided in the guide hole, and the guide rod 10 is provided in the guide sleeve 6. In order to limit the stroke of the upper mold 3 moving up and down, a limit plate 11 is provided at the upper end of the guide rod 10.

[0035] In order to improve the stability of the entire device during the molding process, the bottom plate 1 is provided with a fixing groove 12, and the bottom plate 1 can be fixed on the ground through a fixing piece passing through the fixing groove 12.
