Detailed Description
The invention will be further described with reference to the drawings and examples.
As shown in the figure, the insulating paper forming device for the flat copper wire stator comprises a base 7, an arc groove 1, an L-shaped groove 2 and a square groove 3, wherein an inclined groove is formed in the base 7 and is an upward groove inclined along the direction of the square groove 3, the inclined groove is separated into the arc groove 1 and the L-shaped groove 2 by a lug 5 on the side wall of the inclined groove, the arc groove 1 and the L-shaped groove 2 are mainly used for placing insulating paper, the arc groove 1 is positioned above the L-shaped groove 2, and the arc groove 1 is positioned above the L-shaped groove 2 to match the shapes of the two grooves so as to form the insulating paper. The other end of the inclined groove is provided with a square groove 3, the widths of the square groove 3 and the inclined groove are equal, so that insulation paper is convenient to be further molded from the inclined groove to the square groove 3, and if the width of the square groove is too large, the preliminarily molded insulation paper cannot form a shape with higher matching degree with a square hole in the square groove 3; if the width of the square groove 3 is smaller, the preliminarily formed insulating paper can form a shape with a higher height and a narrower width in the square groove 3, and the insulating paper is not beneficial to matching with the square hole. The L-shaped groove 2 is a groove which is inclined upwards along the direction of the square groove and is intersected with the square groove 3 at the intersection line 6 to form a through groove, the L-shaped groove 2 is the through groove, so that the transition of the preliminarily formed insulating paper into the square groove 3 is ensured, the intersection line 6 is formed with the square groove 3, and the shape of the insulating paper can be restrained when the insulating paper is in transition, so that the insulating paper is changed into a rectangle from an arc shape 'back'. The arc-shaped groove 1 is also a groove which is inclined upwards along the direction of the square groove and is intersected with the upper surface of the base 7, and an intersection line formed by the arc-shaped groove 1 and the upper surface of the base 7 also has the function of restraining the shape of the insulating paper.
In order to facilitate the installation and the cooperation of the device and other devices, a connecting device can be arranged on the base 7, such as a hook or a connecting rod is arranged on the base 7, in order to simplify the structure, the trouble possibly caused by large volume during the installation of the device is reduced, preferably, positioning holes 4 are also arranged on two sides of the square groove 3, corresponding holes can be arranged on other devices, and then bolts are inserted into the positioning holes 4 to realize the cooperation with other devices, or protrusions matched with the positioning holes 4 are directly arranged on other devices.
Because the slots distributed in the stator core of the efficient generator with the flat copper wire are square holes, and the insulating paper is inserted into the square holes after being molded, the insulating paper molded by the insulating paper molding device for the flat copper wire stator is also square. The insulating paper is bent into a 'back' shape in an arc shape mainly through the arc-shaped groove 1 and the 'L-shaped groove 2', so that the upper surface and the lower surface of the insulating paper in the arc shape are required to be kept parallel, and the bottoms of the arc-shaped groove 1 and the L-shaped groove 2 are mutually parallel so as to ensure that the 'back' insulating paper is parallel on the upper surface and the lower surface in the forming process.
Because the one side after insulating paper becomes "back" type is located L type groove 2 bottom, and insulating paper after the shaping need follow L type groove 2 and arc inslot 3 of sliding out in the groove 1, in order to guarantee sufficient shaping degree, L type groove need have certain length, in order to be convenient for the insulating paper after the shaping to pass through smoothly in the square groove 3 simultaneously, preferably, the length of L type groove 2 is greater than the length of lug 5, such setting has also guaranteed that square groove 3 and the adjacent one end of lug 5 keep the parallel and level can for whole structure is simpler, and the processing degree of difficulty is little.
The working process of the device is as follows: one end of the insulating paper is placed at the bottom of the L-shaped groove 2, the insulating paper is abutted against the groove wall, then the insulating paper is bent to be attached to the arc-shaped groove 1, the other end of the insulating paper is aligned with the edge of the convex block 5, at the moment, the insulating paper forms an arc-shaped return shape, when the insulating paper transits into the square groove 3, the L-shaped groove 2 and the square groove 3 form an intersecting line 6, and the intersecting line formed by the arc-shaped groove 1 and the upper surface of the base 7 is matched with the shape of the square groove 3, the insulating paper which is formed preliminarily is restrained into a rectangular shape with higher matching degree with the square hole, the insulating paper comes out of the square groove 3 to complete the whole forming process, the return insulating paper which meets the technological requirements is formed, and the parameters of the square groove 3 are matched with those of the square hole, so that the insulating paper after forming can be inserted into the square hole smoothly.
