Background technology
Wind-driven generator by head, turn, empennage, blade form.Every part is the most critically important, and functions is: blade is used for accepting wind-force and transferring electric energy to by head；Empennage makes blade all the time facing to the direction the wind comes from thus obtains the wind energy of maximum；Turn the function that head can be made to rotate to realize empennage adjustment direction neatly；The rotor of head is permanent magnet, and stator winding cutting magnetic line produces electric energy.Traditional aerogenerator stator is to be stacked by the silicon steel sheet of multi-disc one cutting molding to press solidly, and due to silicon steel sheet loop configuration, wastes lot of materials during silicon steel sheet cutting molding.
It is to be gone out by common punch press by silicon steel sheet that traditional handicraft makes the method for generator unit stator, then by artificial superposition silicon steel sheet the most piecewise and insulation paper washer, more manually press-fit, the technique such as welding is made, last manual line, dipping lacquer, drying.It has the drawback that: 1, silicon steel sheet and insulation paper washer fit through superposition piecewise, and processing technique is loaded down with trivial details, complicated, inefficiency；2, by artificial, hand labor intensity is big, and workman costly, thus improves processing cost；3, artificial lamination, quality is relatively difficult to ensure card, and insulation effect is poor.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, it is provided that will not waste silicon steel sheet and the processing method thereof of lot of materials during a kind of cutting molding, processing method is simple, and work efficiency is high, and the labor intensity of workman is low, and total quality is good, and insulation effect is good.
The object of the present invention is achieved like this:
A kind of silicon steel sheet and processing method thereof, including silicon steel sheet body, described silicon steel sheet body is formed by the fan-shaped silicon steel sheet element solder at multiple identical central angles, and the inward flange of described silicon steel sheet unit is concaved with multiple wire casing；The outer surface of described silicon steel sheet unit is provided with high-permeability silicon-coated layer.
Described silicon steel sheet unit is 4 ~ 6；
Wire casing number on described silicon steel sheet unit is 10 ~ 20.
The processing method of the present invention comprises the following steps:
Step one, punching press: use punch press high speed stamping multi-station progressive die, manufacture the iron core of automatic laminating structure；
Step 2, lamination: on every silicon steel sheet, have the lamination slot being evenly distributed, lamination slot is concave hole along the top in blanking direction, bottom is convex hole, a piece of silicon steel sheet lamination slot spill position under upper a piece of silicon steel sheet lamination slot convex position being embedded exactly on punching blanking station, when upper a piece of by under the pressure of punch, with under a piece of reach to be fastenedly connected by self-assembling formation interference；
Step 3, injection molding nylon: be placed on full-automatic injection mold by the silicon steel sheet that superposition is good, with high-precision mold the position nylon material high voltage precision injection mo(u)lding needing to insulate, encase core portion nylon material to be insulated；
Step 4, around enamel-covered wire: the silicon steel sheet after injection molding nylon, on fully automatic wire winding machine use technique for coiling wind enamel-covered wire；
Step 5, drying: use vacuum technique to do vacuum paint dipping, drying and processing on Full-automatic infrared tunnel type baking line the silicon steel sheet winding enamel-covered wire.
Compared with prior art, the invention has the beneficial effects as follows:
Silicon steel sheet body of the present invention is formed by the fan-shaped silicon steel sheet element solder at multiple identical central angles so that will not waste lot of materials during this silicon steel sheet cutting molding；Processing method is simple, and work efficiency is high, and the labor intensity of workman is low, and total quality is good, and insulation effect is good.

Detailed description of the invention
See Fig. 1, a kind of silicon steel sheet that the present invention relates to and processing method thereof, including silicon steel sheet body 1, described silicon steel sheet body 1 is welded by the fan-shaped silicon steel sheet unit 2 at multiple identical central angles, the inward flange of described silicon steel sheet unit 2 is concaved with multiple wire casing 3, described silicon steel sheet unit 2 is 4 ~ 6, and wire casing 3 number on described silicon steel sheet unit 2 is 10 ~ 20, and the outer surface of described silicon steel sheet unit 2 is provided with high-permeability silicon-coated layer.
The processing method of the present invention comprises the following steps:
Step one, punching press: use punch press high speed stamping multi-station progressive die, manufacture the iron core of automatic laminating structure；
Step 2, lamination: on every silicon steel sheet, have the lamination slot being evenly distributed, lamination slot is concave hole along the top in blanking direction, bottom is convex hole, a piece of silicon steel sheet lamination slot spill position under upper a piece of silicon steel sheet lamination slot convex position being embedded exactly on punching blanking station, when upper a piece of by under the pressure of punch, with under a piece of reach to be fastenedly connected by self-assembling formation interference；
Step 3, injection molding nylon: be placed on full-automatic injection mold by the silicon steel sheet that superposition is good, with high-precision mold the position nylon material high voltage precision injection mo(u)lding needing to insulate, encase core portion nylon material to be insulated；
