A kind of fan-shaped silicon steel sheet, it includes the silicon steel sheet body of sector structure, the central angle of described silicon steel sheet body is 45 °, 60 °, 90 degree or 120 °, the inward flange of described silicon steel sheet body is concaved with multiple wire casing, the number of described wire casing is 6 ~ 25, and the outer surface of described silicon steel sheet body 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；

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:

The present invention includes the silicon steel sheet body of sector structure, during use, multiple fan-shaped silicon steel sheets is welded into loop configuration, will not waste lot of materials during this sector 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 fan-shaped silicon steel sheet that the present invention relates to and processing method thereof, silicon steel sheet body 1 including sector structure, the central angle of described silicon steel sheet body 1 is 45 °, 60 °, 90 degree or 120 °, the inward flange of described silicon steel sheet body 1 is concaved with multiple wire casing 2, the number of described wire casing 2 is 6 ~ 25, and the outer surface of described silicon steel sheet body 1 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；
