The processing method of the present invention comprises the following steps:
Step one, punching press: adopt 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 under the upper a piece of pressure being subject to 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 insulation, encase the core portion nylon material to insulate；
Step 4, around enamel-covered wire: the silicon steel sheet after injection molding nylon, on fully automatic wire winding machine adopt technique for coiling wind enamel-covered wire；
Step 5, drying: the silicon steel sheet winding enamel-covered wire is toasted employing vacuum technique on line at Full-automatic infrared tunnel type and does vacuum paint dipping, drying and processing.
Compared with prior art, the invention has the beneficial effects as follows:
Wire casing of the present invention is half opening rectangular channel, make this square motor stator fixed effect when coil is wound around better, it is provided with perforation centered by stalloy and corner is the square structure of fillet, substantial amounts of waste is not resulted in when producing cutting, processing method is simple, and work efficiency is high, and the labor intensity of workman is low, total quality is good, and insulation effect is good.
