Abstract
The invention relates to a fan-shaped silicon steel sheet and a processing method thereof. The fan-shaped silicon steel sheet is characterized in that the fan-shaped silicon steel sheet includes fan-shaped silicon steel sheet bodies (1); the central angles of the silicon steel sheet bodies (1) is 45 degrees, 60 degrees, 90 degrees or 120 degrees; a plurality of wire slots (3) are formed in the inner edge of each silicon steel sheet in an inward concave manner; the number of the wire slots (2) is 6 to 25; the outer surface of the silicon steel sheet (1) is provided with a high magnetic conduction silicon coating layer; the processing method includes stamping, laminating, nylon injection, enameled wire coiling and drying. According to the invention, the fan-shaped silicon steel sheet bodies are welded into an annular structure by adopting the processing method for use. Waste of a large amount of material during the silicon sheet cutting formation process is avoided. Besides, the silicon steel sheet is simple in processing method, high in working efficiency, low in labor strength, good in integral quality and good in insulation effect.
Description
technical field [0001] The invention relates to a fan-shaped silicon steel sheet and a processing method thereof, belonging to the field of electromechanical technology. Background technique [0002] Silicon steel sheets are mainly used to make iron cores for various transformers, motors and generators. , the traditional silicon steel sheets used to make iron cores are all ring structures, and a large amount of material is wasted in the cutting and forming process of silicon steel sheets during production. [0003] The traditional method of manufacturing generator stators is to punch silicon steel sheets through ordinary punching machines, then manually stack silicon steel sheets and insulating paper pads one by one, and then manually press-fit and weld them to make them, and finally manually lay the wires, soak them Paint, dry. Its disadvantages are: 1. The assembly of silicon steel sheets and insulating paper pads is superimposed one by one, the processing technology is ...
