Abstract

The invention provides a method for manufacturing an enameled rectangular copper wire for a wind driven generator by a die method and a device thereof. The method comprises the following steps: setting the fillet radius of a metering hole which takes a hollow prismoid shape and is arranged at the middle part of a die holder into 0.7-0.9mm, annealing the pressed rectangular copper wire after cleaning and antioxidation, continuously painting a polyurethane primer and a 200-grade polyamideimide finish paint by the dies, baking and cooling to the room temperature to obtain the finished product. In the invention, the dies are adopted to paint the composite-layer enamelled wire with high viscosity. The invention has the advantages of high surface finish of products, unified outer diameters, good high temperature resistance, good chemical resistance, higher tensile strength, higher flexibility, higher adhesiveness, higher softening breakdown resistance and the like, thus being suitable for the application requirements of the wind driven generator on high quality of surface finish, no paint blotches and great length of the enameled wire.

Description

technical field [0001] The invention belongs to a production method and special equipment for an electromagnetic insulated wire, in particular to a method and a device for manufacturing an enamelled copper flat wire for a wind power generator by a mold method. Background technique [0002] Enameled wire is a winding wire mainly used in motors, electrical appliances, instruments, transformers and other workplaces. Wind turbine coils have particularly strict requirements for enameled wires. The special requirements are: 1) Large length of enameled wires, production meters per shaft, heavy weight, about 180kg per shaft; 2) Sectional cut into 2 meters long, bent and fixed After the shape, it is lowered into the motor slot. It is required that the surface of each section of enameled wire has no defects, and the appearance is smooth; 3) The enameled wire is resistant to high temperature, and the temperature grade reaches Class C. [0003] At present, the enameled wire with compos...
