Problems solved by technology

[0002] In the production of existing enamelled flat wires, copper conductors are often rolled first and then coated with a layer of insulating varnish on the surface. The enameled flat wires produced in this way often have low strength, and are prone to bubbling and resistance to heat during use. not hot

Embodiment Construction

[0016] A high-performance enamelled flat wire processing technology, which comprises the following steps:

[0017] In step a, the copper conductor is flattened first, and the edge is rolled by the vertical roller, and then the copper conductor is drawn through the mold, so as to ensure the uniformity of the size of the copper conductor, improve the performance of the copper conductor, and reduce the defects of the copper conductor;

[0018] In step b, perform power frequency induction recrystallization annealing on the copper conductor obtained in step a. The annealing temperature is greater than or equal to 380 degrees Celsius to improve the grain size, eliminate internal stress, and soften the metal. At the same time, the length of the power frequency induction annealing furnace is relatively short. Generally 2m compared to the 18m ordinary annealing furnace, the wire is not easy to touch the furnace wall and cause scratches; then ultrasonic cleaning and drying, the cleaning ...

Abstract

The invention provides a processing technology of a high-performance enameled flat wire. The high-performance enameled flat wire is good in strength, and resistant to heat resistance. The method comprises the following steps: step a, flattening a copper conductor, edging the flattened copper conductor through a vertical roller, and drawing the copper conductor through a die; b, performing annealing treatment on the copper conductor obtained in the step a, and then performing ultrasonic cleaning and drying; and c, coating the surface of the copper conductor obtained through treatment in the step b with polyimide, wherein the coating frequency is larger than or equal to 18 times, the coating thickness each time is larger than or equal to 0.015 mm, and the copper conductor is baked once everyother 1-5 times.

Description

technical field [0001] The invention relates to the technical field of enamelled flat wires, in particular to a high-performance enameled flat wire processing technology. Background technique [0002] In the production of existing enamelled flat wires, copper conductors are often rolled first and then coated with a layer of insulating varnish on the surface. The enameled flat wires produced in this way often have low strength, and are prone to bubbling and resistance to heat during use. The heat is not good. Contents of the invention [0003] In view of the above problems, the present invention provides a high-performance enamelled flat wire processing technology, which has good strength, heat resistance and other properties. [0004] Its technical solution is as follows: a high-performance enamelled flat wire processing technology, characterized in that it includes the following steps: [0005] Step a, flattening the copper conductor first, and rolling the edge through ...
