Problems solved by technology

[0002] Today, with the rapid development of national defense and electronic industries, enameled wires have become an indispensable wire in military equipment such as household appliances, radars, and computers, as well as civilian electrical and electronic products. Traditional enameled wires are generally enameled wires with a circular cross-section. Copper wire, the traditional enamelled round copper wire has the disadvantage of large gaps between the enameled wires during the coil winding process, which leads to problems such as large volume and heavy quality of the corresponding coils, which cannot adapt to today's The use of national defense and civilian electrical equipment requires

Embodiment Construction

[0012] Embodiment of the present invention: the aluminum wire is made into a thin and flat aluminum wire by extrusion and stretching, and the cost of the aluminum wire can be saved by nearly 60% compared with the copper wire, and the stretching lubricating fluid is used when stretching, The drawing lubricating fluid is a special wire drawing lubricating liquid for aluminum wires. The special wire drawing lubricating liquid for aluminum wires is composed of 78-92 parts by mass of rapeseed oil, 3-7 parts of kerosene, 9-10 parts of diesel oil, and 0.1-1 part of phenol. . Clean the thin and flat aluminum wire 1 after stretching with an alkaline cleaning solution to remove oil stains on the surface of the thin and flat aluminum wire. The pH value of the alkaline cleaning solution used is between 8 and 9, and then pass The organic solution removes the oxide layer on the surface of the thin and flat aluminum wire 1. The organic solution used is a cleaning agent for bare aluminum wire...

Abstract

This invention discloses a manufacturing method for enamel insulated Al flat wires, which manufactures an Al lead with round section shape to an Al flat lead with rectangular section by extrusion and drawing and uses drawing lubricant when drawing, cleans the flat Al lead in alkali solution to remove oil dirt on the surface then to remove the oxidation layer on the surface with organic solution then coats the lead with enamel paint to finish the process.

Description

technical field [0001] The invention relates to a method for manufacturing an enameled wire, in particular to a method for manufacturing an enameled aluminum flat wire. Background technique [0002] Today, with the rapid development of national defense and electronic industries, enameled wires have become an indispensable wire in military equipment such as household appliances, radars, and computers, as well as civilian electrical and electronic products. Traditional enameled wires are generally enameled wires with a circular cross-section. Copper wire, the traditional enamelled round copper wire has the disadvantage of large gaps between the enameled wires during the coil winding process, which leads to problems such as large volume and heavy quality of the corresponding coils, which cannot adapt to today's The use of national defense and civilian electrical equipment needs. Contents of the invention [0003] The object of the present invention is to provide a kind of ma...
