Production technology of enamelled wire

Abstract

The invention relates to a production technology of an enamelled wire. The production technology sequentially comprises a blank purchasing step, a blank checking step, a wire drawing step, an annealing step, an enamelling step and a take-up step, wherein a blank is stretched at the speed of 300m / min in the wire drawing step. According to the production technology of the enamelled wire, wire rods with various specifications for copper wires and copper-clad aluminium enamelled wires can be produced; the production technology is simple; and the production cost is relatively low, so that the enamelled wire is relatively low in price; and the tensile strength can be improved to a certain extent.

Description

technical field [0001] The invention relates to a production process of an enameled wire. Background technique [0002] At present, manufacturers producing enameled wires consume a lot of manpower investment, electricity investment, and plant area investment, and at the same time, they are not very good at meeting the tensile strength requirements of the electromagnetic wire and electroacoustic industries. The traditional enameled wire production process steps are: wire drawing, take-up, pay-off, annealing, enamelling and take-up. When this process draws the wire to the reel, it is very easy to deform and twist the wire. This phenomenon is especially easy to appear in copper-clad aluminum wires with a value of about 0.15. The deformation and twist of the wire will seriously directly affect the surface finish of the pay-off and the finished enamelled package, and then affect the product quality of the electromagnetic wire application range of the motor and the electroacoust...
