Embodiment

[0015] Embodiment: a kind of manufacture method of aluminum-copper alloy enameled wire, specifically comprises the following several steps:

[0016] (1) Pay-off: release the bare aluminum-copper alloy wire from the iron shaft evenly to provide raw materials and ensure the stability of painting. In the high-speed machine, rely on the combined wire drawing machine to release the wire; use nano-diamond composite coating wire drawing die , Aluminum-copper alloy special wire drawing oil is stretched into semi-finished aluminum-copper alloy wire by high-speed automatic wire drawing machine for many times;

[0017] (2) Annealing: adopt a special annealing process on the automatic enamelling machine, continuous annealing softens the bare aluminum copper wire, removes the internal stress during the stretching process, rearranges the molecular lattice, and enhances flexibility and conductivity;

[0018] (3) Cleaning: the annealed and softened conductor is cleaned with deionized...

Abstract

The invention provides a manufacturing method for an aluminum copper alloy enameled wire. The method concretely comprises the following steps: (1) wire releasing: an aluminum copper alloy bare wire is evenly released from an iron shaft, and wire releasing is performed via dependence on a combined wire drawing machine on a high-speed machine stand; (2) annealing: a special annealing process is adopted on a full-automatic enameling machine, and the bare aluminum copper wire is softened via continuous annealing; (3) cleaning: a conductor after annealing and softening is cleaned by adopting de-ionized water; (4) painting: a 200-order polyester imide insulating paint layer is coated on the surface of the aluminum copper alloy wire, and then 240-order polyamidoimide nanometer paint is coated on the polyester imide insulating paint layer; (5) baking: solvent in paint is evaporated via baking so that a paint base is solidified and a film is formed, and an insulating layer is formed; (6) and cooling: after the aluminum copper alloy wire is baked in a furnace, the aluminum copper alloy wire is cooled by cold air. The critical defect that a pure copper conductor is oxidized under the high-temperature state is overcome by the method so that the requirement of a high-heat-level enameled wire core is met.

Description

technical field [0001] The invention relates to the technical field of enameled wires, in particular to a method for manufacturing aluminum-copper alloy enameled wires. Background technique [0002] The current enameled wire uses pure copper core or pure aluminum core as the conductor. The pure copper conductor undergoes oxidation reaction at high temperature. The highest heat level of the copper core enameled wire can only reach 220. The pure aluminum conductor has small conductivity and large resistance. Tensile strength is weak. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for manufacturing an aluminum-copper alloy enameled wire. [0004] The object of the present invention is achieved by the following scheme: a method for manufacturing an aluminum-copper alloy enameled wire, specifically comprising the following steps: [0005] (1) Pay-off: release the bare aluminum-copper alloy wir...
