Copper-clad aluminum varnished wire processing technique

Abstract

The invention discloses a copper-clad aluminum varnished wire processing technique which comprises the following steps: (a), drawing a copper-clad aluminum varnished wire core for 4-6 times; (b), painting the drawn wire core for 10-13 times, wherein each painting comprises the following steps: (b1), lacquering the wire core, (b2), placing the lacquered wire core into an annealing furnace for annealing, and (b3), placing the annealed wire core into a drying oven for drying; (c), winding up, wherein the speed of winding up is 5 plus or minus 1 m / minute; and (d), unwinding and packaging. The copper-clad aluminum varnished wire processing technique is the combination of copper and aluminum metallurgy, obtains a certain diameter of copper clad aluminum varnished wire with the required electrical property and is endowed with the required mechanical property through a heat treatment method, thereby providing a material capable of replacing an enameled copper wire for a large-scale transformer; and through replacing the enameled copper wire with the copper-clad aluminum varnished wire, the consumption of copper resources is greatly reduced, the production cost is saved, and the performance is stable.

Description

technical field [0001] The invention relates to a heating device, in particular to a copper-clad aluminum enameled wire processing technology for enameled wire production. Background technique [0002] Enameled wire is the most representative product among electronic wires. Enameled wire is a main variety of winding wire, including the core wire and the paint layer coated on the outside of the core wire. After the bare wire is annealed and softened, it is painted and baked many times. It has four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. Copper-clad aluminum enameled wire is a new type of electromagnetic wire that uses copper-clad aluminum material as the inner conductor. Its characteristics are between copper and aluminum, combining the advantages of copper's excellent conductivity and aluminum's light weight. Micro motor rotor coils and various electromagnetic wires are widely used. [0003] With the rapi...
