Problems solved by technology

This production process consumes a lot of energy in the production process. At the same time, the distance between the two furnaces with a large temperature difference is too close, which also adds a lot of difficulty to the control of product quality.

Embodiment Construction

[0025] The production method of the self-adhesive magnet wire of the present invention will be described in conjunction with the accompanying drawings and examples.

[0026] In order to produce self-adhesive magnet wires for compressor motors, a long-term exploration was carried out in the selection of raw materials and production processes. After multiple rounds of PDCA cycle screening, the best manufacturing process was selected.

[0027] The production method of self-adhesive magnet wire of the present invention, this method comprises the following steps:

[0028] 1) Selection of raw materials:

[0029] The main raw material of the self-adhesive magnet wire is copper rod, the copper rod uses low-oxygen copper with a purity of more than 99%, and the insulating varnish coated uses imported polyesterimide (PEI) paint and polyamideimide (PAI) Paint, self-adhesive insulating paint;

[0030] 2) Production process of self-adhesive magnet wire:

[0031] ①Pull

[0032] Firstly, ...

Abstract

The invention provides a production method of a self-adhesive electromagnetic wire. The production method comprises the following steps of: selection of raw materials, production process of the self-adhesive electromagnetic wire: (1) drawing; (2) annealing; (3) painting; (4) detection of the curing degree; and (5) detection. The production method provided by the invention has the effect that compared with the conventional self-adhesive electromagnetic wire, the self-adhesive electromagnetic wire breaks through the limitation of the traditional dual-hearth production process and can use a single-hearth mode for production on a high-speed vertical type enamelling machine. The production method has the advantages that under the premise of ensuring the quality of a product, the production efficiency is improved and the production cost is effectively reduced.

Description

technical field [0001] The invention relates to a production method of self-adhesive magnet wire suitable for self-adhesive air-conditioning compressors. Background technique [0002] In order to actively respond to the national energy-saving and emission-reduction policies, major air-conditioning companies have adjusted to seek improvements in raw materials and production processes. Among them, the use of self-adhesive magnetic wires to replace traditional magnetic wires is also one of the methods widely adopted by major compressor manufacturers. In the traditional winding manufacturing process, the stator and rotor must go through the impregnation process after being wound and shaped. This process has brought great cost pressure to the compressor manufacturer. At the same time, a large amount of irritating gas will be generated during the impregnation process. The final impregnated product also has uneven coating of impregnated varnish, which affects the overall quality o...
