Embodiment 1

[0039] A method for preparing high-stretch micro-enameled round copper wire,

[0040] Its preparation steps are:

[0041] Step 1, unwinding

[0042] Use a pay-off machine to pay off the bare copper round wire;

[0043] A. The large-size and large-capacity spool adopts a radial rotary pay-off, the medium-sized bare copper round wire adopts an over-end or brush-type pay-off, and the fine-sized bare copper round wire adopts a brush-type or double-cone sleeve-type pay-off Wire device;

[0044] B. Control the tension of the bare copper round wire during the unwinding process. The maximum non-extensible tension of the bare copper round wire is about 15kg / mm² at room temperature, and about 7kg / mm² at 400°C, and about 7kg / mm² at 460°C. The maximum non-stretching tension is 4kg / mm², and the maximum non-stretching tension is 2kg / mm² at 500°C. The tension of the bare copper round wire should be significantly smaller than the non-stretching tension, which is controlled at about 50%. Th...

Abstract

The invention relates to the machining field of production equipment of an enamelled wire, particularly to a preparation method of a high-stretching micro-thin enamelled round copper wire. The preparation method comprises the steps of paying off, annealing, paint coating, baking, cooling and taking up. The bare round copper wire adopts monocrystal copper, and the copper material drawn by a monocrystal continuous casting technology is formed by only one crystalline grain, so that ultra-high mechanical machining performance, electrochemical characteristics and high-stretching performance are achieved, so the problems of thinning caused by drawing, line breaking, paint falling off ( cracks and slits formed in a paint film), pin hole generation, low resistance balance rate, unqualified information transmission correctness and the like can be overcome; and in addition, "waste materials can be recycled for use" through secondary catalysis and combustion, so that environment protection, energy conservation, safety and convenience can be realized.

Description

technical field [0001] The invention relates to the field of enameled wire production equipment processing, in particular to a method for preparing high-stretch fine enameled round copper wire. Background technique [0002] Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. Enameled wire has four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. However, it is not easy to produce products that meet both requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enameled wires vary. Especially in the fully automatic high-speed winding process, despite the cooperation of the constant tension wire defense system, ordinary enameled wires are ...
