Stranded wire wrapping process with high production efficiency

Abstract

The invention discloses a stranded wire wrapping process with high production efficiency. An empty rubber shaft, a stranded wire and a silk wire required for producing the silk-covered wire are determined according to a production task; a wrapping head and a wrapping pendulum with corresponding specifications are prepared on a silk wrapping machine according to the finished outer diameter size ofthe stranded wire, and preproduction preparation is made; then, manual operation is combined in the production process of the silk wrapping machine, the structure installation mode and the position ofthe silk wrapping machine are adjusted, the tension of unwinding and winding and the winding displacement of winding are properly adjusted, so that the wire wrapping machine can stably complete stranded wire wrapping work and finally perform unwinding work. Through the stranded wire wrapping process, the work efficiency of stranded wire wrapping can be improved, silk-covered wires can be accurately and quickly produced, and the operation process of the wire wrapping machine can be standardized.

Description

technical field [0001] The invention specifically relates to a stranded wire wrapping process with high production efficiency. Background technique [0002] Silk-coated enameled stranded wire is a high-frequency winding wire with double insulation layers, which can be widely used in transformers or inductance coils in high-frequency and high-voltage working environments, such as antenna inductors, LCD TVs, LED energy-saving lamps, etc. Since the appearance of wire-covered wire products in the 1980s, its market size and application fields have been expanding year by year. Especially in recent years, the demand for wire-covered wires for high-power electrical equipment has gradually become stronger.

AI Technical Summary

Problems solved by technology

[0003] The second insulating layer of the existing silk-covered wire, that is, the silk covering is made by the wrapping process, the technology is relatively mature, and the process is relatively easy to realize, and the thickness of the silk layer can be easily adjusted by changing the twist; The disadvantage of silk technology is that it is difficult to take into account the softness and silk layer adhesion of the silk-covered wire. When wrapping, the wire tension is large and the silk layer adhesion is good, but the wire is too hard, which brings disadvantages to coil winding; the wire tension is small, The wire is soft and feels good, but it is easy to fall off and the adhesion is not good, so there is a risk of inter-turn or inter-layer short circuit in the transformer

In addition, the wire tension control accuracy of the wrapping process is not high, and there will be a large deviation between the actual product performance and the design requirements

The above-mentioned contradictions are particularly obvious on wire-covered wires with larger wire diameters, which further restricts the promotion of wire-covered wires in high-power electrical products.
