[0002] The current global market for extremely fine steel wire rope, i.e. diameter ≤0.1mm, shows explosive growth in demand for steel wire rope that meets micron-level requirements in some application scenarios, with the core driving force coming from technological innovation in the precision of high-end manufacturing, the minimally invasive nature of medical technology and the cross-border integration of emerging fields. The domestic market has formed a scale advantage in the fields of new energy and consumer electronics, and products such as nickel-plated steel wire for power battery tab welding and stainless steel micro-wire for folding screen hinges have achieved localization substitution, but there are still significant technical bottlenecks in high-end fields such as medicine and aerospace. The fatigue life of medical ultra-fine steel wire rope is significantly different from that of imported products, and the breakage rate and surface treatment uniformity of micron-level processing technology lag behind international standards.

[0003] Problems with existing technology: Traditional pay-off devices for pipe winches use mechanical friction plates, springs or gravity counterweights to control tension, which has the following drawbacks: mechanical friction wears out easily, resulting in large tension fluctuations that cannot meet the high-precision winding requirements of extremely fine steel wire rope; high-speed pay-off has large inertial impact, resulting in a high breakage rate; the structure is complex and requires frequent maintenance, making it difficult to adapt to continuous production environments. Existing magnetic damping technology is mainly used in the textile and cable industries, but it is not designed to adapt to the rigidity and high tensile strength of steel wire rope. There is a lack of a tension control system specifically designed for extremely fine steel wire rope pipe winches to achieve micron-level tension stability. Utility model content
