Stainless steel wire rope of (1+6+6/6) structure and used for lifting of automobile window

Abstract

The invention provides a stainless steel wire rope of a (1+6+6 / 6) structure and used for lifting of an automobile window. The stainless steel wire rope comprises a core wire steel wire with the diameter R1, six middle layer steel wires with the diameter R2 and twelve outer layer steel wires, wherein the six middle layer steel wires are evenly distributed around the core wire steel wire, and the outer layer steel wires are evenly distributed around the middle layer steel wires; six steel wires with the diameter R3 and six steel wires with the diameter R4 are evenly arrayed at intervals to formthe outer layer steel wires; the middle layer steel wires and the core wire steel wire are twisted in the same direction, and the twisting distance is 9-12 times the stranding diameter of the middle layer steel wires and the core wire steel wire; the outer layer steel wires and the middle layer steel wires are twisted in different directions, wherein the twisting distance is 6-10 times the rope diameter of the twisted steel wire rope; all the core wire steel wire, the middle layer steel wires and the outer layer steel wires are stainless steel wires. The stainless steel wire rope has excellentanti-fatigue performance, a high elastic elongation percentage and a high perpetual elongation percentage, the service life of the stainless steel wire rope is long, and the existing using demands for lifting of the automobile window can be met; the steel wire rope can be formed after being machined one time, and therefore production costs are lowered.

Description

technical field [0001] The invention relates to the technical field of steel wire rope design and manufacture, in particular to a stainless steel wire rope with a (1+6+6 / 6) structure used for lifting and lowering automobile windows. Background technique [0002] Steel wire ropes are used in many industrial fields. According to the material of the steel wire and the structure of the twisted rope, they also have different properties to meet different application requirements. For example, for steel wire ropes used for lifting and lowering automobile windows, it is necessary to take into account the high fatigue resistance and elongation performance of the steel wire ropes, including elastic elongation and permanent elongation, to ensure frequent lifting and smooth movement of the windows. In addition, the cost of the wire rope itself in the manufacturing process must also be considered. At present, most of the steel wire ropes used for lifting and lowering automobile windows ...

AI Technical Summary

Problems solved by technology

At present, most of the steel wire ropes used for lifting and lowering automobile windows are galvanized steel wire ropes, which need to be processed twice. In addition, the strength and ductility of galvanized steel wires generally cannot be balanced, and the ductility will be lower if the strength is high. When it is high, the strength will be relatively low; moreover, after the galvanized steel wire has been used for a long time, the galvanized layer on the surface will be corroded, which will cause the strength of the steel wire to drop sharply
