A kind of processing technology of anti-rotation steel wire rope

Abstract

The invention discloses a processing technology of an anti-rotation steel wire rope, in particular relates to a processing technology of an 8-strand anti-rotation steel wire rope, belonging to the field of steel wire rope processing, including: S1. wire drawing; S2. twisting strands; S3. making central strands; S4. Strand Winding: Wind the prepared central strand onto the winding wheel; S5. Rope formation: Connect the winding wheel to the rope inlet side of the rope forming machine, and put the finished rope side strands into the rope forming machine, and drive the winding The wire wheel rotates around its axis to feed the rope, and at the same time drives the winding wheel to rotate in a vertical plane perpendicular to its axis, and the rotation direction is consistent with the twist direction of the central strand, so that the side strands of the rope in the rope machine are The outer side of the center strand is twisted, and its direction of rotation is opposite to that of the center strand. The present invention reduces the torsion force of the outer layer of the combined rope by increasing the lay length of the steel wire rope and the diameter of the central strand, and at the same time designs all the side strands and the central strand to be opposite to the twist direction of the steel wire rope, so that the internal and external rotational forces cancel each other out, thereby ensuring that the 8-strand steel wire rope has Softness, wear resistance and anti-rotation properties.

Description

technical field [0001] The invention relates to the field of steel wire rope processing, in particular to a processing technology of an anti-rotation steel wire rope. Background technique [0002] Steel wire ropes are widely used in chemical, coal, metallurgy, petroleum, lifting and other industries. They have the advantages of good fatigue resistance, high temperature resistance, and durability. Different industry needs have different requirements for the flexibility of steel wire ropes. Moreover, in some In high-altitude operations, there is a high requirement for the performance of the wire rope not to rotate. The existing lifting anti-rotation wire ropes are mainly (35w*7, 35k*7, 18*7, 19*7, 6*26ws, 4*39s) etc. The series is widely used, 35w*7.35k*7.18*7.19*7. It has anti-rotation characteristics, good flexibility but many strands, small strands, not wear-resistant, easy to break; 6*26ws has no anti-rotation characteristics , the rope will rotate, but it is wear-resista...
