Embodiment Construction

[0011] A kind of multilayer strand steel wire rope manufacturing method of the present invention is described in further detail below: the multilayer strand steel wire rope manufacture method of the present invention comprises following implementation steps:

[0012] (1) The inner layer rope is twisted, and the rope strands are not pre-deformed during production. The inner layer rope must be tied firmly during production to ensure that the inner layer rope is not broken and the tension of the rope strands is guaranteed;

[0013] (2) The outer strands are twisted, and 45-50% of the pre-deformation is carried out during production, so that the outer strands are strengthened to meet the torque balance with the inner strands;

[0014] (3) Steel wire rope twisting, which consists of an inner layer rope and multiple outer layer strands. When twisting, the inner layer rope needs to be tightened. The number of turns for tightening is 4-5 turns. As the production progresses , the upper...

Abstract

Provided is a multilayer strand steel wire manufacturing method. When an inner layer rope is twisted, a rope strand is not deformed in advance, and when an outer layer strand is twisted, the strand is deformed by 45-50% in advance, so the outer layer rope strand is tightly twisted, and the torque balance of the outer layer rope strand and an inner layer rope is achieved; when a steel wire rope is twisted, the inner layer rope is tightly twisted, and the number of twisting circles is 4-5; along with production, twisting is gradually distributed in the length range of the whole steel wire rope, the more twisting is conducted, the faster the discharged steel wire rope enters the inner layer and outer layer lay length balanced state, and finally the inner layer strand and the outer layer strand of the steel wire rope reach the torque balance; finally, the twisted steel wire rope is compacted by a roller, and the compression rate is 14%. In the use process, the steel wire rope can not be easily untwisted and is long in service life.

Description

technical field [0001] The invention relates to a method for manufacturing a multi-layer strand steel wire rope, belonging to the technical field of metal cable processing. Background technique [0002] During the use of the existing multi-layer steel wire rope, when running on the pulley, the steel wire rope rotates while running. In each cycle, the number of turns of the steel wire rope during the up and down process is different. It only came back 2 times, and without a cycle, the steel wire rope accumulated a circle on it, causing the inner and outer layers of the upper end of the wire rope to separate from each other, and the inner layer was stretched by force, and the excess length of the rope core was easy to protrude when unloading. Out of the outer strands, the phenomenon of wire rope breaking occurs, resulting in quality accidents. Due to the high requirement of the breaking force, the use of the wire rope is narrow and the bending angle is relatively sharp, the p...
