Parallel twisted wire rope pre-deforming device

Abstract

The invention provides a parallel twisted wire rope pre-deforming device. The pre-deforming device comprises a front plate, a middle plate and a back plate, and the front plate, the middle plate and the rear plate are all provided with a plurality of forks which are arranged uniformly in the circumferential direction and used for mounting outer-layer wire passing rollers, and a mounting groove formounting an inner-layer wire passing roller is formed between any two adjacent forks, and the inner-layer wire passing rollers are mounted in the mounting grooves inversely. According to the providedparallel twisted wire rope pre-deforming device, by forming the mounting grooves in the front plate, the middle plate and the rear plate and adopting an inversely mounted structure for the inner-layer wire passing rollers, cross arrangement of inner-layer strands and outer-layer strands is realized, the wire arrangement is compact, the internal stress and tension of the strands of each layer areuniform, and an obvious pre-deforming effect is achieved.

Description

technical field [0001] The invention relates to the technical field of steel wire rope processing equipment, in particular to a pre-deformer for parallel lay steel wire ropes. Background technique [0002] As is well known, steel wire rope is a commonly used lifting component. Because of its high strength, light weight, stable lifting, safety and reliability, it is widely used in material handling machinery for traction, lifting, tensioning and For carrying purposes. [0003] In the steel wire rope manufacturing process, pre-deformers are usually used to eliminate or reduce the stress of the steel wire strands and improve the anti-loosening performance of the steel wire rope. Most of the steel wire rope pre-deformers in the prior art are structurally designed with wire-passing rollers for the outer layer and wire-passing molds for the inner layer. Since the inner layer and the outer layer are distributed far away, the inner layer strands cannot be aligned with the outer lay...

AI Technical Summary

Problems solved by technology

Most of the steel wire rope pre-deformers in the prior art are structurally designed with wire-passing rollers for the outer layer and wire-passing molds for the inner layer. Since the inner layer and the outer layer are distributed far away, the inner layer strands cannot be aligned with the outer layer during twisting. The strands are deformed synchronously, resulting in a large difference in the helix angle of the inner and outer layers, which easily leads to quality problems such as looseness and uneven stress.
