A Pre-deformer for Parallel Lay Steel Wire Rope

Abstract

The invention provides a pre-deformer for parallel lay steel wire ropes, which includes a front disc, a middle disc and a rear disc. The front disc, the middle disc and the rear disc are all provided with several forks which are used to install the outer layer passing rollers and are evenly distributed in the circumferential direction. Any two adjacent forks are provided with installation grooves for installing the inner layer wire passing rollers, and the inner layer wire passing rollers are installed upside down in the installation grooves. The parallel lay steel wire rope pre-deformer provided by this application realizes the cross arrangement of the inner strands and the outer strands by setting installation grooves on the front disc, middle disc and rear disc, and the inner layer wire passing roller adopts an inverted structure , the wiring is compact, the internal stress and tension of each layer of strands are uniform, and it has a significant pre-deformation effect.

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.
