Compact strand die-drawing rolling production process and production equipment thereof

Abstract

The invention relates to a compact strand die-drawing rolling production process, and also relates to compact strand die-drawing rolling production equipment at the same time, wherein the compact strand die-drawing rolling production process comprises the steps of: carrying out stranding, die drawing compacting and rolling on raw materials of steel wires to be processed, and then deforming and eliminating the stress to obtain compact strands. In the compact strand production process of the invention, both the fixed integral die drawing method and the rolling method are adopted, the fixed integral die drawing method and the rolling method are integrally adopted in the process, the advantages of the fixed integral die drawing method and the rolling method can be fully exerted, meanwhile, the defects of the two methods are reduced, the compression coefficient of steel wire strands is improved, and the problems of unsmooth surface and expending strand looseness of the compact strand produced by the rolling method are solved.

Description

technical field [0001] The invention relates to a production process of compacted strand mold drawing and rolling, and also relates to a production equipment for producing compacted strands using the production process. Background technique [0002] At present, there are two main production methods of domestic compacted strand steel wire ropes: 1. The fixed integral mold drawing method, which uses the fixed integral mold to carry out plastic compression deformation on the strands to change the line contact strands into surface contact strands. The deformation and stress state of the steel wire is not ideal during the process of extrusion of the steel wire strand by the fixed integral die drawing method, and it is difficult to eliminate the internal stress of the steel wire and the strand. In addition, the deformation of the steel wire generates a lot of heat, and the compression coefficient does not reach the international advanced level; 2. Rolling method , the surface of t...

AI Technical Summary

Problems solved by technology

The deformation and stress state of the steel wire is not ideal during the process of extrusion of the steel wire strand by the fixed integral die drawing method, and it is difficult to eliminate the internal stress of the steel wire and the strand. In addition, the deformation of the steel wire generates a lot of heat, and the compression coefficient does not reach the international advanced level; 2. Rolling method , the surface of the compacted strand steel wire rope produced by the rolling method is not smooth, and the extension of the steel wire strand between the two sets of rollers is easy to cause loose strands. Difficult, the higher the rolling compression coefficient, the higher the requirements for the equipment
