Production device for compacted strand steel wire rope and production method of production device

Abstract

The invention discloses a production device for a compacted strand steel wire rope and a production method of the production device. The production device comprises a stranding device, an oil injection device, a line pressing mold, a first deformation mechanism, a second deformation mechanism and a take-up device, all of which are sequentially arranged. The oil injection device is arranged on a closing opening of the stranding device. The first deformation mechanism comprises multiple roller sets arranged in the advancing direction of the steel wire rope. The second deformation mechanism comprises multiple pairs of second deformation pulley sets and second traction wheels arranged in the advancing direction of the steel wire rope. Compared with the prior art, the roller sets are subjected to compressive deformation gradually, and steel wire rope strands are subjected to plastic deformation. The steel wire rope is subjected to repeated bending deformation through the pairs of second deformation pulley sets, and the purpose of eliminating stress is achieved accordingly. The production process is simple and convenient, all layers of the steel wire rope strands fully deform, the effective area of the steel wire rope is increased, the breaking force of the steel wire rope is improved by 50%, damage to the mechanical performance of the steel wire rope strands in the plastic deformation process is low, the bearing loads of the steel wire rope are guaranteed, and the service life of the steel wire rope is prolonged.

Description

technical field [0001] The invention belongs to the technical field of a steel wire rope production device, and in particular relates to a production device and a production method of a compacted strand steel wire rope. Background technique [0002] Steel wire ropes with compacted strand wire ropes such as 6×K31WS, 6×K36WS, 18×K7, 35W×K7 and other structures have higher wear resistance, extrusion resistance, and breaking tension than ordinary steel wire ropes. , so it is widely used. At present, the production methods of all production enterprises include: integral die drawing method, forging method, rolling method, special-shaped steel wire twisting method. The die-drawing method is axial force, which deforms the steel wire on the surface, and its compression deformation is small; the forging method is radially stressed, and the deformation is large, but the mechanical properties of the internal steel wire are damaged; the rolling method is also subjected to radial pressur...

AI Technical Summary

Problems solved by technology

The die-drawing method is axial force, which deforms the steel wire on the surface, and its compression deformation is small; the forging method is radially stressed, and the deformation is large, but the mechanical properties of the internal steel wire are damaged; the rolling method is also subjected to radial pressure and deformation. Although the quantity is large, the surface steel wire is prone to "ears", which seriously affects the surface quality and mechanical properties of the steel wire; the special-shaped steel wire twisting method is difficult to produce wire drawing and twisted strands, and the production efficiency is low, so it is rarely used
