A kind of special-shaped steel wire production method

Abstract

The invention relates to a special-shaped steel wire production method, which is a continuous overall die-drawing production method for special-shaped steel wires. It uses a rotating mold box to position the special-shaped mold to ensure that the special-shaped mold has the same outlet mode, and passes the special-shaped surface of the steel wire between the upper and lower passes. Adjust the direction of the mold by itself to ensure the accuracy of the shape and size of the steel wire to meet the changes in the size and compression rate of the steel wire during the production process. The gripper of the subsequent reel is polished to ensure that the size of the subsequent special-shaped surface of the steel wire is getting smaller and smaller. The performance and size of the steel wire can meet the plastic deformation required by the gripper. The method improves product quality, reduces production procedures, shortens production cycle, improves production efficiency and reduces production cost.

Description

technical field [0001] The invention relates to a production method of a special-shaped steel wire, in particular to a continuous die-drawing production method of a special-shaped steel wire, which belongs to the technical field of metal product processing. Background technique [0002] The production methods of special-shaped steel wire usually adopt roll drawing, rolling, drawing-rolling combination, etc. The above production methods have their own advantages and disadvantages, but they all have irregular shapes, large fluctuations in dimensional tolerances, poor surface quality, and poor passability. equal quality issues. For example, the current special-shaped steel wire used in the production of sealed steel wire rope adopts cyclic heat treatment and rolling production method. The special-shaped steel wire produced by this method has low dimensional accuracy, poor performance of the steel wire, and many production cycles, resulting in loose buckle between the steel wir...

AI Technical Summary

Problems solved by technology

The special-shaped steel wire produced by this method has low dimensional accuracy, poor performance of the steel wire, and many production cycles, resulting in loose buckle between the steel wires during the twisting process of the sealing wire rope, rough surface and low strength, which affects the sealing wire rope. The performance of the sealing wire rope is long, and the cost is increased at the same time.
