Problems solved by technology

[0005] The present invention can solve the problem that when the existing equipment twists the steel wire rope, the positioning effect of the steel wire rope is poor and the positioning is inaccurate. Straightening leads to the twisting effect of the steel wire rope. At the same time, when the existing equipment twists the steel wire rope, it cannot compress and twist the steel wire rope, which makes the steel wire rope easy to loosen and affects the use effect of the steel wire rope.

Embodiment Construction

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0036] Such as Figure 1 to Figure 7 Shown, a kind of hot-dip galvanized steel strand manufacturing method comprises the following steps:

[0037] S1. Pickling and impurity removal: remove the grease, iron oxide scale, rust and other residues on the surface of the steel wire rope by acid pickling;

[0038] S2, wire drawing: place the steel wire rope after pickling in step S1 on the drawing machine, draw the steel wire rope for multiple passes through the drawing machine, and take up the wire through the I-shaped wheel;

[0039] S3, hot-dip galvanizing: the steel wire rope drawn in step S2 is sent to the inside of the galvanizing tank for hot-dip galvanizing;

[0040] S4. Twisting and twisting: install the I-shaped wheel wound with hot-dip galvaniz...

Abstract

The invention relates to a hot-dip galvanized steel strand manufacturing method. A device comprises a bottom plate, a stranding device and a twisting device, the stranding device is mounted on the left side of the upper end of the bottom plate, and the twisting device is arranged on the right side of the stranding device and mounted on the bottom plate. The manufacturing method can solve the problems that when existing equipment strands a steel wire rope, the steel wire rope is poor in positioning effect and inaccurate in position and easily rubs with a rotating disk during stranding, the surface quality of the steel wire rope is affected, the steel wire rope cannot be straightened, the stranding effect of the steel wire rope is affected, the steel wire rope cannot be compressed or twistedand is easily loosened, the use effect of the steel wire rope is affected and the like.

Description

technical field [0001] The invention relates to the field of processing hot-dip galvanized steel strands, in particular to a method for manufacturing hot-dip galvanized steel strands. Background technique [0002] The steel strand is a steel product composed of multiple steel wires. The surface of the carbon steel can be added with galvanized layer, zinc-aluminum alloy layer, aluminum-clad layer, copper-plated layer, epoxy resin, etc. according to the application. It can be divided into prestressed steel strands, (for electric power) galvanized steel strands and stainless steel strands. Among them, the prestressed steel strands are coated with anti-corrosion grease or paraffin and covered with HDPE. They are called unbonded prestressed steel strands. Stressed steel strands are also made of galvanized or galvanized aluminum alloy steel wire. [0003] At present, the existing hot-dip galvanized steel strands usually have the following defects in the manufacturing process: 1. ...
