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...

The invention relates to a method for manufacturing a hot-dip galvanized steel strand, which comprises a base plate, a twisting device and a twisting device. A twisting device is installed on the upper left side of the bottom plate, and a twisting device is installed on the right side of the twisting device. The control device is installed on the base plate. The invention can solve the problem that the existing equipment has poor positioning effect and inaccurate positioning of the steel wire rope when twisting the steel wire rope, and the steel wire rope is prone to friction with the rotating disc during twisting, which affects the surface quality of the steel wire rope, and the steel wire rope cannot be fixed. 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.
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. ...
