High-strength steel strand manufacturing and processing equipment and processing technology

Abstract

The invention relates to high-strength steel strand manufacturing and processing equipment and a processing technology. The equipment comprises two traction guiding devices used for guiding in and guiding out of a steel strand, a coating device, a wind finishing and drying device and three series connection frames. According to the equipment provided by the invention, automatic coating and automatic drying shaping can be directly carried out on the steel strand which is subjected to stranding shaping and stress relief, rolling packaging can be carried out immediately after shaping, and the equipment can adapt to the whole streamlined manufacturing and processing process of the steel strand; and compared with an existing spraying mode which widely adopts electrostatic spraying, the equipment provided by the invention has the outstanding advantages of simple structure, convenience in assembly, low equipment cost, no risk in operation, strong coating adhesive force, uniform and smooth coating and the like, and the problems that an existing electrostatic spraying processing mode is poor in coating distribution uniformity, high in operation risk and high in equipment cost input are solved.

Description

technical field [0001] The invention relates to the technical field of steel strand processing and manufacturing, and specifically provides a high-strength steel strand manufacturing and processing equipment and processing technology. Background technique [0002] High-strength steel strand is a steel cable composed of several high-strength cold-drawn steel wires twisted. Steel strand is widely used in various fields of engineering construction. In order to meet the needs of different fields and use environments, and improve the performance and corrosion resistance of steel strands, galvanized layers, zinc-aluminum alloy layers, aluminum-clad layers, and copper-plated layers can be added to the surface of the steel strands as required. , Epoxy resin, etc. [0003] Steel strands are sprayed on the surface to obtain steel strand products with corresponding coatings. Take epoxy resin-coated steel strands as an example. Epoxy-coated steel strands refer to coating a layer of ant...

AI Technical Summary

Problems solved by technology

[0004] 1) The steel strand is a twisted structure, so the steel strand itself has an uneven structure, and the existing electrostatic spraying method for coating spraying is prone to uneven coating distribution, which affects the final coating. coverage quality;

[0005] 2) During the electrostatic spraying process, workers are required to strictly follow the operating standards, and there are greater risks of electric shock and fire accidents during the operation;

[0006] 3) Electrostatic spraying requires the purchase of a large number of corresponding equipment, so the equipment cost is relatively high
