Description

Technical Field

[0001] The utility model relates to a conveniently fixed straightening device for processing prestressed steel strands, belonging to the technical field of steel strands. Background Art

[0002] Stranded steel wire is a steel product composed of multiple steel wires twisted together. The carbon steel surface can be coated with galvanized layer, zinc-aluminum alloy layer, aluminum clad layer, copper plating layer, epoxy resin coating, etc. as needed. The manufacturing process is divided into single wire manufacturing and stranded wire manufacturing. Wire drawing technology is used to make single wire. Depending on the product, the material can be high carbon steel wire rod, stainless steel wire rod or medium and low carbon steel wire rod. If galvanizing is required, electroplating or hot-dip galvanizing should be carried out on the single wire.

[0003] During the processing of steel strands, in order to improve or ensure the straightness of the steel strands and reduce or eliminate the bending and twisting generated during material processing and transportation, the steel strands need to be straightened, so straightening equipment is needed. However, during use, the existing steel strand straightening equipment may not be convenient for adjusting the spacing between the upper and lower pressure wheels. Inappropriate pressure wheel spacing may not be able to adapt to steel strands of different diameters, thereby affecting the straightening effect and causing the steel strands to bend or twist during the straightening process. In addition, too tight a spacing may cause excessive friction and pressure on the surface of the steel strand, thereby causing damage or breakage to the surface of the steel strand. Conversely, too loose a spacing may make the steel strand unstable when passing through the pressure wheel, affecting the straightening quality.

[0004] Therefore, a straightening device for prestressed steel strand processing which is convenient for fixation is proposed. Utility Model Content
