Material selecting and manufacturing method of integral baling steel wire knot

Abstract

The invention relates to a material selecting and manufacturing method of an integral baling steel wire knot. The method comprises the following steps of selecting an alloy spring steel wire as the manufacturing material of the integral baling steel wire knot, and adopting a processing method using cold drawing as the main process. The specification of the selected alloy spring steel wire is 72B coil wire. The processing method using cold drawing as the main process comprises the following steps of selecting of 72B coil wire, pickling, phosphatizing, cold drawing, galvanizing, forming of steel wire knot, inspecting, packaging and warehousing. As the 72B alloy spring steel is used as the manufacturing material of the integral baling steel wire knot, the yield strength and fatigue strength of the steel wire knot are higher. As the processing method using cold drawing as the main process is adopted, the yield strength of the steel wire knot after being subjected to the cold-processing strengthening is higher. Compared with the traditional integral baling steel wire knot, the method has the advantages that the rigidity is high, the elasticity is high, the anti-yield capability and anti-fatigue capability are high, the buckling is firm and stable, the recycling is realized, and the like.

Description

technical field [0001] The invention relates to a one-piece packaged steel wire buckle, in particular to a selection material and a manufacturing method of a one-piece packaged steel wire buckle, belonging to the field of metal product manufacturing. Background technique [0002] In the bundling of items with a large expansion coefficient such as packaging, the traditionally used one-piece packing wire buckle usually chooses ordinary carbon structural steel as the material for making the wire buckle. Its manufacturing process is also very simple, just bend the two ends of the fixed-length steel wire into a hook shape and get final product. Such one-piece packaged steel wire buckle has large plastic deformation and poor rigidity. Therefore, in actual use, the phenomenon of deformation and sliding of the wire buckle often occurs. In order to ensure that the binding of articles is firm and strong, people hope to have a one-piece packing wire buckle with good steel, high elast...
