Problems solved by technology

[0004] At present, in the original production process, the traditional straightener is used. Due to the friction between the steel wire and the straightening wheel, heat is generated. The straightening wheel and the straightening wheel shaft are severely worn, and the straightening block is easily deformed by heat, which affects the quality of the steel cord. Quality; due to serious wear and deformation, the maintenance cycle of the straightener is short, the frequency of replacement parts is high, and the service life is reduced; the process adjustment is inconvenient, which is not conducive to operation

Embodiment Construction

[0021] Such as figure 1 with figure 2 As shown, the steel wire straightener of the present embodiment includes a base 1, and the base 1 is provided with an upper pressing frame 2 and a lower bracket 3 which are mutually horizontal, and the upper pressing frame 2 and the lower bracket 3 are oppositely arranged Straightening wheels 4 and straightening blocks 5 are arranged. In this embodiment, the straightening wheel shaft is made of SKH-9 imported material, which is quenched to HRC55-60°, and its wear resistance is improved through fine grinding; the straightening wheel is made of hard alloy material to improve its hardness and wear resistance The straightening block is made of H13 hot work die steel and quenched to HRC48-52°, which improves the toughness and cold and heat fatigue resistance of the straightening block.

[0022] In order to facilitate passing the steel cord on the wire passing wheel through the gap between the straightening wheel 4 and the straightening block...

Abstract

The invention relates to metal straightening equipment, in particular to a steel wire straightener. The steel wire straightener comprises a base. An upper pressing frame and a lower bracket which are parallel to each other are arranged on the base, and a straightening wheel and a straightening block are arranged at the opposite position of the upper pressing frame and the lower bracket. When the steel wire straightener is used, all-steel cords pass through the straightening wheel and the straightening block of the lower bracket and the upper pressing frame through wire-passing wheels, all-steel cord straightening effect is achieved through adjustment of interval and displacement of the wheels, the straightening effect is good, whole structure is simple, and adjustment and replacement of components are easy.

Description

technical field [0001] The invention relates to a metal straightening device, in particular to a steel wire straightening device. Background technique [0002] Made of high-quality high-carbon steel after surface coating, drawing and twisting, it is one of the main frame materials of tires. Steel tire cords include steel cords for carcass and steel cords for belts. Tire steel cords are generally twisted from monofilament strands of different diameters. The number of monofilaments and the structure of the cords vary depending on the tire specification and the location of use. [0003] In the production process of steel cord, due to the residual tensile stress and moderate compressive stress generated by steel wire drawing, the steel wire is unstable and fluctuates greatly, resulting in a large number of broken wires. In order to better filter these problems, the study found a straightener with a volume effect, which greatly and effectively improved the stability of the ste...
