Description

[0002] Wire rope is an important construction material, widely used in elevators, mines, buildings, and bridges. The product standard of wire rope requires the wire to be tested after being unstranded. The test items such as tensile test, torsion test, and repeated bending test require the wire to be straight. The unstranded wire of the wire rope is spiral-shaped, with high hardness and elasticity. Especially those with larger diameters have high strength and are difficult to straighten manually. The commonly used method at present is to knock it flat with a wooden hammer. This manual straightening method is labor-intensive, dangerous, and easy to hurt people. At the same time, the surface of the wire is severely deformed after being hit vigorously. The existing wire rope straightening device directly straightens the wire without unwinding the spiral, which will generate stress, resulting in stress concentration in the wire rope, affecting subsequent test results.
