Description

Technical Field

[0001] The utility model relates to the field of steel product straightening devices, in particular to a heat-resistant and wear-resistant steel product wire straightening device. Background Art

[0002] Steel wire is a reprocessed product made from hot-rolled wire rods through cold drawing. During use, the steel wire needs to withstand alternating loads. Its performance is mainly determined by the mechanical properties of the steel wire, the surface state of the steel wire and the structure of the wire rope. In order to ensure its performance, a straightening device is required to reprocess the steel wire to prevent the steel wire from bending.

[0003] For example, a heat-resistant and wear-resistant steel product wire straightening device disclosed in the utility model with authorization announcement number CN210412297U relates to the technical field of steel products, and includes a fixing part, a first correction roller of a slide plate, a second correction roller and a driving motor. The interior of the fixing part is movably connected with the slide plate, the top of the slide plate is movably connected with the first correction roller, the top of the fixing part is movably connected with the second correction roller, and the bottom of the fixing part is fixedly installed with a driving motor. The device opens the limit shaft by pulling the handle, moves the slide plate to adjust the distance between the first correction roller and the second correction roller, pulls the handle again to lock the limit shaft, starts the drive motor, thereby driving the bevel gear group to rotate, the bevel gear group drives the transmission shaft to rotate, the transmission shaft drives the first correction roller to rotate, puts one end of the bent steel wire between the first correction roller and the second correction roller, and automatically guides the movement of the steel wire through the rotation of the first correction roller. The bent steel wire is squeezed by the two rows of first correction rollers and second correction rollers to straighten the steel wire. Due to the uncertain bending direction of the steel wire, the force applied by the device to the steel wire is mainly concentrated on the contact position with the steel wire and the first correction roller and the second correction roller, which may make the force on other bends of the steel wire uneven, affecting the straightening effect.
