[0002] The technical background of the correction device for high-strength alloy spring steel wire involves the application requirements of alloy spring steel wire, the role of the correction device and the technical requirements. The design and application of such a device is helpful to improve the quality and production efficiency of alloy spring steel wire products.

[0003] The patent specification with announcement number CN 220127476 U discloses a correction device for alloy spring steel wire for high-strength operation. A workbench is set up, and a correction mechanism for steel wire correction is provided on the right side of the upper end of the workbench, and a disassembly mechanism for U-shaped perforated support broken plate is provided on the left side of the upper end of the workbench.

The left side of the first roller shaft is fixedly connected with a first gear, and the first gear is meshingly connected with a second gear. The second gear is internally fixedly connected to one side of the second roller shaft, and the other side of the second roller shaft is rotatably connected with a first perforated vertical rod, and the bottom of the first perforated vertical rod is fixedly connected to the workbench. In the utility model, through the correction mechanism, the effect of extrusion correction of the spring steel wire is achieved, and the problem of bending of the spring steel wire is solved.

At the same time, the device fixes the steel wire by a hinge plate, and cannot fix steel wires of different diameters. For this reason, we proposed a correction device for high-strength alloy spring steel wire. Utility Model Content
