[0002] Flux-cored wire, as an important welding material, is widely used in industries such as ships, bridges, and construction. However, since flux-cored wire may bend, twist, or undergo other deformations during production, transportation, and use, it needs to be straightened to ensure its quality and welding effect.

[0016] 1. By setting up an adjustment mechanism, when the distance between the straightening rollers needs to be adjusted, the straightening rollers are started, and the welding wire to be straightened is placed between the upper and lower straightening rollers. The movement of the straightening rollers will straighten the welding wire. When welding wires of different sizes need to be straightened, the bidirectional threaded rod is twisted.

When the shock-absorbing plate contacts the baffle 2, the angle between the two connecting blocks 3 and the two connecting rods will change, the spring 2 will contract, and the angle between the two connecting rods and the two connecting blocks 2 will change. At this time, the position of the shock-absorbing plate moves backward to reduce the shock of the descent of the tool. The spring damper will assist in reducing the shock of the tool, so that the error caused by vibration during the cutting process can be reduced, ensuring that the welding wire is cut accurately and stably. This is especially important for welding wire that requires high-precision cutting, and can ensure the accuracy of the cutting length and cross-sectional flatness.
