AI Technical Summary

⚠Technical Problem

In the existing hot-rolled ribbed steel bar straightening device, the lack of limiting guide at the bending part of the steel bar during the straightening process leads to slippage and straightening misalignment failure.

⚗Method used

The fixed clamp and the inner arc-shaped recess of the movable clamp are used to fit tightly against the surface of the steel bar. The anti-rotation groove at the upper end of the movable clamp restricts the steel bar from slipping. The heating wire in the recess heats the steel bar to a thermoplastic state. The telescopic push rod and the straightening slider of the straightening part are used to apply the straightening force precisely.

🎯Benefits of technology

It effectively prevents the steel bars from slipping and rotating during the straightening process, improves the straightening accuracy and success rate, ensures that the steel bars are straightened along the preset direction, reduces the straightening difficulty and improves efficiency.
