AI Technical Summary
Existing straightening equipment cannot effectively solve the problem of conveying trajectory deviation caused by changes in steel coil thickness, which affects the straightening quality of steel bars.
By dynamically adjusting the bracket tilt angle, combined with a laser rangefinder and a servo motor-driven worm gear structure, the tilt angle of the guide roller is automatically adjusted, forming a closed-loop control to compensate for the conveying trajectory deviation caused by changes in the thickness of the steel coil, and to eliminate the bending deformation of the steel strip through a multi-stage straightening component.
Ensure that the steel bars are conveyed along the central axis of the straightening channel to improve the straightening quality, avoid secondary deformation of the steel bars due to conveying deviation and excessive clamping force, and improve the applicability and reliability of the device.
