AI Technical Summary

⚠Technical Problem

During the hot rolling of aluminum, the alignment and adjustment of the work rolls and roller brushes require continuous manual intervention, which can easily damage the universal coupling and motor bearings at the motor output end, affecting the roll changing efficiency of the rolling mill and increasing labor intensity.

⚗Method used

An automatic centering mechanism for aluminum hot rolling work rolls was designed. Through the combination of rollers, centering guide columns, universal couplings and V-blocks, the mechanism ensures that the rollers remain coaxial during axial movement, avoiding collisions with the universal couplings and motor bearings. The rollers are driven by hydraulic cylinders and driven by gear meshing to achieve automatic centering.

🎯Benefits of technology

It improves the centering stability of the work roll brush and the roll changing efficiency of the rolling mill, reduces labor intensity, avoids equipment damage, and extends the service life of the equipment.
