AI Technical Summary

Technical Problem

When the roller pressing device operates continuously for a long time, heat accumulates on the surface of the roller, causing the temperature to rise. This affects the hardness and wear resistance of the roller, and reduces the thickness control accuracy and pass rate of the variable thickness decorative aluminum material.

Method used

A roller pressing device for decorative aluminum materials with variable thickness was designed. It adopts a combination of fixed roller pressing unit and movable roller pressing unit. The movable roller body is equipped with a cooling channel. The cooling medium absorbs heat and sprays it onto the surface of the aluminum material to achieve precise adjustment of the roller pressing gap and cooling.

Benefits of technology

It improves the production range and service life of the rolling mill, reduces processing costs, enhances the appearance quality and yield of aluminum materials, and prevents surface oxidation and discoloration.
