Roll stand for absorbing rolling forces

Abstract

In order to simplify roll adjustment in a roll stand when changing the rolls, a roll stand absorbs rolling forces of at least three rolls mounted on both sides in bearing seats of the roll stand that absorb rolling forces, in each instance. At least the bearing seats of one roll are disposed in a stand body jointly with a bearing seat of another roll, in each instance. One of the stand bodies has fixed bearings of the two related rolls, in each instance, and / or one of the stand bodies has floating bearings of the two related rolls, in each instance.

AI Technical Summary

Benefits of technology

The patent text describes two bearing variants for a stand body that can hold two rolls. In the first variant, both rolls have fixed bearings, allowing for precise positioning without needing complicated adjustments. In the second variant, the bearings are floating, which makes it easier to adjust the position of the stand body. These variations help achieve smaller roll stand dimensions, better forming conditions, improved material yield, lower costs, and a compact, stable construction with minimized space requirement.

Problems solved by technology

It is understood that refitting of such rolling machines to a different roll pass or also wear-related refitting is connected with a correspondingly great refitting effort, because the roll elements fixed in place on the quick-release roll shafts on each of the roll stands have to be replaced accordingly, in order to set the rolling machine to the new roll pass.
