Universal rolling stand with roll gap control

摘要

A universal rolling stand with control of the space between the rolls comprises a pair of horizontal rolls and one or more vertical rolls with respective chocks, positioning housings and a guide for the chocks with adjustment tie rods (6, 7, 6′, 7′, 18, 18′, 19, 19′) anchored on one side to the housings and acting on the chocks for the adjustment and positioning of the rolls. Adjustment is performed by means of hydraulic capsules (8, 8′, 9, 9′, 20, 20′, 21, 21′) with two hydraulic chambers with dual actuation effect and a double stem at the ends of each tie rod.
