ABSTRACT:
Device for the crossed displacement of rolling rolls, whether they be back-up rolls (11) and/or working rolls (12), in a four-high rolling mill stand for sheet and/or strip, a back-up roll (11) and the relative working roll (12) defining a rolling block, with a stationary housing (14) having an inner chamber (26) to house and position the chocks (13) supporting the rolls (11, 12), in cooperation with at least one side of at least one chock (13) there being an intermediate positioning element (15) which has its outer lateral surface (18) facing towards the vertical wall of the inner chamber (26) of the stationary housing (14), the outer lateral surface (18) being a double inclined plane (18a, 18b) inversely orientated in a vertical direction, each inversely orientated part (18a, 18b) of the double inclined plane cooperating with a relative sliding displacement element (21) having inclined plane front surfaces (21a) mating with the double inclined plane surface (18) and sliding surfaces (27) cooperating with the vertical wall of the inner chamber (26), the sliding displacement elements (21) being associated with screw-type drive means (20) having, for each sliding displacement element (21) associated with the same intermediate positioning element (15), connecting threads (22a, 22b) with opposite orientation.
