ABSTRACT:
Device for the crossed displacement of rolling rolls (10), whether they be working rolls and/or back-up rolls, in a rolling mill stand (11) for plate and/or strip, the rolls (10) being supported at the ends by respective supporting chocks (12) associated to stationary housing (13), the chocks including an inlet side and an outlet side, the chocks (12) on one roll (10) being associated with the device to position the rolls (10) in a crossed position, cooperating with at least one of the inlet and outlet sides of the chocks (12) of at least one roll (10), there also being a front cam (16), whose axis lies on a substantially parallel plane to the rolling plane, associated with drive shafts (15), the front cam (16) comprising at least two substantially cylindrical coaxial elements (17, 18), one connected to the drive shaft (15) and the other cooperating with the chock (12), the front cam (16) including front surfaces of reciprocal connection (19, 20) defining inclined radial sliding planes and at least two principles, the rotary movement imparted to the front cam (16) being functional to the lateral displacement of the chock (12).
