Abstract
The present invention relates to a device for guiding a movable element, in particular a driving bar of a mandrel or a mandrel, in a rolling mill with mandrel. The device according to the invention comprises a support structure for the advancement of the movable element along an advancement direction. The device comprises a first slide and a second slide which are carried by said support structure and are slidable along a transverse direction which is substantially orthogonal to said advancement direction, in which each slide carries two abutment surfaces for guiding the movable element and in which each slide is movable along said transverse direction between at least a first operating position, upon reaching which said abutment surfaces are susceptible to coming into contact with a movable element of a first predefined diameter, and at least a second operating position, upon reaching which said abutment surfaces are susceptible to coming into contact with a movable element of a second predefined diameter. According to the invention, the device comprises actuating means which move the slides along the transverse direction between the operating positions and lock the slides themselves when one of said operating positions is reached.
