ABSTRACT:
Device for the axial clamping/release of chocks (15) of working rolls (14) on a rolling mill stand, the rolling mill stand including an actuation side (10a-FIG. 1) and a working side (10b-FIG. 2), stationary housings (11) associated with stationary blocks (12) being comprised at the sides, each of the stationary blocks (12) being associated with a relative sliding block (13) positioned in a direction axial to the working rolls (14), each sliding block (13) defining a lodgement for a chock (15), the bearings of the working rolls (14) being lubricated with a centralized air-oil system which comprises a first part of connectors (22) located on the machine and fixed to supporting means (24) and a second part of connectors (17) included on the front of the relative chock (15), the sliding blocks (13) being associated, on the actuation side (10a), with oscillatory means (27) that clamp/release the sliding blocks (13) to/from the relative chocks (15), these oscillatory clamping/ releasing means (27) being able to move from a second position of releasing (FIG. 4) the chock (15) from the relative sliding block (13) to a first clamping position (FIG. 3), these clamping/releasing means (27) in their second releasing position acting on the means (24) that support the first part of the connectors (22) so as to clamp transversely the first part of the connectors (22) in a determined position coordinated axially with the position of the second part of the connectors (17).
