Abstract (en)
[origin: WO2013034433A1] Following the release of the lock on axially movable rolls, during a roll change for example, the necessary holding and/or clamping of the drive spindle heads is achieved with known devices by means of their own separate mechanical unit, which is hydraulically actuated and fastened to the base, to the roll upright or to the extension rails of the rolls. Due to the extremely restricted spatial conditions on the drive side of the rolls, a roll displacement arrangement with roll lock device and a drive spindle head holder on the drive side can often be realised only by means of complex, expansive and heavy structures. In order to structurally simplify, using suitable space and cost-saving means, the locking of the rolls and the holding of the drive spindle heads, and to enable both also on the drive side of the rolls under otherwise inadequate spatial conditions, the invention proposes combining the roll lock device (10) and the drive spindle head holder to form one compact structural unit (11), containing a swing bolt (12) rotatably arranged in a coaxial direction around the axial displacement cylinder (17), said swing bolt during operation of the roll system being swivelled in for locking and swivelled out for unlocking, wherein while the swing bolt (12) is being swivelled out, a side support arm (14), which is part of the swing bolt (12), is swivelled in as a support for the drive spindle head.
