Cluster mill, in particular sexto - roll stand, with an axially shifting - and holding device for displaceably supported intermediate rolls and / or working rolls

摘要

A cluster mill has an axially shifting - and a holding device for displaceable between - and / or working rolls (11) and the chocks (7) are provided in the roll stand posts (1) is slidingly guided; the rollers (11) by way of pistons - cylinder - units (5) can be displaced axially in opposite directions and the piston rods (5a) are connected to a main traverse (4) connected in an articulated manner. In order by uneven loading of the pistons - cylinder - units (5) during the displacement damage to the main traverse (4) to be avoided, it is provided that on both sides of the rolls - chock (7) moving beams, (1a) is arranged in each case via a connecting traverse (2) in the roll stand posts (1) are mounted, that the connecting cross-pieces (2) in the middle of the main traverse (4) are articulated, the piston rods (5a) of the pistons - cylinder - units (5) at the ends (4a, 4b) of the main traverse (4) are articulated and in that each piston - cylinder - unit (5) by means of a path generator (10) can be controlled as a function of distance.
