Patent

CA 2601775

The invention relates to an apparatus for adjusting working rolls to the rolling line, in particular in four-high rolling mills, by means of at least one wedge pair (1, 1~) which acts on roll installation parts in the region between rolling stand columns (2, 2~) which are spaced apart from one another in parallel and are arranged such that they can be displaced relative to the columns (2, 2~) on a horizontal sliding path by means of a toggle lever adjustment. To this end, the wedges (1, 1~) of the wedge pair are connected to one another at a fixed spacing. In order to displace them, an arrangement of two toggle levers (4, 5) is provided, of which one lever (4) is supported on one wedge (1) by way of at least one joint (6) and the other lever (5) is supported on the opposite column (2~) by way of at least one joint (10) and both levers are connected via an adjustable-length toggle lever joint (7).

L'invention concerne un dispositif pour aligner des cylindres de travail sur une ligne de laminoir, notamment pour des cages quarto, au moyen d'au moins une paire de cales (1, 1') agissant sur des éléments de montage des cylindres et situées dans la zone se trouvant entre des montants (2, 2') de cage de laminoir espacés et parallèles, ces cales étant montées mobiles au moyen d'un dispositif de réglage par genouillère relativement aux montants (2, 2') sur une glissière horizontale et reliées entre elles avec un espacement fixe. Le déplacement est assuré par un ensemble de deux genouillères (4,5), l'une (4) appuyant sur une cale (1) par au moins une articulation (6) et l'autre (5) appuyant contre le montant opposé (2') par au moins une articulation (10), les deux leviers étant reliés par une articulation (7) de genouillères mobile dans le sens longitudinal.
