Abstract

Die Erfindung betrifft eine Biegevorrichtung für Vier- oder Mehrwalzengerüste mit Arbeitswalzen, Stützwalzen und gegebenenfalls zwischen Arbeitswalzen und Stützwalzen angeordneten Zwischenwalzen, bei denen beidseitig an jedem Lagereinbaustück der Walzen Biegeblöcke angreifen, die in den Fenstern des Walzgerüstes vertikal geführt sind, wobei die sich jeweils vertikal gegenüberliegenden Biegeblöcke eines Walzenpaares über Kolben-Zylindereinheiten aufeinander zu- und voneinander weg bewegbar sind. Dabei greift an jedem Lagereinbaustück (5,6) beidseitig je ein zweiter vertikal verschiebbar geführter Biegeblock (16,17) an, der unabhängig von dem ersten Biegeblock (8,9) über eine sich am Walzenständer (7) abstützende Kolben-Zylinder-Einheit (18) bewegbar ist.

Figure 00000001
The invention relates to a bending device for four or multi-roll stands with work rolls, back-up rolls and, if appropriate, intermediate rolls arranged between work rolls and back-up rolls, in which bending blocks act on both sides of each bearing chock of the rolls, which are guided vertically in the windows of the roll stand, the vertically opposite one another in each case Bending blocks of a pair of rollers can be moved towards and away from one another via piston-cylinder units. A second vertically displaceable bending block (16, 17) acts on each bearing chock (5, 6) on both sides, which is independent of the first bending block (8, 9) via a piston-cylinder unit supported on the roller stand (7) (18) is movable.
