Abstract

Bei einer Biege- und Ausbalanciervorrichtung für axial verschiebbare Arbeitswalzen eines Quartowalzgerüstes sind beidseitig im Fenster jedes Walzenständers je ein orts­ fester Führungsblock befestigt, wobei die Kraft von Biege­ zylindern auf die in Achsrichtung und vertikal verschieb­ bar geführten Arbeitswalzeneinbaustücke übertragen wird. With a bending and balancing device for axial sliding work rolls of a four-high rolling mill are one location on both sides in the window of each roller stand fixed guide block attached, using the force of bending cylinders on the axially and vertically bar-guided work roll chocks is transferred.

Zur Schaffung einer robusten, betriebssicheren Biege- ­ und Ausbalanciervorrichtung mit kippmomentfreier Über­ tragung der Biege- und Verschiebekräfte auf die Arbeits­ walzeneinbaustücke (4, 5) und vertretbaren Reibungen zwischen Führungsflächen sind die Arbeitswalzeneinbaustücke (4, 5) beidseits mit je einer im mittleren Höhenbereich angeordneten Gleitflächen (25, 27) an einem Führungsab­ satz (24, 26) eines unteren bzw. oberen am Führungs­ block (12, 13) vertikal geführten Hubgehäuses (14 bzw. 15) abgestützt, wobei jedem Hubgehäuse (14, 15) auch im Höhen­ bereich des jeweils anderen Hubgehäuses (15 bzw. 14) Führungs flächen (21a, 18a) zugeordnet sind. To create a robust, reliable bending and balancing device with overturning torque free transfer of bending and displacement forces to the work roller chocks (4, 5) and reasonable friction the work roll chocks are between the guide surfaces (4, 5) on both sides with one in the middle height range arranged sliding surfaces (25, 27) on a guide set (24, 26) of a lower or upper on the guide block (12, 13) vertically guided lifting housing (14 or 15) supported, each lifting housing (14, 15) also at heights area of the other lifting housing (15 or 14) guide surfaces (21a, 18a) are assigned.
