Abstract

Das mit der Zielsetzung eines vereinfachten Einbaus und Ausbaus der Walzen sowie einer Vereinfachung der Gerüstkonstruktion entwickelte Mehrwalzengerüst, insbesondere ein Sextowalzgerüst (1) ist mit einer oberen und einer unteren Arbeitswalze (2, 3) ausgerüstet, die in Einbaustücken (4, 5) gelagert sind, ferner mit einer oberen und einer unteren Zwischenwalze (6, 7), die in Einbaustücken (8, 9) lagern, sowie mit einer oberen und einer unteren Stützwalze (10, 11), deren Lager in einem oberen und einem unteren Einbaustück (12, 13) angeordnet sind. Das Sextowalzgerüst (1) weist ferner zwei in die Fenster (16) der beiden Walzenständer (14, 15) integrierte Funktionseinheiten mit je vier symmetrisch und parallel zur Walzenachsenebene (17-17) angeordneten, hydraulischen Stellzylindereinheiten (18, 18; 19, 19) auf, wobei jede Stellzylindereinheit (18, 19) aus einem oberen Stellzylinder (18a, 19a) mit einem oberen, auf das Einbaustück (12) der oberen Stützwalze (10) wirkenden Stellkolben (20a, 21a) und einem unteren Stellzylinder (18b, 19b) mit einem unteren, auf das Einbaustück (13) der unteren Stützwalze (11) wirkenden Stellkolben (20b, 21b) zum Ausbalancieren der Stützwalze (10) besteht und die beiden Stellzylinder (18a, 18b; 19a, 19b) jeder Stellzylindereinheit (18, 19) koaxial in einem gemeinsamen Zylindergehäuse (22, 23) eingebaut sind, das durch einen Boden (22a, 23a) in zwei Zylinderkammern (21b, 21c; 23b, 23c) aufgeteilt ist, sowie auf den Stellzylindern (18a, 18b; 19a, 19b) der Stellzylindereinheiten (18, 19) hydraulisch verschiebbare, doppeltwirkende, eine Biegung der Zwischenwalzen (6, 7) und der Arbeitswalzen (2, 3) bewirkende Stellhülsen (24a, 24b; 25a, 25b),die mittels Nasen (26) an den Einbaustücken (8, 9; 4, 5) der Zwischenwalzen (6, 7) und der Arbeitswalzen (2, 3) angreifen.

Figure 00000001
The multi-roll stand, which was developed with the aim of simplifying the installation and removal of the rolls and simplifying the stand construction, in particular a sexto roll stand (1) is equipped with an upper and a lower work roll (2, 3), which are mounted in chocks (4, 5) , further with an upper and a lower intermediate roller (6, 7), which are stored in chocks (8, 9), and with an upper and a lower support roller (10, 11), the bearings of which are in an upper and a lower chock (12 , 13) are arranged. The sexto roll stand (1) also has two functional units integrated into the windows (16) of the two roll stands (14, 15), each with four hydraulic actuating cylinder units (18, 18; 19, 19) arranged symmetrically and parallel to the roll axis plane (17-17) Each actuating cylinder unit (18, 19) consists of an upper actuating cylinder (18a, 19a) with an upper actuating piston (20a, 21a) acting on the chock (12) of the upper support roller (10) and a lower actuating cylinder (18b, 19b ) with a lower actuating piston (20b, 21b) acting on the chock (13) of the lower support roller (11) for balancing the support roller (10) and the two actuating cylinders (18a, 18b; 19a, 19b) of each actuating cylinder unit (18, 19) are installed coaxially in a common cylinder housing (22, 23) which is divided by a floor (22a, 23a) into two cylinder chambers (21b, 21c; 23b, 23c), and on the actuating cylinders (18a, 18b; 19a, 19b) the actuating cylinder units (18, 19) hydrauli sch displaceable, double-acting adjusting sleeves (24a, 24b; causing the intermediate rolls (6, 7) and the working rolls (2, 3) to bend). 25a, 25b) which engage on the chocks (8, 9; 4, 5) of the intermediate rolls (6, 7) and the work rolls (2, 3) by means of lugs (26).
