摘要： The invention relates to a rolling device comprising at least two working rollers (2, 3) which are each mounted in a rolling stand (6) by means of at least one working roller chock (4, 5), wherein, to adjust a desired rolling nip (7), at least one of the working rollers (2, 3) in the rolling stand (6) can be adjusted relative to the other working roller (2, 3), in particular in the vertical direction, wherein axial displacement means (8) are provided by means of which a working roller (2, 3) can be displaced in its axial direction relative to the rolling stand (6), wherein the axial displacement means (8) comprise an actuating element (9) which is arranged coaxially to the axis (10) of the working roller (2, 3) to be displaced, and wherein at least one working roller (2, 3) is operatively connected to bending means (11) by means of which a roller can be subjected to a bending moment. In order to make it possible in a cost-effective manner to achieve the axial displacement of the working rollers with the simultaneous possibility of subjecting them to a bending moment, the invention provides that, in order to adsorb the force generated by the bending means (11), the working roller chock (4, 5) has arms (12, 13) which protrude laterally as viewed from the axis (10) of the working roller (2, 3), wherein a pressure transmission element (15) which can be displaced relative to the rolling stand (6), in particular in the vertical direction, is arranged between an element (14) of the bending means (11) that produces a pressure force, in particular a piston, and the protruding arm (12, 13) of the working roller chock (4, 5).

摘要： A bending device for two working rolls of a rolling stand is described, having guide blocks (6) provided in lateral roll housings for two vertically adjustable pressure-transmission bodies (4a, 4b), on which the working rolls (1) are supported via chocks (2), and having bending cylinders (5) which are arranged in pairs between the pressure-transmission bodies (4a, 4b) and have a piston rod (12) acting on one pressure-transmission body (4a or 4b) and a cylinder (10) formed by the respective other pressure-transmission body (4b or 4a), wherein the pressure-transmission bodies (4a, 4b) are supported on the respective guide block (6) in a sliding manner. So that loads acting on the pressure-transmission bodies can be introduced into the guide block free of edge pressure, it is proposed that the pressure-transmission bodies (4a, 4b) be supported on the respective guide block (6) in a sliding manner by self-adjusting wearing plates (7).

摘要： The invention relates to a rolling device (1) comprising at least two working rolls (2, 3) which are respectively mounted in a roll stand (6) by means of working roll assembly pieces (4, 5). At least one of the working rolls (2, 3) is adjustable relative to the other working roll (2, 3) within the roll stand (6), especially in a vertical direction, so as to adjust a desired rolling gap. At least one working roll (2, 3) is effectively connected to bending means (7), with the aid of which said working roll (2, 3) can be impinged upon by a bending moment. The working roll assembly piece (4, 5) is provided with arms (9, 10) that laterally protrude relative to the axis (8) of the working roll (2, 3) to absorb the force generated by the bending means (7). In order to improve the adjustability of the rolling device to a large ascent, a pressure-transmitting element (12) which can be displaced relative to the roll stand (6), particularly in a vertical direction, is disposed between a pressure-generating element (11) of the bending means (7), especially a piston, and the protruding arm (9, 10) of the working roll assembly piece (4, 5).

摘要： The crown (21) on a steel strip in a rolling mill is controlled by a continuous rotational adjustment of an arbor (1) in response to a control signal representing the current crown (21) profile or deviation therefrom, the arbor (1) being equipped with a series of eccentric rings (2, 3, 4, 5) fixed thereto, bearings (7) surrounding the rings, and a continuous or segmented sleeve (8) around the rings (2, 3, 4, 5). Where the sleeve (8) is segmented, use of an intermediate roll is suggested.

摘要： The invention relates to a bending device for the working rolls of a hot-rolling frame, comprising hydraulic piston cylinder units which transmit bending forces to the chucks of the working rolls, using guide elements. The invention aims to improve a bending device of this type, in such a way that the actuating forces which are to be generated are produced by a piston cylinder unit with dimensions small enough to be easily mounted into blocks which are to be provided in the windows of the frame, whilst retaining a free choice of the bearings for the support rolls. This is achieved by a double-action hydraulic piston cylinder unit (4, 5), provided for each block, whose two ends are connected to the guide elements (12, 13). Said guide elements (12, 13) encompass the free ends of the catches (20, 21) of the working-roll chucks (18, 19) on both sides by an axial displacement of the guide grooves (22, 23) which accommodate the working rolls (16, 17).

摘要： Die Erfindung betrifft ein Walzgerüst mit Stütz- und Arbeitswalzen zum Walzen von Blechen und Bändern, bei dem mindestens die in Einbaustücken innerhalb der zwischen den Ständersäulen der Walzenständer gebildeten Ständerfenster gelagerten oberen und unteren Arbeitswalzen durch gegensinniges Horizontalverschieben mittels den Einbaustücken wirkmäßig zugeordneter Verschiebeantriebe die Walzen aus der gemeinsamen Vertikalebene heraus in solche Stellungen verschiebbar sind , in denen sich die durch die Walzenachse der oberen Arbeitswalze und der unteren Arbeitswalze verlaufenden Vertikalebenen kreuzen. Erreicht wird dies dadurch, daß an den gegenüberliegenden parallel zur Walzrichtung verlaufenden Innen- und Außenseiten jeder Ständersäule (5,6) je ein Verschiebe- und Schwenklager für einen von zwei zueinander parallelen miteinander gekoppelten im wesentlichen horizontalen Balken (9) angeordnet ist, wobei jeweils die in die Ständerfenster (11) einer Ständerseite hineinragenden Enden zweier Balkenpaare das betreffende Arbeitswalzeneinbaustück der oberen (3a) und unteren Arbeitswalze (3b) beidseitig in Vertikal- und Horizontalrichtung synchron verstellbar abstützen und die jeweils anderen auskragenden Enden dieser Balkenpaare mit den Verschiebe (21) - und mit Biegezylinder (19) korrespondieren.
摘要翻译： 具有背辊的辊架和用于轧制板和带的工作辊，其中至少安装在形成在辊壳体的壳体柱之间的壳体窗口内的卡盘内的上部和下部工作辊可以水平地从它们共享的垂直平面中移出 通过与辊卡盘有效相关联的运动驱动器沿相反方向移动到通过上工作辊和下工作辊的辊的轴线的垂直平面相交的位置。 这是通过在每个壳体柱的内侧和外侧（其彼此相对并且平行于辊的方向延伸）的事实实现的，为两个基本上水平的梁中的一个布置有运动和旋转轴承。 梁是平行的，彼此连接并且在两侧延伸穿过一侧的壳体柱，梁延伸到壳体窗口中，并且在远离壳体窗口的一侧离开辊壳体。 延伸到一个壳体侧的壳体窗口中的两个梁对的相应端部支撑上部和下部工作辊的卡盘，使得卡盘在垂直和水平方向上的两侧可同步调节。 梁对的另一个突出端连接到移动装置和偏转装置。
