Title:
【発明の名称】ロールスタンドのロールを軸方向で摺動させるための駆動装置
Document Type and Number:
Japanese Patent JP2653376
Kind Code:
B2
Abstract:
The rolls of a rolling mill can be axially moved by way of an actuator device equipped with piston-and-cylinder units. The bearing blocks which receive the journal ends of the rolls to be moved are horizontally guided in separate guide bodies. The guide bodies, in turn can be shifted vertically in cylinder blocks arranged at the flanks of the windows of the respective base member, or in pressure plates associated with such cylinder blocks. The actuator device is characterized by a compact design which even during exchange of rolls is contained in the confines of the roll stand, and it can be easily coupled to the rolls to be moved. The guide bodies of at least one base member are formed with lateral projections at which are mounted the motive power providing hydraulic cylinders, and these are connected in such a way that the piston rods thereof point in the direction of the guide bodies. The heads of the piston rods of two superimposed arranged piston and cylinder units are respectively connected by way of a vertical yoke. The vertical yoke in turn can be connected to the mounting element which is guided in the guide bodies, and it can be disconnected, particularly for the exchange of the working rolls.
