Rolling device

Abstract

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 ).
