Abstract (en)
[origin: EP0623401A1] A bending block for bending the rolls (5, 6) of multiroll rolling stands. On both sides of the chocks (9, 10) of the pair of rolls (5, 6) to be bent, the bending block (7, 8) is rigidly connected to the window crossbeams (1 and 2) of the rolling stand. In each of the bending blocks (7, 8), pairs of partial bending jaws (11a, 11b; 12a, 12b; 13a, 13b; 14a, 14b) are guided so as to be displaceable in the directions of bending and are driveable by means of piston-cylinder units. The pairs of partial bending jaws (11a, 11b; 12a, 12b; 13a, 13b; 14a, 14b) act by means of pressure bearing surfaces on pressure-accepting surfaces on the chocks (9, 10), each of these pressure-accepting surfaces being assigned to one direction of bending. Each pair of bending jaws consists of partial bending jaws which can be driven independently in opposite directions and the pressure bearing surfaces of which are each assigned to one direction of bending. <IMAGE>
