A rolling stand with a bending and shifting device for rolling rolls with two lower blocks (12, 13) integrally fixed to the housing (2) and carrying a lower chock (17), two upper blocks (14, 15) connected to an upper chock (16), a shifting device (30) for the upper roll (10) connected to the upper chock by means of a sliding coupling, a shifting device (31) for the lower working roll (11) connected to the lower chock by means of a sliding coupling. The lower chock is coupled to the blocks (12, 13) by means of a sliding coupling which allows the chock (17) to be moved in a vertical direction to generate a bending of the lower roll (10) by means of actuators (20, 21). The two upper blocks (14, 15) are vertically coupled with the housing (2) to allow the upper roll (10) to be bent. The shifting movement of the upper roll (10) is achieved by means of a sliding coupling between the upper chock and the two upper blocks, and may be carried out under load while the rolling operation occurs. |
