Abstract
A bending device for two working rolls of a rolling stand. Guide blocks provided in lateral roll housings for guiding two pressure-transmission bodies vertically adjustably with respect to each other and, on which the working rolls are supported via chocks. Bending cylinders are arranged in pairs between the pressure-transmission bodies at each end of the rolls. Each cylinder has a piston rod acting on one pressure-transmission body and a cylinder at the respective other pressure-transmission body. Each pressure-transmission body is supported on a respective guide block in a sliding manner. So that loads acting on the pressure-transmission bodies can be introduced into the guide block free of edge pressure, the pressure-transmission bodies are supported on the respective guide blocks in a sliding manner by self-adjusting wearing plates which include surfaces that enable both sliding and pivoting of the bodies with respect to the guide blocks.
