Roll-bending device capable of achieving function exchange of four-high mill and six-high mill

Abstract

The invention discloses a roll-bending device capable of achieving the function exchange of a four-high mill and a six-high mill. The roll-bending device comprises roll-bending block guide rails, upper roll bending blocks, upper hydraulic cylinder components and lower roll bending blocks, wherein the roll-bending block guide rails are arranged in bilateral symmetry; the upper roll bending blocks and the lower roll bending blocks are connected through piston rods of the upper hydraulic cylinder components; the lower roll bending blocks are provided with lower hydraulic cylinder components; theroll-bending device further comprises stop blocks arranged at the terminals at the bottoms of the roll-bending block guide rails and connected with mill housings; the bottom ends of piston rods of the lower hydraulic cylinder components can be propped against the stop blocks; and the upper hydraulic cylinder components and the lower hydraulic cylinder components achieve the servo-driven control through a rolling mill master control system respectively. The roll-bending device with a reasonable structure can conveniently achieve the function exchange of the four-high mill and the six-high milland effectively ensures the profile and the quality of a rolled plate.

Description

technical field [0001] The invention relates to a roll bending device of a four-six-roll interchange machine, which belongs to the steel rolling equipment technology. Background technique [0002] The four-six-high interchangeable rolling mill described in the present invention is a metal plate rolling equipment that has the functions of a four-high rolling mill and a six-high rolling mill and can realize functional interchange on the machine. [0003] The roll bending device of the present invention is a device used to overcome and eliminate the bending deformation of relative rolls. Under the working condition, because the metal plate passes between the opposite rollers, the bending deformation of the two rollers in the upper and lower relative directions is caused. The device directly affects the plate shape and rolling quality of the rolled plate. In fact, there is no so-called bending roll on the rolling mill, but a device known in the industry. [0004] Existing rol...
