Novel roll-bending device

The utility model provides a novel roll-bending device which comprises four upper roll bending blocks and four lower roll bending blocks matched with the upper roll bending blocks. Each set of roll bending blocks is provided with a hydraulic cylinder. The hydraulic cylinders comprise pressing covers, piston rods and cylinder bodies. The cylinder bodies are located in the roll bending blocks. The piston rods are located in the cylinder bodies, and the pressing covers are fixed to the roll bending blocks. The ends of the piston rods are connected with clamping blocks. The clamping blocks are clamped to the two ends of an upper roll bearing base and a lower roll bearing base of a rolling mill respectively. By means of the novel roll-bending device, the problem that a multi-roll rolling mill of a small-roll-diameter roll system is insufficient in space so that a bending roll cannot be used is solved, and a guarantee is provided for producing ultra-thin and ultra-wide foil good in plate shape.
