The invention relates to a multi-roll layer cutting metal plate shearing machine, which belongs to the field of mechanical manufacture and comprises a plurality of rigid rolls, a hydraulic cylinder, a transmission part and an auxiliary shearing mechanism. The multi-roll layer cutting metal plate shearing machine is characterized in that the rigid rolls successively lowered from left to right are slidably mounted on a rigid support in parallel, the hydraulic cylinder is mounted on the rigid support by means of a pin hinge, the end of a piston push rod is directly connected with the rigid rolls or connected with a roll system support, the transmission part is connected with the rigid support and mounted on a movable beam, and the movable beam is slidably connected with a frame. The multi-roll layer cutting metal plate shearing machine has the advantages that the rigid rolls are used for shearing a metal plate layer by layer and driven to move ahead by a transmission mechanism, larger shearing force can be decomposed on each rigid roll so that wear of a blade is decreased, the shearing mechanism moving independently is convenient in maintenance and low in manufacturing cost, the drawing force of the blade for the plate in the length direction of the blade is decreased as the rigid rolls are in rolling movement, and the quality of a shearing section is improved.
