Abstract The purpose aims to improve the plate shearing section quality and metal yield by means of optimal blade clearance adjustment model of rolling-cut shear and accurate calculation of the maximum shearing force, as well as for the system optimization design, structure optimization design to provide important basis. A 3500 mm rolling shear of a large stainless steel factory was taken as the test object, and the blade clearance under different influence factors of the clearance value and the shearing section were tested. The optimized production accumulated data regression analysis and the rolling shear process of stainless steel shear test. The test results show that the optimal blade clearance adjustment module is a comprehensive function, which include steel plate thickness, material, temperature and shear plate volume. The shear stress at starting stage with the relative penetration depth increases affected by the above factors, and the fracture peak decreases rapidly after being cut into the roll phase constant.
