Abstract：Aiming at the present problems such as low efficiency shear , low qualified cross section and high energy consumption , which happened in the process of shearing common used metal plate , a high-speed rolling shearing method with the upper blade geometric parameters is presented .It analyzed the influence of the high-speed rolling shearing method on the equivalent stress distribution , the cross section quality and the shear force , the fracture process of metal plate high-speed shearing was simulated by FEA software DEFORM-3D.Simulated results show that the optimized high-speed rolling shear with the upper blade geometric parameters can make the equivalent stress distribute evenly in the shearing area , and it can obtain the high cross section quality of metal plate;Comparing the numerical simulations with normal rolling shear , the maximum shear force are decreasing in cutting and rolling shearing , the energy saving shear is realized .
Keywords：the upper blade geometric parametershigh-speed rolling shear methodthe equivalent stress dis-tributionthe cross section qualitythe shear force
