Abstract：

The mathematical model of shear mechanism for a new hydraulic bilateral rolling shear was put forward based on the kinematics theory of a hybrid spatial linkage mechanism, and the forward and inverse kinematics models of shear mechanism were established taking the pure rolling shear as the goal and the hinge points between guide rod and blade as the base points. Then, the transition matrix between servo hydraulic cylinder and upper blade was determined combining with the kinematic research method of 3-RRR planar parallel mechanisms and applying the positional relationship between two coordinate systems, and the mathematical model between the displacement of servo hydraulic cylinder and the position and posture of upper blade was deduced. Therefore, the position and posture of upper blade were adjusted by controlling the displacement of piston rod for the servo hydraulic cylinder in real time, and the motion control precision of the shearing mechanism system was improved. Furthermore, when the steel plate was sheared at different step sizes,the displacement parameters of servo hydraulic cylinder were obtained by inverse calculating based on adjusting parameters of the mathematical model for shear mechanism, and the quality of pure rolling shear for shear mechanism was improved. Thus, the model parameters were provided for the design of shearing equipment.
