Kinematic Analysis of Clamping and Rotating Mechanism
In order to realize accurate rotation of steel pipe in automatic rolling pipe bender, a tilt cylinder six bar mechanism driven by pneumatic cylinder was presented. Based on the analysis of mechanism motion’s state, the motion process was divided into three working stages: clamping, rotating and loosening back. And kinematics parameters in every phase of the mechanism were obtained by complex number vector method, furthermore the mechanism kinematics characteristics of the whole process were gained. The results of the simulation example indicated that the mechanism has less change in velocity and more smooth motion during clamping and rotating stages.
