Motion and statics analysis of generalized knuckle mechanism used in cold forging press

HU Xiao-hu,JIN Wei,XU Chao,CHEN He-jin,LI Jiang-guo,LI Ya-jun(Beijing research institute of mechanical and electrical technology,Beijing 100083,China)  
The statics and kinematics models of the generalized knuckle mechanism were set up.Through the motion analysis of this mechanism,the smoothness of the velocity and acceleration were obtained which was suitable for cold forging.Through the static analysis,the force of each pole and the input torque of the eccentric shaft in different working conditions were obtained which provided the basis for the strength design of the poles and the selection of the clutch.Moreover,considering the press may be overloaded,the posibility on this situation that the press may be sliding or jamming was further analysised.The result shows that the cold forging press would not be jammed.
