Plan design of mechanical transmission system is the key of mechanical press design. Compared with the traditional mechanical press, the transmission plan design for servo mechanical press is fundamentally different. Based on the analysis of load characteristics in forming process of mechanical press, the differences of design criterion and design focus between traditional mechanical press and servo mechanical press were pointed out. After reviewing the development history of transmission plan design for mechanical press, the differences of design objective and design idea between traditional mechanical press and servo mechanical press were commented. Aiming at the constrained coupling problem between slide stroke and mechanical advantage of working mechanisms with single servo input, an asymmetric parallel working mechanism with double servo input was proposed, which could decouple the kinematics performance index and dynamics design objective. The above analysis may provide a reference for the transmission plan design of servo mechanical press.
