Abstract：

A new press mechanism used in deep drawing was presented, and its feasibility was verified. Firstly, the new press mechanism that regarded as a connecting rod mechanism was elaborated. Its systematic size of movement was presented by testing the geometry structure, and the variations of the displacement, velocity and acceleration of the system were analyzed. Then，the movement size of the alterable coupling was obtained by optimization, and the solid model of press mechanism was built by the software SolidEdge. Finally, the motion simulation of the model was conducted by the software ADAMS，and the simulation result of this model was compared with the simulation result of traditional press mechanism with six connecting rods. From the comparison, it is found that the optimized velocity and acceleration of the punch are more stable than that of the traditional press mechanism (The crank is located at position of degree 90 °to 240°). This new device can complete the output motion fluently.
