摘　　要：提出了一种用于深冲压的新型压力机构,并对其可行性进行验证。首先,将新型压力机构等同为连杆机构,并且进行了阐述,通过测试其几何结构取得系统的运动尺寸,主要分析了压力系统的位移、速度及加速度的变化;然后,采取优化方法找出可变联轴器的运动尺寸,通过具体的实例,在Solid Edge三维软件中对压力系统构建实体模型;最后,将实体模型导入到ADAMS软件中进行运动仿真,并且与传统六连杆压力机构模型仿真结果进行了对比。研究结果表明,优化设计的冲头速度和加速度（曲柄大约位于90°~240°的角位置处）比传统六连杆压力机平稳,能很好实现深冲压的输出运动。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 struc- ture, and the variations of the displacement, velocity and acceleration of the system were analyzed. Then, the movement size of the alter- able coupling was obtained by optimization, and the solid model of press mechanism was built by the software SolidEdge. Finally, the mo- tion simulation of the model was conducted by the software ADAMS, and the simulation result of this model was compared with the simu- lation result of traditional press mechanism with six connecting rods. From the comparison, it is found that the optimized velocity and ac- celeration 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.
