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SolidEdge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 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.
