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 type of pressure mechanism for deep drawing was proposed and its feasibility was verified. First of all, the new pressure mechanism is equivalent to the link mechanism, and has been described, by measuring the geometric structure of the system to obtain the size of the movement, the pressure system is mainly analyzed the displacement, velocity and acceleration changes; and then to optimize the method to identify Change the movement size of the coupling, through the concrete example, build the solid model to the pressure system in Solid Edge software; finally, import the solid model into the ADAMS software for the movement simulation, and compare with the traditional six-link pressure mechanism model simulation The results are compared. The results show that the optimal design of the punch speed and acceleration (about the crank at the angular position of 90 ° ~ 240 °) than the traditional six-bar press smooth, well to achieve deep-drawn output movement.
