Modular analysis of kinematics performances for multi-link mechanical presses

机械压力机适用于薄板件拉深、成形、弯曲、冲裁等冷冲压工艺。进行多连杆压力机的杆系类型分析;基于杆组法建立其模块化性能分析方法;进行多连杆压力机的模块化运动学性能分析软件开发;基于所开发的模块化压力机性能分析软件,进行了对称六连杆肘杆压力机和对称八连杆肘杆伺服压力机的算例分析。研究为多连杆压力机的杆系设计提供了辅助分析工具。

Mechanical press is a machine tool suitable for cold stamping processes such as, drawing, forming, bending, punching, etc. First, the current press linkages were categorized. Then, a modular performance analysis method was proposed based on the Assur＇s groups, based on which a modular program was constructed for the kinematic performance analysis of multi-link mechanical presses. Finally, two examples, i. e, , six-link double-knuckle press and eight-link double-knuckle servo press, were given to illustrate the proposed method and program. The research is helpful to the linkage design of multi-link mechanical presses.
