摘要
本文提出了一种新型的金属板材无模成形方法,即高压水射流柔性渐进成形方法,并基于此方法设计出一套五轴成形装置,其中喷嘴具有二个旋转自由度,工作台具有三个平动自由度,具有很好的柔性,非常适合多品种小批量产品的生产和新产品的试制。对高压水射流柔性渐进成形装置的各个子系统进行了详细的介绍,并对成形过程提出了一种新的仿真分析方法,将比较复杂的流固耦合问题,简化为加载等效压强的方法。最后通过单点水柱成形的仿真分析,揭示射流压力和板厚对金属板材成形性能的影响。
This paper presents a new method of dieless sheet metal forming,water jet incremental sheet metal forming(WJISMF).A five-axis WJISMF machine was designed based on this technology.The machine has five degrees of freedom(DOF) including two rotational DOF of the nozzle and three translational DOF of the workbench.It has good flexibility and can be used for low cost production of prototype.The paper introduces the subsystems of WJISMF system.In addition,a new simulation method for the forming process is given,in which the complex simulation about fluid-structure interaction is simplified by loading equivalent pressure.The effect of water jet pressure and sheet thickness on the metal forming accuracy is evaluated by simulation analysis respectively.
