摘要
本设计基于有限元软件,针对多楔槽带轮旋压成形工艺进行研究,对旋压成形过程中工件所需要的工装夹具进行设计,其中包括上模、下模,导套、旋轮、顶杆以及顶出件,根据工件成形要求设计成形所需的初成形旋轮和最终成形旋轮。针对所设计的方案进行了旋压成形工艺设计,并在MARC有限元分析软件中进行旋压成形工艺数值模拟,研究了旋压成形过程中材料变形情况,对成形件的应力应变分布进行了分析。
The spinning forming process of multi-wedge groove pulley has been studied on the basis of finite element analysis. The jig for work piece that required in the spinning process has been designed including upper die, lower die, guide sleeve, spinning roller, ejector rod, and ejector part. The rough and fine spinning rollers required in the forming process as per the work piece profile have been designed. The spinning process of the proposal has been designed and numerically simulated in the MARC finite element software. The deformation of material has been studied during the spinning process. The stress-stain distribution of the formed work piece has been analyzed.
