| 摘 要： | Dynaform是基于有限元理论建立的钣金成形模拟和分析软件。拉深成形是一种常见的钣金成形方法,它的实质在于凸缘部分材料的转移和塑性变形,拉深过程中制件的主要失效形式有起皱和破裂。文章基于Dynaform分析引起起皱的各种因素以及对方盒形件拉深成形质量造成的影响,可弥补拉深模具经验设计的不足,缩短模具的设计周期,并对类似产品的模具设计具有一定的借鉴作用。

| Abstract: | Dynaform is a soft based on the FEA,and is used to simulae and analyze sheet metal forming process. Deep drawing is a common method of sheet metal forming,and its essence lies in the plastic deformation and material flow of the flange part. The main failure impacts of the quality of drawing parts are wrinkling and rupturing. Different wrinkle factors of square box part in deep drawing are analyzed based on Dynaform in this paper,this drawing die design compensates the experience design,raises the efficiency,and serves as a reference for other similar die design. |
