Dynaform窄形拉深件成型工艺影响因素研究
Research on Influence Factors on Forming Process for Narrow Drawing Parts Based on Dynafrom Software
摘要
Abstract
The effects of metal sheet drawing process parameters such as blank holding force,punch chamfer,blank size and drawing shape on the quality of narrow drawing parts were analyzed based on Dynaform software.The results show that the forming defects in narrow drawing parts often locate two short side.The little bank holding forces cause wrinkles,and the large bank holding forces cause crackles.The purpose of improving the quality of deep drawing parts can be achieved by changing the punch fillet size or chamfering to punch.If the blank dimensions are sufficient to meet the size of the drawing work piece,the smaller the blank dimension is,the better the quality of narrow drawing parts is.The more narrow the width of narrow pieces is and the deeper the drawing depth is,the easier it is to crack.关键词
