| 摘 要： | 研究厚度小于0.3mm的薄金属板的微胀形性能,为了得到胀形过程中薄板的成形性能规律,分别采用三种厚度的铜板和四种厚度的铝板进行胀形实验.结果表明:不同厚度的金属板的胀形深度不同,随着板厚的降低,铜板及铝板变形后的最大应变及极限胀形高度有增高的趋势.

| Abstract: | The micro-bulging capability of thin sheet metals below 0.3 mm thick ness is studied. The thickness of sheet metal is chosen to be an important e xperimental parameter. In order to obtain the formability laws of sheet metals d uring the bulging process, sheet coppers and sheet aluminums with different thic kness are used.After the bulging the re are different depth for sheet metal of different thickness.The result shows that with the decreasing of the sheet metal thickness,the largest stress a nd limit bulging height of the metals after deformation tends to increase. |
