超塑成形中以鈑材气压吹塑成形研究最多,现已开始生产应用。鈑材吹塑成形主要特点之一是利用材料变薄来延展面积,填充模具型腔成形的。研究各种超塑成形件的变薄规律,对合理设计超塑成形件、控制超塑成形参数及超塑成形模具结构的设计有着指导性的意义。 Superplastic forming sheet metal pressure blow molding up to now, has now begun to produce applications. One of the main features of sheet metal blow molding is the use of material thinning to extend the area, filling the mold cavity forming. Studying the law of thinning of all kinds of superplastic formed parts is of instructive significance for the design of superplastic formed parts, control of superplastic forming parameters and the design of superplastic forming mold.
