摘要:

由于结构封闭、型面复杂,不等高曲面法兰盒形件成形非常困难,常会发生开裂。采用有限元软件PAMSTAMP基于拉格朗日的弹塑性本构方程,建立有限元模型来分析不等高凸法兰盒形件的成形过程,摸索和确定出展开毛坯、多道次模具结构、压边力等诸多影响因素的最佳数值,研究出一套行之有效的成形方法,为此类相似零件的后续生产开辟了一条崭新的成形思路。

Rectangular box, due to its self-enclosed structure and complex moulding surfaces, is very hard to use the existing precision forming technologies, which breeds certain risks in production. FEM model using PAMSTAMP was established based on Lagrange's dynamic constitutive equation to analyze the forming process of rectangular box with convex flange. A series of optimal values were explored and developed in terms of blank spreading, multi-steps die structure and blank-holder force. An effective set of forming method was built. It leads to pioneering a novel way of forming for the successive production of similar parts.
