前言为了生产难度较大的深拉延零件,并在拉延中得到大的拉延比(即小的拉延系数—译注),采用充液深拉延已带来了良好的效果。但由于设计模具和确定加工工艺参数在许多情况下需进行广泛的探索和试验,因而这种工艺方法的经济效果常常由此受到影响。为了减少这些工艺试验的费用,以便在经济上扩大充液深拉延工艺应用的可能性,我们首先提出了对 Introduction To produce deep-drawn parts that are more difficult to obtain and to obtain a large draw ratio during drawing (ie, a small draw coefficient), the use of deep drawing of the liquid has yielded good results. However, due to the extensive exploration and testing of molds and the determination of process parameters in many situations, the economic effects of this process are often affected. In order to reduce the cost of these process trials in order to economically expand the possibility of deep-drawing process applications, we first proposed
