| 摘 要： | 汇场法已被证明是一种可行的理论方法。本文进一步研究了它对平面异形拉深零件外形的自动处理,绘出了自动绘制出的异形件毛料外形,用拉深实验检验了汇场法自动确定的几件典型零件毛料外形。在此基础上,提出了汇场法对设置拉深凸埂的指导作用,同时指出汇疡法确定毛料外形的精度可通过汇强的调整来改善。

| Abstract: | The Sink Field Method(SFM) has been shown to be an acceptable theoretical method for blank development. The autosegment of the outline of a irregular drawn part is investigated in detail in SFM. The blank contours of some irregular drawn parts are given, which are autotracked with the help of SFM computer program.The blank contours of some typical drawn parts autotracked by SFM are tested with drawing process. Based on the test results, guiding function of SFM for arranging drawing beads is discovered, and the accuracy of SFM for blank development is shown theoretically to be improved by adjusting the sink distribution. |
