摘要
基于对中厚板冲孔横断面特征的分析,通过分析现有文献中的进展,提出了衡量冲孔形状质量的公式,采用实验研究与数值模拟相结合的方法,分析了隙径比、相对间隙、压边圈对冲孔形状质量的影响规律,可为提高冲孔质量提供依据。
Through the analysis of the data of the existing literature results that based on the analysis of the cross-sectional characteristics of plate punching, thin paper raised the formula that measure the precision punching quality shape by adopting the combination of experimental study and numerical simulation method. Analyzed the influence law of the gap ratio, relative gap, the blank holder to the cross section quality. This research can provide guidance for improving quality of punching.
