摘要
通过对胀形区成形极限图的理论分析和经验修正,建立了胀形区成形极限图的计算公式,经试验验证,在不同钢种、不同退火工艺、不同镀锌方式、不同表面处理方式下,按此公式计算的结果都能很好地符合试验结果。
Through the theoretical analysis and empirical correction to the bulging region of forming limit diagram (FLD), the calculating equation of bulging region of FLD is established.It is proved by the experiment that the calculating equation is corresponding to the experimental results very well under the conditions of different steel grades, annealing processes, galvanizing modes and surface treatment.
