|
In intelligent control of rectangular box deep drawing,the wrinkling theory should be recognized in order to avoid flange wrinkling.In this way,the occurrence of winkle can be controlled.In this paper,the criterion of flange wrinkling is set up and the predictive method of flange wrinkling is improved based on C-B rule.Finally the way to get the curve between critical stroke and blank holder force is lay out which will give the farther support to predict the flange wrinkling in real time.
