Abstract

Accoding to the geometry of semicircular drawbead and the mechanics characteristic of the blank during drawing cone part with drawbead, the maximum blankholder force for avoid inner-buckle are critically calculated. And the influence of processing parameters of drawbead on the critical blankholder force are studied. Then increasing radius of the drawbead, the resistance of drawbead decrease so that the critical blankholder force increase and the reasonable range of blankholder force enlarge, and the critical blankholder force decrease with increase of drawbead hightness so that the reasonable range of blankholder force lessen.
