Development of Drawbead Expert Models for Finite Element Analysis of Sheet Metal Forming Process (Part1: Experiment)
초록
During sheet metal forming on a double-action press, drawbeads on the blankholder supply a restraining force which controls the flow of metal into the die. The sheet formability can be improved by the optimum drawbeads installation when the punch enters into the die opening. Experiments on the various drawbeads, circular, step, double circular, and circular-step drawbead, have been performed under various working conditions.
