Influence of blank-holder force on deep-drawing forming of conical parts

Open publisher page 1 citations

Abstract

The predominant failure modes in stamping of sheet metal parts are wrinkling and fracture.In general,these defects may be eliminated by appropriately manipulating the Blank-Holder Forces.In this paper,the numerical simulation of variable Blank-holder Force has been carried out with the aid of the Finite Element Method software DYNAFORM,and the best optimum load curve of Blank-holder Force of deep-drawing process of a conical part has been obtained.This paper also validates the simulation results by tests.It is demonstrated that the limit drawing height could be greatly improved when the variable BHF deep-drawing process was adapted.
