Effect of the Location of Draw Bead and Its Profile in Cylindrical Cup Forming

Abstract

The effect of draw bead on the production of cylindrical cup in deep drawing process three metal (aluminum, brass, steel). The draw bead is designed by Bezier curve’s equation that play an important role in prevent occurrence of wrinkling especially with improved aluminum, because that’s only lubricant is passed with aluminum, when compared it with without draw bead, it is noticed that the maximum drawing force will increase due to lubricant. It can be concluded that in deep drawing with draw bead the wax has used us a lubricant, be better compared to without draw bead for AL, good agreement is evident between ANSYS(18) and experimental work. comparing between deep drawing with draw bead and without the energy required to complete drawn when using draw bead is more than without draw bead, The aims of this paper to predict the wrinkling and thinning (necking) and to study the influence of using draw bead on the thickness distribution along the cup, so the hoop strain distribution along the blank is more uniform for using draw bead and thickness strain with & without using draw bead, is about 0.17% in thinning for brass with it and 0.20% in thickening to steel without it.
