Abstract

Deep drawing process, one of sheet metal forming methods, is very useful in industrial field because of its efficiency. The production of optimal products using this process is dependent on the process variables such as blank shapes, profile radii of punch and die, and formability of materials. Of the variables, the blank shape is very important since it controls the formability factor. This paper reports the investigations on three kinds of blank shapes and the scribed circle test on three deformation modes. The punch load distribution for elliptical forming processes were measured under different conditions of profile radii of punch and die and discussed here. These experiments clarified the influence of the profile radii of the punch and die and the blank shape on the punch-load distribution for the elliptical deep drawing product of automobile parts. The aim of this study is to investigate the effect that the process variables have on drawability in a non-axisymmetric elliptical deep-drawing process and to obtain useful data from the industrial field.
