Paper Title:
The Effect of Bending Radius on Thickness Distribution in Hydroforming of Conical-Cylindrical Cups
  Abstract

Conical parts forming is one of the complex and difficult fields in sheet metal forming processes; because of the low contact area of the sheet with the punch in the initial stages of forming, too much tension is applied to the sheet causing bursting occurrence. Furthermore, since the major part of the sheet surface between the blank holder and punch tip is free, wrinkles appear on the wall of the drawn parts. Therefore, these parts are normally formed in the industry by spinning, explosive forming or multi-stage deep drawing processes. In this paper, the effect of punch tip radius and conical- cylindrical radius on formability and thickness distribution of the conical parts for three different punch angles were studied.
