Abstract

The deep drawing process of square and rectangular shells were investigated under different process conditions, and using two different drawing quality steels. The main objective was to identify the significance of some of the process parameters on the outcome of the drawing operation. The process parameters examined were shape and size of blank, the blank-holder force and frictional condition between blank and tooling. The results of this investigation were presented in terms of punch load, through thickness and in-plane strain distributions, formations of flange wrinkles and fracture, and the largest possible blank size that can be drawn successfully. Some of these experimental results were used to verify the validity of a simplified analytical model which was described in the first part of this paper.
