Abstract

Abstract: In recent years, hydroforming process has been applied in different industries such as aerospace, automotive industry and military industry due to its advantages, like high dimensional accuracy, capability of forming complicated-shaped parts and high drawing ratio. Hydrodynamic deep drawing with radial pressure is one of the hydroforming processes. In this paper, forming of cylindrical cups in hydrodynamic deep drawing with radial pressure is investigated and the effect of pressure path on the cup thickness distribution and punch force was studied. In this study, two pressure paths (liner pressure with maximum pressure and step pressure) were used and their thickness distributions were compared. The results of this study have shown that by choosing the step pressure path, the quality of the formed cup increases and more uniform thickness distribution will be obtained.
