- Abstract
Deep drawing and hydroforming deep drawing (HDD) are the two conventional methods for production of cylindrical
cups. In this paper, two cylindrical workpieces have been produced with separated dies and the deformation force and
sheet thickness distributions have been compared. For increasing drawing ratio in the hydroforming deep drawing,
pressure chamber must be calculated and exerted properly. Limited tearing pressure curve have been obtained with
finite element simulation. By considering of this approach and conducting a series of hydroforming experiments, proper
pressure will be selected. Finally, workpiece was drawn with 2.3 drawing ratio by using proper pressure path. Results
have shown that although hydroforming deep drawing needs more forces, more drawing ratio can be achieved as a
result.
