Title: Hydromechanical Deep Drawing with Uniform Pressure on the Flange
Abstract: Conventional hydromechanical deep drawing is difficult to simulate due to difficulties regarding the determination of the pressure distribution on the flange when a leak flow occurs between the draw die and the flange. To avoid this problem the hydromechanical deep drawing process has been modified in such a way, that the pressure on the flange is uniform throughout the deep drawing. The uniform pressure on the flange makes it easy to simulate the modified hydromechanical deep drawing process. The modified hydromechnical deep drawing process has been investigated experimentally and the experiments show that the concept works in practice; cylindrical cups made from aluminium have been drawn successfully with a drawing ratio as high as 3.0. The paper presents the modified hydromechanical deep drawing process and experimental results obtained are compared to results obtained using FEM.
