Magnetic Medium-Assisted Inverse Bulge Pre-Forming and Deep Drawing Composite Forming Process for Improving Forming Performance of the Cylindrical Parts
Abstract:Due to the poor plasticity of aluminum alloy at room temperature, it is difficult to form thin-walled and complex curved parts. This paper proposes a composite method of inverse bulge pre-forming deep drawing based on intelligent magnetorheological (MR) fluid materials. Through the experiments and finite element modeling of cylindrical parts with drawing ratios of K1=2.125 and K2=2.25 were carried out under different forming conditions. The effect of soft mold medium on the drawing forming of cylindrical parts… Show more
