Abstract
5A06 aluminum alloy exhibits low density, high strength, and excellent corrosion resistance, which is widely used in areas of the aerospace, aviation, missile, ship and other fields. However, the defects, such as springback and thinning will occur during the process of stamping. In this research, the formability of 5A06 aluminum alloy thin-walled elbow is studied by experiments and FE simulation. Thinning and springback of 5A06 aluminum alloy thin-walled elbow is analyzed when the BHF is 10 kN, 15 kN and 20 kN, and the friction coefficient is 0.15 and 0.3, respectively. The result shows that the maximum thinning rate increases with increasing of BHF and friction coefficient. Thinning occurs on the short edge and reaches the maximum value around the curved edge. When BHF and friction coefficient are 10 kN and 0.15, respectively, the maximum thinning rate is 5.22%. A large BHF contributes to control springback. When BHF is 20 kN, the maximum springback is 3.01 mm. The simulation results exhibit good consistency with the experiment results.
