Numerical Simulation and Experiment of Aluminum Sheet Metal Springback in New Quenching State

Abstract:

2024-T3 aluminium sheet metal rubber forming process after quenching is studied. The tensile properties of 2024-T3 after quenching are measured. It is found that the yield strength and ultimate tensile strength are reduced, whilst total elongation value is increased. Springback character of rubber forming is studied by numerical method and springback compensation of rib flanging is studied. The simulation is compared with experiment. It is found that the tool shape considering springback is got using numerical method. The parts after springback achieve the design accuracy. So the method can be used in the application of rubber net forming.
