Abstract：

The forming process of 2024-T3 aluminium sheet metal under new quenching state was studied.The tensile properties of 2024-T3 after quenching were measured.It is found that the yield strength and ultimate tensile strength are reduced,while total elongation value is increased.Springback character of rubber forming was studied by numerical method and springback compensation of rib flanging was analyzed.The simulation was compared with experiment.The tool shape is got using numerical method in consideration of sprinback.The part design accuracy after springback was achieved.So the method can be put into practice..
