Abstract

Abstract:

In order to restrain the buckling defects of the thin aluminum alloy plate parts after the process of rubber bladder forming, the buckling process is theoretically analyzed using thin plate buckling differential equations, and the effects of natural aging time and forming pressure on buckling defects are studied through the rubber bladder forming experiment. The results show that the flange buckling wave number has the relationship with the diameter ratio, and the forming experiment results with different flange widths show that the flange wave number agrees with the theoretical calculated results, the buckling defect height increases with the increase of the natural aging time, and decreases with the increase of the forming pressure. Therefore, the results of the theoretical analysis is valid, and the buckling defects can be restrained by reducing forming time after quenching and increasing forming pressure.

Key words: aluminum alloys, thin plate, rubber bladder forming, flange buckling, aging time, buckling wave number
