针对铝合金板材成形性差的特点，提出液体内向流动动态充液拉深新技术。采用铝合金2A12-O板材对成形过程进行了初步实验验证后，运用有限元方法探讨不同的径向压力和不同的预胀路线对成形零件壁厚分布的影响。结果表明，采用该方法可以显著提高铝合金2A12-O的成形极限，成功拉深出拉深比达2.85的杯形件；径向压力显著影响杯形件壁厚的分布，通常较大的径向压力下的壁厚也较大。
A new method, named hydrodynamic deep drawing with radially inward flowing liquid, was proposed, aiming at the poor formability of aluminium alloy sheet. After a preliminary experimental validation of the proposed method by using 2A12-O aluminum alloy, the effects of different radial pressures and different pre-bulging loading paths on the wall thickness distribution of the formed cups were investigated with the assistance of FEM. The results show that the foming limit of 2A12-O aluminum alloy is obviously improved by the method, and a cup with a drawing ratio of 2.85 is formed successfully. The radial pressure during the deep drawing process has a great influence on the wall thickness distribution of the formed cups. In general, the higher the radial pressure, the thicker the wall thickness.
