    摘要:

    通過有限元模擬2198鋁鋰合金斜面筒形件的充液拉深過程,結(jié)合實驗對其塑性變形規(guī)律進(jìn)行研究。研究結(jié)果表明：在板料充液拉深過程中,合適的液池溢流壓力是關(guān)系到充液拉深能否成功；壓邊間隙影響零件的減薄率；合適的預(yù)脹壓力可減小零件厚度減薄率,能夠獲得壁厚相對均勻,成形質(zhì)量較好的零件。

    Abstract:

    In this research, the process of hydrodynamic deep drawing of Al2198 was investigated by using finite element simulation experimental works. And the effects of die cavity pressure, blank holder gap and pre-bulging pressure on the forming process and the thickness distribution were analyzed. The research indicated that the pressure inside the liquid chamber and the blank holder gap or blank holder force were the main factors affecting hydrodynamic deep drawing process. And appropriate pre-bulging pressure was beneficial to form a good quality parts with a relatively uniform wall thickness.
