摘　　要：为了解决镁合金板常温下难成形的问题,采用液体介质加热进行了AZ31B镁合金的单点渐进成形实验。并通过改变实验参数对方锥件出现的侧壁鼓凸现象进行了分析。结果表明:液体介质加热的方法可以实现镁合金板料的渐进成形,改变加工参数能够实现对侧壁鼓凸高度的控制。In order to solve the problem of difficult forming of magnesium alloy sheet at room temperature, the single point incremental forming of AZ31B magnesium alloy was carried out by liquid medium heating. In addition, the side wall drum bulging phenomenon of the square taper parts was analyzed by changing the experimental parameters. The results show that the method of liquid medium heating can realize the incremental forming of magnesium alloy sheet, and changing the processing parameters can control the height of the side wall drum bulging convex.
