摘　　要：基于分块压边液压成形装置,运用Dynaform有限元软件对AZ31B镁合金方形件的液压成形过程进行了数值模拟。比较分析了镁合金板在整体式压边和分块式压边条件下的液压成形效果,重点研究了分块压边方式对镁合金方形件的壁厚影响规律,并探索了相对合理的压边力参数。研究结果表明:与整体式压边相比,采用分块式压边能有效改善AZ31B镁合金方形件的壁厚均匀性,提高其成形质量。Based on hydraulic drawing device with segmental blank holder,the forming process of AZ31B magnesium alloy square parts in hydraulic deep drawing was simulated using the commercial FE software Dynaform. The forming effects of magnesium alloy sheet under unitary blank holder and segmented blank holder were analyzed. The influence of segmental blank holder on the thickness of the square parts was investigated systematically and the parameters of blank holder force were explored. The results show that com-pared with unitary blank holder,the wall thickness uniformity and forming quality of AZ31B magnesium alloy square parts can be obvi-ously improved under segmented blank holder in hydraulic deep drawing at room temperature.
