摘　　要：为了探究合适的数控渐进成形工艺参数范围,确定更优的敲击式渐进成形性能方案,通过单因素试验法研究振幅、频率、工具头直径和层进给量4个因素对AA2024铝合金板料成形性能的影响规律。试验结果表明:与传统的增量成形方式相比,敲击式渐进成形方式会降低板料的成形极限角,板料的成形性能会有所降低;当振幅为5 mm时,成形极限角随着频率的增大而增大;当振幅为10 mm时,成形极限角随着频率的增大而减小,成形随层进给量增大而增大,随层工具头直径增大先减小后增大。In order to explore the appropriate range of NC incremental forming process parameters and determine the better percussion incremental forming performance scheme,by single factor test method,explores the influence of amplitude,frequency,tool head diameter and layer feed on pageon AA2024 aluminum alloy sheet metal forming performance.The experimental results show that compared with the traditional incremental forming method,the percussive incremental forming method can reduce the forming limit angle and the forming property of the sheet metal.When the amplitude is 5 mm,the forming limit angle increases with the increase of frequency.When the amplitude is 10 mm,the forming limit angle decreases with the increase of frequency,the forming increases with the increase of layer feed,and decreases first and then increases with the increase of layer tool head diameter.
