| 摘 要： | 飞轮盘为大尺寸、变壁厚零件,采用先切割后焊接组装的加工方式,工序多,周期长,成本较高.采用冲锻成形新工艺成形该零件,并借助有限元模拟软件DEFORM-2D,对成形过程和模具关键尺寸进行了优化分析.为成形零件R5 mm内圆角,采用两步成形,即预成形时采用大半径圆角凸模拉深并利用镦粗凸模镦粗侧壁,终成形时将拉深凸模换为R5 mm圆角的凸模并将零件镦粗到要求尺寸.优化后的模拟结果显示成形良好,为实际生产提供了一定的参考依据.

| Abstract: | Flywheel panel is a part of large size and variable wall thickness.If the traditional process,such as cutting and weld-assembling is used,it demands more procedures,takes longer period and costs more.This research adopted a new stamping-forging process.The forming process and key mold dimensions were optimized utilizing DEFORM-2D.In order to shape the inner fillet of R5mm,a forming process with two-step was designed.A drawing-punch with bigger fillet drew the billet and an upsetting-punch compressed the wal... |
