基于CAE技术驱动的汽车前门外板覆盖件拉延模设计

Design of drawing die for the automobile front door panel based on CAE technology driven

汽车覆盖件拉延模具设计,如果缺乏必要的设计软件做拉延工艺分析,模具设计往往存在一些不足,要么拉裂,要么起皱,影响模具的质量。基于CAE技术驱动的覆盖件拉延模具设计,以某型汽车前门外板拉延成型为研究对象,导入Dynaform和UG软件进行拉延工艺补充设计和分析计算,确定拉深方向,获得可靠的拉深工艺方案,确保工件在拉延过程中顺利成形,提高了拉深模具结构设计的可靠性,为汽车覆盖件拉延模具设计提供有益的参考。

For the design of automobile panel drawing it affects the quality of the mold if there is die, it often has some deficiencies, or cracking, or wrinkle, a lack of necessary design software for the drawing process a- nalysis. The design of drawing die for the automobile panel based on CAE technology driven, taking the ble drawing process, so that to ensure the workpiece forming conveniently in drawing process. So the re- liability of drawing die structure design is improved. panel drawing die designs. It can provide a useful reference for the automobile
