摘要:
摘要:在冲压拉延过程中为了减少汽车覆盖件产生起皱和破裂等缺陷,针对材料为AA6009铝合金的车门内板,运用有限元软件DYNAFORM进行拉深成形数值模拟和工艺优化。采用设置板料压边力,摩擦系数以及拉延筋的方法,以内板的成形极限图(FLD)和壁厚分布图为衡量标准,对成形缺陷产生的原因进行预测和优化,得到最佳加载方式。然后运用三维造型软件UG进行了汽车内板的凸、凹模和压边圈的设计并进行了模具零部件的设计,完成了模具装配与校核。结果表JP2〗明,在凹模上设置拉延筋并且设置合理的压边力和摩擦系数,可以有效地提高工件的成形质量,防止起皱和破裂的产生,最后运用UG进行三维零件的绘制与装配,减少了模具研发的时间与试模周期。

Abstract:In the drawing process in order to reduce automobile wrinkling and rupture defect, In view of the material for the AA6009 aluminum alloy door inner plate, using the finite element software DYNAFORM to carry on the drawing forming numerical simulation and the craft optimization By setting the sheet blank holder force, drawbead and friction coefficient method, the forming limit diagram (FLD) and the wall thickness distribution of the plate are measured as the standard, prediction and optimization of the cause of forming defects, get the best loading Then use the threedimensional modeling software UG to carry on the automobile interior board convex, concave die and the blank holder design and carried on the mold component design, completed the mold assembly and the check The result show that set draw bead on die and effective binder force and proper coefficient of friction may reduce the tendency of wrinkling and improve the quality of stamping product Finally, the use of UG for threedimensional parts of the drawing and assembly, reduce the time of mold development and test mode cycle
