摘　　要：针对减震器孔加工中生产节拍高、尺寸公差、位置精度要求高等特点,设计出双套导向结构的气、液相结合冲孔机构,并采用ANSYS/LS-DYNA对冲孔全过程进行数值模拟,得到工件隆起处最大位移和冲裁力与冲头进给速度的关系曲线,在节能、高效的前提下,合理确定了冲孔加工的冲头进给速度、确切的冲裁力等主要技术参数。Aimed at the processing of the shock absorber＇s hole that has the characteristics of high requirement like high production rhythm,dimensional tolerance and positional accuracy and so on,a gas-liquid combination punching mechanism with two different guide structures is designed. Numerical simulation of the whole punching process was proced with ANSYS /LS-DYNA,by which the relationship curve of the maximal displacement of workpiece＇s bump with the blanking force and the feed speed of punch was obtained.Under the premise of high efficiency and energy saving,the feed speed of punch,exact blanking force and other main technical parameters are confirmed reasonably.
