摘要
为解决AutoForm拉延筋截面参数在3D软件设计中无法直接使用的问题,推算了在3D软件中可以直接使用的Z向拉延筋截面参数求解公式,主要有流入、流出侧Z向立面与拉延筋中心线的距离、凸筋圆角、凹筋圆角。使用CATIA软件设计的拉延筋与AutoForm自动生成的拉延筋进行模拟对比,得到了理想的验证结果,其中筋宽误差和筋高误差均控制在小于0.05 mm,拉延流入量误差控制在小于1 mm。
In order to solve the problem that the cross-sectional parameters of AutoForm drawbead could not be directly used in 3D software design,this paper derived solution formula for the cross-sectional parameters of Zdirection drawbead that could be directly used in 3D software,mainly including the distance between the Z-direction elevation on the inflow and outflow sides and the centerline of the drawbead,convex fillets,and concave fillets.The drawbead designed using CATIA software was compared with the drawbead automatically generated by AutoForm,which yielded ideal validation results,with both the width and height errors controlled within the range of 0.05mm,and the draw-in error was controlled in 1 millimeter.
