摆辗是局部加载非对称连续不均匀变形,其成形规律对于不同类型的零件来说是很复杂的。而圆柱件摆辗则是最基本的摆辗成形工艺。对其摆辗变形规律的研究是认识各类复杂摆辗件变形规律的基础。一、摆辗自由镦粗圆柱体变形特征圆柱形工件摆辗变形特征与工件每转进给量S的大小、毛坯的初始高径比H_0/D_0及模具与工件间的接触润滑状态和变形程度
Roller is partial load asymmetric continuous uneven deformation, the forming rules for different types of parts is very complicated. The cylindrical roller swing is the most basic swing forming process. The study of the law of its swinging and rolling deformation is the basis for understanding the deformation rules of all kinds of complex swinging parts. First, the free rolling upset cylinder deformation characteristics Cylindrical workpiece swinging deformation characteristics and workpiece per revolution S size, the initial height ratio of blank H_0 / D_0 and contact between the mold and the workpiece lubrication state and the degree of deformation
