一前言拉深成形是利用模具使平面毛坯变成开口空心零件的冲压工艺。拉深延件的种类很多,由于其几何形状不同,因此,冲压过程中变形区的位置、变形的性质、变形的分布,毛坯各部位的压力状态和分布规律等都有相当大的差别。所以在确定工艺参数,工序数与顺序,以及模具的设计原则和方法等都必须区别对待。笔者在设计纺织工业中常用的多臂装置油盘(图1)的拉深模时,将确定斜壁匣形件各 A preface Deep drawing is the stamping process that uses a mold to turn a flat blank into a hollow part of an opening. Because of its different geometric shapes, there are quite a few differences in the location of the deformation zone during stamping, the nature of the deformation, the distribution of the deformation, the pressure state and the distribution of the various parts of the blank. So in determining the process parameters, the number of processes and order, as well as mold design principles and methods must be treated differently. The author in the design of the textile industry commonly used multi-arm device tray (Figure 1) of the drawing mold, will determine the inclined wall box pieces
