摘要
研究了轴对称拉伸各向异性材料的过程。从圆柱形零件的凸缘上和壁上的允许变形出发 ,获得了极限拉伸程度的计算公式。确定了极限拉伸程度与齿槽形成特性和零件周边壁厚差特性间的关系。
The process of axisymmetric drawing of anisotropic materials is considered. The formulas for calculating top limitation of drawing originated from the deformation limits on the flange and the wall of cylindrical articles are developed. The relationship between drawing top limitation and characteristics of scallop formation and thickness irregularity along article perimeter is found.
