Comparison and analysis of the stress distribute rule and deformation of two kinds of combination dies that with flat end plane or with oblique end plane cavity come to conclusion that the oblique end plane combination die is of higher intensity 摘要通过对平、斜端面组合凹模在预紧及合成两种状态下应力和变形位移的对比分析，得出了斜端面组合凹模的应力分布规律，指出在其他条件相同的情况下，斜端面组合凹模具有更高的强度。
