摘要
分析了轴对称变形时桥仓型毛边槽和楔型毛边槽毛边金属中应力的变化规律,并加以比较;提出了楔型毛边槽优于桥仓型毛边槽的观点。
The stress variations in the flash metal in wedge shaped groove and bridge-barn shaped groove in the axial symmetry strain state are analyzed respectively. It is concluded that wedge shaped groove is better than bridge-barn shaped groove for the metal flash.
