【摘要】 定量分析了穿孔轧制力和顶头轴向力对毛管壁厚及其横向均匀性的影响。分析表明 ,轧制力对穿孔毛管壁厚的影响是显著的 ,而对其横向壁厚均匀性的影响是微小的 ;在大倾角条件下 ,顶头轴向力对毛管壁厚及其均匀性的影响都很显著。更多还原

【Abstract】 The influences of the separating force and axial force of the piercing point bar on the wall thickness of the shell pierced,and on its lateral uniformity are analyzed quantitatively.The effect of the separating force on the wall thickness is notable,but that on its lateral uniformity may be neglected.The effects of the axial force of the point bar,both on the wall thickness of the pierced shell and its uniformity,are all notable under high cross angles.更多还原
