本文分析了正旋压极薄壁圆筒时的金属塑性流动情况及受力状态;指出了造成金属堆积、局部失稳、工件产生皱折和螺旋波纹的原因;阐述了张力旋压的工艺方法,并给出了坯料尺寸及典型工艺过程;较详细地介绍了用于张力旋压的专用旋压机。为强力旋压高精度极薄壁管材提供了一种可行的工艺方法及张力旋压机的设计方案。 This paper analyzes the metal plastic flow and force state when the thin-walled cylinder is being spun and points out the causes of the metal accumulation, local instability, the crease and spiral corrugation of the workpiece, and expounds the technological process of tension spinning The blank size and typical process are given. The spinning machine for tension spinning is introduced in detail. It provides a feasible process method and the design scheme of tension spinning machine for the strong spinning high precision thin-walled pipe.
