介绍了采用旋拉新工艺成形加工管道的T形支管凸缘,给出简化的加工工艺尺寸参数计算公式,分析了旋拉设备主轴转速要求和进给量,以及采用温拉时加热温度的确定,最后分析了旋拉成形后T形支管凸缘处的金属性能。
This paper introduces the T - shaped branch flange which is formed by the new spinning process and gives a simplified calculation formula for the dimension parameters of the machining process. It also analyzes the spindle speed requirement and feed rate of the spinning machine and the determination of the heating temperature Finally, the metal properties of T-branch flanges after spin-forming were analyzed.
