端部带有马鞍型坡口的短直段空间弯管制造工艺研究

Study on the Manufacturing Process of Short Straight Space Elbow with Saddle Groove at the End

本文通过对某项目端部带有马鞍型坡口的短直段空间弯管的制造工艺方案进行剖析,对该空间弯管的结构特点和加工设备进行了简要介绍,并对其在生产过程中所采用常规工艺方法的限制进行分析,进行了相关的工艺试验,针对在试验过程中由于该空间弯管的端部直段过短而引起坡口变形、后移等问题进行逐一分析,并制定专项工艺措施,并着重介绍了空间弯管的制造工艺研究过程。

In this paper,the manufacturing process of short straight space bend with saddle groove in the end is analyzed.The structure characteristics and machining equipment of the space elbow are briefly introduced,and the limitations of the conventional technological methods used in the production process are analyzed,and relevant technological tests are carried out.In this paper,the problems of groove deformation and backward movement caused by the shout end of the straight section of the space elbow are analyzed,and special technological measures are formulated,and the manufacturing process of space elbow is emphatically introduced.
