摘要
大型厚壁封头拉深成形相较旋转展压成形具有锻态组织更加均匀,制造周期短,节省材料的优点。分别对大型厚壁等壁厚封头及带整体支撑裙座的异形厚壁封头的拉深成形进行了分析,阐述了两类封头拉深成形中的关键问题及工艺方案,对实际应用具有较强的指导作用。
Compared with rotary expansion forming,large thick-walled head drawing forming has the advantages of more uniform forging structure,short manufacturing period and saving material.In this paper,the forming of equal wall head with large thick wall and special shaped thick wall head with integral supporting skirt have been analyzed,and the key problems and technological schemes in the drawing forming of two kinds of heads have been expounded,which has a strong guiding effect on practical application.
