摘要：

大型压力容器的使用场合广泛、成形工艺种类多、制造难度很高，因而一直是研究的热点。从整体成形（其中包括热冲压工艺、旋压技术、爆炸成形、模具旋转锻造法等）、分瓣成形（拼焊成形）工艺等方面对压力容器的封头在制造过程中的国内现状、工艺和特点进行了系统介绍；此外，对各成形技术生产过程中质量控制的关键技术进行了简单概述，针对几种典型成形工艺出现的起皱、裂纹等成形缺陷原因进行分析，并归纳一些主要控制措施，最后总结了各成形工艺的研究现状与加工特点。

The large pressure vessel has always been a research hotspot due to its wide use, multitudinous forming technology and high manufacturing difficulty. The research status in China, including manufacturing processes and their characteristics on heavy pressure vessel thick-wall sealing head were systematically introduced from the aspects of the overall forming technologies including hot stamping, spinning technology, explosive forming and rotating die forging method, etc. and split forming technology(welding forming). In addition, the key technologies of forming processes in quality control were outlined briefly. Meanwhile, the causes of forming defects such as wrinkling, cracking produced by several typical forming process were analyzed,and some of the major control measures were deduced. Finally, the research status of each forming process and processing characteristics was summarized.
