摘　　要：以轻量化和一体化为特征开发出来的管材内高压成形技术,由于在空心变截面轻体构件制造方面无可替代的优势,在国外科研机构和大型企业里受到广泛关注和应用。但因其设备比较昂贵,这项技术在我国的发展遇到一些困难。本文在系统研究管材内高压成形工艺的基础上,结合实际情况,自主开发了一套管材内高压成形设备,并对实践过程中遇到的一些问题,如模具的设计与优化、管材端口的密封形式以及高压的实现与控制等进行了研究,得到较好的结果。在实际应用中,设备运行情况良好,可以满足管材内高压成形实验的要求。A suit of tube hydroforming equipment has been independently developed combining the mater of fact on the basis of systemical investigation in tube hydroforming process in the text.Some problems encountered in the practice such as die design and optimization, end sealing style, realization and control of high pressure etc.have been studied, and the research findings have been applied into practice. The results show that the system works well which can meet the demand of tube hydroforming experiments.
