Investigation of Formability of Metal Thin-Walled Tubes Based on the Tube Hydroforming

Tube hydroforming is one of the most popular forming technologies in achieving lightweight and integration of tubes and reducing wasting of resources. To better to study the technology, combined with the research progress of scholars at home and abroad, the formability of metal thin-walled tubes under hydraulic bulging is comprehensively and systematically discussed and summarized. In this paper, the forming process and formability of metal thin-walled tubes under spontaneous bulging, hydroforming with radical crushing and liquid impact forming are analyzed in detail, and the development prospects of various forming technologies are expounded respectively. Through the analysis and summary of the formability of tube hydroforming in recent years, it provides a useful reference for the development of tube hydroforming technology.
