Advance in high speed forming technology

High speed forming technology,including explosive forming,electromagnetic forming and electrohydraulic forming,has the advantage of large forming force,short forming time and simple forming device,therefore it can be used for the process of the high strength and low forming metal material at room temperature.The principle and application of high speed forming technology are introduced.The hybrid forming process combined the high speed forming technology and quasi-static pressure hydroforming was analyzed on the forming efficiency and formability of high speed forming.The hybrid forming process effectively improving the forming efficiency and formability,and the effect of high speed forming conditions on the material formability are discussed.
