Aiming at the technical challenge of spinning forming used for ultra long tubular parts, a new spinning technology based on floating die and synchronous rotation of both ends of the spinning blank was put forward. That is die ring spinning, which is divided into die ring forward spinning and die ring backward spinning. The die ring spinning utilizes to improve the stress condition of deformed metal parts and enhances the fluidity of crystal phase structure along the slip surface. It can not only eliminate the phenomenon of material bulging before spinning wheels, but also improve the straightness and reduce the ellipticity of pipes at the same time.
