Study of Spinning Processing Technology of a Seamless Cylindrical Titanium Liner

Abstract:

Through proposing creatively the process scheme of designing reverse spinning trajectories and polishing internal surface by pressure aimed at seanless cylinder Ti-liners of necking spinning, it is manufactured successfully that the head plates of Ti-liner can meet design demands besides internal and exterior moulding surface, and the wall thickness of Ti-liner is 0.6 mm whose internal surface has not deeper ruck, especially smooth in the location of R angle. And it is elaborated detailedly that the processing parameters of spinning such as the designed and actual process of spinning mode、spinning passes、spinning temperature and so on. The results of this article can resolve the trouble of welding seam for gas cylinders and liners chronically, and the reliability of production has been improved dramatically during service period.
