Abstract:

A sort of new-style dieless drawing process titanium pipe shaped and the method of manufacture technology were introduced. The law of drawing speed was analyzed according to the deformation mechanism of titanium pipe dieless drawing. The mathematical model ofdieless drawing for titanium pipe has been set up, using calculus theory and titanium pipe geometry figure during dieless drawing and so on. It has been proved to true that the mathematical model is very simple, accurate, reliable, and practical through of experiment.
