摘要

Rigid mandrel plays an important role in restricting the cross-sectional deformation of double-ridged rectangular tube in rotary draw bending. So a 3D FE model of H-typed rotary draw bending of the tube was established, and the influence law of rigid mandrel parameters on cross-sectional deformation was obtained. With the increase of core number, the deformation of different parts of tube decreases. When core number exceeds 3, the effect of increasing the core on the improvement of cross sectional deformation is insignificant. A curved mandrel with simple structure was proposed, and the effect of curved mandrel on controlling of cross-sectional deformation is better than that of separated rigid mandrel.
