Abstract
The numerical control (NC) heat bending of thin-walled Ti-alloy tube with large diameter and small bending radius with Ф50×1×R75mm (diameter OD bending radius CLR) is explored by 3D-FE thermal-mechanical coupling simulation of heat conducting and NC bending. The results show that: (1) The heating of both pressure die and mandrel is proved to be appropriate to obtain the required temperature field. (2) In terms of wall thickness variation, wrinkling and cross-section deformation, the optimum span of the key parameters are obtained: the bending velocity of 0.4rad/s, the matched pressure die speed of 80%-110%, and temperature of 600-800°C.
