The rotary draw bending process of the double-ridged rectangular tube is a complex nonlinear physical process with the internal and external die constraints. The stresses of the tubes under different die constraint conditions are different, which changes the situation of the cross-sectional deformation. And the deformation affects the quality and usability of double-ridged rectangular bending tube seriously. Then, based on the FE platform of ABAQUS/Explicit, the 3D-FE model is established for E-typed rotary draw bending of H96 brass double-ridged rectangular tube and validated by the experiment. Using the model, the influence of the internal and external die constraint conditions on cross-sectional deformation of the double-ridged rectangular tube in E-typed rotary draw bending process is researched. The results show that only when the inner ridge groove is constrained, the inner ridge groove shrinkage deformation can be better controlled, but other deformation is larger. Only when the outer ridge groove is constrained, the inner ridge groove width deformation does not change basically, but other deformation is smaller. When the inner and outer ridge grooves are both constrained, the cross-sectional deformation can be controlled effectively. The number of cores has more significant effect on the cross-sectional deformation, including the height and width of the global tube, the outer ridge groove width and the two ridge grooves spacing deformation, but has no significant impact on the width deformation of inner ridge groove.
