Abstract：

Combining numerical simulation and physical experiments, the special-shaped incremental hole flanging in tube wall with different hole shapes and different flanging directions on the round tube and square tube blanks was realized. Then, it was verified by simulation that the force situation in the special-shaped incremental hole flanging process of round tube wall was different from that of the square tube, and the forming force of each part was about the same. Furthermore, in the square tube, there was a relationship of forming force at the arc end > forming force at the transition > forming force at the straight wall. The research results show that the cracks, the metal accumulation, the serious scratches, the protruding bottom, etc. are the types of defects that may occur in the incremental hole flanging, and the related defects are controlled by reducing the feeding amount, optimizing the trajectory, increasing the pre-flanging amount and increasing lubrication. In addition, due to the different deformation methods, the forming force in the special-shaped incremental hole flanging of square tube is greater than that of round tube, and the thickness distribution in the special-shaped incremental hole flanging of round tube is not as uniform as that of square tube, but the thickness distribution law is gradually decreased with the increasing of the height of flanging hole.
