This paper presents a improving method in a press forming for transferring convex shapes of an inner plug projection onto the tube-inner surface by applying outer-die ironing from the tube-outer surface. The previous study found that the concave shape was not perfectly formed and some “Non-filled-area” appeared around the upper and lower parts of the plug projection. This study tried to verify the effect of applying the reaction force on the tube-end surface by the finite element analysis (FEA) and experiment. The FEA showed the suitable amount of the reaction force and the optimum timing for reducing the force. The analytical results were verified by the experiment and the “Non-filled-area” was successfully reduced by the proposed method.
