Zusammenfassung:	PROBLEM TO BE SOLVED: To make an expansion of a rotary beam not inconveniently operative for guiding a piercing traverse by providing a draw-down outer face with a piercing traverse surrounding frame member or rotary beam side walls in a way that the smallest cross-section of the rotary beam is positioned at a side wall central area regarding the rotary beam length. SOLUTION: A direct pipe push out machine 1 mainly has a corresponding beam 2, a block accommodation part 3, a hollow press ram 4 and a mandrel 5 which passes through the press ram 4. The mandrel 5 is supported by a piercing traverse 6 connected with a piercing plunger 7 and a push out main plunger 8. The piercing traverse 6 is accommodated in a notch 9 of a frame-like rotary beam 10 and guided. A concave shape drawdown 11 like a circular arc broken line is formed on outside or periphery of the rotary beam 10 side walls 10a, 10b being remained at both sides of the notch 9.
