Zusammenfassung:	PURPOSE: A tube push out press is provided 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. CONSTITUTION: A direct pipe push out machine(1) mainly has a corresponding beam(2), a block accommodation part(3), a hollow press stamp(4) and an opening sleeve(5) which passes through the press stamp(4). The opening sleeve(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) remaining at both sides of the notch(9). 튜브 사출 프레스는, 중공의 프레스 스탬프를 지지하는 이송 빔이 홀더와 가이드 방향으로 이동하고 프레스 스탬프를 통과하는 구멍 슬리브를 지지하는 이송장치가 결합 피스톤위에서 서로 프레임을 형성하여, 구동 빔과 함께 메인 프레스 피스톤을 이루며, 이송 빔의 신장이 이송장치의 안내를 방해하지 않으며, 이송장치를 둘러싼 프레임 부품 또는 이송 빔 턱과 결합 형성된 외부면을 나타내고, 이송 빔 길이 방향에서 이송 빔의 최소 단면을 턱 중앙부에 위치시키는 특징을 갖는다.
