METHOD AND APPARATUS FOR CONTINUOUSLY MAKING TUBE ELBOWS Russian patent published in 1997 - IPC

Abstract RU 2098207 C1

FIELD: machine engineering, particularly method and apparatus for producing tube elbows by drawing through bent portion of mandrel. SUBSTANCE: novelty is fixation of working position of mandrel according to its bent portion and use of power mechanisms for clamping and holding mandrel by means of flat wedge clamps. Mandrel is returned to its working position due to axial motion of power mechanisms. EFFECT: enhanced efficiency, lowered energy consumption, high quality of products, simplified design of apparatus. 2 cl, 4 dwg
