TUBE BENDING APPARATUS Russian patent published in 1995 - IPC

Abstract RU 2044585 C1

FIELD: production of bent tubes used in heat engineering. SUBSTANCE: apparatus has stem 5 of hydraulic cylinder 4. During working stroke of stem 5 plunger 7 abuts against bottom of hydraulic cylinder 6. It results in clamping of billet. Clamping jaw ejecting force developed in the process of bending is taken up in bending plane through levers 9 and 10 and plunger 7. EFFECT: increased efficiency, high quality of bent tubes and enhanced reliability in operation. 2 dwg
