FIELD: plastic metal working, namely manufacture of multielbow shaped parts from elongated blanks. SUBSTANCE: apparatus includes mounted on base: mandrel and bending lever having sleeve mounted on axle and rod with handle rigidly secured to sleeve; guiding liners. There are mounting opening in base for pin limiting blank motion and for pin limiting rotation angle of bending lever. In lower part of sleeve there is segment-shaped groove. Axle of bending lever is mounted in base with possibility of arranging in vertical plane of segment-shaped groove in geometry plane coinciding with working plane of guiding liner of unit for fixing blanks opposite relative to mandrel. EFFECT: improved design. 5 cl, 6 dwg
