FIELD: plastic metal working, namely manufacture of high-accuracy parts formed of sheet blanks. SUBSTANCE: method comprises steps of clamping blank edges to movable members of die and their common motion - at first along axis of die set until formation of necessary inclination angles of part walls and then - in opposite direction until providing necessary height of part cross section at keeping formed angles. EFFECT: enhanced accuracy of bent parts, lowered forming efforts. 1 dwg, 1 ex
