FIELD: plastic metal working.
SUBSTANCE: invention can be used for bending and straightening of rolled sections and strips. According to proposed method of bending, blank is moved longitudinally, and bending forces and counteracting forces spaced relative to bending forces are applied square to flange of blank determining outer radius of bending and parallel to its free walls. Hindering forces are applied in place of action of bending force square to free walls of blank to decrease buckling. Device provided with pressure and support deforming members made in form of rollers whose shape corresponds to cross section of parts under bending has slots in pressure roller with widening from roll axis for free walls of blank.
EFFECT: improved quality of product owing to reduced buckling of free walls of section and specific consumption of material and power.
