FIELD: metallurgy; technological processes.SUBSTANCE: invention relates to cold metal forming, particularly, to methods and devices for straightening. Radial load applied to a blank, ends part are fixed jointed, radial load is created by two rollers by transverse deformation of the shaft for a certain design equation value. Wherein rollers are arranged symmetrically about the center part, a part is revolved about its axis to balance the stresses at its section.EFFECT: higher quality of parts due to elimination of residual stresses is provided.1 cl, 1 dwg |
