Способ изготовления гнутых профилей проката относится к обработке металлов давлением и предназначен для изготовления гнутых профилей проката (ГПП) в черной металлургии, транспортном и сельскохозяйственном машиностроении и судостроении. Цель изобретения - повышение качества ГПП путем уменьшения радиусов (Р) мест изгиба (МИ) готового профиля. При многопереходной подгибке плоских элементов профиля с одновременным радиальным и тангенциальным сжатием МИ по крайней мере одно МИ одновременно с радиальным и тангенциальным обжатием формуют постоянным по переходам P, равным минимально допустимому из условия отсутствия трещинообразования, и последовательно по переходам смещают либо внутренний край формуемого участка МИ в направлении от края полосы к ее середине, либо внешний край формуемого участка МИ в направлении от середины полосы к ее краю.A method of manufacturing curved rolled sections refers to the processing of metals by pressure and is intended for the manufacture of curved rolled sections in the ferrous metallurgy, transport and agricultural engineering and shipbuilding. The purpose of the invention is to improve the quality of the GPP by reducing the radii (P) of bending points (MI) of the finished profile. With multi-junction bending of flat profile elements with simultaneous radial and tangential compression of MI, at least one MI simultaneously with radial and tangential compression is formed by constant at transitions P equal to the minimum allowable of the absence of cracking, and successively at transitions shift direction from the edge of the strip to its middle, or the outer edge of the molded portion of the MI in the direction from the middle of the strip to its edge.
