где B - ширина кольцевой зоны разупрочнения трубы; S0 - толщина трубы; D - наружный диаметр трубы; h - расстояние от нейтральной оси гибки разупрочняемого участка трубы, εдоп - допустимая степень осадки материала трубы при заданной температуре ее нагрева.The invention relates to the processing of metals by pressure, in particular to the technology of bending pipes for use in shipbuilding, mechanical engineering, aerospace and other industries. The technical result achieved with the use of the invention is to ensure the bending of pipes with zero radii of bending. In the developed method, metal pipes are flexible, including local softening of the pipe billet with an annular heater, mainly induction, and application of a bending moment with an upsetting force to the weakened pipe section; and the upsetting force in the bending zone is created by the approach of the end sections of the pipe billet to the required bending angle of the latter. The width of the annular zone of softening of the workpiece is performed according to the following dependence: b = 6 • S 0 • h / D, and the bending angle of the pipe blank is set to no more
where B is the width of the annular zone of pipe softening; S 0 - pipe thickness; D is the outer diameter of the pipe; h is the distance from the neutral axis of the flexible section of the pipe are flexible, ε additional - the permissible degree of settlement of the pipe material at a given temperature of its heating.
