Способ формовки трубной заготовки относится к производству труб и может быть использован при формовке трубной заготовки. Изобретение позволяет повысить качество формовки за счет снижения неравномерности деформации трубной заготовки. Способ включает последовательную по переходам, например в клетях формовочного стана, подгибку элементов заготовки. Вначале подгибают периферийные участки заготовки радиусом, равным 0,9 oC 1,1 радиуса трубы, и углом гиба 45 - 65°. Затем эти и другие участки подгибают по кривым четвертого порядка типа овала Кассини с монотонно убывающим межфокальным расстоянием.The method of forming a billet relates to the production of pipes and can be used when forming a tube billet. The invention allows to improve the quality of the molding by reducing the non-uniformity of deformation of the billet. The method includes sequential transitions, for example in the stands of the forming mill, bending of the workpiece elements. First, bend the peripheral areas of the workpiece with a radius of 0.9 o C 1.1 of the radius of the pipe, and a bending angle of 45 - 65 °. Then these and other areas are folded along fourth-order curves of the Cassini type with a monotonously decreasing interfocal distance.
