1. Способ ротационной вытяжки полых осесимметричных деталей, включающий ротационную вытяжку исходной заготовки на вращающейся оправке несколькими коническими роликами, расположенными в одной плоскости, перпендикулярной оси вращения оправки, отличающийся тем, что деформирование исходной заготовки осуществляют в непрерывном очаге деформации с разделением его на несколько зон, последовательно расположенных вдоль оси вращения оправки и наклоненных к ней под различными углами с возрастанием угла наклона от начала к концу очага деформации, при этом ротационную вытяжку осуществляют при равных радиальных нагрузках на каждый ролик, что достигают путем взаимного смещения роликов друг относительно друга в радиальном направлении в зависимости от величины суммарной деформации на обрабатываемом участке и геометрических параметров каждого ролика.1. The method of rotational drawing of hollow axisymmetric parts, including rotational drawing of the original workpiece on a rotating mandrel with several tapered rollers located in one plane perpendicular to the axis of rotation of the mandrel, characterized in that the initial workpiece is deformed in a continuous deformation zone with its division into several zones, sequentially located along the axis of rotation of the mandrel and inclined to it at different angles with increasing angle of inclination from the beginning to the end of the deformation zone and wherein the rotary hood is carried out at equal radial loading on each roller, which is achieved by mutual displacement of the rollers relative to each other in the radial direction depending on the magnitude of the total strain on the treated area and geometric parameters of each roller. 2. Способ по п. 1, отличающийся тем, что отдельные зоны очага деформации формируют несколькими роликами с одинаковыми геометрическими параметрами. 2. The method according to p. 1, characterized in that the individual zones of the deformation zone are formed by several rollers with the same geometric parameters.
