Способ изготовления изделий переменного по их длине сечения, включающий закрепление заготовки с обоих ее концов, к одному из которых прикладывают осевое усилие натяжения, а со стороны другого вдавливают неприводные валки с калибром полного охвата заготовки и прикладывают осевое усилие протягивания, прокатывание заготовки до получения сдвоенной ступенчатой заготовки, площадь поперечного сечения которой уменьшается от концов середине, путем ее возвратно-поступательного перемещения и радиального перемещения валков, определяемого программой обработки для каждого рабочего хода, с поворотом заготовки после каждого рабочего хода вокруг продольной оси, со сменой калибра валков, при формировании каждой ступени заготовки и изменением величины ее хода в соответствии с удлинением обрабатываемого участка заготовки, отличающийся тем, что в качестве исходной заготовки обработке прокатыванием подвергают тонкостенную трубчатую заготовку, смену валков с изменением их калибра производят перед окончательным проходом на каждой ступени, а величину прилагаемого усилия натяжения изменяют на каждом проходе, причем это изменение осуществляют в зависимости от площади поперечного сечения заготовки на данном проходе.A method of manufacturing products of variable cross-sectional length, including securing the workpiece from both its ends, applying axial tension to one of them and pressing non-drive rolls with the caliber of full coverage of the workpiece from the other and applying axial pulling force, rolling the workpiece to obtain a double step blanks, the cross-sectional area of which decreases from the ends of the middle, by its reciprocating movement and radial movement of the rolls, determined by prog the processing frame for each working stroke, with the rotation of the workpiece after each working stroke around the longitudinal axis, with the change of the caliber of the rolls, during the formation of each step of the workpiece and the change in the value of its stroke in accordance with the lengthening of the processed section of the workpiece, characterized in that as the initial workpiece is processed thin-walled tubular billet is subjected to rolling, rolls are changed with their caliber changed before the final pass at each stage, and the magnitude of the applied tension force and change on each pass, and this change is performed depending on the cross sectional area of the workpiece at this passage.
