Формула изобретенияClaim Способ изготовления полых цилиндрических заготовок, включающий операции нагрева и прошивки заготовки прошиванием, отличаюши йся тем, что, с целью повышения производитель15 ности, исключения потери металла в выдру и уменьшения усилия прошивки, одновременно с прошивкой производят ковку заготовки по боковой поверхности с ее вращением, со степенью деформации 10-30% 20 и с углом поворота заготовки после каждого обжатия на 10-30°, при этом прошивню придают вращение в сторону, обратную вращений, заготовки с угловой скоростью, равной 3-5 угловым скоростям (5 вращения заготовки.A method of manufacturing hollow cylindrical billets, including heating and flashing the workpiece by flashing, characterized in that, in order to increase productivity, eliminate metal loss in the otter and reduce the flashing effort, forging the workpiece is forged along the side surface with its rotation, with the degree of deformation is 10-30% 20 and with the angle of rotation of the workpiece after each compression by 10-30 °, while the firmware is rotated in the direction opposite to the rotation of the workpiece with an angular velocity equal to 3-5 angular speeds pits (5 rotation of the workpiece.
