Claims (2)

1. Способ изготовления полых деталей со ступенями на наружной поверхности, включающий осадку-калибровку отрезанной заготовки с выравниванием торцов и образованием конических наметок на двух ее сторонах, дальнейшую осадку с образованием головки, выдавливание отверстия в заготовке, уменьшение наружного диаметра с образованием ступеньки, прошивку отверстия в заготовке, отличающийся тем, что при уменьшении наружного диаметра с образованием ступеньки заготовка, перемещаясь, упирается торцом в съемник, пуансон продолжает движение и входит в отверстие заготовки, дальнейшее перемещение заготовки совершается совместно с пуансоном и съемником.1. A method of manufacturing hollow parts with steps on the outer surface, including draft-calibration of the cut workpiece with the alignment of the ends and the formation of tapered basting on its two sides, further draft with the formation of the head, extruding a hole in the workpiece, reducing the outer diameter to form a step, piercing the hole in the workpiece, characterized in that when the outer diameter is reduced to form a step, the workpiece, moving, abuts the end face of the puller, the punch continues to move and enters into the hole of the workpiece, further movement of the workpiece is carried out together with the punch and puller. 2. Холодновысадочный инструмент для изготовления полых деталей со ступенями на наружной поверхности, выполненный в виде многопозиционного блока, содержащий пуансоны и сборные матрицы, установленные в корпусах на подкладках, оснащенные толкателями и выталкивателями, при этом сборные матрицы состоят из вставок и подкладок, с перемещающимися внутри съемников пуансонами, отличающийся тем, что на четвертой позиции сборная матрица выполнена неподвижной с редуцирующей ступенькой на вставке, пуансон установлен подпружиненным, в выдвинутом положении относительно редуцирующей ступеньки.2. Cold heading tool for the manufacture of hollow parts with steps on the outer surface, made in the form of a multi-position block, containing punches and prefabricated dies installed in cases on the lining, equipped with pushers and ejectors, while the prefabricated dies consist of inserts and pads with moving inside pullers with punches, characterized in that in the fourth position the prefabricated matrix is made stationary with a reducing step on the insert, the punch is installed spring-loaded, in the extended p positions with respect to the reducing step.
