Abstract

1. Способ изготовления оболочек, включающий изготовление выдавливанием из отрезка прутка полой фасонной заготовки, последующую обработку резанием внутренней и наружной поверхностей, ротационную вытяжку с утонением с допустимой степенью деформации, термическую обработку и окончательную обработку резанием, отличающийся тем, что оболочку изготавливают моноблочной с дном, на котором с внешней и/или внутренней стороны размещены местные утолщения.2. Способ по п.1, отличающийся тем, что местные утолщения превышают минимальную толщину оболочки не менее чем в 10 раз.1. A method of manufacturing shells, including the production of extruding a hollow shaped billet from a section of a bar, subsequent processing by cutting the inner and outer surfaces, a rotational hood with thinning with an acceptable degree of deformation, heat treatment and final cutting, characterized in that the shell is made monoblock with a bottom, on which local thickenings are located on the external and / or internal side. 2. The method according to claim 1, characterized in that the local thickenings exceed the minimum shell thickness by at least 10 times.
