Process for hot forming hollow spherical bodies |
摘要 |
A process for forming a hollow spherical body and the spherical structure so formed. The forming includes a first phase in which a blank is provided with a half having a spherical outer surface, a remaining part having two concentric, outer and inner walls with an axial hole that is closed by an intermediate plate. In a subsequent phase the outer wall of the remaining part of the blank is given a spherical shape in continuation of the spherical half obtained in the first phase of forming.
