Substantiation of the need to create the technology of stretch forming shells double curvature shell using new alloys

[摘要] The technology of stretch forming shells doubly curved shell should take into account the kinematic features of the stretching press and the plastometric characteristics of the sheet blanks when performing a sequential scheme of stretch forming. The technology is characterized by some parameters. They include the following groups: material properties; friction conditions; dimensions of the sheet blank; heat treatment conditions of the sheet material; the placement parameters of the stretch die on the bed of press; technological conditions of the process of obtaining shell details of the minimum thickness variation on stretching press with program control.
