CURVED SUPERPLASTIC FORMING/DIFFUSION BONDING SANDWICH FABRICATED STRUCTURES |
摘要 |
The process for forming a metallic sandwich structure having a curved surface, particularly a surface curving about more than one axis, such as a quadric surface partially by direct displacement and partially by a fluid interface. Additionally, means to restrain the work sheets being formed with respect to the shaping fixture which allow a portion of the work sheets to flow into the forming cavity before absolute restraint is applied and the restraining means function independently of the clamping force of the press. |
