发明名称 Method and apparatus for forming thin parts of large length and width
摘要 Method and apparatus for fabrication of large thin parts, such as panels having integral stiffeners arranged in any desired pattern, for superplastic and semisolid forming of complicated components, and for consolidation and bonding of powder and composite materials into flat products, include forging-rolling between a flat die and a circular die with a ratio of a contact length between the circular die and a billet to a billet thickness between 20-75 that prevents a material flow in a rolling direction and extrudes the material into die cavities. The circular die is formed as a ring-shaped element sliding along cylindrical guide surface. Both dies are displaced by press to squeeze and forge a billet into a product. For semicontinuous processing of very long parts, the dies are divided into a plurality of sectioned elements which are periodically introduced into a working zone.
