    摘要: A press and tooling apparatus for forming a preheated blank includes a heated upper tool and an opposing heated lower tool mounted within the press for relative closing movement to press the preheated blank there between. A binder ring assembly surrounds the lower tool and is mounted on the press for movement relative to the lower tool so at to bind the preheated blank to the upper tool in air tight sealing relationship in readiness for closure of the tools and application of pressurized gas to force the blank into contact with the upper tools. The binder ring assembly includes an upper ring that is heated so as to prevent the cooling of the preheated blank, and a lower ring that supports the upper ring and is fixedly connected to the upper ring by spaced apart connectors so as to minimize the heat transfer path from the heated upper ring to the lower ring. The upper and lower rings have opposed seal surfaces spaced from one another to receive there between a seal of metallic hollow tubular construction which provides fluid tight sealing between the upper and lower rings, and minimizes heat transfer there between.

    摘要: A forming apparatus and method for minimizing wrinkling in the forming of a three-dimensional component from a two-dimensional blank. The forming apparatus includes vertically opposed sets of tools or binders. A first tool or binder apparatus has first and second sets of opposed sides having contoured binder surfaces. A second tool or binder apparatus is mounted in vertically opposed relation to the first binder apparatus, and includes first and second sets of opposed tool or binder segments that have contoured binder surfaces thereon that are complementary in shape to the respective binder surfaces of the first and second sets of opposed sides of the first binder apparatus. One of the first and second sets of opposed binder segments of the second binder apparatus have substantially similar contours and the other have different contours. One of the first and second sets of opposed binder segments of the second binder apparatus is elevated and movable with respect to the other.

    摘要: A method is disclosed for forming sheet metal articles, such as automotive body panels, having significant curvatures in front-to-back and side-to-side directions. Opposing, complementary, preforming and final shape forming tools are used in a single press. A sheet of superplastically or quick plastically formable sheet metal alloy, heated to a forming temperature, is first stretched against the preform tool using pressurized gas to form a preform that has experienced most of the metal stretching required for the final part shape. The preform is removed from the preform tool and formed against the opposing tool with pressurized gas to obtain the final sheet metal part shape.
