    摘要: A quick plastic forming (QPF) tool is provided in which a thermal gap is created that reduces or eliminates some of the conductive heat loss paths when the QPF tool is in an open position during part removal or sheet loading. By reducing conductive heat loss, a more precise temperature control for the QPF tool from manufacturing cycle to manufacturing cycle may be realized. The QPF tool may also have a thermal gap when the tool is placed in a semi-open position during idle times. The QPF tool may also include components for creating the thermal gap when the QPF tool is moved to the open position and control the lateral movement of the part forming section of the QPF tool as the part is moved between the open position and the closed position.

    摘要: Method of preforming and forming a sheet metal article from a preheated blank of sheet metal uses opposing dies including a punch having a punch surface defining a final configuration for the article and a cavity die having a cavity surface defining a preform configuration. The blank is placed between the dies and has a first side surface facing the cavity die and a second side surface facing the punch. A vacuum is applied to the first side of the blank to draw and shape the blank into the cavity die to a preform configuration conforming to the cavity surface. The punch and the cavity die are then closed toward one another and gas pressure is then applied to the first side surface of the blank to press the second side surface against the punch surface to the finish configuration.

    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: Work hardenable aluminum alloy sheet material is progressively stamped to a final stamped shape in a succession of stamping operations. A blank sheet of annealed starting material is stamped into a least a first preform shape between heated stamping tools to form a preform shape and subsequently anneal the worked preform shape. After one or more annealed preform shapes have been progressively attained, the last preform shape is cooled, if necessary, and stamped to its final stamped shape between unheated stamping tools.

    摘要: An improved forming tool apparatus for forming an article having a negative draft angle that locks the formed article within the forming tool. First and second forming tools are closed relative one another to define a forming tool cavity in which the article is formed and opened for removal of the formed article from the forming tool cavity. The first forming tool has a removable cavity wall segment having an undercut cavity wall that provides a desired shape to the formed article but locks the formed article against removal from the forming tool cavity. A pivot linkage normally establishes the removable wall segment in a forming position in which the undercut wall is poised for forming of the article and selectively pivots the removable wall segment out of the forming position when the forming tools are opened so that the undercut wall is pivotally lifted and releases the formed article for removal from the cavity.

    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 by the final shape tool 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, final shape tool with pressurized gas to obtain the final sheet metal part shape.

    摘要: A method for forming sheet metal articles, such as automotive body panels, having complex curvatures. Opposing, complementary, pre-form and finish-form tools are used in a single press. A sheet of hot blow-formable sheet metal alloy, heated to a forming temperature, is placed between the tools. The pre-forming tool is lowered to a first stage closed position thereby trapping edges of the sheet between binder surfaces of the tools. The sheet is first stretched against the pre-form tool using pressurized gas to form a pre-form that undergoes most of the metal stretching required for the final part shape. Then the finish-form tool is pivotably advanced into a second stage closed position. The pre-form is displaced away from the pre-form tool and hot plastically formed against the opposing finish-form tool with pressurized gas to obtain the final sheet metal part shape. The finish-form tool is then pivotably retracted so as to avoid die lock or part interference conditions.
