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： 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 self-contained die cushion assembly for use in a stretch-forming process involving heated tooling. A lower plate is mounted below an upper plate that undergoes different thermal expansion than the lower plate. Guidance devices are mounted between the upper and lower plates and include a guide post, a bearing sleeve circumscribing the guide post, and a cylinder circumscribing the bearing sleeve. The guide post is mounted in fixed relation to the upper plate, and the cylinder is mounted in laterally translatable relation to the lower plate to accommodate lateral relative displacement between the upper and lower plates due to different thermal expansion thereof, thereby preventing binding of the guidance devices.

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.

摘要： An apparatus for forming blanks having two thicknesses separated by a blank step includes a forming tool defining a binder surface that is characterized by a tool step, a first region on a first side of the tool step, a second region on a second side of the tool step, and a bead segment having a surface contiguous with the second region. The bead segment is configured to pinch material from a blank into any gap created between the tool step and the blank step caused by misalignment of the blank in the tool, thereby ensuring an effective seal to form the blank against a forming surface.

摘要： A hot blow-forming apparatus includes opposed and complementary forming tools adapted for hot blow forming a surface of a heated sheet-metal workpiece against a forming surface of one of the tools. The tools are also adapted to close upon and grip a peripheral edge of the workpiece and perform work on a central portion of the workpiece to produce a formed panel. The tools incorporate an improved extraction apparatus, which includes a plurality of opposed and complementary spring-loaded extractor pads. Opposed extractor pads are spring-loaded to different levels so as to apply spring-load differentials therebetween and thereby apply different extraction forces in different locations of the resultant formed panel for distortion-free removal of the formed panel from the working surfaces of the tooling.

摘要： Apparatus and method for hot blow-forming an article from a blank of sheet metal. Simultaneously, a surface of the blank of sheet metal is formed against a form tool body that partially defines a forming surface and against a form tool insert that also partially defines the forming surface and that is positioned within a recess of the form tool body such that a lateral gap is defined between the form tool insert and form tool body. Opposed projections are provided on upper surfaces of the form tool insert and the form tool body adjacent the gap. The projections create a raised portion on the sheet metal panel that corresponds to the gap. The raised portion is removed flush with respect to a visible surface of the article.
