摘要： An elevated temperature forming system in which a sheet metal workpiece is provided in a first stage position of a multi-stage pre-heater, is heated to a first stage temperature lower than a desired pre-heat temperature, is moved to a final stage position where it is heated to a desired final stage temperature, is transferred to a forming press, and is formed by the forming press. The preheater includes upper and lower platens that transfer heat into workpieces disposed between the platens. A shim spaces the upper platen from the lower platen by a distance greater than a thickness of the workpieces to be heated by the platens and less than a distance at which the upper platen would require an undesirably high input of energy to effectively heat the workpiece without being pressed into contact with the workpiece.

摘要： A tooling assembly for hot stretch-forming of a sheet metal workpiece. A forming tool is attached to a plate and includes a shell having a forming surface, and support walls that extend away from the shell, that terminate in a rearward surface of the forming tool, and that define open cells between the support walls. Heating elements are embedded within the forming tool for integral and uniform heating thereof. To limit conductive thermal losses from the forming surface, through the forming tool, and to the plate and surrounding environment, the open cells are provided in the forming tool and insulative support posts are disposed between the forming tool and the plate within deep counterbores in the rearward surface of the forming tool. To limit radiative and convective thermal losses, thermal insulation is disposed within the cells and between the forming tool and plate.

摘要： A flask and tool assembly includes a forming tool insert that is housed within an insulated flask having four vertical sides. An insulation enclosure surrounds the flask and the flask contains a heater plate for contacting the bottom of the forming tool insert. The tops of the sides of the flask provide surfaces for gripping bottom edges of a sheet metal blank to be formed. A cover for the tool-containing flask provides complementary gripping surfaces for top edges of the sheet metal blank and defines a chamber above the sheet metal blank for pressurized forming gas. A peripheral seal underlies the sheet metal blank and bridges a space between the outer side surfaces of the forming tool insert and the inner surfaces of the sides of the flask, thereby obviating the need to provide a precision fit between the flask and forming tool insert.

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 heating a cold worked sheet of superplastically formable metal composition to recrystallize its microstructure to a formable condition and/or to heat the sheet to a temperature for an immediate forming operation. The sheet is placed between two electrical resistance heated platens maintained at a suitable temperature for recrystallizing and/or heating the metal sheet through its side surfaces. In a preferred embodiment a critical gap is maintained between the platens and the sheet to permit rapid conductive heating of the expanding sheet without marring its surfaces.

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.
