Abstract: A sheet metal forming process and apparatus using both a mechanical forming step and a superplastic forming step. The mechanical forming step includes using a double-action draw die to create a preform. The preform is then transferred to a superplastic forming tool that uses a superplastic forming process to complete the forming process and create a finished workpiece. Using the mechanical forming step enables rapid creation of a preform having a geometry that reduces overall forming time and provides the ability to draw in additional material to reduce part thinning.

Abstract: An apparatus and method for removing a part from a forming tool and supporting the part. The apparatus includes a support member having a surface contoured to conform to a formed shape of the part and an aperture disposed in the surface. A manipulator moves the support member near the part while the part contacts the forming tool. Pressurized gas is directed toward the part to cause the release of the part from the forming tool and to cool the part. The surface supports the part to inhibit distortion as the part cools.

Abstract: The present invention provides a method and apparatus for forming a ductile sheet or work piece into a part or component. The method includes using a forming apparatus wherein the workpiece is placed between and upper die and a blank holder and then lowered onto a punch such that continued lowering of the upper die draws the workpiece around the punch. Once the draw process is complete, gas pressure acts on one side of the workpiece to press the workpiece against a forming surface of the punch to complete the forming process.

Abstract: A creep testing fixture and method for applying a precise amount of constant tensile stress to a creep test specimen to allow for precise measurement of creep in the test specimen. The fixture includes first and second mounting grips for holding opposite ends of a test specimen. A frame supports the mounting grips for relative reciprocal movement toward and away from each other. A tensile spring is connected between the first and second mounting grips. The frame subjects a test specimen held between the mounting grips to tensile stress in response to axially inward force that the tensile spring applies to the frame.

Abstract: The present invention provides a method and apparatus for forming a sheet of ductal material by superplastic forming. The gas pressure is varied to control the material flow during the forming process. Accordingly, the gas pressure can be increased or decreased to control the rate of deformation of the workpiece. Accordingly, the method and apparatus contemplates the use of predetermined pressure profiles to reduce the overall forming time.
