The present invention provides a method and apparatus for forming a sheet of ductile 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.

Pressure controlled superplastic forming

A method and apparatus for forming a sheet of ductile material by superplastic forming is disclosed. The method is directed to first creating a pre-form by mechanical forming in which the pre-form is created with a die and punch. Thereafter the pre-form is subjected to gas pressure in a forming cavity to complete formation of the part. A metallic gasket is provided to ensure that no pressurized gas escapes from the forming cavity.

Method and apparatus for gas management in hot blow-forming dies

A superplastic forming tool for forming a workpiece to make a part. The forming tool includes a forming die having first and second die members. At least one of the die members having a cavity including a forming surface and a plenum. A plurality of passageways extend between the plenum and the cavity. The passageways allow passage of fluid between the cavity and the plenum.

Superplastic forming tool

A system and method for superplastic forming a workpiece. The system includes a superplastic forming cell formed of a plurality of individual stations or modules, each one performing a specific manufacturing step or process on the workpiece. Individual stations include a preheat station, a forming station, a cooling station, a cleaning station and a trimming station. These stations work in conjunction with one another to reduce superplastic forming cycle times and correspondingly increased production times when manufacturing a workpiece using a superplastic forming process.

System and process for superplastic forming

An apparatus and method for heating and transferring a workpiece to a forming press for superplastic forming. The apparatus includes a heater assembly, having upper and lower heated platens, mounted to a frame. The heater assembly heats the workpiece to a predetermined temperature. A shuttle assembly operates to remove the heated workpiece from the heater assembly and transfer it to the forming press for forming.

Apparatus and method for heating and transferring a workpiece prior to forming

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.

Apparatus and method for removing and cooling a part from a forming tool

A super-plastic forming tool for forming aluminum sheets is provided that includes a seal bead that is configured to facilitate removal of the aluminum sheet from the seal bead after a super-plastic forming operation. Contraction of the aluminum sheet at a faster rate than the super-plastic forming tool facilitates removal of the aluminum sheet due to the specific geometry of the seal bead. The seal bead has a more shallowly sloped outer surface than its inner surface and may be provided in different configurations including flat, convex, concave shapes.
