摘要： A die liner for use in a die having a die body wherein the die body is configured to form a workpiece. The die liner is a discrete structure that is configured to be used in conjunction with the die body. The die liner defines a forming surface for forming the workpiece and is configured to have at least one characteristic that is different than a corresponding characteristic of the die body such that the die liner increases the durability of the die.

摘要： Apparatus and methods for single sheet forming using induction heating include a pair of dies defining a die cavity for containing a workpiece, which is inductively heated by an oscillating magnetic field within the die cavity. A susceptor is positioned between the workpiece and one die surface defined by one of the dies. The susceptor is capable of coupling with the oscillating magnetic field to induce a current within the susceptor to heat the susceptor. The susceptor transfers heat to the workpiece. An inlet for pressurized forming fluid injects the fluid between the susceptor and the workpiece to form the workpiece into direct contact with a forming surface defined by one of the dies. The susceptor may be electrically connected to the workpiece to inhibit electrical arcing from the susceptor to adjacent electrically conductive components when current is induced in the susceptor. The apparatus may further include a seal frame that releasably engages the workpiece to form a pressurizing cavity between the susceptor and the workpiece. The inlet injects the fluid into the pressurizing cavity to develop and apply forming pressure to the workpiece.

摘要： An induction heating device for manufacturing a part by heating the part to a predetermined temperature. The induction heating device includes an induction coil connected to an electrical power supply for generating an electromagnetic flux field. A smart susceptor of the heating device is positioned in the electromagnetic flux field and includes a magnetically permeable material supported by a mesh structure. The magnetically permeable material generates heat in response to the flux field. The mesh structure provides support for the magnetically permeable material and closely conforms to the desired outer geometry of the part. The magnetically permeable material may be applied as a powder to the mesh using a hot spray gun, allowing tight conformance of the susceptor to the part geometry while avoiding forming limits of sheet metal susceptors.

摘要： An apparatus and method for heat treating a structural member, for example, to relieve stresses therein, are provided. The structural member is restrained in a die cavity by one or more inflatable bladders so that a desired dimensional accuracy is achieved. The structural member can be heated by an electromagnetic field generator, such as an induction coil, that heats one or more susceptors to a characteristic Curie temperature. The apparatus can be used to process structural members of various sizes and shapes, and the heating and cooling cycle can be performed relatively quickly.

摘要： A superplastically formed, diffusion bonded sandwich structure having integral metal hardpoints, made by joining two superplastic metal core sheets together into a core pack by welding or diffusion bonding along a pattern of lines which form junction lines between the core sheets when the pack is inflated by gas pressure at superplastic temperatures. Face sheets are laid under and over the core pack and metal inserts are interposed between the face sheets and the core. All of the sheets in the pack are sealed together around an outside peripheral edge to create a gas tight envelope. The pack is heated to superplastic temperatures in a cavity in a die, and the top and bottom face sheets are diffusion bonded to top and bottom surfaces of the metal insert by application of heat and pressure from top and bottom inner surfaces of the die cavity. While at superplastic temperatures, the pack is inflated by gas pressure against inside surfaces of a die to form an expanded metal sandwich structure having integral webs and integral hardpoints formed by the metal insert. After forming, the gas pressure is reduced to near atmospheric, the die is opened and the part is removed from the die.

摘要： A gas management system for delivering forming gas under a controlled pressure through a first portion of a piping network to a region of a forming die between a die lid and a blank to be formed in a superplastic forming machine includes a gas pressure regulator in the piping network and two control loops. The first control loop has a first pressure transducer communicating with the piping network downstream of the gas pressure regulator and operatively with the gas pressure regulator. The second control loop includes a pulse controller downstream of the first pressure transducer and a second pressure transducer communicating with the piping network downstream of the pulse controller and operatively with the pulse controller. The gas pressure regulator receives signals from a controller to adjust the pressure at which the gas pressure regulator opens to release gas through the pressure regulator. The system delivers inert gas to a superplastic forming die at a predetermined pressure on a predetermined schedule to achieve optimum forming speed and quality.
