Latest Patents

Robert A Testin holds a patent for a "Method and apparatus for expansion forming a workpiece using an external deformable supporting fixture." This invention relates to an external cylindrical or conic section shaped fixture that fits tightly around a workpiece prior to the expansion forming process. The design allows for one-time use and is particularly beneficial for workpieces with brazed lap joints. The external fixture restrains out-of-plane joint rotation and reduces stress concentrations near the lap joints. It also provides additional load-carrying capability, improving load distribution during the forming process. Notably, no modifications are required for the existing expansion forming machinery or inner expander dies.
