Abstract: A reciprocating rotary tool driver is driven by a motive source which provides power to its tool through a splined shaft while the rotating tool is oscillated in a vertical mode by means of spur gear, worm gear, and crank means.

Abstract: A platen for a press is disclosed providing fast heatup rate for materials to be superplastically formed, diffusion bonded, etc. The platen includes a ceramic plate having channels in its upper surface. A copper tube positioned within the channels conducts both electricity and cooling fluid therethrough. A metallic top plate positioned on top of the ceramic plate is induction heated by the electromagnetic field produced by the electrical current flowing through the copper tubing. A steel trough member covers the sides and bottom lengthwise portions of the copper tube in order to focus the electromagnetic waves upward into the top plate. The cover is composed of segments which are electrically insulated from each other in order to enhance the focusing effect. The ceramic plate is a heat and electrical insulator, and the upper surface thereof reflects radiant heat toward the top plate. A steel base plate provides firm support for the ceramic plate, the top plate and the other component elements.

Abstract: Apparatus and related process steps are disclosed for manufacturing titanium alloy sheet metal parts over a die form using radiant heating, particular mechanical motions, and differential fluid pressures in specific sequences of operations. The resulting parts have configurations with substantial depths and are produced both at accelerated rates and with reduced alloy contamination in comparison to known titanium sheet metal forming practices.
