103	Forging apparatus	US90184	1979-11-01	US4265105A	1981-05-05	Donald G. MacNitt, Jr.; Bryant H. Walker
The present invention provides methods and apparatus improving the dimensional accuracy of forged components. Uniformity of like component details is sought and a specific object is to provide a die package for forming closely toleranced appendages integrally with a central disk structure from which the appendages extend.In one effective embodiment incorporating concepts of the present invention, the forging dies include a stationary die and a movable die comprising at least two separately movable elements which are mounted on a common axis with the stationary die. A plurality of arcuate die segments are adjacently placed in cylindrical array about the stationary and movable dies. The arcuate die segments form cavities of the inverse geometry of the appendages to be formed and in at least one embodiment are interlocked to prevent tilting of the segments in the die package.The movable die elements are sequenceable to form a billet of material into a workpiece having an intermediate configuration, and subsequently into a workpiece of final configuration. In at least one embodiment, pressure pads are disposed against one of the movable dies to prevent displacement of that die by the billet material as the intermediate configuration is formed.

The present invention provides a technique for improving the dimensional accuracy of forged components. Uniformity of like component details is sought and a specific object is to provide a die package for forming closely toleranced appendages integrally with a central disk structure from which the appendages extend.In one effective embodiment incorporating concepts of the present invention, the forging dies include a stationary die 26 and a moveable die 28 which are mounted on a common axis and a plurality of arcuate die segments 30 which are adjacently placed in cylindrical array about the stationary and moveable dies. The arcuate die segments form cavities of the inverse geometry of the appendages to be formed and are interlocked to prevent tilting of the segments in the die package.

105	Method and apparatus for correcting distortion in gas turbine engine blades	US749847	1976-12-13	US4087996A	1978-05-09	Wilbrod A. Paille
Gas turbine engine blades and single-die cavities are dynamically balanced on a rotor, transferred to a neutral atmosphere heated chamber and rotated. The centrifugal force distributes sufficient stress on both the blade's platform and airfoil to correct critical geometrical characteristics by creep forming in a relatively short time. The process is not affected by the blade surface irregularities, which cause die damage in conventional opposed-die forming due to high stress concentrations.

Means are provided to place an inert atmosphere or vacuum around the dies while they are forging a billet. Chambers are located adjacent the forging means to preheat one billet while another billet is being forged and also to insert and remove a billet without losing much of the heat or forging atmosphere.
107	Process and apparatus for press-forming and quenching a steel stock	US3668917D	1970-01-26	US3668917A	1972-06-13	KOMATSU NOBORU; SUZUKI TAKATOSHI; ITO TAKUO; HARA YOSHITERU; ASAKURA KOUICHI
The invention relates to a process and apparatus for pressforming and quenching a steel stock such as diaphragm spring for automotive clutch use. In the invention, the stock is preparatorily heated to its austenitizing temperature such as about 800* C., or so, placed on one of two cooperating die elements, and then squeezed therebetween under pressure, said die elements having working surfaces having corresponding dimensions and configurations so as to be brought into a pressurized and heat-conducting contact with the to-be-quenched zone of said stock, thereby said stock being press-formed to its desired shape and wholly or locally quenched to a desired hardness such as HRC 60* by conducting substantial amount of heat from the stock to the die elements.
108	Precision forming of titanium alloys and the like by use of induction heating	US3584487D	1969-01-16	US3584487A	1971-06-15	CARLSON ARNE H
Titanium alloy blanks or the like are successively coated with a high-temperature lubricant; preheated, e.g. in a preheat oven or in the forming machine, to a forming temperature (about 1000 1775* F.); precision formed into a desired shape in a press which includes inductively heated forming tools, serving to maintain the metal at the forming temperature throughout the forming operation; and slowly cooled, e.g. first in a postheat oven down to a lower elevated temperature (e.g. about 600* F.) and then down to ambient temperature under cover of an asbestos blanket or the like. The heat-forming tools include a fixed die, a movable die and a movable clamping pad. The movable tools are mounted for precision movement by leader pins and bushings. Insulation and water jackets are interposed between the heated tools and the leader pins and bushings to prevent harmful heating of the latter. The forming tools comprise water-cooled tubular conductors embedded in insulative material which in turn is embedded in die parts of long life metals on which the forming surfaces are machined or embedded in supporting cores therefor.
