1. A forging press for flow forging a metal workpiece into a shaped part under the application of continuous pressure comprising: a support frame having a central opening forming an upper frame section, a lower frame section and side sections, an upper platen adapted to be suspended vertically from the upper frame section of the support frame, a lower platen extending from the lower frame section at a location spaced apart from the upper platen, with the upper platen comprising a shoulder extending from each opposite side thereof aligned substantially in a horizontal direction in relative close proximity to each side section of the support frame respectively, a wedge assembly including a first and second wedge member mounted in sliding engagement upon each shoulder of the upper platen at a position disposed between the upper platen and the upper frame section, with the first and second wedge members each having an inclined surface on at least one side thereof adapted to engage the upper frame section, an end support member interconnecting the first and second wedge members at a location external of the support frame; a first endless roller chain assembly surrounding the upper platen in a continuous loop; a second endless roller chain assembly surrounding the lower platen in a continuous loop with the first endless roller chain assembly facing the second endless roller chain assembly in substantial parallel alignment; and a motorized worm gear assembly for controllably moving said wedge assembly in or out of the central opening of the support frame so that the upper platen moves in a direction relative to the lower platen to control the pressure applied to the workpiece as the workpiece is transported via a die assembly between the upper and lower platens. 2. A forging press as defined in claim 1 wherein said support frame is composed of a plurality of metal plates integrated as a single unit to form a unitary structure of any desired thickness. 3. A forging press as defined in claim 2 wherein said lower platen is formed from or affixed to said lower frame section and includes a flat plate disposed on a surface thereof spaced apart from the upper platen upon which is mounted the second endless roller chain assembly. 4. A forging press as defined in claim 3 wherein said motorized worm gear assembly comprises a lead screw, a gear assembly and a motor with the lead screw extending from the gear assembly through the upper frame section of the support frame. 5. A forging press as defined in claim 4 wherein said gear assembly and motor is mounted on said end support member external of the support frame. 6. A forging press as defined in claim 4 wherein said motor is a stepping motor. 7. A system for flow forging a metal workpiece into a shaped part under the application of continuous pressure comprising in combination; a heating station for preheating the metal workpiece, a die assembly, including a male die composed of a plurality of male die segments and a female die, a forging press and a trailing assembly, with the trailing assembly including an hydraulically operated piston drive assembly for transporting the die assembly and heated workpiece from the heating station through the forging press, wherein the forging press comprises: a support frame having an upper frame section, a lower frame section and side sections, an upper platen adapted to be suspended from the upper frame section of the support frame with the upper platen comprising a shoulder extending from each opposite side thereof aligned substantially in a horizontal direction in relative close proximity to each side section of the support frame and a tapered inclined surface on each end thereof, a lower platen extending from the lower frame section at a location spaced apart and in parallel alignment to the upper platen, a wedge assembly mounted upon the upper platen in sliding engagement between the upper platen and the upper frame section, an endless roller chain assembly surrounding the upper platen, another endless roller chain assembly surrounding the lower platen with each endless roller chain assembly forming a continuous loop about the upper and lower platen respectively; and a motorized worm gear assembly for controllably moving said wedge assembly so that the upper platen moves in a direction relative to the lower platen for controlling the pressure applied to the workpiece as the workpiece is moved with the die assembly in a transport direction between the upper and lower platen such that each of said plurality male die segments is pressed gradually and sequentially against the workpiece into the female die as the die assembly moves through the press. 8. A system for flow forging as defined in claim 7 wherein each endless roller chain assembly is spaced apart from one another to enable the workpiece to be moved in a transport direction between both endless roller chain assemblies. 9. A system for flow forging as defined in claim 8 wherein said motorized worm gear assembly in said forging press comprises a lead screw, a gear assembly and a motor with the lead screw extending from the gear assembly through the upper frame section of the support frame for controlling the pressure applied to the workpiece as the workpiece moves between both endless roller chain assemblies. 10. A system for flow forging as defined in claim 9 wherein the length of the workpiece controls the number of male die segments in the die assembly such that any length of workpiece can be forged. 11. A system for flow forging as defined in claim 10 wherein the heating station for preheating the metal workpiece comprises a furnace of modular construction consisting of a plurality of heating units having a length to accommodate any length of workpiece based upon the number of male die segments. 12. A system for flow forging as defined in claim 11 wherein the trailing assembly further comprises two indexing plates defining a channel through which the die assembly following the forging operation is withdrawn with the indexing plates having index holes spaced a given distance apart along the longitudinal length of the plates for defining the distance the die assembly is to be withdrawn from the press so as to enable the hydraulically operated piston drive assembly to withdraw a workpiece of any desired length.
