4813263 FORGING
MACHINE
Hans Schubert, Klaus Schulze, Dusseldorf~ Federal Republic Of Germany assigned to SMS Hasenclever Maschinenfabrik GmbH A forging machine having rams arranged in the form of a cross carry respective tools adjustable transversely to the ram axes and partly overlapping one another, so that a closed pass can be formed for any size of the forging pass. To adjust the tools transversely, each tool is carried on a respective crosspiece which can be clamped against the ram end or can be released and moved transversely on the ram. The clamping and releasing and the adjustment movement are all effected by a rotary tie rod extending through the crosspiece and through the ram, having one end coupled to the crosspiece for clamping it and moving it transversely to the ram, and the other end coupled to a clamping mechanism and to a rotary adjustment drive.
481~31 COUPLING SYSTEM FOR CUTTING SHANK TOOLS Josef Reinauer, Sigmaringen, Federal Republic Of Germany assigned to Gottlieb Guhring KG Described is a coupling system for cutting shank tools with which a stationary connection can be produced between coaxial parts of the shank tool in the direction of rotation and in the axial direction. The coupling system includes a holding fixture formed in a first part for a centering extension provided on a second part to be connected, a drive device, and a clamping device which can be actuated externally by an adjusting m ~:~Mt
device and with which both parts can be pressed against each other through a prop ring surface pairing. The clamping device includes a connecting rod that is mounted symmetrically like a pendulum in the first part and that extends into a coaxial recess in the second part and forms a conical section there, through which the connecting rod can be placed under tension by the adjusting device braced on the second part. This generates pure axial tension which can be introduced, through a large, ring-shaped flat brace, without transverse force into the shank parts to be coupled.
4814573 ELECTRICAL DISCHARGE MACHINING APPARATUS WITH EXCHANGEABLE ELECTRODE REFEED CARTRIDGE John M Check, William L Clayton, Frederick L Fitts, Thomas Walser assigned to Ex-CeU-O Corporation An electrical discharge machine including a pick-and-place system for transferring electrode refeed cartridges from a storage turret to an EDM work station from either one or two indexable turrets. A plurality of equally spaced electrode cartridge assemblies are each removably mounted on each turret by magnets and guide pins. A slide assembly is vertically positioned between a cartridge assembly load and unload elevation and an EDM work station elevation. The slide assembly includes a movable connector plug assembly selectively driven by an EDM cylinder fixed on the slide assembly. The connector plug assembly supplies refeed cylinders on a slide mounted cartridge assembly and vertically reciprocates a power connector receptacle and drive head on such cartridge assembly. The
