| 20090120155 | Shaping Tool and Methods of Using the Same - Disclosed are a shaping tool and a method of using the shaping tool, capable of applying a sufficient compressive stress to a shaping member to prevent an excessively high tensile stress from being imposed on the shaping member so as to achieve an extended usable life even if the shaping member is made of a hard and brittle material. The shaping tool comprises a shaping member, a pressure-applying member surroundingly fitted onto the shaping member, a collet chuck surroundingly fitted onto the pressure-applying member, and a casing surroundingly fitted onto the collet chuck. The pressure-applying member has a plurality of outer peripheral slits and a plurality of inner peripheral slits, which are circumferentially arranged in alternate relation and at even intervals. The collet chuck has an externally-threaded portion at an upper or lower end thereof, and a taper surface formed in an outer peripheral surface thereof to have a diameter which gradually decreases toward the externally-threaded portion. The casing has an inner peripheral surface formed as a taper surface in surface contact with the taper surface. The collet chuck is adapted to be reduced in diameter by fastening a nut disposed above or below the casing to the externally-threaded portion, so as to apply a compressive stress to the shaping member. | 05-14-2009 |

| 20100281941 | Core Rod Forging for Precise Internal Geometry - A forging die tool set defines a cavity and includes a core rod in the cavity for shaping a void in a work piece. The core rod extends in a direction in which the work piece is introduced, compressed, and ejected from the cavity. The core rod includes an upper portion and a lower portion. The upper portion has a cross sectional shape that forms a certain shape in the work piece and a radially tapered section that tapers toward the lower portion of the core rod. The lower portion also has a cross sectional shape that forms a certain shape in the work piece, and the cross sectional shape of the upper portion differs from the cross sectional shape of the lower portion, the lower portion being a more wear resistant shape characterized by larger radii and the upper portion being a finishing shape with smaller radii for shaping the final form of the forged work piece. | 11-11-2010 |
| 20150020566 | FORGING DEVICE FOR THE PRODUCTION OF A PISTON BLANK, AND METHOD FOR THE PRODUCTION OF THE PISTON BLANK BY MEANS OF SAID FORGING DEVICE - A forging device for producing a piston blank has a forging mold that has an essentially cylindrical cavity matching the radial outer surface of the piston blank, a forging base delimiting the cavity, and a central die consisting of a mandrel that has a conically tapering extension which is mounted on the mandrel and the shape of which matches the inner surface of the piston blank. In order to form the radially outer surfaces of the piston slipper walls and a peripheral cooling pocket located radially outside the slipper walls in the piston head, the forging device has two lateral jaws which are mounted in the forging device so as to be movable at an angle to the longitudinal axis of the forging device. | 01-22-2015 |
| 20160059295 | METHOD AND PRESS FOR PRODUCING SHEET METAL PARTS THAT ARE HARDENED AT LEAST IN REGIONS - A method for producing a sheet metal part with a press includes the steps of heating a sheet metal blank at least in regions to a above the austenitizing temperature Ac3, inserting the heated sheet metal blank into a forming tool station of the press, hot forming the sheet metal blank to the sheet metal part in the forming tool station, during which the press performs a closing movement, holding the forming tool station closed for a first holding time and cooling the formed sheet metal part during the first holding time, transferring the formed sheet metal part into a second tool station, hardening at least regions of the sheet metal part by cooling in the second tool station within the at least one second holding time, wherein the forming tool station during the closing movement of the press from an upper reversal point to a lower reversal point is moved relative to the press by at least one elastic actuating element so that the hot forming is terminated and the step of holding the forming tool station closed starts before the press reaches the lower reversal point. | 03-03-2016 |

| 20080302163 | Formation Tool for a Punching Machine - A formation tool is used for deforming sheet metal on punching machines. The formation tool has an upper or top die tool and a lower or bottom die tool. Toward the top die, there is an upper mold insert movable relative to a holding-down device, and toward the bottom die, a lower mold insert movable relative to a stripper plate. The deformation of the metal sheet is effected upward with respect to a punching stroke plane. The formation tool has a lifting device for aiding in lifting the lower mold insert from an initial position which is at or below the punch stroke plane before a deforming operation, to a level above the punching stroke plane. | 12-11-2008 |

| 20080307849 | Method And Apparatus For Forming Microstructures - A method of micro forming an array of microstructures comprising: advancing a punch having an array of protrusions ( | 12-18-2008 |
| 20090071219 | APPARATUS AND METHOD FOR FORGING PREMIUM COUPLING BLANKS - A method and apparatus for forging a tubular forging stock to produce a forged product, preferably a premium coupling machining blank. The apparatus includes a holding die assembly defining a holding cavity for the forging stock and a press die apparatus including opposed first and second press dies movable within the holding cavity to forge the forging stock to produce the forged product. The holding die assembly may include opposed first and second holding dies defining respective portions of the holding cavity, wherein the holding dies are selectively relatively movable between a closed position for forging the forging stock and an open position for removal of the forged product. Alternately, the apparatus may include a knockout mechanism for dislodging the forged product from the holding cavity. Further, the apparatus may include a mechanism for controlling finning between the first and second press dies while the forged product is being produced. | 03-19-2009 |
| 20110209517 | PRODUCTION EQUIPMENT FOR PRODUCING CORRUGATED FIN - The corrugated fin production equipment is capable of easily separating a corrugated fin having high ribs from a die after forming the ribs. The corrugated fin production equipment comprises: a lower block; an upper block being moved to and away from the lower block; the die being provided to the lower block and having a concave section; a punch being inserted into the concave section so as to form the rib when the lower block and the upper block are closed; and a movable die constituting a part of the die including the concave section, the movable die being upwardly moved above other parts of the die so as to lift a part of the corrugated fin, in which the rib has been formed, from the underside after the lower die and the upper die are closed to form the corrugated fin. | 09-01-2011 |
