Abstract: Disclosed is an apparatus for manufacturing a long-neck flange comprising: a pipe support bar for supporting the inside of a pipe, the pipe support bar being rotatable; a rotatable pressurizing device connected to the pipe support bar for simultaneously rotating, pressurizing, and conveying the pipe with one end fixed thereto; a face roller for contacting a cross section of the pipe support bar to form a flange surface; a curvature roller positioned at the outside of the pipe for giving a curvature to the flange part; and a circumferential roller positioned at the outside of the pipe in the circumferential direction so as to form the width of the flange part.

Abstract: The present disclosure is directed to feedstock barrels comprising thermally and electrically insulating films configured to be adjacent to a feedstock sample when it is loaded in the barrel for the process of shaping metallic glasses by rapid capacitor discharge forming (RCDF) techniques.

Abstract: A method of manufacturing a blank which uses direct electric heating includes: pressing electrodes on both sides of the blank and heating the blank by applying current to the blank; hot-forming the heated blank; trimming the formed blank; and loading the trimmed blank. An apparatus for manufacturing the blank includes a pair of first electrode units on both surfaces of a side of the blank to press the surfaces, a pair of second electrode units on both surfaces of the other side of the blank, a pressing unit pressing the first electrode units or the second electrode units on the blank, a cooler cooling portions around the first electrode units or the second electrode units, and a power supply control unit heating the blank up to a predetermined temperature.

Abstract: A crimping method including the steps of: holding a workpiece comprised of a main body disposed around an outer circumference of a tubular shell in a first die; placing a second die for wrap crimping at a position facing the first die across the workpiece and moving the second die towards the first die to press the rim of the shell and plastically deform the rim to form a wrap crimped part; and bringing hot crimping-use electrodes arranged at sides of the shell, in a state holding the workpiece between the first die and the second die, into contact with side surfaces of the shell to apply current between the electrodes and the first die and make a thin-walled part to generate heat by resistance heating to thereby form a hot crimped part.

Abstract: Provided is a wire rod for an I-type oil ring, which includes right and left rail portions and a web portion connecting the rail portions, which has an oil hole or a molten through hole formed in the web portion, and which has a circumscribing circle diameter of 10 mm or less in its transverse contour. The molten through hole has such a remolten portion formed on its exit side as encloses the exit of the molten through hole. The remolten portion exceeds such a molten portion in the transverse section along the center of the molten through hole as is formed in the molten through hole, and is formed to have 200 ?m or less from the outer circumference of the molten through hole and 100 ?m or less in the depth direction of the molten through hole.

Abstract: An apparatus and method for heating and transferring a workpiece to a forming press for superplastic forming. The apparatus includes a heater assembly, having upper and lower heated platens, mounted to a frame. The heater assembly heats the workpiece to a predetermined temperature. A shuttle assembly operates to remove the heated workpiece from the heater assembly and transfer it to the forming press for forming.

Abstract: A method and apparatus for clinching metal sheets is disclosed. The apparatus includes a punch assembly for stamping indentations into stacked metal sheets and a die assembly for assisting in supporting the sheets during stamping of the indentations and for assisting in forming the indentations. The punch assembly, the die assembly or both in combination provide energy to at least a portion of the metal sheets prior to stamping. In turn, the energy elevates the temperature of the portion of the sheets such that the indentations can be more effectively formed in the portion and such that the sheets are fastened to each other with greater strength.

Abstract: A tungsten powder having a powder specific surface of 0.4 m2/g or more is hot-pressed at a temperature of 1,600° C. or more and then subjected to HIP at a temperature of 1,700° C. or more without capsuling, whereby a tungsten target for sputtering is manufactured that has a relative density of 99% or more and an average crystal grain size of 100 &mgr;m or less. This manufacturing method can manufacture, stably at a low cost, a tungsten target having such a high density and fine crystal structure as cannot be attained by the conventional pressure sintering method, and can greatly decrease the number of particle defects on a film produced by using such a target.

Abstract: A method of hot bending a generally straight wire blank of a material being brittle in cold condition into a wire element having straight end portions and coils formed therebetween. According to the invention the rod blank is hot bent without a mandrel by clamping the end portions of the rod blank by means of two clamping jaws. The rod blank is heated to a softening temperature in the central wire portion which is to form the coils of the finished wire element, while the end portions are kept at a lower temperature. During the bending process at least one of the clamping jaws is brought along a movement path adapted to the desired coil formation.

Abstract: Contact heater station mechanism for use in a thermoforming machine for particularly forming thermoplastic synthetic plastic and superplastic metal alloy sheets into shapes, such machines having a sheet transfer station, a heating station, and a forming station with relatively movable mold parts, and providing a circuit for sheet carrying carriages which index individually clamped sheets from one station to another cyclically in a path of travel. The mechanism includes platens mounted on the machine frame at the heating station to move toward and away from the path of travel of the carriages and sheets. A heater carrrier for elongate electrical resistance heaters carries a contactor plate, and is rigidly mounted to each platen in a manner to permit universal thermal expansion of the carrier and plate with respect to the platen.

Abstract: A forming method in which members are forced together at an interface by causing parallel currents to flow in adjacent conductors, thereby forcing the conductors toward each other in a direction generally normal to the interface.
