  • Patent number: 9038270
    Abstract: In a method of making a tubular body, material is pressed through a die of a forming tool into a first mold cavity disposed in downstream relationship to the die to produce a first end piece. A mandrel is then moved in a direction of the die to thereby displace the mold cavity in the same direction and to extrude a tubular center piece to adjoin the first end piece. The mandrel is then replaced by a mold having a second mold cavity to mold a second end piece to adjoin the center piece.

    Abstract: A pneumatic press with high slide acceleration and velocity is equipped with an arrangement trigger mechanism for holding the slide, upper die, and punch in place until air pressure force in tons is exerted against slide opposite the upper die and punch. When the trigger mechanism releases the slide, upper die, and punch in a short travel the velocity is very high. This will permit the punch to enter the part material at the strain rate of the material, thus eliminating burrs, reducing fatigue initiation sites on the part material surface where the punch goes through the material. Also will permit forming parts of uniform thickness, impact powder titanium to form sheet, and stamp parts against flat sheet of polyurethane with punch having the shape of the part.

    Abstract: A “negative creep” corrugated gasket of Shape Memory Alloy (SMA) for Bolted Flanged Connections (BFCs) operates under temperatures that are within the temperature interval of reverse martensitic phase transformation from martensite to austenite of the SMA. Gasket corrugation is shape-memorized to operating “swelling” at temperature of direct martensitic phase transformation from austenite to martensite of the SMA being compressed to obtain some quantity of residual contraction corresponding to stress-induced martensite formation. A free “swelling” of deformed gasket corrugation at operating temperature defines the “negative creep” effect of the gasket, and it is blocked by rigid flanges with appearance of reactive shape-recovering stresses between the gasket corrugation and flange surfaces. The reactive shape-recovering stresses have direction inverse to the direction of operating creep of the gasket providing leak-tight, multiple, automatic and continuous seal between the flanges of the BFC.

    Abstract: A needle (15) for a textile machine, in particular a felting needle or fork needle. A working section (17) extends along a longitudinal axis (16) and has a needle point (18). Adjoining the working section (17) are a lower shank section (20) and an upper shank section (25), both said shank sections extending coaxially with respect to each other along the longitudinal axis (16). Adjoining the upper shank section (25), there is provided a needle foot (30) that has a holding means (32) extending in a straight line in a transverse direction (31) transversely to the longitudinal axis (16). The diameter (E) of the upper shank section (25) is both greater than the diameter (D) of the lower shank section (20) and greater than the mean width of the holding means (32).

  • Publication number: 20100223973
    Abstract: A method of producing a metallic shell for a spark plug, including steps of preparing a first intermediate article by using a first die including a first large diameter cavity larger in diameter than a metal blank, a first small diameter cavity smaller in diameter than the metal blank, a curved tapered cavity between the first large diameter cavity and the first small diameter cavity, and an oil drain cavity between the first large diameter cavity and the tapered cavity and substantially same in diameter as the metal blank, wherein the metal blank is inserted in the first large diameter cavity and extruded to allow a configuration of the metal blank to conform to the first large diameter cavity, the oil drain cavity, the tapered cavity and the first small diameter cavity while being pressed by a punch, and preparing a second intermediate article by using a second die.

  • Patent number: 7761995
    Abstract: A gear wheel includes multiple helical toothings, each having a different helical angle. A pressing method for molding a gear wheel involves introducing a compactable material into a chamber of a pressing tool, compacting the material, exposing the helical toothings of the gear wheel, and removing the molded body from the pressing tool. A pressing tool for pressing, as one part, a gear wheel, includes a matrix, cylindrical first and second molding tool parts which can be translated along and then rotated about a longitudinal axis, and a driver coupled to the molding tool parts or driving them. The molding tool parts can be moved towards and away from each other and the inner surface of the matrix delimits the chamber and is shaped to allow a linear axial sliding movement of the compactable material relative to the matrix.

  • Patent number: 7730755
    Abstract: The present invention relates to a process of producing a permanent magnet, which includes extruding a preform to form a plate-shaped permanent magnet, in which the preform is extruded in such a way that a dimension of a cross section of the preform is reduced in an X-direction and enlarged in a Y-direction perpendicular to the X-direction. The present invention also relates to a plate-shaped permanent magnet formed by extruding a preform, in which the preform is extruded in such a way that a dimension of a cross section of the preform is reduced in an X-direction and enlarged in a Y-direction perpendicular to the X-direction, whereby the permanent magnet has a strain ratio ?2/?1 with respect to the preform in a range of 0.2 to 3.5, in which ?1 is a strain in the direction of the extrusion of the preform and ?2 is a strain in the Y-direction.

  • Publication number: 20100058826
    Abstract: Disclosed herein is a method of manufacturing a container for absorbing fluid shock or mechanical shock. The method includes preparing a raw material pipe, forming a coupling pipe by reducing a diameter of at least one side of the raw material pipe, and forming an inner circumference of the coupling pipe and bending it. Accordingly, a container body and a coupling pipe coupled to at least one side of the container body are integrated together, so that an additional process for coupling the container body with the coupling pipe is not required, and thus the cost of production is reduced.

  • Patent number: 7601232
    Abstract: Described herein are methods for forming titanium alloy tubes having an ?-? grain structure. The methods include the steps of hot-working a titanium alloy workpiece at a temperature below the ?-transus temperature of the workpiece and above the recrystallization temperature of the workpiece to produce an ?-? titanium alloy preform hollow. Subsequently, the ?-? titanium alloy preform hollow is flowformed, thereby forming a ?-? titanium alloy tube.

  • Publication number: 20080202190
    Abstract: A die having various features such as spring pockets and mounting provisions for a lifter bar that can be utilized to make a variety of dies. The dies may include pockets or other mounting features that provide for mounting replaceable plates that can be machined for mounting of die forming and cutting steels and other die components. The die shoe may include an array of pockets or blind holes for mounting nitrogen springs or the like for operation of forming steels and the like. One or more openings may be drilled in the replaceable plates above the pockets selected to receive nitrogen springs, with the remaining unused pockets being covered by the replaceable plate. The replaceable plate and pre-formed spring pockets thereby permit the die to be readily adapted for a particular die. The replaceable plates may be removed, and a replacement plate may be installed as needed for a new die.
