  • Patent number: 10875072
    Abstract: A method of forming a material using a supersonic fluidic oscillator in a superplastic forming process and a related system. Pressurized gas, at a baseline pressure, is applied to a surface of the material when the material is received within a cavity of a forming tool. Pressure fluctuations, relative to the baseline pressure within the tool cavity, are created with a supersonic fluidic oscillator. Each pressure fluctuation (i) deforms the material and (ii) subsequently allows for a partial stress relief of the material during the forming process.

  • Patent number: 10137491
    Abstract: By the control of a controller, a gas is supplied into a metal pipe material from a gas supply part so as to expand a part of the metal pipe material in sub-cavity parts, and then a driving mechanism is driven such that expanded parts of the metal pipe material are pressed by an upper die and a lower die to form flange parts. In addition, by the control of the controller, a gas is supplied into the metal pipe material after the formation of the flange parts from the gas supply part so as to form a pipe part in a main cavity part. In this manner, the controller controls the gas supply part and the driving mechanism, and thus flange parts and a pipe part having a desired shape can be easily formed.

  • Patent number: 9579711
    Abstract: A forging apparatus and method is disclosed in which a punch 260 is held in a press 210, 220 and propelled towards a billet 250 by a ram 240. The ram 240 is separate from the punch 260. Thus, any axial misalignment between the ram 240 and the press 210, 220 in which the billet is held, for example due to the extremely high loads involved, has no affect on the direction and position of the impact force the punch 260 transmits to the billet 250. This helps to prevent unwanted forces and bending moments in the punch 260, thereby preventing breakage of the punch 260.

    Abstract: A method for forming a piece of a sheet metal is performed by positioning a consumable body, made of metal, proximate to the piece of the sheet metal. The consumable body is rapidly vaporized, and the gas pressure generated thereby is directed into the piece of the sheet metal. This results in acceleration of the piece of sheet metal, and it is collided into a stationary body at a velocity, generally in excess of 200 m/s. Depending upon the type of stationary body, the piece of sheet metal is deformed into a predetermined shape or is welded onto the stationary body. The vaporization is accomplished by passing a high current of electricity into the consumable body. The effect of the vaporized metal may be augmented by additional components in the consumable body.

    Abstract: An apparatus and method are provided for the simultaneous forming of a plurality of shaped articles from plural sheet metal blanks. First and second sheet metal blanks are arranged between upper and lower forming dies, and a nozzle body having a generally diamond-shaped cross-sectional profile, transverse to an insertion direction, is inserted between the sheet metal blanks. When the forming tool is closed, upper and lower sealing surfaces of the nozzle body press the first and second sheet metal blanks, respectively, against sealing beads that are arranged one each within peripheral areas of the upper and lower forming dies. Opposite side edges of the nozzle body converge one toward the other so as to facilitate forming a seal along each of the side edges of the nozzle body. A pressurized fluid is introduced via the nozzle body for forming the sheet metal blanks within a die cavity.

  • Patent number: 8499599
    Abstract: A laser nanoforming system and method for forming three-dimensional nanostructures from a metallic surface. A laser beam is directed to hit and explode an ablative layer to generate a shockwave that exerts a force on the metallic surface to form an inverse nanostructure of an underlying mold. A dry lubricant can be located between the metallic surface and mold to reduce friction. A confinement layer substantially transparent to the laser beam can confine the shockwave. A cushion layer can protect the mold from damage. A flyer layer between the ablative layer and metallic surface can protect the metallic surface from thermal effects of the exploding ablative layer. The mold can have feature sizes less than 500 nm. The metallic surface can be aluminum film. The dry lubricant can be sputtered Au—Cr film, evaporated Au film or a dip-coated PVP film or other dry lubricant materials.

  • Patent number: 8490455
    Abstract: This aims to provide a press-apparatus mold capable of improving the yield of a blank while preventing wrinkles and cracks in a finished product, and an open-drawing method according to the press-apparatus mold. Within a range corresponding to the excess thickness portion (6) of a blank (4), the width of a punch (3) is gradually enlarged toward the end of the punch (3), thereby to curve boundaries (or the punch ridgelines (3d and 3e)) formed by the upper face (3a) and the side faces (3b and 3c) of the punch (3), toward the end of the punch (3) and to the widthwise outer sides of the punch (3). At the same time, the width of the recess (1a) of a die (1) is gradually enlarged toward the end of the recess (1a), thereby to curve a drawing profile (8) set by the punch (3) and the die (1), toward the ends of the punch (3) and the recess (1a) and to the widthwise outer sides of the punch (3) and the recess (1a).

  • Publication number: 20120292126
    Abstract: A method for processing at least one surface element wherein at least one layer of a deformable, medium-tight material is respectively attached to each side of the surface element, inserts the surface element and attached deformable layers between at least two molding tool parts and applies a pressure to at least one area of a surface section of the inserted surface element in response to a predetermined shaping temperature by introducing a medium between one of the deformable layers and a first molding tool part. The pressure acts directly against the deformable layer so that the surface element together with the deformable layers is shaped into at least one adjacent cavity of a second molding tool part due to the pressure created. A possibility of molding surface elements, which can currently not be shaped via gas pressure, into complex geometries, namely into spatially bent geometries, is created with this method.
