  • Patent number: 9700925
    Abstract: The embodiments herein provide a hydrostatic backward extrusion system that utilizes hydrostatic pressure to produce products with desired cross sectional profile based on backward extrusion process. The system comprises a container, a plunger, fixed-punch, and a billet chamber. The billet material is placed inside the billet chamber. The empty space between the billet chamber and the billet material is filled with a high pressure fluid. Sealing is done at appropriate places to prevent leakage of fluid during the extrusion process. The plunger is moved down to create pressure on the fluid. Due to hydrostatic pressure, the billet material flows into the annular space between the container and the fix-punch. The design of head profile, inner and outer radius of fix-punch allows the billet material to flow smoothly into the annular and forms an extruded product.

  • 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.

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: 8328075
    Abstract: The invention provides methods of superplastic forming and diffusion bonding and a gas inlet tube that facilitates the methods which produce structures that are substantially mark off free. Methods include disposing a sealed pack into a die having a patterned surface and an opposite surface; applying a first pressure within the die around an outside of the pack; applying a second pressure within the pack, the second pressure exceeding the first pressure; and forming the pack by superplastic deformation into a diffusion-bonded structure. Further, a gas inlet tube is provided having an inner tube and an outer tube, where the outer tube is weldable to the pack in a gas tight seal.

  • 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.

  • Publication number: 20120283052
    Abstract: An embodiment of the invention provides a monolithic lacrosse stick handle having a first portion, a second portion, and a transition portion disposed between the first and second portion. The first portion has a first cross-section of a first shape. The second portion has a second cross-section of a second shape. The second shape is different from the first shape. Over the transition portion, the cross-sectional shape of the handle transitions from the first shape to the second shape. The handle can be integrally formed from a malleable material. The handle can have varying cross-sectional areas (e.g., wall thicknesses) along its length. A further embodiment provides a lacrosse stick handle that changes in direction, rather than defining a single longitudinal axis as in traditional handles. The nonlinear handle can have, for example, a linear main portion, a curved intermediate portion, and a linear dowel portion.

  • Patent number: 8303729
    Abstract: A creep forming tool modifies the shape of an aircraft component in the form of a wing skin portion. The tool includes a shaped surface defined by removable rib boards. The component is forced against the shaped surface, via a reusable intermediate plate. The shape of the shaped surface may be adjusted, if necessary, by replacing the rib boards with boards of a different shape.

  • Patent number: 8281630
    Abstract: The invention has as its object to perform hydroforming so that no buckling or wrinkles remain at a hydroformed product with a long expanded region and comprises performing a first step of raising the internal pressure in a state with the metal tube fixed in position at the two ends or a state applying axial pushing actions of 10% or less of the total amount of axial pushing action, then applying axial pushing actions while holding the internal pressure at a constant pressure so as to expand the metal tube near the ends, then performing a second step of raising only the internal pressure without applying any axial pushing action so as to thereby expand a center of the metal tube, then performing a third step of lowering only the internal pressure to the value of the constant pressure without applying any axial pushing action, then repeating the first to third steps one or more times, then raising the internal pressure in the state not applying any axial pushing action or applying an axial pushing action of 10

  • Patent number: 8127582
    Abstract: Methods and devices provide for high velocity forming of medical device casings. The high velocity forming may be produced by creating a pressure wave within a liquid contained by an enclosure. A die and a workpiece adjacent to the die are in the path of the pressure wave within the enclosure and the pressure wave forces the workpiece to conform to the contours of the die. Objects may be adhered to the die to provide for customized contours. Trimming features may be included within the enclosure to trim excess material from a formed workpiece as an integral part of the forming process. Various other features may also be provided within the enclosure including a diffuser to disperse the pressure wave. The workpiece may be of various forms including flat sheet stock.
