  • Patent number: 9021845
    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.

The flange width is increased without cracking and a decrease in the thickness. A stay material having a circumferential wall undulating in a waveform pattern is used. A circumferential length L (one round length along waveform pattern) of the outer periphery wall along the circumferential direction of the stay material is longer than a circumferential length L0 of a simple cylindrical circumferential wall having the same outer diameter (circumscribed circle) (L>L0). L?L0 is an excessive line length. Since the circumferential wall has the excessive line length, when the end of the circumferential wall is expanded to form the flange, the flange having a large diameter can be formed.

    Abstract: An ultrasonic impact treatment method for remediating metal sensitization including introducing ultrasound compression wave energy through ultrasonic mechanical impulse impacts into an area of sensitized metal in a workpiece. The ultrasound compression wave energy and impulse impacts impart compressive residual stress to the workpiece thereby decreasing tensile stresses in the sensitized metal and modifying the grain structure of the workpiece. These changes to the structure of the workpiece combine to slow the rate of enrichment of alloying elements at grain boundaries within the area of sensitized metal, cause intergranular diffusion of alloying elements in the area of sensitized metal, return a portion of alloying elements in the area of sensitized metal to solution and reduce or eliminate substantially straight intergranular paths through the workpiece.

  • Publication number: 20130220473
    Abstract: Apparatus and methods are disclosed whereby a propellant driven water stream is used in the formation of materials made from high tensile strength alloys. High pressure developed in liquid flowing through a tubular work piece is employed to achieve desired forms. The high pressure results from superposition of compression waves generated in the course of the impact of the liquid by products of propellant combustion.

  • Patent number: 8516866
    Abstract: A device for explosive forming of a tubular work piece includes a multipart explosive forming die, which defines a forming area having an inner surface corresponding to a final shape of the tubular work piece and a nozzle arrangement disposed adjacent to the forming area. The device also includes a plug for forming a seal by simultaneously deforming an end of the work piece and clamping the deformed end between the plug and a facing surface of the nozzle arrangement. In this way, the work piece itself contributes to the sealing of an internal explosion space. With insertion of new work piece blanks, and introduction of the plug during each individual forming process, new seals are produced in a convenient manner during subsequent forming processes. The device supports a simplified handling approach and integrates several functions into one working step, resulting in a shorter cycle times and cost-effective industrial production.

  • 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.

  • Publication number: 20130174627
    Abstract: A top head of a reactor pressure vessel is provided with a plurality of control rod drive mechanism (CRDM) penetration pipes arranged in a square grid-like pattern. The CRDM penetration pipes are joined by a tube support member disposed among them. The top head is placed on a tank and water is filled in an inner region of the tank and the top head. A travel apparatus moves a nozzle lifting/lowering apparatus to a predetermined location and a lifting/lowering mechanism is operated to lift a jet nozzle above the tube support member in the neighboring four CRDM penetration pipes. An ejection outlet of the jet nozzle is directed to a weld between one of the CRDM penetration pipes and the top head, and a water jet is ejected to start WJP. A nozzle turning mechanism turns the jet nozzle, and WJP is executed sequentially to the four CRDM penetration pipes.

    Abstract: A tool for modifying a workpiece by either trimming or joining the workpiece. The tool is an electro-hydraulic tool that uses a pulse transmitted through a liquid to trim a workpiece or to join two thicknesses of metal together. A method of trimming the workpiece includes the steps of providing a high voltage discharge in a liquid that drives a workpiece into engagement with a cutting edge of a tool steel insert. A method of joining two or more thicknesses of metal together includes the step of creating a high voltage discharge through an electrode that accelerates one panel or thickness of metal into a second panel that is held stationary by a backing plate while the first thickness of metal is accelerated into the second thickness of metal.
