  • Patent number: 9192980
    Abstract: A method for manufacturing a screw is disclosed where a blank is rolled between two rolling dies. In each rolling die a rolling profile has been formed that comprises a host of elongated depressions. The rolling die has a first and a second end which are spaced apart from each other in the direction of rolling. During rolling, the blank is moved relative to the die from the first end in the direction of the second end. The mean pitch of the center lines of the depressions, which pitch is defined as the quotient of the changes in the positions of the center line in the direction across or parallel to the direction of rolling, in a region of the first end of the rolling die differs from the mean pitch in a region of the second end of the rolling die.

  • Patent number: 9108359
    Abstract: The invention discloses a method for prevention of porosity in composite material parts (1), which is applied when the curing stage of the part (1) is being carried out on a female tool (2). In the curing stage, an adhesive (4) is placed on at least one of the areas of the radii (5) of the composite material part (1), so that the possible subsequent appearance of porosity in said areas of the composite material part (1) is prevented. Thus, the adhesive (4) acquires the fluidization temperature before the resin of the composite material and it is displaced filling the holes generated during the placement of the part (1) on the female tool (2), in the area of the radii (5) of the part (1), during the coupling between the part (1) and the female tool (2).

    Abstract: A broaching apparatus includes a first tooth having a front face, a rear face opposite the front face, and a first cutting surface have a lobed shape extending along a first side of the first tooth between the front face and the rear face. A first interface defined between the first cutting surface and the front face is offset relative to a second interface defined between the first cutting surface and the rear face in a direction that is substantially perpendicular to an axis of tooth movement for broaching operations to provide tool clearance rearward from the first interface. A method of making a broach cutter is further provided.

  • Publication number: 20120151985
    Abstract: A gas spring mount and related method for metal forming dies includes a one-piece, split clamping ring having a generally ovate plan shape with two spaced apart axes of symmetry. A generally circular clamping portion extends around the first axis, and is shaped to receive a gas spring body therein. A hook-shaped end extends around the second axis, and is shaped to receive a tapered head mounting member therein. A resilient free end is located operably between the clamping portion and the hook-shaped end portion, whereby tightening of the mounting member shifts the hook-shaped end outwardly and the free end inwardly to constrictingly pull the clamping ring securely against the gas spring body, and contemporaneously attach the assembly to an associated die member.

    Abstract: A guided keeper assembly and method for metal forming dies includes a base having a mounting face, at least one marginal fastener aperture to detachably mount the base to an associated die shoe, and a central guide aperture. A guide pin with a cylindrically shaped body portion is closely received in the central aperture of the base. A first end of the guide pin has an enlarged head to positively limit travel between the die shoe and die pad, and an opposite second end with a generally flat terminal shoulder configured for close reception in a blind hole in the die pad. The shoulder has a fastener aperture extending perpendicularly therethrough at a location spaced radially offset from the central axis of the guide pin.

  • Patent number: 8037727
    Abstract: A non-planar sputter target having differing crystallographic orientations in portions of the sputter target surface that promote more desirable deposition and density patterns of material sputtered from the target surface onto a substrate. A closed dome end of the sputter target is comprised of a first crystallographic orientation and sidewalls of the sputter target are comprised of a crystallographic orientation different from that of the dome. The sputter target is formed, preferably by hydroforming or other metal working techniques, in the absence of annealing. The hydroforming manipulations result in the different crystallographic orientations while minimizing, or ideally omitting, the application of heat. Quick and cost effective non-planar sputter targets that are easily repeatably producable are achievable as a result.

    Abstract: A flaring body has first and second opposing ends. A perimeter surface intersects the first end, and a flaring surface is located between the perimeter surface and the second end. The perimeter surface has a first cross-sectional profile with a first area, and the flaring surface having a second cross-sectional profile with a second area less than the first area. The perimeter surface and the flaring surface are joined by an inside, rounded corner. A crimping body has a top surface and an opposing bottom surface, and an interior surface that forms defines a passageway that connects said top and bottom surfaces. The interior surface has a third cross-sectional profile with a third area larger than the first area. The flaring body is slidably captureable in the passageway. The interior surface further has a crimping channel that extends along at least a portion thereof and terminates at the bottom surface.
