  • Patent number: 9561537
    Abstract: Shown is a method for manufacturing horizontal directional drilling pipe having internally and externally upset pipe ends. The forging is done by heating the green tube ends and applying pressure using a closed die hydraulic forging press to form the upsets. One end of a steel tube is worked by upsetting and pressing to form an external upset portion having an outer taper being shaped by upset forging. That portion is then pressed by an internal upset die so as to displace the outer taper to an internal upset portion having an inner taper. Internal upset forging is then carried out by an internal upset die to produce the finished part. The process allows the manufacturer to produce a thicker upset horizontal directional drilling pipe, where the ratio of the outside diameter to the inside diameter of the upset can be on the order of 3.5, or even greater.

    Abstract: A hard disk drive with a multiple disk stack normally utilizes disk separator plates near the disk surfaces to reduce wind induced vibrations in the disks and the read/write heads. The manufacturing methods currently used to make these separator plates, metal casting and machining, or injection molded plastic, or extruding and machining, or cold forging tends to be expensive and creates unwanted weight and bulk without the desired precision. Stamping disk separator plates from metal provides exceptional dimensional control at reduced cost, but cannot readily provide the thicknesses required. Stamping and extruding the offsets, or stamping and folding the offsets, is a manufacturing process that provides the required dimensions for the offsets, and dimensional control and reduced cost.

  • Patent number: 8572843
    Abstract: A method and a manufacturing line allow for the manufacture of piston blanks of dimensions close to the final dimensions, which in the course of subsequent finish-machining need only be machined with removal of material to a small degree. A piston shaft of the piston blank is produced by backward extrusion. At least one hollow throat element is already produced at the piston blank by an upset-forging operation. For this purpose, a special forging tool is provided, which, after the manufacture of the piston shaft, takes effect on the piston blank in such a way that at least one hollow throat element is formed at the latest at subsequent forming of the piston base. In this way, a perceptible reduction is achieved in the weight of a piston in relation to conventionally manufactured forging pistons.

  • Patent number: 8544310
    Abstract: A forged product having thick end parts, and a thin part between the thick parts, is formed by extruding a forging stock such that the cross section of the forging stock varies along the direction of extrusion, wherein in any cross section in a direction perpendicular to the direction of extrusion, the forging stock has two thick end parts, a thin part intermediate the end parts and transitional parts with varying thickness between the thin part and each of the thick end parts; cutting the forging stock in the direction perpendicular to the direction of extrusion to form cut portions; and forging each of the cut portions such that the thick end parts of the cut portions form the thick end parts of the forged product and the thin part of the cut portions forms the thin part of the forged product.

    Abstract: A method for manufacturing a contact terminal including a contact portion that slides against a surface of a conductive contact plate. The manufacturing method includes forming a projection in a metal plate by performing a drawing process, wherein the projection projects in a thicknesswise direction of the metal plate and has a larger diameter than the contact portion. The manufacturing method further includes forming the contact portion from the projection by performing a contraction pressing process at least once on the projection so that the diameter of the projection gradually decreases, while the height of the projection remains the same or decreases in a stepwise manner.

  • Publication number: 20130143690
    Abstract: The present invention provides a golf club improved in ball hitting sound and ball hitting feeling and its manufacturing method. First, low-carbon steel is subjected to press processing of hot forging to form portions of irregularity on the face on a side of a hitting surface. Then, when there are projecting portions in the portions of irregularity, only the projecting portions are subjected to press processing of cold forging to crush the projecting portions to be flat. Then, the surface is slightly smoothed by machining to be flat and crystal grains at the portions of irregularity and the area therearound are pressed to be fined, thereby enhancing the hardness and forming fiber flows parallel to the hitting surface. A part of the hardened face becomes harder than the hardness of a base material before press processing by 10% or more within a range of 1 mm in a depth.

  • Patent number: 8382601
    Abstract: A method of manufacturing fastenings or fasteners with radial outer contours, especially screws or threaded bolts, made of solid metal is performed by a device. The method manufactures the fastenings or fasteners preferably on a multi-stage press. Several recesses running in an axial direction at a fixed radial distance are formed in the shank-shaped section of a blank. The prefabricated blank with the recesses is inserted into a multi-part split mold within a multi-stage press, whose die stocks have an inner profiling forming the outer contour, and are opened in the starting position, that at the places where the die stocks are opened, there are the recesses. During the closing movement of the die stocks, at least one radial outer contour is pressed on the shank-shaped section of the blank by radial action of forces, with the recesses preventing material from getting between the die stocks during the pressing process.
