  • Patent number: 9630238
    Abstract: A workpiece is formed into a curved shape that has curvatures in the longitudinal and width directions required for a final closed cross-sectional shape. The formed workpiece is bent in a direction that left and right side wall portions approach each other by clamping the bottom portions between a punch and pad in a plate-thickness direction. A pair of flange portions are butted against each other while the formed bottom portions of the workpiece are placed on a pad; and a die cavity having the same shape as the final closed cross-sectional shape is defined between a support surface of the pad supporting the bottom portion and pressing surfaces of a pair of pressure cams pressing the left and right side wall portions. Then, the pair of flange portions are depressed toward the cavity using depressing portions of a second punch disposed above the pair of flange portions.

    Abstract: The invention relates to a method for producing hollow profile-members having a longitudinal flange, wherein a plate which is arranged between the stamp and the first die being preshaped by introducing a stamp into a first die to form an U-shaped profile-member having a first member and a second member, and wherein the U-shaped profile-member being shaped with a second die to form an O-shaped profile-member having a longitudinal flange. In one aspect, the plate is preshaped to form the U-shaped profile-member, a longitudinal flange member portion is shaped in at least the first member and the longitudinal flange member portion is constructed during the shaping of the U-shaped profile-member to form an O-shaped profile-member substantially in a shape-retaining manner to form a portion of the longitudinal flange.

    Abstract: Provided are a pipe which exhibits corrosion resistance against vapor of fuel such as gasoline, diesel oil, bioethanol or a biodiesel fuel, a method for manufacturing the pipe, and a steel sheet for manufacturing the pipe. A method for manufacturing a pipe having a bent portion which has excellent corrosion resistance against fuel vapor includes the steps of; preparing a steel sheet for manufacturing a pipe which is characterized by having a zinc-nickel (Zn—Ni) alloy layer where a nickel content is 4 to 16 at % on at least one surface of the steel sheet; forming the steel sheet for manufacturing a pipe into a tubular shape such that the Zn—Ni alloy layer forms an inner surface of the pipe, and applying bending to the pipe such that the elongation of the bent convex portion generated at the time of bending the pipe falls within 20%.

  • Publication number: 20130035609
    Abstract: Utilizing the technology and methods disclosed, the characteristics of flexibility and rigidity for intralumenal devices, including coaxial two piece devices such as stylet and needle sets, can be adapted by a physician or device manufacturer according to the type of procedure, the patient size and unique anatomical challenges of a given procedure. Rigidity and flexibility are actively controlled by the operator at predefined portions of a device through rotating the stylet within the cannula to bring about alignments of customized notches to impart target flexibility or rigidity profiles at specific spots on the device. The device operator is able to alter the relationship and orientation of specific notched and non-notched segments of either or both the stylet and cannula that are strategically located at said critical points along the length of the device.

  • Publication number: 20130004883
    Abstract: Provided is a novel high-nitrogen stainless-steel pipe which is not obtained with any conventional technique, the stainless-steel pipe having high strength, high ductility, and excellent corrosion and heat resistance and being obtained through size reduction of crystal grains and strengthening by slight plastic working besides formation of a gradient structure in which the concentration of solid-solution nitrogen continuously decreases gradually from the surface. Also provided are hollow materials of various shapes and sizes which are formed from the steel pipe and processes for producing the steel pipe and the hollow materials. An austenitic stainless-steel pipe is treated in a range of the temperatures not higher than the critical temperature for crystal grain enlargement of the steel pipe material to cause nitrogen (N) to be absorbed into the surface of the pipe and diffused into the solid phase, while minimizing the enlargement of crystal grains during the treatment.

  • Publication number: 20120260713
    Abstract: An apparatus for forming a duct includes a bending apparatus and a support apparatus. The bending apparatus includes a table, a cut off beam, and a leaf hinged to a forward edge of the table. The cut off beam is movable toward and away from the table to clamp or release a metal web being fed forward across the table and the leaf. The cut off beam repeatedly clamps the metal web to the table while the leaf pivots toward the cut off beam to form a duct section. The support apparatus includes a cross rod movable along pivoting support arms. As the metal web is bent to form the duct section, the support arms and the cross rod are moved to internally support the duct section.
