MANUFACTURING METHOD OF PRESS-MOLDED ARTICLE AND PRESS MOLDING APPARATUS
A manufacturing method of press-molded article of the present invention comprises a step of placing a member to be pressed in a press molding apparatus and a step of pressing a flat plate portion of the member to be pressed by bringing a first press portion and a second press portion closer to each other. A first opposing surface and a second opposing surface, while facing to each other, keep in contact with the flat plate portion during pressing. In the press step, a thick part is formed on the flat plate portion by allowing a part of a material of the flat plate portion to flow, in a press direction, into a thickened portion-forming section formed on the first opposing surface. The second opposing surface is moved to the press direction as the flat plate portion is pressed by the first press portion and the second press portion.

Formed member and manufacturing method thereof
A formed member is provided which can be manufactured at a low cost, which has excellent dimensional accuracy, which has excellent axial crushing properties and three-point bending properties, which has excellent bending stiffness and torsional stiffness, and which is suitable for use in a component of an automobile. The formed member (20) has a reinforcing member (35) which is joined by a weld (40) provided on a ridge portion (28). It is manufactured by joining a flat sheet blank and a flat sheet reinforcing member (35) by a weld (40) and performing bending so that the weld (40) becomes a ridge portion (28).
Method for encasing a body of an exhaust gas system
A method for encasing a body of an exhaust gas system with a housing which is wound around the body. Using a winding method, the body is placed in a loop formed by a belt-shaped conveyor element that can be driven in a conveyor device, wherein the conveyor element is seated against the outer casing face at a wrapping angle u of at least 270 degrees. Starting with a first edge, the metal strip is then introduced in a conveyor device between the body and the conveyor element, is drawn into the gap between the body and the conveyor element and is bent around the body until the body is encased at least twice by the metal strip.
Manufacturing method of press-formed article and press forming apparatus
A manufacturing method of press-formed article according to the present invention includes a step of placing a flat plate member between a first die and a second die, and a step of causing a first press portion and a second press portion approach each other, thereby pressing the flat plate member. In the step of placing, the flat plate member is placed so that a first main surface and a second main surface align with a vertical direction. In the step of pressing, the flat plate member is vertically pressed by causing the first press portion and the second press portion to approach each other in the vertical direction, and a thick portion is formed on the flat plate member by causing a part of a material of the flat plate member in the vertical direction to flow into a thickened portion-forming section formed on a first opposing surface.

AERODYNAMICALLY ACTIVE STIFFENING FEATURE FOR GAS TURBINE RECUPERATOR
A method of manufacturing a recuperator disposed in the exhaust duct of a gas turbine engine includes forming a first leading recess adjacent a leading edge of a first thermally conductive sheet and forming a second leading recess adjacent a leading edge of a second thermally conductive sheet, the first and second thermally conductive sheets forming components of a recuperator plate. The first leading recess of the first thermally conductive sheet is mated with the second leading recess of the second thermally conductive sheet, and then the first and second leading edges are joined thereby forming a recuperator plate. The first and second leading recesses form a trough extending along a leading edge of the recuperator plate in a direction substantially parallel to a longitudinal axis of the recuperator plate.
Producing composite fiber/metal workpieces
Methods, systems and apparatus for producing composite fiber/metal workpieces. In one aspect, a method includes locating a metal workpiece on a workpiece support of a machine tool, processing the metal workpiece located on the workpiece support to produce one or more shaped features on the metal workpiece, fitting a fiber fabric to the metal workpiece in a region of the shaped features, and connecting the fiber fabric to the metal workpiece in at least one of a non-positive-locking connection or a positive-locking connection to produce a composite fiber/metal workpiece.
