  • Patent number: 10300519
    Abstract: A manufacturing method of a press-formed article includes arranging a member to be pressed between first and second dies, and relatively moving the first and second dies so as to approach each other, thereby press forming to a portion to be pressed so that a height of the portion to be pressed decreases. In the press forming step, while first bent portions in a pair each bent in a protruded shape toward the second die on the portion to be pressed are held by groove-shaped holding portions in a pair separated from each other on the second die, a second bent portion bent in a protruded shape from a position between the first bent portions toward the first die on the portion to be pressed is pressed and deformed by a pressing portion of the first die.

  • Publication number: 20190099987
    Abstract: Provided is a strand board with improved strength and water resistance. Reduction in productivity is prevented and characteristics of the strand board can be varied as desired while achieving certain strength and water resistance of the strand board. A strand board B is formed by stacking and laminating five strand layers 1 each formed by a large number of strands 5. The strand board B has substantially constant density distribution in the lamination direction of the strand layers 1. Three of the five strand layers 1 of the strand board B are high-density strand layers 1a having a higher density than the other strand layers 1, and the other strand layers 1 are low-density strand layers 1b.

  • Publication number: 20180361461
    Abstract: 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.
