摘要： A method for reducing the number of sub-parts of a closed structure part and the number of steps for manufacturing the closed structure part is provided and, therefore, the closed structure part is efficiently manufactured. In the method for manufacturing closed structure parts, a punch 84 is moved in the pressing direction. A joint end 19, which is one of two joint ends of a blank 24, is bent using a pressing force exerted by a flange processing portion 102. The joint end 19 overlaps a joint end 21, which is the other joint end of the blank 24. The joint end 19 is made into a latch flange portion 20 for latching the joint end 21. At the same time, the blank 24 is pressed by using two press forming surfaces 96 and 97, and two shoulder portions 26 of the blank 24 are press-formed into predetermined shapes. In this way, the joint end 19 is made into the latch flange portion 20. The latch flange portion 20 latches the other joint end 21, and the latch flange portion 20 can be fixed to the joint end 21. Simultaneously, the two shoulder portions 26 can be press-formed into predetermined shapes.

摘要： Using a related-art die set for press forming to manufacture a metal component with a three-dimensional edge in a simple process causes cracking and wrinkling to occur. Consequently, a target shape of the metal component with a three-dimensional edge cannot be obtained. Thus, simplifying the manufacturing process and reducing the weight of products are very difficult to achieve at the same time. A method for manufacturing a metal component with a three-dimensional edge manufactures the metal component with a three-dimensional edge from a blank 10 as a raw material. The blank 10 is cut from a metal sheet and has a curve-shaped curved edge portion 15 having both ends. The curved edge portion, or further, the curved edge portion and part of the blank adjacent to the curved edge portion are processed into a three-dimensional shape by forming. The method includes a step of providing a bend formation line and a step of forming the three-dimensional shape. The step of providing the bend formation line serves as a first step and provides the bend formation line in the curved edge portion so that a bend radius of a section of a bent portion downwardly or upwardly bent along a curve of the curved edge portion is from 0.5 to 30 mm. The step of forming the three-dimensional shape serves as a second step following the first step, and processes the curved edge portion, or further, the curved edge portion and the part of the blank adjacent to the curved edge portion into the three-dimensional shape from the bend formation line as a start point by moving both end portions of the curved edge portion so as to reduce or increase a distance between both the ends.

摘要： A method for manufacturing a pipe with different diameters along a longitudinal direction that has a small diameter portion, a large diameter portion, and a diameter-changing portion provided between the small diameter portion and the large diameter portion and is formed by press forming a blank made of a metal sheet. The method includes a step of press forming the blank with a U-shape forming die into a U-shaped formed part and press forming the U-shaped formed part with an O-shape forming die set into a circular cross-section formed part. A length of a vertical wall of the U-shape forming die is longer than a length of a vertical wall portion of the U-shaped formed part. In the O-shape forming die set, a die mating line is inclined downwardly, and a ratio t/D of a sheet thickness t of the blank to a diameter D, which represents a diameter of a portion of the O-shape forming die set corresponding to the small diameter portion and a diameter of a portion of the O-shape forming die set corresponding to the large diameter portion, is 0.010 ≤ t/D ≤ 0.080. A circumferential compressive strain given by the following expression (1) is equal to or more than 0.5%: Circumferential compressive strain = (blank width in sheet width direction that becomes pipe circumferential direction - perimeter of die set)/perimeter of die set x 100(%).

摘要： The number of sub-parts of a closed structure part and the number of steps for manufacturing the closed structure part can be reduced and, therefore, the closed structure part can be efficiently manufactured. In a hemming press step, a punch 84 is further lowered, and a pair of flange portions 20 and 22 is inserted into a slit clearance 102. At that time, hemming prongs 28 are bent and, each of the hemming prongs 28 sandwiches the flange portion 22. Thus, the flange portion 20, which is one of the two flange portions, is joined to the other flange portion 22. At the same time, a pair of press forming surfaces 96 of the punch 84 presses a metal plate and performs press-forming on a pair of shoulder portions 26 of a blank 24 into a predetermined shape. In this way, the flange portion 20, which is one of the two flange portions, can be fixed to the other flange portion 22 using the hemming prongs 28 (hemming joint). In addition, the pair of shoulder portions 26 of the blank 24 can be press-formed into the predetermined shape.
