摘要： A method for manufacturing a press-formed product is provided that can suppress occurrence of a forming defect such as a crack in a starting material during press forming, and can also suppress occurrence of problems when transferring a starting material during press forming. In the method for manufacturing a press-formed product, a manufacturing intermediate is formed by forming, in a flat-sheet shaped blank sheet, a planned outline portion including an undulating shape which is used for forming an outline of an outer circumferential portion of a press-formed product. Further, the flat shape of the blank sheet is maintained in a region from the planned outline portion toward the center of the manufacturing intermediate, or an intermediate stretch-formed portion having a predetermined intermediate forming height is formed in the manufacturing intermediate in the region. Furthermore, a through-hole is formed by piercing a flat portion at which the flat shape is maintained or a stretch-formed-side top portion of the intermediate stretch-formed portion. In addition, the flat portion after the through-hole is formed therein is formed into a stretch-formed portion of a predetermined height, or the intermediate stretch-formed portion after the through-hole is formed therein is formed into a stretch-formed portion of a predetermined height that is greater than the intermediate forming height.

摘要： An automobile hood 1 has joints 20 that join an inner panel 2 and an outer panel 3. The inner panel 2 includes, for example, units 8 and 9 arranged in plurality in an aligned relationship in a cross direction X and arranged in plurality in an aligned relationship in a longitudinal direction Y. The plurality of units 8 and 9 include a plurality of joint-equipped units in which the joint 20 is provided. A predetermined first form or second form is provided in the automobile hood 1. In the first form, in some of the joint-equipped units, namely, joint-equipped units 84, 89, and 9, the joints 20 are arranged in an arrangement including a predetermined pattern P1, and in the remaining joint-equipped units 81, 85, 86, 810, 811, and 812, the joints 20 are arranged in an arrangement including a part of the predetermined pattern P1. In the second form, in each of the joint-equipped units 8 and 9, a plurality of the joints 20 are arranged in an arrangement including the predetermined pattern P 1.

摘要： A method of manufacturing a press-formed product includes: capturing the amount of warp in a sheet to be pressed separately for each sheet; and using a die 6, a punch 7, and a movable mold part to press-form the sheet into a press-formed product. During press-forming, the initial position of the movable mold part 9 relative to the die 6 or punch 7 is controlled depending on the amount of warp in the sheet.

摘要： An automobile panel is provided in which sufficient surface rigidity is secured in an outer panel even at a location where a space between an inner panel and an outer panel is narrow, while also achieving a reduction in weight. An automobile panel 1 has a sheet-shaped outer panel 2 and a sheet-shaped inner panel 3, and an interior member 30 arranged in a space S between the inner panel 3 and the outer panel 2. The interior member 30 is an elongated member that extends in a first direction D1 along the outer panel 2, and includes a first end 41 that is one end in the first direction D1, and a second end 42 that is another end. The first end 41 has a first connecting portion 45 which is connected to the inner panel 3. The interior member 30 has a second connecting portion 46 that is connected to the outer panel 2, at a position that is separated from the first end 41 along the first direction D1.
