  • Publication number: 20220274150
    Abstract: A method for manufacturing a press-formed product suppresses occurrence of a forming defect such as a crack in a starting material during press forming, and also suppresses occurrence of problems when transferring a starting material during press forming. 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. 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. 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.

  • Patent number: 11224908
    Abstract: A cutting method using a stamping press according to the present disclosure is a method to cut a workpiece that is configured from a first metal sheet and a second metal sheet joined at a weld portion and that has a heat-affected zone around the weld portion, in which the workpiece is cut using a punch. The punch includes a flat portion and a projecting portion projected more toward the workpiece than a flat portion of the punch. The workpiece is positioned with respect to the punch at a position such that the projecting portion starts cutting at least at one out of the heat-affected zone or the weld portion before the flat portion cuts the workpiece. The workpiece is then cut by moving the punch and a die relative to each other in this state of positioning so as to shear across the weld portion on the workpiece.
