摘要： The present invention provides a plate-shaped workpiece positioning structure for hot press forming that, upon executing a hot press forming of a heated plate-shaped workpiece (16), positions the plate-shaped workpiece relative to a pair of press dies (10, 12, 14). The positioning structure includes (a) a first positioning opening (20b) and (b) a second positioning openings (22a, 22c). The first positioning opening is arranged in a center part of the plate-shaped workpiece, and engages with a first positioning pin (22b) provided on one (12) of the pair of press dies to position the plate-shaped workpiece. The second positioning openings are arranged between the first positioning opening and a predetermined outer peripheral parts (16a, 16b) of the plate-shaped workpiece, and are formed in an elongate shape that extends along a line connecting the first positioning opening and the predetermined outer peripheral part of the plate-shaped workpiece. The second positioning openings engage with a second positioning pins (22a, 22c) provided on one (12) of the pair of press dies. Thus, the plate-shaped workpiece is positioned in a circumferential direction about the first positioning opening of the plate-shaped workpiece. Additionally, the plate-shaped workpiece can contractionally deform toward the first positioning opening upon executing the hot press forming of the heated plate-shaped workpiece.
