Patent number: 8555691Abstract: A metal plate material hot molding apparatus is provided for press molding a heated metal plate material. The apparatus may include supply piping for a cooling medium in a mold, and ejection holes penetrating from a molding surface of the mold to the supply piping. The exemplary apparatus may also include discharge piping for the cooling medium situated in the mold, and discharge holes penetrating from the molding surface of the mold to the discharge piping, and cooling piping. Molding procedure can be performed while the cooling medium is ejected from the ejection holes to a gap between the metal plate material and the mold.Type: GrantFiled: May 24, 2011Date of Patent: October 15, 2013Assignee: Nippon Steel & Sumitomo Metal CorporationInventors: Yasushi Kurisu, Yoshiaki Shia, Kazuto Yamamura, Yuuichi Ishimori, Hiroyuki Mitake, Tetsuo Shima, Hiroshi Fukuchi, Norimasa Yamasaki

Patent number: 8291740Abstract: A hot forming die according to an exemplary embodiment can be provided for a press forming apparatus which can press-forms a heated metal plate (e.g., a work material) and may cool the work material by ejecting a cooling medium onto the work material. The hot forming die can have a main supply path through which the cooling medium passes, a plurality of branch supply paths branching off the main supply path, injection ports for ejecting the cooling medium to the outside of the die, and nozzle members fixed on the ejection port side of the branch supply paths to restrict the passage amount of the cooling medium by using passage holes for allowing the cooling medium to pass there through. In a hot press forming method according to an exemplary embodiment, the cooling medium in the die can be held on standby after being pressurized to a degree at which the cooling medium is not ejected.Type: GrantFiled: March 1, 2007Date of Patent: October 23, 2012Assignee: Nippon Steel CorporationInventors: Yuuichi Ishimori, Tetsuo Shima
