  • Patent number: 9790564
    Abstract: A heat treatment apparatus for hot stamping includes a frame, and heating units provided to be vertically movable at both upper and lower sides of the frame and configured to heat a cold formed steel plate by electrifying the steel plate. Cooling units are provided to be vertically movable at centers of the upper and lower sides of the frame and are configured to cool the heated steel plate while pressurizing the steel plate from upper and lower sides.
    Type: Grant
    Filed: October 23, 2014
    Date of Patent: October 17, 2017
    Assignee: Hyundai Motor Company
    Inventors: Jae Ryeon Hwang, Byung Hun Kim, Jong Ho Maeng, Jang Choon Park, Heong Joo Park
  • Patent number: 9731337
    Abstract: A part correcting device for an automobile part may include a body in which the part is disposed, a hydraulic apparatus which presses and fixes one side of the part disposed in the body, a warpage correcting apparatus which corrects a warpage of the part by rotating the other side of the part left or right while fixing the other side of the part disposed in the body, and a deformation correcting apparatus which corrects an angle of the part by pressing flanges formed on both sides of the part downwardly while fixing the flanges.
    Type: Grant

  • Patent number: 8449647
    Abstract: A method of inoculating magnesium (Mg) on compacted graphite iron (CGI) comprises: providing a partition having a predetermined height on the bottom of a ladle so as to divide the interior of the ladle into a first space and a second space; laminating an Mg inoculant and a cover in order in the second space; and tapping liquid CGI cast iron onto the first space, whereby the Mg inoculant becomes in contact with the liquid CGI iron after the liquid CGI tapped onto the first space goes over the partition toward the second space and after the cover is melted by the liquid CGI. According to the method, the deviation of density of Mg is minimized, and a secondary inoculating process can thus be omitted.
