    43816576, May 3, 1983
  • Filed:
    May 19, 1980
  • Appl. No.:
    6/151497
  • Inventors:
    C. Howard Hamilton - Thousand Oaks CA
    Paul R. Puhaczewski - Torrance CA
  • Assignee:
    Rockwell International Corporation - El Segundo CA
  • International Classification:
    B21D 2604
  • US Classification:
    72 60
  • Abstract:
    A method is disclosed for removing a part from a die, the part having been produced by clamping a preform between first and second dies and forming at least a portion of the preform into a cavity of the first die. The method comprises the steps of drawing a vacuum from between at least a portion of the formed preform and the second die and separating the second die from the first die such that the part is withdrawn from the cavity of the first die. In a preferred embodiment, wherein the part is clamped abouts its periphery, the method involves the additional steps of providing a channel about at least a portion of the second die aligned with and in communication with the periphery of the preform, and providing sealing members to seal off the channel. The vacuum is then drawn from the channel.
