  • Drawing heavy walled parts
    Patent number: 4339939
    Abstract: The method of drawing uniformly heavy walled parts in a multiple plunger machine without any intermediate anneals and a machine for carrying out the method. The method comprises a number of press operations which convert a flat blank to a final desired drawn configuration, the relatively uniform wall thickness being maintained throughout the operation by the mouth configuration of each die and by means of supplemental sleeves that assist the punches in extending the drawn shells into the dies with no stretch to the metal or thinning of walls. Work hardening due to stretch or tensile load is minimized allowing more deformation without anneals.
    Type: Grant
    Filed: June 15, 1981
    Date of Patent: July 20, 1982
    Assignee: Textron, Inc.
    Inventors: Walter R. Book, Anthony M. Putetti
  • Toggle-actuated punch stripper
