  • Method for treating large cast iron dies, particularly for vehicle-sheet metal pressing
    Patent number: 4899024
    Abstract: A method for preparing large cast iron dies for use in pressing the sheet-metal components of vehicle bodies is described; this method results in improved pressing performance, such as extended life and, in particular, drastic reduction in rejects and stoppages due to seizure; its main characteristic consists of subjecting to induction hardening treatment those die regions most subject to operational wear.
    Type: Grant
    Filed: December 21, 1987
    Date of Patent: February 6, 1990
    Assignee: Fiat Auto S.p.A.
    Inventors: Luciano Puozzo, Maurizio Manzin
  • Method for processing large cast iron dies, particularly for vehicle sheet-metal pressing, and the apparatus for its implementation
    Patent number: 4851637
    Abstract: A method for processing large cast iron dies for use in pressing the sheet-metal components of vehicle bodies is described; this method results in improved pressing performance, such as extended life and, in particular, drastic reduction in rejects and downtimes due to seizure; its main characteristic consists of subjecting those die regions most subject to operational wear to localized heating by a laser beam which strikes normal to the surface so as to harden the treated regions without the risk of cracking; the treatment is implemented by a focusing head controlled by a robot having five capabilities of movement.
