  • SYSTEMS AND METHODS FOR IMPROVING BACKWARD FLOW FORMING OF SHAFTS
    Publication number: 20220048089
    Abstract: An apparatus for backward flow forming a material may comprise a mandrel having a headstock at a proximate end of the mandrel, the mandrel configured to rotate about an axis, a plurality of rollers disposed radially outward of the mandrel configured to exert force on the material to form a work piece at a plastic deformation zone, wherein the work piece flows from the plastic deformation zone between the plurality of rollers and the mandrel toward a distal end of the mandrel, and a catcher, coaxial to the mandrel, and removably coupled to the work piece at a traveling end of the work piece.
    Type: Application
    Filed: October 28, 2021
    Publication date: February 17, 2022
    Applicant: Raytheon Technologies Corporation
    Inventors: Agnieszka WUSATOWSKA-SARNEK, John PALITSCH
