Patent number: 10843291Abstract: A component is formed by welding a plurality of sheets of metal to form a blank with a number of weld nuggets, placing the blank between a die section and a lid section, heating the die section to heat the blank, and introducing a pressurized gas between the lid section and the die section to press the blank into a mold in the die section to form a component. The number of weld nuggets has a desired thickness ratio between about 1.1 to about 1.25 such that the plurality of sheets of metal and the component formed have a number of characteristics that are substantially the same.Type: GrantFiled: November 12, 2009Date of Patent: November 24, 2020Assignee: The Boeing CompanyInventors: Daniel G. Sanders, Luis R. Leon, Paul D. Edwards, Gregory L. Ramsey, Gary W. Coleman

Patent number: 8402805Abstract: A method and apparatus are used to form a corrugated web having a cross sectional shape with at least one characteristic that varies substantially continuously along the substantially the entire length of the web. The apparatus includes multiple sets of dies which progressively form corrugations in a moving sheet. At least one characteristic of the web's cross sectional shape is varied along the entire length of the web by displacing the dies as the sheet moves through the die sets.Type: GrantFiled: September 25, 2008Date of Patent: March 26, 2013Assignee: The Boeing CompanyInventors: Luis R. Leon, Joseph R. Olivadoti, Garry A. Booker

Patent number: 6834525Abstract: An apparatus and method for forming corrugated contours in a sheet are provided. The apparatus includes at least three pairs of elongate dies that extend in a longitudinal direction. Each pair of dies is generally parallel and defines a nip therebetween so that the sheet can be moved successively through the nips. At least one actuator is configured to actuate each pair of dies in successively opposed directions generally perpendicular to a direction of motion of the sheet to thereby form the contours in the sheet. Further, each pair of dies is adjustable in a transverse direction generally parallel to the direction of motion of the sheet so that an offset distance between each successive pair of dies can be adjusted.Type: GrantFiled: November 18, 2002Date of Patent: December 28, 2004Assignee: The Boeing CompanyInventors: Luis R. Leon, Joseph R. Olivadoti
