Filed:

Nov 18, 2002

Appl. No.:

10/298451

Inventors:

Luis R. Leon - Federal Way WA
Joseph R. Olivadoti - Gig Harbor WA

Assignee:

The Boeing Company - Chicago IL

International Classification:

B21D 1302

US Classification:

72385, 723796, 72383, 72416, 72446

Abstract:

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.

International Classification:

B23K 31/02

US Classification:

2281121, 228 21, 244117 R, 72 61

Abstract:

A superplastically formed structural assembly is provided, as is an associated preform and method for forming such an assembly. The assembly includes a skin member and a support member that are joined to define a space between the members and between the joints. The assembly can be produced by joining the members in a flat configuration, and then forming the resulting preform to a predetermined shape of the structural assembly. The support member defines at least one aperture in communication with the space between the members. Thus, the skin member can be formed by delivering a pressurized fluid through the support member to the skin member, e. g. , to superplastically form the skin member against a die that defines a contour surface corresponding in shape to the predetermined configuration of the assembly. The support member can extend in a substantially direct configuration between opposing portions of the skin member.

US Classification:

723796, 72385, 72226

Abstract:

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.

US Classification:

228114, 228155, 228 21, 2281121

Abstract:

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.
