US Patent:

53598741, Nov 1, 1994

Filed:

Nov 12, 1991

Appl. No.:

7/791103

Inventors:

Richard D. Buckley - Watkinsville GA
Thomas L. Linsenbardt - Lohman MO
Harold Younger - Halifax VA
Darrell D. Harris - Fulton MO
Dennis J. Struemph - Mea MO

Assignee:

ABB Power T & D Company, Inc. - Blue Bell PA

International Classification:

B21C 2306

US Classification:

72256

Abstract:

Twin metal billets are fed to dual circumferential grooves formed in a rotating wheel. The billets are advanced first to a wedge-shaped gap which deforms the billets and are then advanced to a die. The die has a die opening with a circumferentially discontinuous, annular cross-section. The metal from each billet merges in the die opening and exits therefrom in the form of a slit tube. The tube is then opened and flattened to form a flat strip by advancing the slit tube over a forming member having a progressively increasing width.

Abstract:

In a transformer housing assembly including a tank and a base supporting the tank, the tank being arranged to contain a body of oil and a transformer the tank and base are secured together, subsequent to individual fabrication thereof, by a plurality of fastening devices. Each fastening device includes an attachment member which is permanently fastened to an upwardly projecting recess formed in the tank bottom, the attachment member being dimensioned to not extend below the portions of the tank bottom surrounding the recess, and the attachment being provided with an internally threaded lined bore. Each fastening device further includes a clamping member extending across the associated recess in the tank bottom and a bolt which passes through an opening in the clamping member and engages in the threaded line bore in order to cause the clamping member to clamp a flange provided at the upper end of the base to the tank bottom. In order to prevent the insertion of thin bodies between the tank and the base, a T-shaped baffle is provided. The baffle includes a leg which is clamped between the tank bottom and the base flange and a vertical cross piece which bears against front panels of the tank and base.
