US Classification:

219603, 219606
Abstract:

There is disclosed herein an apparatus for electromagnetic forming, joining or welding a workpiece, the apparatus including at least two multi-turn solenoid coils wound in a manner that cooperatively encircles the workpiece to be formed. The apparatus also includes an electrically insulative shell encasing each coil and an electromagnetic current source electrically connected to the coils that generates an electromagnetic field. A hinge mechanism connects the insulative shells and a locking mechanism secures the shells and coils around the workpiece during electromagnetic field generation. A conductive rod joins the solenoid coils and permits series current flow between the coils. The apparatus further includes a shaper that encircles the workpiece and which restricts movement of the workpiece during electromagnetic forming. The shaper concentrates the generated electromagnetic field on the workpiece.

US Patent:

7197970, Apr 3, 2007
Filed:

Jul 29, 2004
Appl. No.:

10/710712
Inventors:

Sergey Golovashchenko - Beverly Hills MI, US
Michael Blodgett - Holland OH, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

B26D 1/04
US Classification:

83167, 83694
Abstract:

An apparatus for trimming scrap from an aluminum sheet metal blank is provided. The apparatus includes a clamping base comprising a clamping base engagement surface positioned between a clamping base upper surface and a clamping base bottom surface. The clamping base engagement has a clamping base vertically orientated portion and a clamping base angled portion. A steady blade is mounted to the clamping base. The steady blade and the clamping base form a contiguous angled engagement surface. The steady blade engagement surface forms a steady blade trimming edge. An elastic scrap support and an upper clamping element are included. A moving blade includes a moving blade trimming edge formed by the intersection of the moving blade blade-side surface and the moving blade engagement surface. The moving blade engagement surface distributing strain on the aluminum blank as the moving blade trimming edge separates the scrap element from the aluminum blank.

US Patent:

7493787, Feb 24, 2009
Filed:

Dec 11, 2006
Appl. No.:

11/609053
Inventors:

Sergey Golovashchenko - Beverly Hills MI, US
Vyacheslav Mamutov - St. Petersburg, RU
Andrey Ilinich - Dearborn MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

B21D 26/12
B21D 22/12
US Classification:

72 63, 72 56, 294211
Abstract:

An electro-hydraulic forming tool is disclosed in which a membrane is retained between two volumes of liquid that are separated by a membrane. Electrodes are provided with a high voltage impulse to create a shockwave in one of the volumes of fluid that is transferred through the membrane to the other volume of fluid. The shockwave is transmitted to a blank that is formed into a one-sided die. The blank is formed against the forming surface of the die. Air evacuation means are provided to remove air from the upper surface of one or both volumes of liquid.
