| 20090050676 | TOOL AND METHOD FOR ASSEMBLING METAL PARTS BY IMPACTING WITH THE AID OF MAGNETIC FORCE USING TWO ELECTROMAGNETIC COILS MOVABLE WITH RESPECT TO EACH OTHER - A tool for assembling a part made of a ferromagnetic material with a part made of a paramagnetic material. The tool includes a first tool part including a first abutment and a first electromagnetic coil. The tool also includes a second part including a second abutment, wherein the second part is mechanically assembled with the first part such that the first and second abutments are selectively attracted or repelled with respect to each other. The first electromagnetic coil is used for generating an electromagnetic flux that enables the paramagnetic part to be pushed towards the second abutment and/or the ferromagnetic part to be attracted thereto when the first and/or second part is placed between the first and second abutments. | 02-26-2009 |
| 20100140328 | METHOD AND APPARATUS FOR MAGNETIC IMPULSE WELDING OF SHEETS - A first sheet, includes, but is not limited to at least one attachment region inclined at an angle to a sheet plane. The first sheet is arranged on a second sheet so that the attachment region of the first sheet is spaced at a distance from the second sheet. A magnetic field pulse is applied so as to cause a force on the attachment region in directions generally perpendicular to the first sheet plane and the second sheet plane so that the attachment region of the first sheet is driven against the second sheet with sufficient force to produce a cold-welded joint between the attachment region of the first sheet and the second sheet. | 06-10-2010 |
| 20110000953 | LOW-TEMPERATURE SPOT IMPACT WELDING DRIVEN WITHOUT CONTACT - A laser, aimed at a flyer plate tab, causes optical energy to be directed at the tab, specifically, at a top surface thereof. Energy impacting the tab accelerates the tab out of an initial bent position, straightening it into an impact with a target sheet. The impact occurs in excess of 100 m/s, resulting in a metallurgical bond between the tab and the target sheet. The laser preferably strikes the top surface in a normal direction, based upon an initial angularity of the tab relative to the target. The laser emission, preferably in the range of 1 to 100 Joules delivered in a microsecond, may be augmented by an ablative layer on the top surface or a transparent covering on the top surface that reacts against the expanding gas from ablative activity on the top surface. The weld is formed without physical contact between the welding device and the tab. | 01-06-2011 |
| 20110095072 | PRESS METHOD AND PRESS APPARATUS - A press apparatus includes a mounting table and a pressing member. A workpiece formed of a plurality of laminated core sheets is placed on the mounting table, and the pressing member is used for pressing the workpiece on the mounting table from above. The mounting table is supported by a base member so as to be loosely movable in a horizontal plane. When the pressing member is lowered, a positioning member determines the position of the workpiece such that the core sheets of the workpiece are aligned along a single vertical axis. | 04-28-2011 |
