GUIDING AND TRANSFER DEVICE FOR AT LEAST TWO WELDING STEEL SHEET BLANKS

摘要

The subject of the present invention is a device for guiding and transporting at least two sheet-metal panels to be welded edge to edge. …The device comprises, on the one hand, for each sheet-metal panel, means (14a, 15a) for supporting the sheet-metal panel in a horizontal reference plane, these means being horizontally movable in the direction of a laser beam, and means (14c, 15c) for vertically pressing the sheet-metal panel against the horizontally-movable support means, in synchronism with the said support means for the movement, by adhesion of the sheet-metal panels and, on the other hand, means for keeping in reference, in a vertical plane, the edge to be welded of one of the sheet-metal panels along the axis of the laser beam, and means for applying lateral pressure on the edges to be welded of the two sheet-metal panels. …The invention applies to installations for the laser-beam welding of sheet-metal panels of various geometrical shapes and/or of various thicknesses, for example for the automobile industry. ……
