Abstract
The invention relates to a process and a device for the stretch-forming of semi-finished products, in particular metal sheet, whereby the metal sheet is clamped along its sides, pressure-loaded on its front side by an extrusion dye and subjected to heating by a laser beam on its rear side. The extrusion die performs a translation and/or rotational movement along and/or at least about another axis in addition to the stroke movement during the pressure impact on the sheet metal
