Deep-drawing/shaping of molded parts made of steel sheet, comprises cutting first planar blank under achievement of rough outline, bringing two passages into the blank, and remolding edge of the blank in two deep-drawing/shaping procedures
The method for deep-drawing or shaping of molded parts made of steel sheet, comprises cutting a first planar blank (4) under achievement of a rough outline (5), bringing two passages (6, 7) into the blank, over which it is definable on corresponding fixing elements in a forming tool made of aluminum, and remolding edge (15) of the blank (4) successively in two deep-drawing or shaping procedures. The blank receives a pre-form and a final-form in the first and second deep-drawing or embossing procedures respectively. The passages lie on places (10, 11) with smaller material extrusion.

The blank receives a pre-form and a final-form in the first and second deep-drawing or embossing procedures respectively. The passages lie on places (10, 11) with smaller material extrusion during the deep-drawing or shaping and are intended outside of the mold part within the area of sheet metal lobes. The edge of the remolded blank is cut between the first and the second deep-drawing or shaping procedures. An independent claim is included for a procedure for manufacturing a forming tool for deep-drawing or shaping of molded parts.
