摘要

Process for deep drawing sheet metal into molded parts comprises deforming in the region of the local shape contours using an active medium of a fluid stream directed against the shape contours with a pressure higher than the stream pressure. An Independent claim is also included for a device for deep drawing sheet metal into molded parts comprising a stamp (1) having the shape contour of the molded part base; a lower tool (5) with inlet and outlet (6, 7) for the fluid medium; and a holder (8). Jet nozzles (13, 14) for producing fluid streams are arranged in the lower tool.
