ABSTRACT:
A method of producing similar deep-drawn parts for double-walled structural parts having uniformly spaced walls and edge welding. During every deep-drawing procedure, a respective planar outer plate, which is placed upon the lower part of the tool, as is a filler plate, as well as a preformed or preshaped inner plate, which is placed over the tool punch, are shaped in common, whereby the preformed inner plate and the outer plate receive their final form or shape, and the filler plate is deformed into a preshaped inner plate for a subsequent deep-drawing procedure. The tool for carrying out this method is characterized in that the smallest spacing between the tool punch and the lower part of the tool corresponds to the entire thickness of the two inner plates and one outer plate.
