ABSTRACT:
A die for drawing molded sheet metal parts has a bottom part of the die and a top part of the die. These parts are movably guided toward each other. One of these parts has a draw ring. The other part of the die has a sheet metal holder received on a plurality of hydraulically operating cylinders. There is a draw punch, which is enclosed by the sheet metal holder and is supported on at least one hydraulically operating cylinder. The punch is communicatively connected with at least one of the operating cylinders serving for the support of the sheet metal holder. The punch is acted upon by a hydraulic fluid displaced from this operating cylinder during the drawing process. Thus, the draw punch will move in the direction opposite to the movement of the sheet metal holder.
