Abstract

A hydro-elastic deep drawing system for use with a press, for the deep drawing of sheet metal workpieces, consists of a tool mounting plate (8) which is fastened to the press ram (2), and a punch (5) which is mounted on the press bedplate (6). As the press ram descends the sheet metal blank is gripped between the upper (4) and lower (12) holding down plates which are pressed together by rows of hydraulically actuated pins (13). When these pins reach the ends of their strokes they activate hydraulic cylinders (3) which are installed in the lower part of the press so that the tool is pushed upwards against the sheet metal blank to form a workpiece of the required shape.
