Abstract

The company Schnupp GmbH + Co. Hydraulik KG, Bogen, has developed a new type of press for sheet metal hydroforming. The advantages of this machine are derived from its new cinematic characteristics, with spacers inserted between the machine frame and press ram during the forming process. These spacers transmit the high forces to the press frame via positive engagement. The nominal press force is generated by 100 short-stroke cylinder which are located underneath the table plate. These short-stroke cylinders, which can be switched on or off individually, are divided into six independent control circuits. Thus it is possible to influence the blankholder force locally during the forming process. A system of this kind has already found its successful application at AUDI AG, Ingolstadt, for the sheet metal hydroforming.
