Definitions

  • the invention relates to a cutting and forming press with a hydro-mechanical articulated lever drive, in which the drive cylinder for the ram is carried by a guide arranged in the stator between lateral guides, via a bridge construction connected to it by threaded spindles or other height-adjustable means, and which is adjustable within the area of the free space of the frame-shaped stand
  • German patent specification DE-C-29 25 416 introduced a toggle lever sheet metal cutting press, introduced as a differential travel press, with a pressure medium cylinder drive arranged between two toggle lever systems that bend with their knee joints towards the center of the press and are symmetrical about this, the piston of which presses the end of its piston rod at the center of the press joint attacks two links, which are articulated at the other end to the toggle lever systems, the connecting joint with the help of the press ram having a guide transverse to the direction of the piston rod, the criterion of which is the support of the pressure medium cylinder drive on the press ram, whereby according to a further claim the ram is designed as a frame.
