Abstract
A press installation that has working stages with a press frame having press supports, a press bed, a headpiece, and turnbuckles which rigidly connect the press supports, the press bed, and the headpiece with one another. The press installation has a slide for forming that extends along a plurality of the working stages, a transfer device that transfers workpieces between the working stages, and driving devices that drive the slide and the transfer device. Connecting rods link the slide without pressure points and therefore directly in four linking points. The centers of the two linking points respectively of one side of the slide and of two turnbuckles situated opposite one another in the press frame are arranged on a common line which is aligned horizontally and vertically with respect to a press passage. The slide is an outer slide, while inner slides are provided in the working stages, these inner slides being vertically slidably disposed via guides. At least one overload safety device is respectively arranged between each of the inner slides and the outer slide, the overload safety device including a pressure space in a pressure cylinder and a piston. The pressure space is prestressed for operation of the press installation while admitting pressure via pressure lines to the piston and thereby to the inner slide in a vertically downward direction.
