Abstract: In a working method using a device for operating presses comprising a ram and a die, such as forming presses or cutting presses, for example multiple-die presses for large workpieces, transfer presses, multi-ram transfer presses, such forming presses or cutting presses also being arranged in press lines, smaller ram strokes result in optimized freedom of motion of the press, in place of the existing large freedom of motion, the acceleration and speed of the ram are at most maintained, or reduced, while parts output is increased, and smaller paths are made possible due to dynamic ram stroke and transfer movements. To this end, the work process of the ram stroke of presses is controlled according to a curve that follows the function f(x)=a(0)/2+a(1)*cos(1*x)+ . . . +.

Abstract: A transporting apparatus, in particular a 3-way transfer means, for transfer presses, in the case of which, for horizontal movement, linear drives are attached and actuated such that, along with a compact construction, the linear drives allow the gripper rails to be changed straightforwardly during tool-changing operations.

Abstract: A preshaping method for massive forming processes is proposed in which a fixed blank is deformed by at least one roll moving continuously forward along a predetermined contour.

Abstract: A forming press for external high-pressure forming is proposed, in which the fluid box (10) is arranged stationarily. Working cylinders (6) are integrated in the ram (2) so as to achieve a compact design, and the sheetholding and closing force is applied by short-stroke cylinders (7).

Abstract: The invention relates to a process for controlling casting parameters and in particular to the control of the metering of the molten metal in a casting chamber of a vacuum die-casting machine. Measurement devices connected to a computer determine the volume and condition of the molten material. An evacuation device and a vacuum valve are controlled in the form of a control circuit.
