Abstract: In a working method using a device for operating presses including 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: The invention relates to an articulated arm transport device which is especially provided for the automation of large component transfer presses. Said articulated arm transport device is characterized by a kinematics and design that do not require any additional clearance between the press rams and pillars and that permit an introduction or extraction of workpieces even with a small clearance between the upper and lower tool. The articulated arm transport device is mounted above the workpiece transport plane on the press stands. The articulated arm part linked with the cross-member is shorter than the articulated arm part and makes a pivoting movement substantially above the common pivot. A lifting and/or pivoting movement can be carried out by means of controlled lift drives that are functionally linked with transmission means.

Abstract: The invention relates to a device for transporting work pieces through pressing systems, in particular a double hinged arm feeder for step presses or press working lines. Said transport device is configured in such a manner that the work pieces are transported at high speed with a large system rigidity. The hinged arm is pivotably mounted on a slit which supports the pivot drive and which is guided on a rail whereon at least one stationary drive is located enabling the slits to move in a horizontal manner in relation to the slits and the whole unit can be moved in a vertical manner over at least one stationary lift drive. Due to said configuration, the hinged arm or the two hinged arm parts only have a small looped length.
