Abstract

Proposed is a transfer system for presses, having at least two fastening units arranged opposite one another, wherein each of the fastening units in each case has a first fastening region. The transfer system further has a press transfer unit, consisting of two movement arms arranged opposite one another, as well as a crossbar connected thereto for receiving and for transporting, i.e. including setting down, a workpiece. Each of the movement arms has a first drive unit connected to the first fastening region, a first lever arm, a second drive unit, and a second lever arm. The first lever arm is connected at a first end thereof or between the first and a second end to the first drive unit, and at the second end thereof to the second drive unit. The second lever arm is rotatably connected at a first end thereof to the second drive unit, and is movably connected with a second end thereof to the crossbar. In addition, at least one energy-storing element is provided for each movement arm, which energy-storing element is formed and arranged in such a way that its force or a force component thereof points in the acceleration direction of the crossbar with or without.
