<p>A drive arrangement for a high speed mechanical press, especially a high speed cutting press, wherein the press drive includes two eccentric shafts connected by connecting rods with a slide. Mass balancing weights are provided for enabling a complete dynamic mass balancing, with the weights being articulated by additional rods and being moved in a direction opposite to the slide. The drive further includes at least three pairs of toggle or knee joint link arrangements, with the first arrangement being nearly horizontally disposed, the second arrangement being nearly vertically disposed, and the third arrangement being nearly vertically disposed and connected on the one hand with the slide and, on the other hand, with the mass balancing weights, with the pairs being arranged symmetrically with respect to the eccentric shafts.</p> |
