Abstract
A mechanical press for fine blanking, forming and/or stamping of work pieces has a machine frame provided with a head piece and an O-shaped frame, the head piece receiving in a fixed arrangement a fine blanking or forming head having an upper tool part, a ram provided in the O-shaped frame having a table top for fixing a lower tool part, the ram being actuable along a vertical stroke axis, and a toggle mechanism with a first and second side that is positioned below the ram. The toggle mechanism includes a connecting rod having a substantially equilateral triangle shape with articulation points pivotally attached to arms that pivot about a fixed bearing on the press machine and the ram, respectively, as well as around the connecting rod. Another portion of the connecting rod is attached to synchronous motors through a gear and shaft arrangement at another fixed bearing on the machine press. A computer controller adjusts the motors to equal path-time characteristics.
