Abstract
The invention relates to a punch press with a crank or eccentric drive, including a crank or eccentric shaft (1a, 1b) and active connecting rods (9a, 9b) for generating the stroke movement of the press ram (13). Furthermore, the punch press includes balancing weights (2a, 2b) for balancing the vertical and horizontal mass forces and is designed in such a way that the horizontal drive movements required for the horizontal mass balancing are tapped directly at the crank or eccentric shaft (1a, 1b), preferably laterally at the crank or eccentric shaft (1a, 1b).
Claims20
A punch press with a crank or eccentric drive, comprising a crank or eccentric shaft and active connecting rods for generating stroke movement of a press ram, and with balancing weights for balancing vertical and horizontal mass forces, wherein the punch press is adapted in such a way that horizontal drive movements required for horizontal mass balancing are tapped directly and laterally at the crankshaft or eccentric shaft, wherein the punch press is adapted in such a way that drive movements required for the vertical mass forces balancing are tapped directly at the crankshaft or eccentric shaft, wherein the press is adapted in such a way that each of the balancing weights serves to balance both horizontal and vertical mass forces, wherein the punch press is adapted in such a way that the active connecting rods extend from the crankshaft or eccentric shaft in a direction of the press ram, wherein the ends of the active connecting rods facing away from the crankshaft or eccentric shaft are each articulated to one end of a single-sided lever, the other end of which is mounted in an articulated manner on the housing of the punch press, either directly or via further coupling members, and wherein a thrust shackle, which is connected to the press ram, is articulated to each of the single-sided levers in a region between their two ends.
