Abstract (en)
[origin: WO2020211931A1] The invention relates to a punching press with a crank drive or eccentric drive, comprising a crankshaft or eccentric shaft (1a, 1b) and an active connecting rod (9a, 9b) for producing a reciprocating motion of the ram (13). The punching press also comprises counterweights (2a, 2b) for compensating for the vertical and horizontal inertial forces and is designed such that the horizontal driving motions that are necessary for the horizontal mass balancing, are taken up directly on the crankshaft or eccentric shaft (1a, 1b), specifically preferably laterally on the crankshaft or eccentric shaft (1a, 1b).
