Adjustable stroke connection

摘要

An adjustment stroke connection for a mechanical press with an eccentric bushing is disposed within a press connection member with a second eccentric member disposed within the eccentric bushing. A rotatable crankshaft is connected to the second eccentric member. A mechanism is included for connecting the eccentric bushing with the press connection member to prevent rotation therebetween and permitting rotation of the second eccentric member with the eccentric bushing whereby rotation of the crankshaft, when the mechanism is activated, causes a press stroke adjustment.
