  • Patent number: 5572898
    Abstract: A die transfer system for transferring workpieces through successive dies stations in a stamping press includes an elongated finger bar having spaced fingers for engaging workpieces at successive die stations. A drive module for reciprocating the finger bar laterally into and out of engagement with the workpieces at the die stations, and for lifting the workpieces above the level of the die stations for longitudinal transfer between die stations. The drive module has a crank arm coupled to the drive shaft for rotating the crank arm about an axis parallel to the finger bar. A cam plate is coupled to the finger bar and mounted for movement lateral to the crank arm axis and the finger bar. A cam follower is mounted on the crank arm and disposed in a slot on the cam plate, such that rotation of the drive shaft rotates the crank arm and propels the cam follower along the slot to move the cam plate and finger bar horizontally and vertically in sequence.
