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. The cam plate has a cam slot with first and second orthogonal portions lateral to the crank arm axis, and a third arcuate portion interconnecting the first and second portions at the radius of the crank arm. A cam follower is mounted on the crank arm and disposed in the slot, such that rotation of the drive shaft rotates the crank arm and propels the cam follower along the first, third and second portions of the slot and sequence, with the third slot portion providing a dwell at the cam plate and finger bar during motion of the cam follower therethrough.
