Abstract: A die transfer system for transferring workpieces between successive die stations in a stamping press includes elongated finger bars having spaced fingers for engaging workpieces at successive die stations, a first drive module for reciprocating the finger bar laterally into and out of engagement with the workpieces at the die stations, and a second or transfer drive module for reciprocating the finger bar longitudinally for transferring workpieces between the successive die stations. The transfer drive module includes a pair of laterally spaced transfer drive mechanisms respectively positioned adjacent to the ends of the finger bars, and a bridge that extends between the transfer drive mechanisms. A pair of carriages are mounted on the bridge and coupled by lead screws to respective stepper motors for adjusting position of each carriage laterally of the bridge independently of each other. Each carriage is coupled to an associated finger bar by a quick-disconnect coupling arrangement.

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 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.
