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. In this way, the transfer drive mechanism may be readily disconnected from the lateral drive mechanisms for replacement of the latter, and may be readily readjusted for and connected to new lateral drive mechanisms of differing configuration.
