ABSTRACT:
In a transfer feed press having a vertically movable slide, one or two longitudinally movable multi-segment transfer feed rails for moving workpieces through the press, a bolster movable transversely in and out of the press and vertically within the press, and vertically movable rail support stands on the bolster, a die-changing control system comprising the combination of at least two controllable motor-actuated means for connecting and disconnecting the transfer feed rail segments; means for generating electrical signals representing the press slide position, the rail position along the longitudinal, transverse and vertical axes, the bolster position along the transverse and vertical axes, and the position of the rail support stands on the bolster; and control means for actuating the controllable motor-actuated means for connecting and disconnecting the transfer feed rail segments in response to the electrical signals when the press slide is in a raised position high enough to permit safe removal of the bolster and die from the press, the rail position is centered over the bolster and the rail support stands carried by the bolster, the bolster is in its advanced vertical position within the press, and the rail support stands on the bolster are in their raised positions.
