ABSTRACT:
A beam-type transfer mechanism for moving workpieces step by step along a row of stations through the dies of a press to progressively form a blank into a finished part. A pair of laterally spaced beams extend parallel to the row of stations, having opposed work holding fixtures cooperable to grip the workpiece. The beams are movable in operation laterally toward and away from each other, vertically up and down, and longitudinally, to simultaneously advance the workpieces one step at a time from station to station. The dies would ordinarily be removable and replaceable through the front of the press except for one of the beams which occupies and obstructing position throughout its entire operative movement. Means are provided to lift the beams sufficiently to enable the removal and replacement of the dies through the front of the press without obstruction.
