ABSTRACT:
A crank type, C-frame pressing machine in which a robot for loading a workpiece and unloading a fabricated product is built-in within a space enclosed by the frame behind a fabricating station, with a pair of chucks on a feed bar extending across the front of the machine. The robot comprises a lift cam and a feed cam. Swing arms are provided each of which abuts the periphery of each of the cams, which arms are adapted to be actuated in conformity with the cam profiles. An actuation system is operatively connected to the swing arms and serves to transmit the actuation of swing arms to the feed bar. The actuation system includes a lift arm operatively engaging the swing arm for the lift cam and a drive arm operatively engaging the swing arm for the feed cam, the lift arm and the drive arm being constructed so that both are coupled to the feed bar, the former being movable vertically and the latter being movable vertically and laterally, to thereby transmit the vertical and lateral movements to the feed bar.
