ABSTRACT:
A workpiece ejecting mechanism for a forging apparatus includes a rod passage formed in a machine bed, and a workpiece pushing rod and a driving rod which are received slidably in the rod passage. An air passage is formed in the machine bed and is communicated fluidly with the rod passage so as to fill the rod passage with compressed air via the air passage, thereby biasing the pushing rod to move away from the driving rod until a front shoulder of the pushing rod contacts a front blocking unit, and thereby biasing the driving rod to move away from the pushing rod until a rear shoulder of the driving rod contacts a rear blocking unit.
