description The utility model relates to a transmission gear of a press machine. The transmission gear comprises a gear wheel, a first connecting rod, a rocker, a crankshaft, a key, second connecting rods, upper toggle rods, lower toggle rods, ball-headed screws and slider bodies. The gear wheel is fixedly connected with the first connecting rod and the rocker by hinge pins, the rocker is fixedly connected with the crankshaft by the key, the crankshaft is fixedly connected with the second connecting rods, the upper toggle rods are fixedly connected onto a machine body, the second connecting rods are fixedly connected with the upper toggle rods, the lower toggle rods are fixedly connected with the ball-headed screws, and the ball-headed screws are fixedly connected onto the slider bodies. The transmission gear has the advantages that sliders can stop at approximately 50-degree angles at lower dead points owing to unique running curves of multi-point toggle rod mechanisms, accordingly, the metal forming time can be prolonged to the greatest extent, and the transmission gear is favorable for plastic deformation of metal.
