Transmission device of press

The invention relates to a transmission device of a press. The transmission device comprises a gear wheel, a connecting rod I, a rocker, a crankshaft, a key, a connecting rod II, upper toggle rods, lower toggle rods, ball screws and a slider body, wherein the gear wheel is connected with the connecting rod I and the rocker through hinge pins; the rocker is fixedly connected with the crankshaft through the key; the crankshaft is fixedly connected with the connecting rod II; the upper toggle rods are fixedly connected onto a press body and fixedly connected with the connecting rod II; the lower toggle rods are fixedly connected with the ball screws; the ball screws are fixedly connected onto the slider body. A slider can stay at about 50 degrees at a lower dead point through a unique operation curve of a multi-point toggle rod mechanism, the metal molding time is increased to the greatest extent, and plastic deformation of metal is better facilitated. 本发明涉及种压力机传动装置，包括大齿轮、连杆、摇杆、曲轴、键、连杆、上肘杆、下肘杆、球头螺杆和滑块体，所述大齿轮分别与所
