Abstract

This press machine comprises a crankshaft (16) rotatably supported on a frame (14) and a power transmission (30) for transmitting rotary motion of the crankshaft to a slide (20). The power transmission includes: a bell crank (70) supported on the frame so as to oscillate about an axis parallel to the rotation axis of the crankshaft; a connection member (72) for connecting the bell crank and the slide so that the slide can perform vertical motion with oscillation of the bell crank; a slider (38) disposed on the frame so as to move vertically; a connecting mechanism (36) connected with the crankshaft, the bell crank and the slider so that the bell crank can oscillate with rotation of the crankshaft; and a position adjusting mechanism (40) for adjusting the position of the slider vertically.
