PROBLEM TO BE SOLVED: To provide a compact slide driving device capable of reducing the lateral load orthogonal to the press load.SOLUTION: The slide driving device 1 of a press machine includes: a disk-like member 3 having a first axis 3a in a direction orthogonal to a direction of motion of a slide 2; a conrod 4 one end of which is connected to the disk-like member pivotally around a second axis 4a parallel to the first axis, as a rotation axis, and the other end of which is rotatably connected to a driving shaft; and a lever 5 one end of which is connected to the disk-like member pivotally around a third axis 5a parallel to the first axis, as a rotation axis, and the other end of which is rotatably connected to a frame 12 of the press machine. The respective inclinations of the conrod and the lever with respect to the direction of motion of the slide are substantially symmetrical to each other with respect to the direction of motion of the slide, in the vicinity of a bottom dead center of the slide.SELECTED DRAWING: Figure 1 |
