SLIDE DRIVING DEVICE OF PRESS MACHINE AND PRESS MACHINE USING THE SAME

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 【課題】コンパクトで、かつ、プレス荷重と直交する横方向荷重を低減するスライド駆動装置を提供する。【解決手段】スライド２の運動方向と直交する方向の第１の軸心３ａを有する円板状の部材３と、その円板状の部材に一端が、前記第１の軸心と平行な第２の軸心４ａを回動軸として枢支されると共に、他端が駆動軸に回動自在に連結されるコンロッド４と、前記円板状の部材に一端が、前記第１の軸心と平行な第３の軸心５ａを回動軸として枢支されると共に、他端をプレス機械のフレーム１２に回動自在に連結されるレバー５とを備えており、前記コンロッドおよびレバーのスライドの運動方向に対するそれぞれの傾きが、スライドの下死点付近で、スライドの運動方向に対してほぼ対称にされている、プレス機械のスライド駆動装置１。【選択図】図１
