PLATE MATERIAL MANIPULATOR FOR BENDING PRESS AND PLATE MATERIAL GRASPING DEVICE FOR MANIPULATOR

摘要

PURPOSE:To easily bend all sides of a pate material without changing a grasping way by providing a plate material grasping device freely rotatably on a supporting arm round the center of a specified axis. CONSTITUTION:Since the supporting arm 18 rotates round the center of an axis E, it can position the plate material W grasped by plate material grasping pads 26, 28 at an arbitrary angle to the bending surface of a bending press 1. Further, when the supporting arm 18 rotates 180 degrees round the center of an axis D, the plate material can be inverted to make a backward bending like W. Furthermore, when the plate material grasping pads 26, 28 are rotated round the center of an axis G, the four sides of the plate material can be bent in sequence without changing the position for grasping the plate material W.
