Abstract

PURPOSE:To simplify a device by bending the tip of a retained work up or down with a movable frame which has a couple of upper and lower bending dies, by equipping the movable frame to a guide frame at the front part of a head so that the movable frame moves up and down freely. CONSTITUTION:On a head 2, a work 30 is placed and while its tip projects by prescribed length, a cylinder 4 is put in operation to move down a ram 3, retaining the work 30 between upper and lower dies 5 and 6. Then, a cylinder 18 is put in operation to move up a movable frame 8 in a guide frame 7, thus bending the work upright at right angle by a bending die 16 for bending-up. When it is moved down, it is bent down by a bending die 15.
