ABSTRACT:
The bending device with a cutting mechanism has a bending die corresponding to a desired bending shape, a bending arm that rotates on the bending die, and a clamping die on the bending arm that moves toward a longitudinal workpiece. Corresponding to rotation of the bending arm, the clamping die is rotated around the bending die in order to bend the workpiece. A cutter is provided on the bending arm. The cutter is in a pointed shape having the center of a leading end protruding, and moves toward a workpiece. The clamping die has a groove wherein the cutter can be slid therein. The cutter moves linearly toward a workpiece and cuts the workpiece.
