Laser bending method and apparatus for bending a work piece in normal and reverse directions |
摘要 |
A work piece can be bent in opposite directions by irradiating a laser beam onto one side of the work piece. A tension anneal is applied to a metal plate. The metal plate is bent by irradiating a defocused laser beam onto a front surface of the tension-annealed metal plate so that the metal plate is bent in a state in which the front surface of the metal plate is convex at a position where the laser beam is scanned.
