Title:
METHOD AND DEVICE FOR BENDING METALLIC PLATE BY LASER BEAM
Document Type and Number:
Japanese Patent JP2618123
Kind Code:
B2
Abstract:
PURPOSE: To provide the method and the device for bending a metallic plate by a laser beam, by which bending of 90° can always be executed irrespective of length of bending part, and also, bending of high quality is obtd. without suffering damage at an end part by heat, and moreover, a fixed bending angle can always be obtained.
CONSTITUTION: In the working method for bending where a laser light 11 scans one line on the surface of a metallic plate 12 plural times, this device is constituted so that the laser light 11 irradiates the surface of the metallic plate 12 from the oblique direction.
