Title:
PRESS BRAKE AND BENDING PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2019010666
Kind Code:
A
Abstract:
To provide a press brake capable of accurately detecting a bending angle.SOLUTION: A press brake 1 in an embodiment comprises: a RAM 12; a stationary table 11; a light source 21; a CCD camera 22; an analysis range setting part 32; and an angle calculation part 33. To the RAM 12, a punch 2 can be attached. Plural kinds of dies 3 different in shape can be attached to the stationary table 11. The light source 21 projects linear light to a workpiece W mounted on a die 3 which is attached to the stationary table 11. The CCD camera 22 images a light projected image 42 formed on a surface of the workpiece W by the light in bending processing. The analysis range setting part 32 sets an analysis range 41 from a picked up image 40 obtained by the CCD camera 22 based on the kind of the die 3 attached to the stationary table 11. The angle calculation part 33 determines a bending angle of the workpiece W based on the light projected image 42 in the analysis range 41.SELECTED DRAWING: Figure 2
