Document Type and Number:
Japanese Patent JP7324642
Kind Code:
B2
Abstract:
To provide a back gauge device of a press brake which prevents deterioration in processing efficiency.SOLUTION: A back gauge device (51A) of a press brake (91) includes: first and second back gauge units (2L and 2R) that are arranged so as to be separated in a horizontal direction and are movable; first and second abutting parts (27L and 27R) that are mounted on the first and second back gauge units (2L and 2R) and are rotatable between a horizontal position and a standing position; a first driving part (31L) for rotating the first abutting part (27L) between the horizontal position and the standing position; a first sensor (26L) for detecting the movement of the first driving part and outputting first movement information (J26L); a first control part (30L) for controlling the first driving part (31L); a second driving part (31R) for rotating the second abutting part (27R) between the horizontal position and the standing position; a second sensor (26R) for detecting the movement of the second driving part and outputting second movement information (J26R); and a second control part (30R) for controlling the second driving part (31R). The first control part (30L) controls rotation of the first abutting part (27L) based on the first and second movement information (J26L and J26R).SELECTED DRAWING: Figure 7
