Face-pushing tool of laser processing machine and face-pushing method thereof

摘要

In the present invention, the burr-like protrusions generated at the lower end edge portion along the thermal cut portion of the plate material by the thermal cutting process by the laser processing machine are efficiently utilized by utilizing the plate material feeding mechanism mounted on the same laser processing machine A surface pressing tool which can be removed well, a laser processing machine provided with the same, and a face pressing method in which the face pressing process is performed using the same. The face pressing tool (20) includes upper and lower ball holding members (42, 52) arranged to face each other, and ball holding members (42, 52) rotatably supported by the ball holding members And upper and lower balls (43, 53) protruding to oppose each other on the opposing surface of the upper case (3). The plate material (W) is fed by the plate material feeding mechanism along the thermal cutting section (A) in a state where the thermal cutting section (A) of the plate material (W) is sandwiched between the upper and lower balls (43, 53) , And the lower end edge portion along the heat-cut processed portion (A) of the plate material (W) is pressed upward by the lower ball (53).
