DEBURRING DEVICE

PURPOSE:To set the deburring quantity automatically and dispense with the adjustment of pressing force despite the material change of plates by setting the pressing force of a deburring knife on the basis of the information of a storage device, and controlling a pressing driving means so as to obtain the set pressing force. CONSTITUTION:The cutting edge 3 of a knife 1 is brought into contact with or separated from strip material 4 through a piston by supplying/discharging air to/from a cylinder 10 so as to remove a burr 5. In this case, the air supply port 11 and air supply-discharge port 10b of the cylinder 10 are connected to air supply source respectively through a solenoid change-over valve 21 and a pressure reducing valve 23 so as to form a pressing driving means. An automatic pressure regulator 26 for regulating air pressure is interposed between the solenoid change-over valve 21 and the pressure reducing valve 23. The automatic pressure regulator 26 is connected to a control device 28, and the control device 28 is connected to a storage device 29. The storage device 29 is made to store the material quality of the strip material 4 and the depth-of-cut quantity of the knife 1, and the control device 28 controls the automatic pressure regulator 26 on the basis of the stored data.
