Abstract

PURPOSE:To prevent the breakdown of the blade of a die by attaching the pressure fluctuation detector of an inlet pipe to the inlet pipe connected to a punching die hole, an abnormality is detected by the detection signal of a detecting pipe and executing the stoppage of a work or an alarm. CONSTITUTION:A reverse injection nozzle 10 of a compressed air is arranged in an inlet pipe 5 and the fed compressed air is injected to the downstream direction from an injection port 13 via an annular air passage 12. A pitot tube 14 is connected at the upper stream than the nozzle 10 to detect the pressure fluctuation. When the state of a punching chip (b) being clogged in the punching die hole becomes, a contactless switch 15 is actuated by the position change of the float 14a of the pitot tube 14 and the punching action is stopped or an alarm is sent. The punching action is re-opened after removing the punching chip in case of a stoppage or an alarm. The breakdown of the blade of a die is thus prevented and the product of high accuracy can be obtd. stably over a long term.
