損確認装置。In a press machine that performs hole punching by punching a workpiece placed on the top surface of a punch die, a piezoelectric transducer that outputs the reaction force applied to the punch as an electric signal is installed at the rear end of the punch. The piezoelectric transducer is provided on the side and electrically connected to a controller that outputs an abnormal signal, and when the punch is lowered to a lower limit, the piezoelectric transducer does not output a signal, so that the controller outputs an abnormal signal. A breakage confirmation device for a hole punch.
