Abstract

PURPOSE:To remarkably reduce the number of defective workings due to the breakdown of a punch by fitting a laser type displacement sensor to the position facing for the punch of the inside of a press device and executing the operation control of the press device by the output signal thereof. CONSTITUTION:The forming of a work 7 is executed by providing a punch 2 at the lower part of the upper die 5 of a press device 1 and placing the work 7 at the upper part of a lower die 6. At this time, a jig 8 is provided towards the upper part slightly of the lower die 6 on the back part of the upper and lower dies 5, 6, a laser type displacement sensor 3 is fixed thereto and driven by its advance and retreat towards the punch 2 by an air cylinder 10. At the time when the punch 2 is lowered together with the upper die 5 with this composition, a laser beam is projected on the tip part 9 of the punch 2 and the breakdown or wear state of the punch 2 is calculated by an arithmetic circuit 11 from the output signal of the sensor 3. A command is given to a control device 4 according to this calculation result and the operation of the press device 1 thereafter is stopped.
