Abstract

PURPOSE: To prevent the production of defective articles, by providing detectors in positions where a piston rod and a movable member are located when a bend tap starts cutting a blank under proper conditions and by identifying it with abnormality that the outputs of both the detectors are not simultaneously obtained.
CONSTITUTION: A movable member 10 is pushed on a piston rod 5 by a spring 9. A pusher rod 11 provided on the movable member 10 is reciprocated by the rotation of an eccentric cam 8. The positions of the piston rod 5 and the movable member 10 at the time of starting of cutting of a blank 19 by a bend tap 21 are found out by detectors 25, 23. It is identified with abnormality that the outputs of the detectors 25, 23 are not simultaneously obtained during the tapping of the blank 19. At that time, the tapping machine is stopped. Therefore, the tapping work is prevented from being continued under abnormality. The production of defective articles is thus avoided.
