Abstract

PURPOSE:To prevent damage of a punch and continous manufacture of a defective article, by detecting an excessive movement of fingers for pinching and holding a work molded by the first die, generating an electric signal, raising an alarm, or stopping a ram. CONSTITUTION:The first punch 1 pushes a work W into the first die 22 and primary molding is performed, and after that,while a ram goes backward, a chucking device 3 pinches and holds the work W, and shifts it to the front of the second die 22'. In case when a pair of fingers 54, 55 of this chucking device 3 have not pinched and held the work W due to some fault, a detecting device 4 provided on a stretch arm 60 formed on the base end of an arm 51 of the finger 55 is operated by excessive rocking of the fingers 54, 55. That is to say, the tip of a bolt 64 of the detecting device 4 press-contacts with a stepped part 70 of a head 42, conducts electrically to a frame 2, and an alarm or an emergency stop device of the ram is operated.
