Abstract

PURPOSE: To control a series of operation of a press accurately by installing an eddy current type position detector that reacts to a powder formed part but difficult to react to metallic powder in a die table the feeder of which slides at specified timing.
CONSTITUTION: A work 8 formed by punches 3, 4 in a die 2 is placed on the punch and knocked out on a die table 1, and pushed by the front end 6a of a feeder 6 that advances from the side to feed metallic powder 5 into the die 2. When the work 7 moves onto a nonmetallic plate 7, an eddy current type position detector head 9a below it generates eddy current, and presence of the work 8 is confirmed. When this confirmation is not made, it is judged that the work 8 adheres to the upper punch or the material is not supplied, and the press is stopped automatically to prevent double punching and to eliminate damage to the die. When the feeder 6 moves to the right, a metallic plate 11 behind it passes the similar detector head 12a and returning of the feeder 6 to the fixed position is confirmed.
