Abstract

PURPOSE: To perform chamfering and straightening safely and accurately by subjecting sintered parts to chamfering of their bores by the same operation as that of straightening before or after the straightening position of a turntable at the time of straightening said parts with a straightening press feeding said parts automatically by using the turntable.
CONSTITUTION: When a turntable 1 rotates by a constant angle in comformity with the movement of a straightening press body, a sintered part A moves from S1 to S2 and the sintered part A after chamfering from S2 to S3. At this time, the upper ram 7 of the straightening press descends and the upper punch and upper punch and core rod 2 mounted to a supporting plate 4 lower to straighten the chamfered sintered part A. At the same time, the chamfering rod mounting plate 6 and chamfering core rod 5 mounted to the plate 4 descend as well, and at S2, the sintered part A is chamfered.
