<p>PROBLEM TO BE SOLVED: To provide a sizing press machine capable of stably holding sintered bodies, each of which has a flange, in through holes and smoothly performing sizing processing.SOLUTION: There is provided a sizing press machine comprising a turntable in which a plurality of through holes housing sintered products, in which a flange is formed in a part of a thickness direction, is formed in a circumferential direction, and which receives the sintered products on a sintered body supply stage, rotates about an axial line, moves the products to a sizing station where pressing by punching is conducted. The machine comprises: a holding part 33 holding the sintered product; and a drive mechanism 50 which is connected to the holding part 33 and moves the holding part 33 forward and backward with respect to an inward direction of the through hole. The tip of the holding part 33 is positioned below the flange in a forward moving state in the case where the sintered product is housed in the through hole, and is made movable in an outward direction from the flange in the case of moving backward by the retracting means.</p> |
