Abstract
PURPOSE: To perform chamfering and sizing of tooth faces of a gear simultaneously by constituting a male die with a chamfering die incorporating a punch and a female die of a sizing die provided with a chamfering die and an ejector in compression molding the gear from a sintered body.
CONSTITUTION: A pressure molding machine producing gears from sintered bodies is constituted of male and female dies respectively provided with chamfering dies and a punch and a sizing die and an ejector. In production, a sintered metallic body 27 is placed on the sizing die 24 provided to a low bolster, and is set in the posture wherein the top surface of an ejector 31 is located lower by a presccribed distance from the top surface of the die 24. A punch 6 secured to the upper bolster 1 via a pressurizing block 4 is lowered to size the body 27, at the same time, teeth are chamfered by the chamfering dies 10, 23 provided to the upper, lower bolsters 1, 19, whereby the gears of high dimensional accuracy are made easily mass produceable without requiring skill.
