Abstract
PURPOSE: To produce a bevel gear which has no under-fill on the tooth profile small diameter side and has sufficient tooth strength and good shape accuracy by pressure- moving a set of punches simultaneously in opposite directions, and providing a speed difference in the movement of both punches.
CONSTITUTION: A circular cylindrical forging blank material W is put into the cavities 12, 13 of upper, lower dies 10, 11, and the dies are registered. An upper punch 14 and a lower punch 15 are pressure-moved simultaneously in opposite directions, and the moving speed of the upper punch 14 is set higher than the moving speed of the lower punch 15. When forging pressure is acted upon the blank material W by this speed difference, the lower part on the side opposite from the upper punch 14 bulges and gradually fills the cavity 13 of the lower die 11, thereby assuming the shape conforming to the molding surface 13a and forming a tooth profile small diameter side 20a without underfill. Thence, the bulged part of the blank material W shifts to the upper part, and a tooth profile large diameter part 20b is formed. With this method, the bevel gear having no decrease in tooth strength is formed by one time of process.
