Abstract

PURPOSE:To improve the accuracy of products by inserting a blank material in a die for a bevel gear, pressing the same while restraining the outside circumference and filling the material in the open cavity at the leading end from a circular conical bottom part thereby discharging scale, etc. from the open cavity. CONSTITUTION:An annular blank material 11 is inserted into the container 12 of a die 10 engraved with a tooth profile part of a bevel gear, and is pressurized with a punch 16 from the top surface thereof. At this time, the material 11 is restrained by the inside circumferential wall of the container 12, and is forced in the direction of a tooth profile part 13 by the pressure of the punch 16 in a forward extrusion system. At the same time, the material 11 flows plastically from the upper part of the part 13, that is, from the outside circumferential side deddendum 13c of the part 13 to a conical leading end part 13, thereby filling the inside of the part 13. In the final stage of the press-forming with the punch 16, part 11b of the material 11 overflows the part 13a and is extruded into an open cavity 14.
