Abstract

PURPOSE:To make a tooth part of good shape having no underfill nor wrinkle by forming the truncated conical edge part of the preform for a bevel gear in the max. diameter part connected to the underfill edge and by maintaining a sufficient gap with a die bottom face by the tip of the preform abutting to a tooth die at the complete insertion time to a forming die. CONSTITUTION:At the time when a preform 2 is made by inserting and upsetting a preform 1 to the preforming lower die 5 of a bevel gear, an underfill edge 3 is formed at the apex part connected to the truncated conical part 4 thereof and the max. outer diameter composed by the both is made equal to the inner diameter of the cylindrical part 12 of a forming die 11. In the case of inserting this preform 2 into the forming die 11, a sufficient gap is made to exist between the tipeface 8 of the preform 2 abutting a tooth die 13 and a die bottom face 14. With the pressforming by descending a punch 10 in this state a metal structure is smoothly flowed to the tooth die 13 and a complete gear is formed to make a bevel gear in a good product without underfill and wrinkle generations on a tooth part nor burr generation.
