A Pinion Drive, And A Forging Process And An Apparatus For Making It
Abstract: A Finisher Die Assembly And A Forging Process To Make A Pinion Drive, And a Pinion Drive Abstract: Conventionally, pinion drives are manufactured using multistep processes such as casting or forging, followed by various machining processes, and have shortcomings such as significant wastage of material and resources, requirement of precision tooling, cutting of the grain flow lines resulting in the grain flow lines that are neither continuous nor follow the profile of the teeth, resulting in pinion drives of lower strength and life, and cumbersome ejection mechanisms. The invention discloses a method of producing as-forged near net shape pinion drive having as forged gear teeth with continuous grain flow lines conforming to the profile of the teeth, using sequential forging operation, and a finisher die assembly that ensures automatic and easy ejection of forged part. The process of invention involves deployment of a finisher die assembly which is designed to provide a gap between the top surface of the top finisher die and corresponding inside surface of the top finisher die holder of the assembly. Representative figure: Figure 3.
