中文摘要 | 汽車傳動軸等速接頭 (Constant Velocity Joint) 外輪 (Outer-race) 共有三大 類型,分別為 TJ 及 BJ。 傳統上業界均採用熱間鍛造或冷間鍛造製程,前者製程道次少但 鍛件精度較差,需配合大量後續機械加工;後者鍛件精度高,但卻需退火及磷酸鹽皮膜處理 ,製程道次多,成本相對較高,因此近年來技術發展即逐漸朝向應用溫 / 熱間鍛造 + 冷間 精整製程,可兼取二種不同製程之優點。本研究即以 TJ 鍛件為載具,建立 800 -850 ℃三 工程溫間鍛造 + 室溫冷間精整複合鍛造製程,結果顯示鍛件球軌精度達± 0.08mm,內徑及 球軌部位不再需機械加工,僅外徑局部機械加工後即可經熱處理並組裝成品,達到減少製程 道次,降低製造成本之目的。 |
英文摘要 | The outer-race of constant velocity joint for drive shaft of automobile has two different types, one is TJ (Tripod /Tripot Universal Joint) and the other is BJ (Bell/Ball Joint). Conventionally, People in industry use hot forging and cold forging technology to fabricate this kind of products. The former has less process steps, but the precision of forging parts is not good, so it needs much machining work! The latter can get precision forging parts, but because material is necessary to do annealling and phosphating during forging process, the cost is higher than hot forging. So the trend of technology is to use warm /hot forging + cold sizing recently, which combine the characteristics and advantages of two forging technologies. In this research, we develop hybrid forging process (800-850 ℃ 3 step warm forging + cold sizing ) for TJ. The result shows that precision of inner dimension for TJ can achieve ± 0.08mm and don't need any machining work, only outer dimension of TJ need a little machining work, then after heat treatment can be used for assembly. The advantages of this technology are reduced process steps and the manufacturing cost as well. |
