中文摘要 | 粉末鍛造製程為結合傳統粉末冶金及鍛造之複合成形製程,即是將經由傳統粉末 冶金技術而得之預成形胚,以熱間鍛造方式於密閉模穴之鍛模中鍛打而成形。粉末鍛造零件 除可具有如鍛鋼 (Wrought Steel) 材料零件同等之機械及物理性質外, 且亦具有如粉末燒 結零件於複雜形狀及尺寸之良好精度控制等優點。本文敘述棘輪軛粉末鍛造製程研究中所進 行之相關實驗過程及結果; 結果顯示, 當粉末燒結預成形胚於氮氣氛下加熱至 1100 ∼ 1150 ℃時進行鍛打, 具有良好之鍛造成形性,而所得之鍛件其密度可達 7.81g/cm �� (理 論密度約 99.8%) 且具有良好之尺寸精度。 |
英文摘要 | Powder foraing is a hybrid process in which preforms made by conventional PM techniques are hot forged in closed impression dies. The powder-forged components can be produced having mechanical and physical properties equivalent to conventionally wrought steels, together with the complexity and dimensional accuracy normally associated with sintered parts. The paper describes some investigations on powder forging of the ratchet head. The results showed the proforms should be heated to 1100 ∼ 1150 ℃ in N2 atmosphere in order to have good forgeability. The density of the forging parts reached 7.81 g/cm3 (theoretical density ≒ 99.8%). |
