中文摘要 | 流旋型(Tube Spinning)是一種金屬塑性成型加工,成件具有高尺寸精度、高強 度及良好的表面光度,此加工方法適於航太與軍事工業的高精密零組件的要求。本研究以逆 流旋型( Backward Tube Spinning )製造燃燒管(管形件), 並施以熱機處理( Thermomechanical Treatment ),製程中包含旋型加工、退火、固溶和時效等處理, 本研 究提供一種正確選取旋型及熱機處理製程參數的方法,使成件拉伸強度大為提升,並保有適 當延伸率。經由成管機械性能測試、尺寸量測及液壓測試,可驗證其優異的尺寸精度及機械 性能。 |
英文摘要 | Tube spinning is a metal plastic deformation process. This technique consists of the elongation of a thick-walled preform using shaped rollers to fabricate a thin-walled workpiece with high precision, high strength and good enough surface roughness. The fabrication can satisfy the requirements of aeronautical and military components. This article describes the fabrication of motorcase using backward tube spinning. The thermomechanical treatment involves proper control of the tube spinning and heat treatment processes, such as annealing, solution and aging treatments. By choosing the parameter of tube spinning and thermomechanical treatment processes, the mechanical properties and dimension precision are improved. The performance of the finished products including the higher strength with proper elongation and good mechanical behavior are verified by mechanical and hydraulic test. |
