Performance Features of Hollow Drive Shaft Forgings, Forged Components & Factory Customization
Performance Features of Hollow Drive Shaft Forgings
Composite Process of Upsetting - Piercing - Mandrel Drawing
Adopting a multi-stage forming process with a forging ratio ≥4.5, combined with staged temperature-controlled heating at 1150-1200℃, the mandrel feed rate and reduction are controlled to ensure continuous distribution of metal flow lines along the axial direction of the shaft body, with no eccentricity or folding defects in the inner hole, wall thickness difference ≤1.5mm, and metal density ≥99.8%.
Customized Heat Treatment Strengthening
Implementing the composite process of "overall quenching and tempering + journal surface quenching", the internal stress elimination rate is ≥98%, the overall hardness of the shaft body is HB220-260 to ensure torsional toughness; the hardness of the journal and spline working surface reaches HRC50-55 to improve wear resistance, and the fatigue life meets working condition requirements.
High-Precision Quality Control and Inspection
Key dimensional tolerances reach IT7-IT8 grade, coaxiality ≤0.1mm/m, inner hole roughness Ra≤3.2μm, straightness ≤0.2mm/m; passing ultrasonic testing (UT) and magnetic particle testing (MT), meeting the Grade II requirements of JB/T 1265-2014 Technical Conditions for Large Shaft Forgings, focusing on detecting defects in stress concentration areas such as inner hole walls and journal transition zones.
