Sealing-Spinning Technology for Thin-Walled Aluminum Alloy Tubes
Thin-walled aluminum alloy tubes can be used as rigid sampling tubes in aerospace and geological exploration and other scientific researches. In order to ensure the scientific value of samples and isolate the external environment, two sealing ends of the rigid sampling tubes are required. In this paper, the sealing-spinning process is adopted to form two sealing ends of the thin-walled aluminum alloy tubes. The results show that rigid sampling tubes with good sealing quality can be formed by controlling the main technical parameters of sealing-spinning process. And the relationships between spinning load and feed rate of roller, spinning load and shape of roller, reducing ratio of wall thickness and feed rate of roller are found.
