Abstract
Abstract Spinning processing is used to produce the seamless liner of high-pressure hydrogen gas container. Currently, Al-Mg-Si alloys are applied for the hydrogen high-pressure gas container, where the formation of surface defects such as wrinkles and cracks on the inner surface of the liner is a crucial problem. In this study, spinning is performed on Al-Mg-Si (A6063) alloy by changing processing conditions. Then, surface defects and texture of test pieces affected by processing conditions. The results are followings, in the larger number of spinning pass, good surface properties can be obtained on the contacting surface of the roller. On the other hand, in the smaller number of pass, irregularities on the inner surface, the length of the processed portion, and the reduction of thickness are decreased. The decrease of irregularities on the inner surface may be caused by a small number of continuous deep drawing processes without decreasing thickness.The irregularities on the inner surface of test pieces are reduced by using the forming die.
