KeyWords： Study on closed-die forging technology of forging aluminum alloy wheel Ma Zeyun CITIC Dicastal Co. Ltd. Abstract: The traditional technique of forging aluminum wheels is mostly open-die forging. The mould structure of closed-die forging was designed and the study on the forming technique of closed-die forging for aluminum alloy wheel was conducted. The analysis on the common defects during forming such as unfilled filling form folding wheel windows and demoulding deformation was made and then solutions were put forward effectively. Research results show that positioning rotary forging blank with the shape the radius R of mold in the key location and the structure of demoulding and unloading have a direct influence on the forming process. The closed-die forging process of aluminum wheels is feasible and it is applied to the mass production of aluminum wheels. Key words: forging aluminum wheel closed-die forging rotating forging blank die radius R structure of demoulding and unloading
