摘要：

传统锻造铝轮毂一般采用开式模锻成形工艺。设计了闭式模锻模具结构，并对铝轮毂闭式模锻成形工艺进行了研究，针对成形过程中易出现的充形不饱满、窗口折叠、脱模变形等常见缺陷，进行了分析，并有效地解决了问题。研究结果表明，旋转锻毛坯随形定位、模具关键部位圆角R、脱模退料结构对成形工艺有直接影响。铝轮毂闭式模锻工艺可行，目前已进行批量生产应用。

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.
