本文从铸造铝合金车轮的热旋压成形工艺出发,对A356材料的旋压性做了进一步分析,对车轮旋压模具与毛坯贴合程度、模具润滑方式、模具结构进行了数值模拟和试验验证。结果表明,选择合适的旋压温度能够避免由于旋压过冷而造成的车轮毛坯缺陷,模具热膨胀系数的正确选取、模具结构的合理设计对旋压成形工艺至关重要。 In this paper, the spinning process of A356 material is further analyzed based on the hot spinning process of cast aluminum alloy wheels. The numerical simulation and experimental verification are carried out on the degree of conformity between the wheel spinning mold and blank, the mold lubrication mode and the mold structure . The results show that choosing the proper spinning temperature can avoid the wheel blank defect caused by the supercooling of the spinning and the correct selection of the thermal expansion coefficient of the mold. The reasonable design of the mold structure is very important for the spinning forming process.
