摘　　要：为解决镁、铝合金车轮轮辋无法空腔旋压问题,提出了镁、铝合金轿车车轮轮辋空腔热旋压新技术。此技术将旋压模具和旋压毛坯分别加热到要求温度,提高旋压毛坯变形塑性,分别按照镁、铝合金热变形塑性特点,编制新的旋压程序,使得热旋压后车轮轮辋内壁形成空腔,达到完成热旋压新技术的目的。此技术成功实施,为企业工艺技术进步提供了技术保障,减少了不必要的材料损耗,降低了成本,提高了生产效率。To solve the problem that magnesium,aluminum alloy wheel rim can not implement cavity spinning,the magnesium-aluminum alloy car wheel rim cavity hot spinning technology is proposed.During which spinning mould and spinning blank need to be heated respectively to the required temperature in order to improve the spinning blank deformation plasticity.According to the magnesium-aluminum alloy thermal deformation plasticity characteristics,new spinning program was made to form hot spinning wheel rim wall cavity for the goal of complete hot spinning technology.This technique provides the technical support for the enterprise technology progress,reduces the unnecessary material loss,and improves the production efficiency.
