目前,具有较多优势的轻合金材料已逐步广泛的应用于各个领域,特别是伴随着汽车、摩托车制造业的发展,铝合金材料成形及其车轮制造业得到了前所未有的发展机遇。21世纪的经济全球化浪潮,推动了汽车工业的市场一体化、分工专业化、产业规模化的快速发展,铝合金车轮企业也已形成向多家汽车厂供货、跨国供应的局面。然而,在我国铝车轮自主发展进程中,始终有技术瓶颈制约并伴随着产业发展的左右,即受制于关键制造装备。汽车铝轮毂的最主要的
At present, light alloy materials with more advantages have been widely used in various fields. Especially with the development of automobile and motorcycle manufacturing industries, aluminum alloy materials forming and wheel manufacturing have seen unprecedented development opportunities. The tide of economic globalization in the 21st century has promoted the market integration of the automobile industry, the specialization of labor division and the rapid development of industrial scale. The aluminum alloy wheel enterprises have also formed a supply and cross-border supply to many automobile factories. However, in the process of autonomous development of aluminum wheels in our country, there are always technical bottlenecks and accompanying industrial development, which are subject to the key manufacturing equipment. The most important of automotive aluminum wheels
