一、前言 铝合金压铸轮辐对我国尚属较先进的工艺,而在美国、日本等国家却已是相当成熟,并广泛用于轻便摩托车和汽车工业,以代替钢筋辐条编织轮辐的繁琐落后工艺。我厂根据美国大东公司提供的奥地利Puch公司生产的PuchⅡD1.35×170 DOL规格的样品进行了测验、设计并试生产。所试材料是两种成分的铸铝合金,一是按所化验的原样轮(以下简称A轮)的主要成分配制的(以下简称B轮),一是我国的ZL104(以下简
I. Introduction Aluminum alloy die-casting spoke is still a relatively advanced technology for our country, but in the United States, Japan and other countries are already quite mature, and is widely used in light motorcycles and the automotive industry, in lieu of rebar spoke braid tedious backward technology . According to Puch ⅡD1.35 × 170 DOL specifications produced by Puch Company in Austria supplied by Dadong Company, our factory tested, designed and put into trial production. The materials tested are two kinds of cast aluminum alloy, one is prepared according to the main composition of the original sample wheel (hereinafter referred to as A wheel) (hereinafter referred to as the “B wheel”), the other is ZL104
