一、概述由于我厂产品品种越来越多 ,相应的模具及费用也在递增 ,针对一个圆弧及含直边的轮盖 ,根据金属材料塑性成型理论 ,运用了一种简易的成型方法 ,并获得成功。二、轮盖成型关键点的计算根据需要成型的轮盖的理论尺寸 ,以及金属材料塑性成型原理 ,计算出Ａ、Ｂ、Ｃ三个关 First, an overview Because I plant more and more varieties of products, the corresponding mold and costs are also increasing, for a circular arc and with straight edge of the wheel cover, according to the metal material plastic forming theory, the use of a simple molding method, And be successful. Second, the calculation of the key points of wheel cover forming According to the need to shape the theoretical size of the wheel cover, as well as the plastic forming principle of metal materials, calculated A, B, C three off
