基于Pr-E的小型汽车前副车架上板的成型工艺及模具设计 摘要 随着现代化社会的日益发展，能源也是越来越紧缺，所以环保的行业成为现在发展的重中之重。冲压模具就是其中一种可以循坏利用的工业。模具的应用的范畴极为广泛，在很多的轻工业当中，许多的零部件都需要依据模具才能够被生产出来，而且伴随着人们的各种需求，越来越需要冲压模具来带给我们便利。当前的社会，冲压模具的发展、精密度以及模具的使用寿命，已经是衡量一个国家机械化水平的最具有影响力的标杆。大到汽车的覆盖件，小到单手掌控的3C数码产品，都离不开冲压模具的发展。随着对产品质量的提高，也需要对模具结构的精确度来进行严格规范，从而实现模具的高效发展。模具的级数比较前沿，当前已经融合了机械工程、计算机应用、自动操控、数控技术等产业，是一种比较具有综合性的学科。 在此次的设计当中，我翻阅查看了大量的模具设计资料，在汽车前副车架上板模具的设计与应用当中，和以前的设计方法相比较而言，模具的广泛应用，使得产品的质量得到了巨大的提升，模具的创新思路以及要求要紧跟现代化的步伐下，需要与未来的发展相结合。 关键词：冲压，数码，车架 the small car based o
