模锻铝制构件和组件在机车车辆结构中的应用为减轻机车车辆质量作出了重要贡献。近几年来,模锻铝制构件的成形能力有了很大的改善,并开发了一些可高强度时效硬化的新合金。本文介绍了模锻铝制构件在可以达到的一些特性及其在结构上必须注意的一些最重要的成形参数,对钢和铝的其他不同的制造方法也进行了比较。以关节列车中关节部分为例,对2个模锻主组件的设计与优化过程、质量保证、检验进行了介绍,同时还对包括成品加工和安装后的关节模块在内的生产过程也作了说明。该工艺若在研发阶段就以其相关零件的结构特性和成形能力一起纳入总设计,则会带来很大的优越性。
The application of die-forged aluminum components and components in the structure of rolling stock has made an important contribution to the reduction of the quality of rolling stock. In recent years, the ability to form aluminum die-forged parts has greatly improved and new alloys have been developed that can age harden with high strength. This article describes some of the features that can be achieved with die-forged aluminum parts and some of the most important formative parameters that must be noted in the structure. Other different manufacturing methods for steel and aluminum are also compared. Taking the joint part of the joint train as an example, the design and optimization process, quality assurance and inspection of the two main components of the forging are introduced. The production process including the finished product processing and the mounted joint module is also made Description. If the process is incorporated into the overall design with the structural characteristics and formability of its associated parts during the R & D phase, this process offers significant advantages.
