根据铁路货车重载提速提出了采用锻造工艺制造钩尾框的要求。由于钩尾框形状复杂、体积庞大,导致其锻造的工艺难度较大。介绍了铁路货车钩尾框锻造工艺,包括工艺的分析、研究、制定和修整的全部过程。通过对不同的锻造工艺进行分析比较,提出了合理的锻造工艺方法,并成功地应用于17型和16型锻造钩尾框的生产。 According to the speeding of heavy goods vehicles, railway wagons are put forward to make the yoke frame by forging. Due to the complicated shape and size of the yoke, the process of forging is more difficult. This paper introduces the forging process of hook yoke of railway wagon, including the process of analysis, research, formulation and finishing of the craft. Through the analysis and comparison of different forging processes, a reasonable forging process method is proposed and successfully applied to the production of 17 and 16 forged yoke frames.
