蒸汽机车扁弹簧组是由若干片弹簧组成的,片与片之间靠弹簧套来紧固。弹簧套是在加热状态下,用液压机套装在弹簧上的。装套工序中崩套现象时有发生,不仅浪费人力、物力和工时,而且影响落车,贻误生产进度。因此,必须采取预防措施。一、崩套原因浅析在长期生产实践中,我们摸索出崩套有 Steam locomotive flat spring group is composed of a number of pieces of spring, between pieces and pieces by the spring sleeve to tighten. Spring case is in the heating state, the hydraulic machine sets on the spring. The phenomenon of collapsing occurs in the process of nesting, which not only wastes manpower, material resources and working hours, but also affects the process of getting off the vehicle and the production progress. Therefore, precautionary measures must be taken. First, the collapse of the causes of analysis In the long-term production practice, we explored a collapsed set
