弹条是弹条工型扣件的重要零件。通过它的弹性变形,缓和列车在行进中的冲击能量和承受较大负荷,起固定轨距,减震缓冲的作用。弹条本身还能储存一定的能量,以保证轨枕,钢轨、扣件间足够大的扣压力。因此,弹条质量是直接关系到行车安全,线路稳定的重要零件。根据GB1222-75标准,弹条由60Si2Mn钢φ13mm热轧圆形弹簧钢制造,由于形状复杂,加工难度大,传统的生产工艺规程是:
Elastic strip is a type of fasteners important parts. Through its elastic deformation, to ease the impact of the train in the process of impact energy and withstand greater load, play a fixed gauge, damping buffer role. The bar itself can also store a certain amount of energy, in order to ensure that sleepers, rails, fasteners enough buckling pressure. Therefore, the spring bar quality is directly related to traffic safety, line stability of the important parts. According to GB1222-75 standard, the spring bar is made of 60Si2Mn steel φ13mm hot-rolled round spring steel. Due to its complex shape and difficult processing, the traditional production process is:
