摘　　要：为使ZD6型转辙机挤切销具有符合使用要求的机械性能,确保转辙机的正常运行及道岔出现卡阻故障时挤切销能及时断裂,起到对ZD6型转辙机的整体保护作用,研究了3种材料、6种孔径,以及用4种不同热处理工艺处理后的挤切销机械性能。结果表明以20号钢为原材料制作,并经过退火工艺处理的挤切销性能最好、生产成本较低,且最符合使用要求。The dissectible pins in the ZD6 type switch machine should have mechanical properties in line with the requirements of use, which can not only ensure the normal operation of the switch machine but also provide overall protection for the ZD6 type switch machine by timely fracture of the dissectible pins when the turnout is stuck. Therefore, the mechanical properties of the dissectible pins are studied using 3 kinds of materials in 6 kinds of pore diameters under 4 different heat treatment processes. The results show that annealing process with 20# steel as raw material can achieve the best performance and lower production costs and meet the requirements best.
