摘要: 针对1420铝锂合金材料通过对手工锤击铆接和自动静压铆接两种加工方式形成的铆接接头进行力学性能对比分析，试验内容主要包括铆接接头剪切试验、拉脱试验，根据试验结果和理论分析得出结论：自动静压铆接工艺性能优于手工锤击铆接。通过开展某型号产品工程化应用试验，充分验证了1420铝锂合金桁条自动钻铆的可行性、可靠性，从而极大提高产品的生产合格率和质量稳定性。
Abstract: Through comparing and analyzing the mechanical properties of the riveted joints formed by manual and automatic static pressure riveting for 1420 Al-Li alloy. The main contents of the experiment include the riveting shear performance and the riveting pull-off performance of riveted joints. According to the experimental results and theoretical analysis, it is concluded that the automatic static pressure riveting process performance is better than that of manual hammer riveting. By carrying out the engineering application research of a model product, the feasibility and reliability of automatic drilling and riveting of 1420 Al-Li alloy strings are fully verified, thereby greatly improving product qualification rate and quality stability.
