摘要
Abstract
To solve the problems of poor quality consistency and low reliability of traditional pneumatic hammering interference sealing riveting,the research on the process parameters of electromagnetic sealing riveting was carried out.Taking ZL114A cast aluminum alloy as a typical material,the orthogonal test method was adopted with hole-making accuracy,notch form,and head form as variables and the performance of test pieces was tested based on the sealing performance after riveting.The results show that the leakage rate of the specimen is the lowest and the sealing performance is the best under the conditions of H8 bottom hole accuracy,convex head and double-angle notches,and the north form had the greatest impact on the sealing performance.Further analysis of leakage rate and interference amount measurements shows that test specimens still meet sealing requirements even when the interference amount does not meet the self-sealing riveting standard requirements.Therefore,from an engineering application perspective,the interference amount requirement can be relaxed to 0.4％under specific conditions.关键词
