无头铆钉双面鼓形镦头铆接试验及缺陷研究
Research on Riveting Tests and Defects of Headless Rivet with Double Drum Upsetting Head
摘要: 为分析无头铆钉双面鼓形镦头缺陷产生原因，首先分析无头铆钉铆接工艺流程，然后进行Φ4、Φ5铆钉的工艺试验，得出不同直径、不同试件厚度的铆钉建议长度。通过铆接完成后缺陷实物图从工艺流程和工艺试验中分析缺陷产生原因，并给出预防措施。
Abstract:
In order to analyze the cause of the defects of the headless rivet with double drum upsetting head, the process flow of the headless rivet is analyzed first. Then the rivet technology test with diameter 4 and 5 is carried out to obtain the recommended rivet lengths with different diameters and different specimen thicknesses. The causes of defects are analyzed from the process flow and process test, and the preventive measures are given.
