摘要: 研究了摩擦铆接设备的不同主轴动力参数对AA2024-T351铆钉/PEI ULTEM-1000母材摩擦铆接工艺镦头形态的影响。铆钉旋转速度、铆钉铆入速度、下压距离和急停速度是铆接镦头主要工艺参数,研究结果表明:铆钉旋转速度越高,摩擦铆接连接区域热输入越多;铆钉铆入速度过小,会出现铆钉逐渐深入钻削的现象,影响热量在铆钉和母材接触区域的积聚,铆钉铆入速度过高,热量还未来得及产生,铆钉材料就被撞弯;下压距离和急停速度可以调控摩擦铆接工艺镦头连接紧固效果。

Abstract: The effects of friction riveting equipment different spindle movement parameters on the riveting-heading morphology of AA2024-T351/PEI ULTEM-1000 friction riveting processes were studied. The results show that the main technological parameters of riveting-heading are rivet rotating speed, riveting press-in speed, press-in distance and stop procedure speed. The higher the rivet rotating speed, the greater the heat input in the friction riveting connection area. If the riveting press-in speed is too small, the rivet will gradually penetrate into the drilling processes, affecting the accumulation of heat in the rivet and base metal contact area; riveting press-in speed is too fast, firstly the heat is not yet generated, rivet materials are bent. The smaller press-in distance and stop procedure speed may regulate the fastening effectiveness of the riveting-heading in the friction riveting processes.

Key words: heterogeneous material structure, lightweight, friction riveting, spindle process parameter, morphology of riveting-heading
