Background
In aircraft design, titanium alloys and composites are used in large quantities in order to increase aircraft structural strength and fatigue life while reducing aircraft weight. However, the application of the hot riveting process is greatly limited due to the composite material causing mounting damage and delamination phenomena. In order to make the skin of the outer surface of the airplane relatively smooth, the selection of a proper riveting process is crucial, so that stress concentration can be better eliminated, and the reduction of air resistance of the airplane in high-speed flight is more facilitated.
Due to the limited structural openness, the traditional high-power riveting press cannot be applied under many conditions, so that only a traditional small pneumatic riveting gun can be adopted, and the problems of unstable riveting quality and low riveting efficiency of the pneumatic riveting gun exist.
Therefore, related technicians develop electromagnetic riveting guns in succession, can utilize electromagnetic energy to finish rivet upsetting, and belong to a brand-new high-energy riveting process. The electromagnetic riveting gun specifically utilizes strong thrust generated by electromagnetic eddy current and carries out upsetting forming on the rivet by one-time impact. The energy released by the high-energy pulse power supply is converted into stress pulses through the coupling coil, the rivet can be deformed within millisecond time due to the extremely high loading rate of the stress pulses, the rivet material can uniformly and synchronously flow in all directions during riveting due to the high loading rate, ideal interference fit can be realized, the rivet has good riveting effect on the rivet which is difficult to form and has high yield ratio, sensitive strain rate, high strength, large diameter and the like, and the rivet is more suitable for riveting of titanium alloy, composite materials and thick sandwich structures.
