Abstract: The rivet feeding system is a significant component of automatic aircraft panel drilling and riveting machines, and plays an important role in working efficiency and reliability of riveting. The pneumatic feeding system with the hosepipe for sunk head rivets is analyzed, and the rivet's motion, the interior diameter and inlet pressure of the feeding tube are studied considering the shape of sunk head rivets. The optimal interior diameter is obtained by analyzing rivet jamming in the bending tube and drag coefficients of rivet feeding. An appropriate inlet pressure is calculated by a theoretical analysis of the pressure loss of rivet feeding as well as the feeding time. The method for choosing the interior diameter is verified through the experiments on rivet feeding with different interior diameters, and the method for calculating the inlet pressure is verified through the experiments on rivet feeding with different inlet pressures.

Key words: rivet feeding, rivet's motion, tube interior diameter, analysis of rivet jamming, pressure loss, feeding air pressure
