Abstract：

In order to study the synergistic effect of die parameters on joint performance during the clinching process with extensible dies, a finite element model of clinching process with extensible dies for Al5052 aluminum alloy was established by finite element software Abaqus, and the connection process was numerically simulated and analyzed to obtain the information of equivalent stress field, movement speed of sliding die and so on during the joint forming process. Then, the influences of die depth, die radius and preload of sliding die on the geometric parameters of joint were studied. Finally, the synergistic influence of these three factors on the geometric parameters of joint was comprehensively analyzed. The results show that the addition of the preload of sliding die changes the original influence of die radius and die depth on the interlock value of joint, and applying a certain preload of sliding die can improve the mechanical interlock of joint and the mechanical properties of joint. Thus, the influence of die parameters on the joint forming lays a foundation for the research and application of the clinching process with extensible dies for aluminum alloy.
