Abstract：

Based on the needs of rapid manufacturing of sample piece and waterproofing of riveting, a split rivet was designed. Then, for the riveting forming of two layers of Al6016-T4 aluminum sheet with the thickness of 1.5 mm, taking the height and inner diameter of rivet head, inner diameter of rivet leg and blank holder force as the influence factors, and taking the interlocking length as the evaluation index, the riveting forming process parameters of split rivet were optimized by the orthogonal test of four factors and three levels and the software Deform-2D. Range analysis show that the influence order of process parameters on the interlock length is inner diameter of rivet leg>height of rivet head> inner diameter of rivet head > blank holder force. Then the optimal riveting parameters were obtained based on the analysis result of orthogonal test, and the optimization scheme was verified by experiments. The relative error between the simulated and experimental values is 8.69%, indicating the accuracy of the simuletion results, which hes guiding implications for the actual production.
