Material-specific predicting of the optimal joining parameters for the screw blind rivet joining process

Abstract The screw-blind riveting combines direct screwing with the blind riveting. novel joining element can be integrated into every injection-molded component like a standard screw boss without significantly increasing processing time. screw-blind-rivet (SBR) consists of connected to substrate by thin sleeve. process screw-blind-riveting divided two phases. first is screw-in phase. secured SBR. second phase forming Further turning will cause sleeve buckle out and form an undercut. To qualify connection for industrial use, in addition strengths design, suitable parameters are required user. independent contact pressure screwing-in speed. rate reduced avoid damage ensure proper alignment. speed after headrest additional influencing parameter. most parameter undercut rotation angle initial placement as it affects shape larger is, more stable rivet. However, deformations material occur. Thus, optimal depends on Consequently, deformation must selected depending properties. For this, various materials were tested. results show well predictability optimum using elongation at yield stress used material.
