Geometrical parameters and strength of clinching joint formed with the use of an additional rivet

Abstract In the publication, results of an experimental analysis joint formation by pressing DX51D steel sheets with thickness 1.5 (mm) use a rigid punch and additional deformable rivet various shapes were presented. The influence diameter d = 5 (mm), similar to dimensions forming in case classic clinching variety on interlock parameters was investigated. used die four movable segments—dedicated connections made clinch-riveting technology TOX ® PRESSOTECHNIK. additional, tests for joining shapes, i.e. through hole. Joints formed correctness upper blockage lower sheet observed joints cross-sections. measured each samples. order compare using strength traditional also made. minimal embossment 2 X 0.75 (mm).
