About Resistance Performances of Round Clinch Processed by the Joining Sheet Metal in One-Piece-Die

Résumé

The paper presents the clinching joint and some experimental determinations of the resistance performances of round clinch processed in one-piece-die. The experimental research was made on different tickness steel fastened sheets and the clinching point in transversal and axial direction with shear tensile test pieces and peel tensile streght pieces was mechanically tested. The paper is also concerned with experimental determinations and the performances of joint after the repression operation. It was obtained same results with practice utility concerning press joining steel and resistance of joint clinched depending on sheet thickness and diameter size.
