发明名称 HOHLNIETVERBINDUNG ZWISCHEN ZWEI BLECHEN UND VERFAHREN ZU IHRER HERSTELLUNG
摘要 The invention relates to a tubular rivet connection between at least one first ( 1 ) and one second metal sheet ( 2 ). According to the invention, the tubular rivet ( 3 ) is made from the metal of the first metal sheet ( 1 ) by deforming, in a drawing direction (Z), the edge area of a first hole ( 4 ) located in the first metal sheet ( 1 ) into a second, larger hole ( 5 ) located in the second metal sheet ( 2 ), whereby the second hole ( 5 ) located in the second metal sheet ( 2 ) is, in particular, gradually enlarged with regard to its diameter in the drawing direction (Z). The invention provides that the tubular rivet ( 3 ) is shorter in length in the drawing direction (Z) than the thickness of the second metal sheet ( 2 ). To this end, the thickness tolerance of commercially available metal sheets is taken into account and damages to the tools and/or the formation of chips is/are prevented. With regard to the method for producing such a tubular rivet connection, the invention provides that the second metal sheet ( 2 ) is supported by a matrix, which has a diameter approximately corresponding to the diameter of the hole ( 5 ) in the second metal sheet ( 2 ).
