  • Punch rivet and method for producing a punch-riveted joint
    Patent number: 10927875
    Abstract: A punch rivet for joining two workpieces, has a head and a shank. The shank is hollow with a shank internal diameter (D3), a shank external diameter (D1) and a shank end face. On the shank end face is a ring cutting edge with diameter (D4) that is smaller than the external diameter (D1) but greater than the internal diameter (D3). The ring cutting edge is radially spaced both from the shank external diameter (D1) and from the shank internal diameter (D3) by at least 20% of the radial shank wall thickness (M5). And the ratio D3/D1 of shank internal diameter D3 to shank external diameter D1 is smaller than 0.6. And the external diameter (D1) merges into an external circumference of the head by a second profile, which defines an underhead radius (R1), and the ratio of R1 to D1 (R1/D1) is smaller than 0.13.
