[0045] According to the drawings, first the first metal plate 1 and the second metal plate 2 are arranged to be connected to each other and form an assembly. The first metal plate 1 shown and the second metal plate 2 shown here both consist of high-strength steel. The two metal plates have a thickness of about 1.5 mm.
[0046] Next, the first metal plate 1 and the second metal plate 2 are introduced into the punching riveting assembly tool 3. The piercing riveting tool 3 includes a feeding protrusion 4 in which a punch is arranged. The feed protrusion 4 guides the punch 5, and the punch rivet 6 is provided at the bottom end of the punch 5. The feed protrusion 4 in which the punch 5 is positioned and the guided perforated rivet 6 are located on the assembly for connecting the first metal plate 1 and the second metal plate 2 together. Under the component to be connected is a mold 7.
[0047] After the first metal plate 1 and the second metal plate 2 are introduced into the perforati...
