Verfahren, Vorrichtung sowie Hilfsfügeteil zum mechanischen Fügen

摘要

The invention relates to a method for mechanically joining stacked, plate-shaped joining partners, especially metal sheets (4, 5) by means of punch riveting with a semitubular rivet (16) while using tools(7, 8) placed above and below the joining partners (4, 5), whereby the semitubular rivet (16) linearly penetrates into the joining partners (4, 5). The inventive method is characterized in that, during the axial feed motion of the semitubular rivet, the upper tool (7) and/or a portion (8) of the lower tool is/are subjected to a wobbling additional movement in a radial and/or tangential direction. The invention also relates to a device and to an auxiliary joining part (6) which are used for carrying out said method.
