Abstract (en)
[origin: WO2022043037A1] The invention relates to a device (10) for inserting an auxiliary joining part (22) into a workpiece (8), wherein the auxiliary joining part has, in a portion to be pressed into the workpiece, a circular circumference with a first, maximum diameter, having a die (14) for applying to an underside of the workpiece while the auxiliary joining part is being pressed in, wherein the die has a contact region (24) and a recess (26) surrounded by the contact region, wherein an edge (28) of the recess differs from a circular shape, wherein the outermost portions, in a radial direction, of the edge of the recess lie on an imaginary circumscribed circle (34) and wherein innermost portions, in a radial direction, of the edge of the recess lie on an imaginary inscribed circle (36), wherein the edge of the recess has at least three protrusions that project into the circumscribed circle of the recess and wherein the protrusions touch the inscribed circle, in which a diameter of the inscribed circle is between 4% and 10% smaller than the first diameter of the auxiliary joining part and in which a diameter of the circumscribed circle is between 2% and 5% larger than the first diameter of the auxiliary joining part.
