Abstract

Method for forming a self-drilling mandrel applicable to the placement of rivets in rivet assemblies without a nose piece and comprising a head, a pull shank and a piercing portion, by upsetting a portion of wire to form the head of the mandrel and forming the piercing portion on the side of the head opposite the pull rod, characterized by forming the mandrel head as a collar (12, 12', 12'') arranged around the wire, so that on one side A pin (18) protrudes from the collar and that the pull rod (16) protrudes from the other side of the collar (12, 12', 12''), and because, to form the piercing portion (26), the dowel (18) to a crushing operation until a flat sheet (20, 20', 20'') is obtained that contains the axis of the dowel (16) and extends diametrically at least to the periphery of the collar (12, 12', 12'').
