Abstract

Method for the production of semi-perforated rivets, characterized in that it comprises the introduction of a portion of wire in a corresponding internal cavity of a fixed matrix in which a pin of lower cross-section is introduced to said wire portion, the advance and the introduction into said die cavity of a first punch able to push said portion of wire against said pin so as to make a substantially axial hole in correspondence with the end of the wire portion facing said pin, the retraction of the first punch, a first advance of the shank to bring out the non-perforated end of the wire portion to the outside of the die, the advance of a second enlarged head punch to crush said non-perforated end of the wire portion against the outer surface of the wire. The die to make an enlarged head in the wire portion, the retraction of the second punch, a second advance of the spigot to make the rivet thus formed leave the matrix, the hooking of the rivet by means suitable to prevent its movement towards the matrix and finally the retraction of the spindle towards its initial position of maximum recoil.
