Abstract

Machine for the automatic manufacture of wire-based bimetallic contact rivets by means of cold welding, in which a perforated matrix in reciprocating motion is loaded successively from the same side with the pieces of wire necessary for the manufacture of a rivet , which it separates itself from the provision by means of its transversal movement, characterized by a fixed perforated matrix that collaborates with the movable matrix and in which the pieces of wire with the piece of copper forward from the movable matrix are pushed by a needle penetrating said die against an anvil needle in a fixed die and cold-welded by pre-upsetting within a turned cavity of the fixed die over the needle section, after which, after removal movable matrix a buterola finishes forming and welding the rivet inside the fixed matrix, this being then expelled by the anvil needle.
