Abstract
A method of forming one or more tie rods that includes flattening a main body of a wire in a first selected plane to form a flattened main body, further flattening selected portions of the flattened main body in a second plane perpendicular to the first plane to form one or more break back regions, and then passing the wire through a punch press machine to form one or more coined regions in one or more ends of the wire, thus forming the tie rod.

A method of forming a tie rod, comprising:
- flattening a main body of a wire formed of a selected material in a first selected plane to form a flattened main body,
- further flattening selected portions of the flattened main body in a second plane perpendicular to the first plane to form one or more break back regions, and
- passing the wire through a punch press machine including a first die having a first protrusion and first immediately adjacent flat extended coining region, and a second die having a second protrusion and a second immediately adjacent flat extended coining region;
- wherein the first die and second die oppose each other, and the first and second coining regions and opposing surfaces of the first and second protrusions are parallel to each other, and wherein the first and the second protrusions and the first and second coining regions are offset from each other in a direction of wire travel to form one or more flattened coined regions in one or more ends of the wire and to sever the wire;
- moving the first and second opposing dies towards each other such that the first and second protrusions contact the wire to crimp and cut the wire, and
- simultaneously pressing the wire between the first and second flat extended coining regions to stamp and press the wire to form the flattened coined regions thus forming the tie rod, wherein the flattened coined regions are axially spaced apart from the crimped and cut region of the wire.
