Abstract

PURPOSE:To prevent burr generation at the bottom of a rivet leg by fitting a contact material in a die having a knockout pin in the center, which is equipped with a ring-shaped boss inside at the periphery of the tip face, and forming a head preliminarily with a punch. CONSTITUTION:A contact material 6' is fitted in a die 5' having in the bottom center a knockout pin 4' equipped with a ring-shaped boss 4'a tapered inside at the periphery of the tip face, and a head is formed preliminarily by a punch 7. Taper 10' is formed at the periphery of the leg bottom, and then the head is finished with another punch 11. This permits easy processing of a rivet contact of good quality tapered at the leg bottom without generation of burrs at the leg bottom, that permits easy and quick setting of the contact material to the die to lead to enhancement of the operating easiness.
