Abstract
PURPOSE: To cheaply mass produce the polished nut, by forming the semifinished nut using the high accuracy hot nut former, and by removing the black oxide film and burr using the barrel polishing machine, followed by forming the female screw and the rust preventive treatment.
CONSTITUTION: The tip of raw steel bar 1 is inserted into the heating furnace A and is heated to a high temperature; next, the bar 1 is cut into the specified length by the cutter B, and is preparatorily formed into a cylinder fittable to the forming die D by the preparatory former C. This cylinder is pressure inserted into the forming die D by the pusher die D', and the greater part of the outer shape and center hole of the nut are formed. Next, the center hole 2 is pierced by the center hole piercer E, and the semifinished nut 3 covered by the black oxide film is obtained. This semifinished nut 3 is put into the barrel polishing machine F and is barrel polished using suitable medium and compound. After removing the black oxide film and the burr from the surface, the nut is water washed, and the female screw is cut in the center hole 2 by the screw cutting machine G, and finally the rust preventive treatment is applied using the rust preventive agent.
