Abstract
PURPOSE: To manufacture mechanically superior female thread with efficiency by fitting a base metal of nuts and the like that is provided with a bottom hole of the inside diameter corresponding to the root diameter of the internal thread, to a punch in the male thread form corresponding to the internal thread and by releasing the base metal from the punch after the internal thread was formed by pressing it from more than 2 directions of its periphery.
CONSTITUTION: A base metal 1 provided with a bottom hole 1a is placed on a machine stand frame 11, so as to fit it to a male thread punch 3 with the bottom hole 1a. Then a die case 12 is lowered to cause each forging die 14 to meet to the outside periphery of the base metal 1. Next, when the die case 12 is strongly pressed to go down, the die 14 tries to go up relatively in a taper hole 13, is pushed toward the base material 1 by the taper face, and to the base metal 1, a strong forging force in the directi?n going to the punch 3 is applied simultaneously from the the circumference. Through this, on the bottom hole inside peripheral face fo the base metal 1, the internal thread 2 followed the form of the punch 3 is forged and formed.
