Abstract

PURPOSE:To obtain a tooth thread rolling flat die which has reduced a pressure generating load and is capable of balancing thickness of a tooth pressure generated product, by gradually increasing the tooth height of a gnawed tooth group formed on the die toward a finshied tooth from the gnawed end side. CONSTITUTION:A flat die 10 is formed by arraying plural gnawed teeth 11, finished teeth 12, and escape teeth in the lengthwise direction. A straight line connecting each bottom tooth of the gnawed tooth 11 and the finished tooth 12 is formed in parallel with a bottom surface 15. Each tooth height GH of the gnawed tooth 11 group is inclined so that it gradually decreases toward the initial gnawed end side from the finished tooth 12 side. Also, a pair PR, PF of single tooth surface pitches between adjacent gnawed teeth are PR-PF, and are formed so that its mean value becomes equal to a standard pitch PO of the finished tooth 12, and thread rolling allowance is given in the tooth height direction and the tooth thickness direction. In this way, thickness of a leading side tooth surface and a trailing side tooth surface of a tooth form in a generated product is equalized as much as possible.
