本考案はねじを刻設した後にキー溝加工する際
に発生するバリ返りを除去するために用いるねじ
部バリ取り用具に関するものである。[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a thread deburring tool used to remove burrs that occur when keyway machining is performed after a thread has been carved.
（従来の技術）
第６図および第７図に示すように、部材ａにね
じ加工してねじ部ｂを刻設したのち、キー溝加工
してキー溝部ｃを形成すると、ねじ山ｄから谷部
ｅにかけて返りバリｆが起生する。(Prior art) As shown in FIGS. 6 and 7, when a member a is threaded to form a threaded portion b and then keywayed to form a keyway portion c, a valley is formed from the threaded thread d. Return burrs f occur at part e.
このような返りバリｆを除去するため、従来は
キー溝加工した後に、ダイスを通してねじ部ｂの
返りバリｆを除去した。 In order to remove such a return burr f, conventionally, after keyway machining, the return burr f of the threaded portion b was removed through a die.

には不適である。 The die disclosed in Japanese Utility Model Application Publication No. 59-24218 is a die for regenerating thread threads, in which a halved die provided with a spiral thread blade is set in a socket and rotated to regenerate thread threads. The die must have the same thread diameter and pitch as the thread to be reclaimed, and the die must be rotated in the opposite direction to remove it after the reclaiming process. It is unsuitable for deburring the key grooves of parts.
