【発明の詳細な説明】 A、産業上の利用分野 本発明は小径長尺管の内面ビード研削装置に関する。[Detailed description of the invention] A. Industrial application field The present invention relates to an internal bead grinding device for small diameter long tubes.
B、従来の技術
従来、長尺物(6m前後)で小径管(60゜5′以下)
の内面ビード除去作業は、軸先端の円盤砥石を回転させ
て行われていた。しかして、軸は細い剛性軸の複数本が
接続端の互いに係合する凹凸にビンを貫通させて接続さ
れたものであった。B. Conventional technology Conventionally, long objects (approximately 6 m) and small diameter pipes (60° 5' or less)
The inner bead removal work was done by rotating a disc grindstone at the tip of the shaft. Thus, the shafts were formed by connecting a plurality of thin rigid shafts by passing the bottles through the recesses and recesses that engaged with each other at the connecting ends.
C1発明が解決しようとする課題
ところが、軸の接続部が弱いため、砥石のビードへの押
圧力が小さく、従って、砥石がビードから逃げてビード
処理が不完全であった。そのため、何度も同じ個所を研
削しなければならず、非常に非常に能率が悪かった。し
かも、特に外径34.4’(内径26.6’ )以下の
ものについてはビード除去作業は至難の技であった。The problem to be solved by the invention C1 is that since the connecting portion of the shaft is weak, the pressing force of the grindstone against the bead is small, and therefore the grindstone escapes from the bead, resulting in incomplete bead processing. As a result, the same location had to be ground over and over again, which was extremely inefficient. Moreover, it is extremely difficult to remove the bead especially when the outer diameter is less than 34.4' (inner diameter 26.6').

Therefore, commercially available very thin materials such as wires can be used, which allows the use of very thin protective tubes. Therefore, it has become possible to perform internal bead grinding of small diameter pipes of 60.5' or less. Moreover, since the intermediate shaft and protective tube can be made longer, it is possible to grind the long tube from one side of both end faces, which makes it possible to greatly improve efficiency and improve quality stability. In addition, we have provided a whetstone holder, so by adjusting the length of the legs,
The grinding allowance can be adjusted according to the condition of the inner bead, and
