Description

本発明は、鋼管のねじ切り方法及び装置に関する。さらに詳しくは、管を固定し、管端に雄ねじを形成する回転刃物装置を用いる鋼管のねじ切り方法及び装置に関する。   The present invention relates to a steel pipe threading method and apparatus. More specifically, the present invention relates to a steel pipe threading method and apparatus using a rotary blade device for fixing a pipe and forming a male screw at a pipe end.

従来、一般に、鋼管のねじ切りは、管を固定しねじ切削用刃形を装着した刃物回転ねじ切り機を回転前進させる技術と、管側を回転し複数回刃物を往復させてねじを形成する手段とがある。   Conventionally, in general, thread cutting of a steel pipe is a technique of rotating and moving a blade rotating thread cutting machine which fixes a pipe and is equipped with a thread cutting blade shape, and means for rotating a pipe side and reciprocating a blade multiple times to form a screw. There is.

ＮＣ旋盤を用いて管側を回転しながら粗加刃物と仕上げ加工刃物によるねじ切りを同時に行う技術がある（例えば、特許文献１参照。）。   There is a technique of simultaneously performing thread cutting with a rough cutting tool and a finishing tool while rotating the tube side using an NC lathe (see, for example, Patent Document 1).

その技術では２つの刃部を備えた仕上げ加工刃物を用いるので刃部に作用する切削負荷が小さくなって仕上げ加工刃物の摩耗を抑制することができるとしている。   According to the technique, since a finishing tool with two blades is used, the cutting load acting on the blade is reduced, and wear of the finishing tool can be suppressed.

一方、刃物回転ねじ切り機は、管端ねじのテーパを先行加工するターニング刃物を円周上に３〜６ヶ所備え、その後方にねじを順次切削加工するチェザーを円周上３ヶ所に設けた切削ヘッドを用いる。この切削ヘッドは管端周囲に沿って旋回しながらねじピッチと同一のピッチで前進し、ねじ加工を行う。チェザーはねじを順次形成する刃形を有し、例えば９回の切削により１個のねじ山を形成する。   On the other hand, the cutter rotary threading machine is provided with 3 to 6 turning cutters on the circumference that preliminarily process the taper of the tube end screw, and a cutting machine that is provided with three chesers that sequentially cut the screws behind it. Use the head. This cutting head moves forward along the periphery of the pipe end and advances at the same pitch as the screw pitch, and performs screw machining. The chaser has a blade shape for sequentially forming screws, and for example, one thread is formed by cutting nine times.

この切削ヘッドは、ねじ切削のための大きな回転力及び管軸方向の大きな推力を受ける。これらの大きな作用力に対して十分な剛性を備える必要がある。そしてこの剛性がねじ精度を大きく支配する。従って、剛性を高める工夫が種々施されている。   This cutting head receives a large rotational force for thread cutting and a large thrust in the tube axis direction. It is necessary to provide sufficient rigidity for these large acting forces. And this rigidity greatly dominates the screw accuracy. Therefore, various devices for increasing the rigidity are applied.

本発明者は、刃物回転ねじ切り方法及びその装置に関する技術であって、ねじの精度向上を図るため推力の大きさの変化に着目した。
特開２０００−１１７５４２号公報（第２−３頁、図１） The inventor of the present invention is a technique related to a blade rotating thread cutting method and an apparatus therefor, and pays attention to a change in the magnitude of thrust in order to improve the accuracy of the screw.
JP 2000-117542 A (page 2-3, FIG. 1)

本発明はシームレス鋼管の管端にねじ切り加工を行う刃物回転式ねじ切り装置を用いて、より精度の高いねじ切りを行う技術を提供することを目的とするものである。   An object of the present invention is to provide a technique for performing higher-accuracy thread cutting using a rotary cutter thread cutting device that performs thread cutting on a pipe end of a seamless steel pipe.

本発明は、上記問題点を解決するためになされたもので、次の技術手段を講じたことを特徴とする鋼管のねじ切り方法及び装置である。すなわち、本発明は、シームレス鋼管の管端に１回のチャッキングと１工程でターニング加工によりテーパ部を形成し、チェザーによるねじ切り加工を追行させるねじ切り方法において、ターニング加工による軸方向荷重が開放した後、チェザーによるねじ切り加工を施工することを特徴とする鋼管のねじ切り方法である。   The present invention has been made in order to solve the above-mentioned problems, and is a method and apparatus for threading a steel pipe, characterized by taking the following technical means. That is, the present invention is a threading method in which a tapered portion is formed at the end of a seamless steel pipe by one chucking and turning process in one step, and the threading process by a chaser is followed. Then, a threading method for a steel pipe, characterized in that a threading process is performed by a chaser.

本発明はターニング加工とねじ切り加工が重複することによって大きな軸方向荷重（推力）を必要とし、この大きな軸方向荷重（推力）による刃物装置の歪がねじ精度の低下を来ることを知見し、この知見に基いてなされたものである。すなわち、ターニング加工による軸方向荷重が開放した後、チェザーによるねじ切り加工を施工し、ターニング加工荷重とねじ切り加工荷重とを分離することによって、軸方向荷重（推力）の最大値を減少させ、ねじ加工精度を向上させようとするものである。   The present invention requires that a large axial load (thrust) is required due to the overlap of turning and threading, and the distortion of the blade device due to this large axial load (thrust) results in a decrease in screw accuracy. It was made based on knowledge. In other words, after the axial load due to turning is released, threading is performed by a chaser, and the maximum value of axial load (thrust) is reduced by separating the turning load and the threading load, thereby screwing It is intended to improve accuracy.

上記本発明方法を好適に実施することができる本発明の装置は、シームレス鋼管の管端ねじ切りを行う回転ねじ切り装置において、ターニング刃物とチェザーの先頭刃物との管軸方向離隔距離を管のターニング加工される管軸方向長より大きくしたことを特徴とする鋼管のねじ切り装置である。ターニング刃物がターニング加工を終了した後、チェザーによるねじ切り加工を行うので、この装置によれば、ターニング加工時の軸方向荷重とねじ切り時の軸方向荷重とを確実に分離することができる。   The apparatus of the present invention capable of suitably carrying out the above-described method of the present invention is a rotary threading device for threading a seamless steel pipe at the end of the tube. The steel pipe threading device is characterized in that it is larger than the length in the pipe axial direction. Since the threading process is performed by the chaser after the turning tool finishes the turning process, according to this apparatus, the axial load at the time of turning process and the axial load at the time of threading process can be reliably separated.

本発明によれば、シームレス鋼管の管端ねじ切り切削加工において、軸方向荷重（推力）のピークを抑えることができ、精度のよいねじを形成することが可能となった。   According to the present invention, it is possible to suppress the peak of the axial load (thrust) in tube end thread cutting of a seamless steel pipe, and to form a highly accurate screw.

以下図面を参照して本発明の実施の形態を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は本発明の実施例の鋼管のねじ切り装置１０の主要部を示す縦断面図である。   FIG. 1 is a longitudinal sectional view showing a main part of a steel pipe threading device 10 according to an embodiment of the present invention.

ねじ切り装置１０は回転ヘッド１１とこれを回転させ軸方向荷重（推力）を支持する部分とから成っている。回転ヘッドにはチェザーブロック１２が設けられている。チェザーブロック１２は継目無鋼管１００の管端１０１にねじを切削加工するターニング刃物２０とチェザー３０を内周側に備えている。また、円周方向に複数分割され、外周側は円錐テーパを形成し、テーパウエジ１３内に保持されている。チェザーブロック１２は回転しながら鋼管外径方向に徐々に開いて管端ねじを形成する。   The thread cutting device 10 includes a rotary head 11 and a portion that rotates the head 11 and supports an axial load (thrust). A chaser block 12 is provided on the rotary head. The chaser block 12 includes a turning blade 20 for cutting a screw on the pipe end 101 of the seamless steel pipe 100 and a chaser 30 on the inner peripheral side. Further, it is divided into a plurality of parts in the circumferential direction, and the outer peripheral side forms a conical taper and is held in the taper wedge 13. While rotating, the chaser block 12 gradually opens in the outer diameter direction of the steel pipe to form a pipe end screw.

回転ヘッド１１は、図示省略した回転駆動装置により回転軸（主軸）４０を介して回転を与えられ、伝達軸５２を介して回転及び軸方向荷重（推力）４２を与えられる。回転軸（主軸）４０はフレーム１４に軸受を介して支持されており、回転力４１を伝達する。   The rotary head 11 is rotated by a rotary drive device (not shown) via a rotary shaft (main shaft) 40, and is given a rotation and an axial load (thrust) 42 via a transmission shaft 52. The rotation shaft (main shaft) 40 is supported on the frame 14 via a bearing, and transmits a rotational force 41.

伝達軸５２はアダプタチューブ５０上に軸受５１を介して支持され、回転すると共に回転ヘッド１１の軸方向への位置制御のために軸方向荷重を伝達する。アダプタチューブ５０は非回転で、ねじ切り装置本体１０に対して図の向って左側へ動作する。鋼管１００を固定した後、ねじ切り装置１０を回転させながら図の向かって右方へ前進させると、まずターニング刃物２０が管端１０１を切削して管端にテーパ部を形成し、次いでチェザー３０がこのテーパ部にねじを切削形成する。   The transmission shaft 52 is supported on the adapter tube 50 via a bearing 51 and rotates and transmits an axial load for position control of the rotary head 11 in the axial direction. The adapter tube 50 is non-rotating and moves to the left in the direction of the drawing with respect to the threading device body 10. After the steel pipe 100 is fixed, when the threading device 10 is rotated and advanced to the right as viewed in the figure, the turning blade 20 first cuts the pipe end 101 to form a tapered portion at the pipe end, and then the chaser 30 A screw is cut and formed in the tapered portion.

図２はチェザーブロック１２のターニング刃物２０とチェザー３０の取付部を示す側面図である。ターニング刃物２０は取付部２１を固定ボルト２２等によりチェザーブロック１２に固定されており、チェザー３０は取付部２１の固定ボルト２２等によりチェザーブロック１２に固定されている。ターニング刃物２０の切削刃とチェザー３０の先頭側の刃との間隔１５が示されている。   FIG. 2 is a side view showing a mounting portion between the turning blade 20 and the chaser 30 of the chaser block 12. The turning blade 20 has a mounting portion 21 fixed to the tether block 12 by a fixing bolt 22 or the like, and the chaser 30 is fixed to the tether block 12 by a fixing bolt 22 or the like of the mounting portion 21. A distance 15 between the cutting blade of the turning blade 20 and the leading blade of the chaser 30 is shown.

図３は鋼管１００の管端部１０１にねじ切り加工を行う工程を模式的に示した説明図である。鋼管１００を固定してチェザーブロックを回転前進させると、ターニング刃物２０の切削刃２３は切削線２４に沿って前進切削し、軸方向長１０３のテーパ部を形成する。次いでチェザー３０が前進し軸方向長１０３のテーパ部に完全ねじ山のねじを切削形成し、さらに軸方向長１０４の不完全ねじ山を切削形成し、合計軸方向長１０２のねじを形成する。   FIG. 3 is an explanatory view schematically showing a process of threading the pipe end portion 101 of the steel pipe 100. When the steel pipe 100 is fixed and the chaser block is rotated and advanced, the cutting blade 23 of the turning blade 20 advances and cuts along the cutting line 24 to form a taper portion having an axial length 103. The chaser 30 then advances to cut and form a complete thread on the taper of axial length 103, and further cut and form an incomplete thread of axial length 104 to form a total axial length 102 thread.

本発明は、このターニング刃物２０の切削工程とチェザー３０の切削工程とが重複しないようにするものである。すなわちターニング刃物２０の切削刃２３とチェザー３０の先頭刃物３３との管軸方向離隔距離１５を前記のターニング刃物２０の形成したテーパ部の管軸方向長１０３より大きくしておく。   The present invention prevents the cutting process of the turning blade 20 and the cutting process of the chaser 30 from overlapping. That is, the separation distance 15 in the tube axis direction between the cutting blade 23 of the turning blade 20 and the leading blade 33 of the chaser 30 is set larger than the tube axis direction length 103 of the tapered portion formed by the turning blade 20.

このことによって、ターニング刃物２０の切削工程とチェザー３０の切削工程が重複することがなく、両者の軸方向荷重（推力）が重複することがない。   Thereby, the cutting process of the turning blade 20 and the cutting process of the chaser 30 do not overlap, and the axial loads (thrust forces) of both do not overlap.

次に実例をあげて説明する。   Next, an example will be described.

中径シームレス工場において、１３−３／８インチねじ切り装置におけるねじ切り時の推力（軸方向荷重）の時間推移を示した測定例を図４に示した。図２において、横軸は測定時刻を示し、縦軸は推力（軸方向荷重）の大きさを示している。推力（軸方向荷重）はマイナス値で示されている。   FIG. 4 shows a measurement example showing a time transition of thrust (axial load) at the time of threading in a 13-3 / 8 inch threading device in a medium-diameter seamless factory. In FIG. 2, the horizontal axis indicates the measurement time, and the vertical axis indicates the magnitude of the thrust (axial load). The thrust (axial load) is shown as a negative value.

従来の通常切削では実線６１で示すように−２２４．４１ｋｇｆ（−２．２ｋＮ）のピークを示している。これを、切削ヘッド１１からチェザーを取り外して試験を行うと、曲線６２で示すように−１６３．５７ｋｇｆ（−１．６ｋＮ）をピークとしてその後、順次減少する曲線となった。また、ターニング加工を施した後チェザー加工のみを行ったときは、曲線６３で示すように、ピーク値として−１５４．０８ｋｇｆ（−１．５ｋＮ）を示した後減少する推移となった。ここで曲線６１は曲線６２と６３とを重畳したものであることが明らかになった。   In the conventional normal cutting, as shown by the solid line 61, a peak of -224.41 kgf (-2.2 kN) is shown. When the test was performed with the chaser removed from the cutting head 11, as shown by the curve 62, the peak was −163.57 kgf (−1.6 kN), and then the curve gradually decreased. Further, when only the chaser process was performed after the turning process, as shown by the curve 63, the peak value showed −154.08 kgf (−1.5 kN) and then decreased. Here, it is clear that the curve 61 is obtained by superimposing the curves 62 and 63.

図５は従来と本発明の、ターニング加工とねじ切り加工のタイミングを変更することによる効果を示す模式的なグラフである。図５（ａ）に示すように、従来の推力（軸方向荷重）のピークが２２４であったものが、本発明では図５（ｂ）に示すように、１６４と約３０％低減した。   FIG. 5 is a schematic graph showing the effect of changing the timing of the turning process and the threading process according to the prior art and the present invention. As shown in FIG. 5 (a), the peak of the conventional thrust (axial load) was 224, but in the present invention, as shown in FIG.
