Description

本発明は、鋼管の切断工程で生じた管端バリを除去するのに好適な鋼管の管端バリ除去方法に関する。 The present invention relates to a pipe end burr removal method suitable for removing a pipe end burr generated in a cutting process of a steel pipe.

電縫鋼管などの鋼管を製造する際、走行する切断機をラインに配置し、オンラインにてそれを所定の長さに切断している（非特許文献１）。このような鋼管の切断工程では管端にバリが生じることが起こる。図８には電縫鋼管の切断工程で発生した管端バリ４の代表例を示した。このような管端バリがあると、横送り接管時、接管疵が生じてしまうため、管端バリを除去した後、鋼管を下流工程に供給するようにしている（図７参照）。   When manufacturing a steel pipe such as an electric resistance steel pipe, a traveling cutting machine is arranged in a line and is cut to a predetermined length online (Non-Patent Document 1). In such a steel pipe cutting process, burrs occur at the end of the pipe. FIG. 8 shows a typical example of the pipe end burr 4 generated in the cutting process of the ERW steel pipe. When such a pipe end burr exists, a pipe fistula is generated at the time of transverse feed contact pipe. Therefore, after removing the pipe end burr, the steel pipe is supplied to the downstream process (see FIG. 7).

その際、管端バリをオンラインで除去する処理時間（サイクルタイムという）がネックとならない場合は、プラズマカッター、チップソーなどでクロップ切断することで、管端バリ除去を行っていた。このような方法で管端バリ除去を行うと、鋼管の一部がクロップ切断されてしまうため、歩留りが悪化する。またクロップ切断するには処理時間がかかるので、切断工程でのサイクルタイムが短くなると、対応することができなくなる欠点もある。   At that time, if the processing time (referred to as cycle time) for removing the pipe end burrs online does not become a bottleneck, the pipe end burrs are removed by cropping with a plasma cutter, a tip saw, or the like. When the pipe end burr removal is performed by such a method, a part of the steel pipe is cropped, so that the yield is deteriorated. Further, since it takes a processing time to cut the crop, there is a disadvantage that it cannot be handled if the cycle time in the cutting process is shortened.

最近、電縫鋼管などの鋼管を製造するラインで、切断工程でのサイクルタイムが短くなることが頻繁にあり、これに対応することが要求されている。このため、具体的手段として、チップをスピンドルに装着した面取り機にて管端バリ除去を行うことを検討した。
日本鉄鋼協会編、「第３版 鉄鋼便覧 第III巻（２）」丸善株式会社、昭和55年11月20日発行、ｐ1056〜ｐ1057 Recently, in a line for producing a steel pipe such as an electric resistance steel pipe, the cycle time in the cutting process is frequently shortened, and it is required to cope with this. For this reason, as a specific means, it was examined to remove pipe end burrs with a chamfering machine in which a tip is mounted on a spindle.
Edited by Japan Iron and Steel Institute, “Third Edition Steel Handbook Volume III (2)” published by Maruzen Co., Ltd., November 20, 1980, p1056 to p1057

しかしながら、チップをスピンドルに装着した面取り機にて鋼管の管端バリ除去を行うと、チップの形状に起因する問題が発生する。以下、図を用いて、従来の面取り機により、鋼管の管端バリ除去を行う方法について説明する。図９は従来の鋼管の管端バリ除去方法の問題点を説明する平面図であり、図１０（ａ），（ｂ）は従来の面取り機に装着していた四角形状のチップ３Ａを示す正面図、側面図である。   However, if the end burr removal of the steel pipe is performed with a chamfering machine in which the tip is mounted on the spindle, a problem due to the shape of the tip occurs. Hereinafter, a method for removing pipe end burrs from a conventional chamfering machine will be described with reference to the drawings. FIG. 9 is a plan view for explaining the problems of the conventional method for removing the end burr of a steel pipe, and FIGS. 10 (a) and 10 (b) are front views showing a rectangular chip 3A mounted on a conventional chamfering machine. It is a figure and a side view.

従来の方法は、四角形状のチップ３Ａをスピンドル１に装着し、スピンドル１を回転させつつ管端に向かって前進させる過程で、鋼管の切断工程で生じた管端バリを除去するため、チップ３Ａで管端の外周部を切削していた。その際、前進側へ突出しているチップの角部が管端バリ４と接触し、そのときの衝撃でチップ欠けが発生しやすくなるという問題がある。   In the conventional method, the tip 3A is attached to the spindle 1 and the tip 3A is removed in the process of rotating the spindle 1 toward the end of the pipe while rotating the spindle 1 in the process of cutting the steel pipe. The outer peripheral part of the pipe end was cut. At that time, there is a problem that the corner of the tip protruding toward the forward side comes into contact with the tube end burr 4 and chipping is likely to occur due to the impact at that time.

またチップ３Ａの一辺に形成した直線形状の刃を面取り角αだけ傾ける必要があるため、管端の切削代を大きくせざるを得ず、切削負荷が大となる。したがって、チップの寿命が短く、バリ除去原単位の悪化や、チップ交換のためのライン停止による生産性の低下に結びつくという問題がある。
本発明は、上記従来技術の問題点を解消し、バリ除去原単位の悪化や生産性の低下を抑制しつつ、鋼管の切断工程で生じた管端バリをオンラインにて短時間でかつ確実に除去することができる鋼管の管端バリ除去方法を提供することを目的とする。 Further, since it is necessary to incline the linear blade formed on one side of the tip 3A by the chamfering angle α, the cutting allowance of the pipe end must be increased, and the cutting load increases. Therefore, there is a problem that the life of the chip is short, leading to deterioration of the burr removal basic unit and a decrease in productivity due to a line stop for chip replacement.
The present invention solves the above-mentioned problems of the prior art and suppresses the burr at the end of the pipe in a short time and reliably while suppressing the deterioration of the burr removal unit and the decrease in productivity. An object of the present invention is to provide a method for removing a pipe end burr from a steel pipe that can be removed.

本発明者は、鋭意検討し、四角形状のチップに代わり、前進側へ突出している角部がなく、管端バリ除去をチップで確実に行うために要する切削代を従来のよりも小さくすることができる形状のチップを用いることで、上記課題を効果的に解決できるとの知見を得た。
本発明は、以下のとおりである。 The present inventor has eagerly investigated that, in place of the square tip, there is no corner protruding to the forward side, and the cutting margin required to reliably remove the pipe end burr with the tip is made smaller than before. The knowledge that the said subject can be solved effectively by using the chip | tip of the shape which can be obtained was acquired.
The present invention is as follows.

１. 鋼管の製造ラインにおける切断工程で生じた管端バリをオンラインで除去する管端バリ除去方法であって、スピンドルの一端部に、前進側へ突出している角部がない丸形状のチップを着脱可能に、かつ、０度超９０度未満の切り屑逃がし角θを設けて装着し、前記スピンドルを回転させつつ管端に向かって前進させる過程で、鋼管の切断工程で生じた管端バリを前記チップで除去し、前記チップの刃で管端の外周部を切削速度112〜174m/minで切削することを特徴とする鋼管の管端バリ除去方法。
２. 前記スピンドルの送り速度を、前記チップの前進側縁が管端位置に達するまでの高速前進に対して、それ以降のバリ取り送り及び切削送りではそれよりも遅くすることを特徴とする１．に記載の鋼管の管端バリ除去方法。
1. A pipe end burr removal method that removes a pipe end burr generated in a cutting process in a steel pipe production line online, with a round tip without a corner protruding to the forward side at one end of a spindle. A pipe end burr generated in the cutting process of the steel pipe in the process of detachably mounting with a chip relief angle θ of more than 0 degrees and less than 90 degrees and advancing toward the pipe end while rotating the spindle. Is removed with the tip, and the outer peripheral portion of the tube end is cut at a cutting speed of 112 to 174 m / min with the blade of the tip.
2. The spindle feed speed is set to be slower than the high speed advance until the tip side edge of the tip reaches the pipe end position in the subsequent deburring feed and cutting feed. . A method for removing burrs at the end of a steel pipe as described in 1.

本発明によれば、四角形状のチップに代わり、前進側へ突出している角部がない丸形状のチップをスピンドルに装着し、スピンドルを回転させつつ管端に向かって前進させる過程で、鋼管の切断工程で生じた管端バリを除去するようにしたから、管端バリと接触する際の衝撃に強く、チップ欠けが発生し難い。また一辺に直線形状の刃を形成した四角形状のチップに代わり、管端の切削代を小さくすることができる丸形状のチップで、管端の外周部を切削するようにしたから、切削負荷が小となり、チップ交換までのチップ寿命を延ばすことができる。このため、バリ除去原単位の悪化や生産性の低下を抑制しつつ、鋼管の切断工程で生じた管端バリをオンラインにて短時間でかつ確実に除去することができる。   According to the present invention, instead of a square tip, a round tip without a corner protruding to the forward side is attached to the spindle, and in the process of rotating the spindle forward toward the end of the tube, Since the pipe end burr generated in the cutting process is removed, the chip is not easily chipped and resistant to an impact when contacting the pipe end burr. Also, instead of a square tip with a straight blade formed on one side, the tip of the tube end is cut with a round tip that can reduce the cutting allowance at the end of the tube, so the cutting load is reduced. The chip life can be extended until chip replacement. For this reason, the pipe end burr | flash produced in the cutting process of a steel pipe can be reliably removed on-line in a short time while suppressing the deterioration of the burr removal unit and the decrease in productivity.

まず、図を用い、本発明の方法に用いる一例の管端バリ除去装置について説明する。図１は本発明の方法に用いる一例の管端バリ除去装置を示す平面図であり、図２（ａ）は本発明の方法に用いる一例の管端バリ除去装置に用いたチップの形状を示す正面図、図２（ｂ）は側面図である。また図３には、本発明の方法に用いる一例の管端バリ除去装置の全体構成を示した。
この管端バリ除去装置を用い、丸形状のチップ３Ｂをスピンドル１に装着し、スピンドルを回転させつつ管端に向かって前進させる過程で、鋼管の切断工程で生じた管端バリを除去するようにし、同時にその縁に形成した刃で管端の外周部を切削するようにしたことが本発明の特徴である。 First, an example of a pipe end deburring device used in the method of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing an example of a tube end deburring device used in the method of the present invention, and FIG. 2A shows the shape of a tip used in the example of tube end deburring device used in the method of the present invention. FIG. 2B is a front view, and FIG. FIG. 3 shows an overall configuration of an example of a pipe end deburring device used in the method of the present invention.
Using this pipe end deburring device, the round tip 3B is mounted on the spindle 1 and the pipe end burr generated in the cutting process of the steel pipe is removed in the process of moving the spindle forward while rotating the spindle. At the same time, it is a feature of the present invention that the outer peripheral portion of the tube end is cut with a blade formed on the edge thereof.

この丸形状のチップ３Ｂには、図１、２に示したように、管端の外周部を切削することができる刃がその縁の全周に形成されてなる。このチップの材質は、従来の四角形状のチップ３Ａと同様、超鋼合金やセラミックスとすることができる。ただし本発明には、図２（ａ）、（ｂ）に示したが、孔付き円形状の面とチップ厚み方向の周面とが直交して構成される刃がチップ３Ｂの縁に形成されているものを示した。それ以外の構成は、従来の四角形状のチップ３Ａと同様である。   As shown in FIGS. 1 and 2, the round tip 3 </ b> B is formed with a blade capable of cutting the outer periphery of the tube end on the entire periphery of the edge. The material of this chip can be a super steel alloy or ceramics as in the conventional rectangular chip 3A. However, in the present invention, as shown in FIGS. 2 (a) and 2 (b), a blade is formed on the edge of the tip 3B so that the circular surface with a hole and the peripheral surface in the tip thickness direction are orthogonal to each other. Showed what it is. Other configurations are the same as those of the conventional rectangular chip 3A.

本発明の方法に用いる一例の管端バリ除去装置は、図３に示したように、スピンドル１を回転させる駆動モータなどの駆動源５と、該駆動源５に接続されたスピンドル１と、該スピンドル１を管端面に対して前進・後退させるスピンドル移動手段８と、スピンドル１の一端部に着脱可能なように装着された丸形状のチップ３Ｂと、管Ｗの切断工程で生じた管端バリを除去するため、管端をスピンドル１の一端部に対向させてスピンドルの軸芯と同軸に管端を保持するパイプクランプ６と、を具備している。７はクランプ用油圧ポンプユニットを示す。   As shown in FIG. 3, an example of a pipe end deburring device used in the method of the present invention includes a drive source 5 such as a drive motor that rotates the spindle 1, a spindle 1 connected to the drive source 5, Spindle moving means 8 for moving the spindle 1 forward and backward relative to the pipe end surface, a round tip 3B detachably attached to one end of the spindle 1, and pipe end burrs generated in the cutting process of the pipe W The pipe end 6 is provided with a pipe clamp 6 that holds the pipe end coaxially with the spindle axis with the pipe end facing one end of the spindle 1. Reference numeral 7 denotes a clamping hydraulic pump unit.

なお、丸形状のチップ３Ｂは、図１に示したように、アーム２のチップ取付部に着脱可能なように装着され、アーム２の基部がスピンドル１の一端部に固定されている。また上記したスピンドル移動手段は、スピンドル１を搭載したスライダ８と、それを前進・後退させるサーボモータ１１とされ、アーム２及びチップ３Ｂはパイプクランプ６の右側（図３）にある。９は管端バリ除去装置のベッドである。   As shown in FIG. 1, the round tip 3 </ b> B is detachably attached to the tip mounting portion of the arm 2, and the base portion of the arm 2 is fixed to one end portion of the spindle 1. The spindle moving means described above includes a slider 8 on which the spindle 1 is mounted and a servo motor 11 for moving the head forward and backward. The arm 2 and the tip 3B are on the right side (FIG. 3) of the pipe clamp 6. 9 is a bed of a pipe end deburring device.

この管端バリ除去装置によれば、スピンドル１を回転させつつ前進させる過程で、鋼管の切断工程で生じた管端バリを除去するようにし、同時に丸形状のチップ３Ｂの縁に形成した刃で管端の外周部を切削することができる。その際、図４に示すように、切り屑逃がし角θ（θ＜９０度）を設けるのが好ましい。またスピンドルの送り速度を、チップの前進側縁が管端位置に達するまでの高速前進に対して、それ以降のバリ取り送り及び切削送りではそれよりも遅くすることが、バリ除去原単位の悪化や生産性の低下を抑制しつつ、鋼管の切断工程で生じた管端バリをオンラインで短時間でかつ確実に除去することができるので好ましい。図４中、ａ：待機位置からｂ：早送り完了位置までが高速前進に対応し、ｂ以降、ｃ：バリ取り切削完了位置、ｄ：管端接触位置を経てｅ：切削送り完了位置までがバリ取り送り及び切削送りに対応する。これらの位置、各区間のスピンドルの送り速度、スピンドルの回転速度などの条件は、面取り機の制御盤１０に設定され、管端バリ除去を行う際に実行される。   According to this pipe end burr removing device, the pipe end burr generated in the cutting process of the steel pipe is removed in the process of rotating the spindle 1 forward, and at the same time, the blade formed on the edge of the round tip 3B. The outer periphery of the tube end can be cut. At that time, as shown in FIG. 4, it is preferable to provide a chip relief angle θ (θ <90 degrees). In addition, it is possible to make the spindle feed speed slower than the high speed advance until the tip side edge of the tip reaches the pipe end position. In addition, it is preferable because pipe end burrs generated in the steel pipe cutting process can be reliably removed online in a short time while suppressing a decrease in productivity. In FIG. 4, a: From the standby position to b: rapid feed completion position corresponds to high-speed forward movement, and after b, c: deburring cutting completion position, d: pipe end contact position, and e: cutting feed completion position. Corresponds to feed and cutting feed. Conditions such as these positions, spindle feed speed of each section, spindle rotation speed, etc. are set in the control panel 10 of the chamfering machine and are executed when pipe end burr removal is performed.

ここで、管端バリ除去を確実に行うために必要な管端の切削代ｔ１は、図５に従来の場合と対比して示したように、丸形状のチップの方が四角形状のチップに比べて小さくすることができる。また図６には、管端切削時の管端バリ４の形状を、四角形状のチップを用いた従来の場合と、丸形状のチップをスピンドルに装着した場合とで対比して示した。
このように本発明によれば、丸形状のチップをスピンドル１に装着し、スピンドルを回転させつつ管端に向かって前進させる過程で、鋼管の切断工程で生じた管端バリを除去するようにし、同時にその縁に形成した刃で管端の外周部を切削するようにしたから、前述した作用・効果を発揮することができる。前述した作用・効果を発揮することができるチップは、丸（円形）のものが製作が容易であるが（図１、図２（ａ）参照）、楕円形のようなチップもＮＣ制御装置を具備した加工機械によれば容易に製作することができる。このような楕円形のチップも、円形のチップと同様、前進側へ突出している角部がない形状でかつ管端バリ除去を確実に行うために必要な管端の切削代ｔ１を、従来の四角形状のチップに比べて小さくすることができるから、前述した作用・効果を発揮することができるものである。 Here, as shown in FIG. 5 in comparison with the conventional case, the cutting allowance t1 of the pipe end necessary for reliably removing the pipe end burr is changed from a round tip to a square tip. It can be made smaller. Further, FIG. 6 shows the shape of the tube end burr 4 at the time of cutting the tube end in comparison with a conventional case using a square tip and a case where a round tip is mounted on a spindle.
As described above, according to the present invention, a round tip is attached to the spindle 1, and the pipe end burr generated in the cutting process of the steel pipe is removed in the process of moving the spindle forward while moving the spindle. At the same time, since the outer peripheral portion of the tube end is cut with the blade formed on the edge, the above-described actions and effects can be exhibited. Chips that can exhibit the functions and effects described above are easy to manufacture with round (circular) chips (see FIGS. 1 and 2 (a)). According to the processing machine provided, it can be easily manufactured. Similar to the circular tip, such an elliptic tip has a shape with no corner protruding to the forward side, and the tube end cutting margin t1 necessary for reliably removing the tube end burr is reduced by the conventional tip. Since it can be made smaller than a square chip, the above-described functions and effects can be exhibited.

鋼管の外径：76.3〜114.3mm、肉厚：1.8〜8.4mmの鋼管（STKM13B相当）を製造する電縫鋼管の製造ラインに本発明を適用した。その際、チップとして、従来の四角形状のチップに代わり、前進側へ突出している角部がなく、管端バリ除去をチップで確実に行うために要する管端の切削代を従来のよりも小さくすることができる丸形状のチップを用いた。丸形状のチップの外径を20mm、チップ厚みを７mmとした。その他の管端バリの除去条件と所要時間を合わせて表１（鋼管径＝φ88ｍｍ）に示した。なおバリ取り送りとは、管端の外周部を切削する前に管端バリを除去する送りをいい、切削送りとは、管端の外周部を切削することで、その前のバリ取り送りで除去できなかった管端バリを除去する送りをいう。   The present invention was applied to an ERW steel pipe production line for producing a steel pipe (equivalent to STKM13B) having an outer diameter of 76.3 to 114.3 mm and a wall thickness of 1.8 to 8.4 mm. At that time, instead of the conventional rectangular tip, there is no corner protruding to the forward side, and the cutting margin of the tube end required to reliably remove the tube end burr with the tip is smaller than the conventional tip. A round chip that can be used was used. The outer diameter of the round chip was 20 mm, and the chip thickness was 7 mm. The other pipe end burr removal conditions and required time are shown in Table 1 (steel pipe diameter = 88 mm). Deburring feed refers to feed that removes pipe end burrs before cutting the outer periphery of the tube end. Cutting feed refers to cutting the outer peripheral portion of the pipe end, This is a feed that removes the burr at the end of the tube that could not be removed.

表１に示した結果から、正味切削時間を管端当たり1.81秒という短時間で電縫鋼管の切断工程で生じた管端バリを確実に除去することができた。また本発明を電縫鋼管の製造ラインに適用した結果、四角形状のチップをスピンドルに装着した従来の場合に比べ、チップ寿命を４倍以上に延ばすことができ、バリ除去原単位を1/4以下にでき、さらにバリ除去工程に影響されることなく生産性も維持できた。この実施例では本発明を電縫鋼管の製造ラインに適用したとして説明したが、シームレス鋼管などの鋼管の製造ラインにも同様に適用することができる。また銅製などの非鉄丸パイプや樹脂製の非鉄丸パイプなどを製造する際にもその切断工程に続き、バリ除去工程に本発明を適用することができる（図７参照）。   From the results shown in Table 1, the pipe end burrs generated in the cutting process of the ERW steel pipe could be reliably removed in a short net cutting time of 1.81 seconds per pipe end. In addition, as a result of applying the present invention to an ERW steel pipe production line, the tip life can be extended more than four times compared to the conventional case where a square tip is mounted on the spindle, and the deburring unit is reduced to 1/4. The productivity could also be maintained without being affected by the deburring process. In this embodiment, the present invention is described as being applied to a production line for ERW steel pipes, but the present invention can also be applied to a production line for steel pipes such as seamless steel pipes. In addition, when manufacturing non-ferrous round pipes made of copper, non-ferrous round pipes made of resin, etc., the present invention can be applied to the burr removing process following the cutting process (see FIG. 7).
