Description
本発明は、管の切断線を罫書く罫書き治具及び罫書き方法に関するものである。 The present invention relates to a scoring jig and scoring method for scoring a cutting line of a pipe.
工場等の既設配管を改造工事等行う場合、管の切断が必要となる。
改造工事等における既設管の基準点での切断や作業場での配管加工製作時には、その切断のために管を罫書かなければ正確な切断は困難になる。
中口径の管の罫書き方法としては、厚紙やプラスチックの薄板で作った定規（型紙）を用いて管の周方向へ密着胴巻きにして、それを一周させてその定規を用いて線を引いていた。
When remodeling existing pipes in factories, etc., it is necessary to cut the pipes.
When cutting existing pipes at the reference point in remodeling work or manufacturing pipes in the workplace, accurate cutting becomes difficult unless the pipes are marked for cutting.
As a ruler for medium-diameter pipes, a ruler (pattern paper) made of cardboard or plastic thin plate is used to wind tightly around the pipe in the circumferential direction, and the line is drawn using the ruler. It was.
他には、例えば特許文献１に記載のような罫書き治具を用い、管の端面から等距離の位置に罫書き線を引くこともある。 In addition, for example, a ruled line jig as described in Patent Document 1 may be used to draw a ruled line at a position equidistant from the end face of the tube.
ここで、３００Ａ程度の口径の管を罫書くとき、厚紙定規を用いる罫書き方法の場合では１メートル程度の厚紙定規で足りる。 Here, when ruled a pipe having a diameter of about 300A, a thick paper ruler of about 1 meter is sufficient in the case of a ruled writing method using a cardboard ruler.
しかし、大口径配管の場合は、相当の型紙の長さ（１０００Ａでは、３．１４メートル以上）が必要になるので、正確な罫書きが難しかった。
また、他の方法としては計算により点を付していき、それを直線で結んで罫書き線を引く方法もあるが、多くの点を算出してプロットしなければいけないので、大変に手間が掛かる。
However, in the case of a large-diameter pipe, since a considerable length of the paper pattern (3.14 meters or more at 1000 A) is required, accurate scoring is difficult.
In addition, as another method, there is a method of attaching points by calculation and connecting them with straight lines to draw ruled lines, but since many points must be calculated and plotted, it is very troublesome. It takes.
さらに、既設管や管材料の両端が切断された物を罫書く場合は、工場で正確な基準を元に罫書くことよりも難しくなる。そして、その罫書き線が正確に引かれたか、切断後その断面が正確かを確認することが困難であるので、管同士を接続する面合せの際に切削調整に手間がかかった。 Furthermore, when marking an existing pipe or pipe material with both ends cut, it becomes more difficult than marking at the factory based on accurate standards. And since it is difficult to confirm whether the scribe line is drawn accurately or the cross section is accurate after cutting, it takes time and effort to adjust the cutting when the pipes are connected to each other.
そこで、本発明の目的とするところは、大口径の管や既設管であっても容易かつ正確に罫書くことができる罫書き治具及び罫書き方法を提供することにある。 Accordingly, an object of the present invention is to provide a scoring jig and a scoring method capable of easily and accurately scoring even a large-diameter pipe or an existing pipe.

Such a light emitting unit 20 is available as a commercial product.
このように構成された罫書き治具１を使用した罫書き方法にについて、図２を参照しながら説明する。
まずは図２のαについて説明する。αは管Ｋの軸に対して垂直な罫書き線を引く場合である。ここでは横断切りと読んでいる。
A scoring method using the scoring jig 1 configured as described above will be described with reference to FIG.
First, α in FIG. 2 will be described. α is a case where a ruled line perpendicular to the axis of the tube K is drawn. I read here as cross-cutting.
まず、管Ｋの頂点を付す。つまり左右方向の水準器１５を合わせて、その位置において光源の直下位置が管Ｋの頂点である。ここに点を付す（状態Ａ）。これを基準点とする。
それと同時に、光源が下方に対し左右方向に伸びる線状に照射しているので、状態Ａでレーザー光を照射させつつ、その照射線上にペン等を用いて一つ又は複数の点を付す。
First, the apex of the tube K is given. In other words, the level immediately below the light source is the apex of the tube K at the position of the level 15 in the left-right direction. A dot is added here (state A). This is the reference point.
At the same time, since the light source irradiates in a line extending in the left-right direction with respect to the lower side, one or a plurality of points are attached to the irradiation line using a pen or the like while irradiating the laser light in the state A.
次に、罫書き治具１を管Ｋに沿わせて左右方向に移動させ状態Ｂのようにし、先に付した点を照射線が通るように罫書き治具１の位置を微調整する。
そして、このとき照射線上に複数の点を付す。
状態Ｃや状態Ｄとなるように順に罫書き治具１を管Ｋに沿わせて下方に移動させつつこれを繰り返し、付した点を直線で結ぶことで罫書き線を引いていく。
Next, the scoring jig 1 is moved in the left-right direction along the tube K so as to be in the state B, and the position of the scribing jig 1 is finely adjusted so that the irradiation line passes through the previously attached point.
At this time, a plurality of points are added on the irradiation line.
This is repeated while moving the scoring jig 1 along the tube K in order so as to be in the state C and the state D, and the scoring line is drawn by connecting the attached points with straight lines.
罫書き治具１の管Ｋに対して右方向に１８０度分行うとともに、左方向にも１８０度分行うと、管Ｋの下端位置において両方からの罫書き線が一致する。 If it is performed 180 degrees in the right direction and 180 degrees in the left direction with respect to the tube K of the ruler jig 1, the ruled lines from both coincide at the lower end position of the tube K.
この方法は、図２のβのように、罫書き治具１を９０度回転させた状態でも行うことができる。このβの場合には、後壁１３ｂに取り付けられた基準点針１４で点を付してもよい。
αとβのどちらの向きで行うかは、罫書き治具１の大きさと管Ｋの径との関係でやりやすいほうを選べば良い。
This method can also be performed in a state where the ruler jig 1 is rotated 90 degrees as indicated by β in FIG. In the case of β, a point may be given by the reference point needle 14 attached to the rear wall 13b.
The direction of α or β may be selected according to the relationship between the size of the scoring jig 1 and the diameter of the tube K.
次に、図２のγのように、管Ｋの軸に対して斜め（直角以外）に罫書く場合を説明する。
まず、頂点を付すとともに、罫書き線上に存在する点を算出して管Ｋに付す。
そして、レーザー光の照射角度を所望の角度に変更し、発光部２０から照射される線状のレーザー光が頂点と算出点とを通るように、罫書き治具１を配置する（状態Ａ）。
この状態で、照射線上にペン等を用いて複数の点を付す。
Next, a description will be given of a case in which the ruled lines are written obliquely (other than at right angles) with respect to the axis of the tube K as indicated by γ in FIG.
First, a vertex is attached, and points existing on the ruled line are calculated and attached to the tube K.
Then, the laser beam irradiation angle is changed to a desired angle, and the ruler jig 1 is arranged so that the linear laser beam irradiated from the light emitting unit 20 passes through the apex and the calculation point (state A). .
In this state, a plurality of points are attached on the irradiation line using a pen or the like.
次に、罫書き治具１を管Ｋに沿わせて前方かつ左右方向に移動させ状態Ｂのようにし、先に付した点を照射線が通るように罫書き治具１の位置を微調整する。
そして、照射線上に複数の点を付して、罫書き線を延長する。
これを左右両方向行い、斜切りと呼ばれる罫書き線を引く。
Next, the scoring jig 1 is moved forward and left and right along the tube K so as to be in the state B, and the position of the scribing jig 1 is finely adjusted so that the irradiation line passes through the previously attached point. To do.
Then, a plurality of points are added on the irradiation line to extend the ruled line.
This is done in both the left and right directions, and a ruled line called oblique cutting is drawn.
以上のように構成された罫書き治具１及び罫書き方法によれば、天板１１から下方に立設する四つの脚部１２を備え、脚部１２下端はそれぞれ、天板１１と平行な同一平面内に存在するので、管Ｋの周面であっても安定して罫書き治具１を配置することができる。
そして、光源が天板１１よりも前方に突出し、少なくとも下方に対し線状にレーザー光を照射可能な発光部２０を備えるので、管Ｋの周面に照射されたレーザー光上に罫書き線を引くことができる。
また、罫書き治具１を平行移動させることで罫書き線を延長することができるので、大口径の管Ｋや既設管Ｋであっても容易かつ正確に罫書くことが可能である。
According to the scoring jig 1 and scoring method configured as described above, four leg portions 12 are provided to stand downward from the top plate 11, and the lower ends of the leg portions 12 are parallel to the top plate 11. Since it exists in the same plane, even if it is the surrounding surface of the pipe | tube K, the scribing jig 1 can be arrange | positioned stably.
Since the light source projects forward from the top plate 11 and includes the light emitting unit 20 capable of irradiating laser light linearly at least downward, a ruled line is formed on the laser light irradiated on the peripheral surface of the tube K. Can be drawn.
Further, since the scribe line can be extended by moving the scribe tool 1 in parallel, the scribe line can be drawn easily and accurately even with a large-diameter pipe K or an existing pipe K.
また、発光部２０から照射される線状のレーザー光の照射角度を変更可能なので、管Ｋの軸に対して傾斜させて罫書くこともできる。 In addition, since the irradiation angle of the linear laser light emitted from the light emitting unit 20 can be changed, it is possible to make a ruled line while being inclined with respect to the axis of the tube K.
なお、本実施形態において、発光部２０から照射される線状のレーザー光の照射角度を変更可能であるとしたが、これに限られるものではなく、固定されていても横断切りの罫書きは可能である。 In the present embodiment, the irradiation angle of the linear laser light emitted from the light emitting unit 20 can be changed. However, the present invention is not limited to this, and the cross-cut rules are not limited to this. Is possible.
また、発光部２０から照射される線状のレーザー光は、前後、左右、上下の三方向であるとしたが、これに限られるものではなく、少なくとも下方に対し左右又は前後に伸びるように照射可能であればよい。 Further, the linear laser light emitted from the light emitting unit 20 is assumed to be in the three directions of front and rear, left and right, and upper and lower, but is not limited to this, and is irradiated so as to extend at least to the left and right or front and rear. If possible.
また、本実施形態においては軸が水平な管Ｋについて罫書き線を引いたが、軸が鉛直な管Ｋについても当然に同様にして罫書くことができる。
また、図３に示すように、例えばガスタンク等の球体についても、中心水平線を罫書く場合には罫書き治具１を上下方向又は水平方向に配置することで行うことが可能である。
Further, in the present embodiment, the ruled line is drawn for the tube K whose axis is horizontal, but naturally the ruled line can also be marked for the tube K whose axis is vertical.
Further, as shown in FIG. 3, for example, a spherical body such as a gas tank can be formed by arranging the ruler jig 1 in the vertical direction or the horizontal direction when ruled the central horizontal line.
また、管Ｋに罫書く場合に、頂点（基準点）から左右両方向に罫書き治具１を移動させるのではなく、図４に示すように例えば右方向だけに罫書き治具１を移動させると螺旋状に罫書くことができる。 Further, when scoring on the tube K, the scoring jig 1 is not moved in both the left and right directions from the apex (reference point), but is moved only in the right direction, for example, as shown in FIG. And can be ruled in a spiral.
また、図５に示すように、右壁１３ｃ又は左壁１３ｄに設置した水準器１５を用いることで、鉛直方向を基準点とした４５度の点、９０度の点、１３５度の点をそれぞれ罫書くことができる。
また、水準器１５は罫書き治具１に設置されることで便利になるが、必須の構成要素ではない。
Moreover, as shown in FIG. 5, by using the level 15 installed on the right wall 13c or the left wall 13d, a 45 degree point, a 90 degree point, and a 135 degree point with the vertical direction as a reference point are respectively obtained. Ruled lines can be drawn.
Moreover, although the level 15 becomes convenient by being installed in the ruler jig 1, it is not an essential component.
基準点針１４はマーキングできれば針に限られず、他のペン等のマーカーであってもよい。 The reference point needle 14 is not limited to a needle as long as it can be marked, and may be a marker such as another pen.
また、エルボー（曲管）の任意角度の横断切断を行う場合にも本実施形態の罫書き治具１を使用することで容易に罫書くことが可能である。
さらには、エビ管を直管で作る場合でも、本実施形態の罫書き方法を直管に対して繰り返すことで、従来より遥かに容易に罫書き、そしてエビ管を作成することができる。
なお、曲管とは管の方向を変えるために滑らかに、例えば９０度折れ曲がる管のことであり、一方、図６に示すようにエビ管Ｅとは直管を継ぎ接ぎして折れ曲がる管のことである。
Further, even when the transverse cutting of the elbow (curved pipe) at an arbitrary angle is performed, it is possible to easily make a ruled line by using the ruler jig 1 of the present embodiment.
Furthermore, even when the shrimp pipe is made of a straight pipe, the scoring method and the shrimp pipe can be created much more easily than before by repeating the scoring method of the present embodiment for the straight pipe.
The bent pipe is a pipe that bends smoothly, for example, 90 degrees to change the direction of the pipe, while the shrimp pipe E is a pipe that is bent by connecting straight pipes as shown in FIG. is there.
また、罫書き治具１の材質はステンレスに限られるものではない。 Further, the material of the ruler jig 1 is not limited to stainless steel.
また、発光部２０の高さ位置が十分に高ければ、発光部２０が管Ｋ同士を繋ぐフランジを超えて罫書き作業を行うこともできる。
さらには、脚部１２の高さが十分あれば脚部１２でフランジを超えて罫書き作業を行ってもよい。
Further, if the height position of the light emitting unit 20 is sufficiently high, the scoring operation can be performed beyond the flange where the light emitting unit 20 connects the tubes K to each other.
Further, if the height of the leg portion 12 is sufficient, the scoring operation may be performed with the leg portion 12 beyond the flange.
