この考案は、鋼板の開先等の切断に際し、鉛直方向の切
断と斜方向の切断とを、火口を交換するのみで可能にし
たガス切断用器具に関する。[Detailed Description of the Invention] This invention relates to a gas cutting tool that makes it possible to cut in the vertical direction and in the diagonal direction by simply replacing the tip when cutting a groove in a steel plate.
従来のガス切断用器具は、器具本体に、鉛直方向の切断
火口と、斜方向の予熱火口とが形成されている。A conventional gas cutting tool has a vertical cutting port and an oblique preheating port formed in the main body of the device.
したがって、第１図に示すように、鋼板にの２段開先切
断に際し、鉛直方向の切断および鉛直線に対し約４５度
程度の斜方向までのＡ部の切断は可能であるが、鉛直線
に対し約４５度以上のＢ部の切断においては、予熱炎の
不足による加熱不足により、切断が不可能であり、鋼板
の裏返しなど、切断準備に多くの時間を要するとともに
、クレーンの使用による危険性の高い作業を行なってい
る。Therefore, as shown in Fig. 1, when making two-stage bevel cutting on a steel plate, it is possible to cut in the vertical direction and cut in the A section diagonally at an angle of about 45 degrees to the vertical line; When cutting section B at a temperature of about 45 degrees or higher, it is impossible to cut due to insufficient heating due to insufficient preheating flame, and it takes a lot of time to prepare for cutting, such as turning the steel plate over, and there is a danger of using a crane. Performing high-level work.
この考案は、前記の点に留意してなされたものであり、
つぎにこの考案を、その１実施例を示した第２図以下の
図面とともに、詳細に説明する。This idea was made with the above points in mind,
Next, this invention will be explained in detail with reference to the drawings from FIG. 2 showing one embodiment thereof.
第２図は、鉛直方向の切断の場合を示し、同図において
、１は切断機に鉛直方向に保持される切断用器具本体、
２は器具本体１の下面の一側に鉛直方向に一体に形成さ
れた火口取付部であり、外周に螺溝が形成されている。FIG. 2 shows the case of cutting in the vertical direction, and in the same figure, 1 is a cutting instrument main body held in the cutting machine in the vertical direction;
Reference numeral 2 denotes a crater mounting portion that is vertically integrally formed on one side of the lower surface of the device main body 1, and has a spiral groove formed on its outer periphery.
３は器具本体１の下面の他側に斜方向に一体に形成され
た予熱火口、４は切断用酸素供給管の接続される継手で
あり、火口取付部２に連通している。Reference numeral 3 denotes a preheating nozzle integrally formed on the other side of the lower surface of the instrument main body 1 in an oblique direction, and 4 a joint to which a cutting oxygen supply pipe is connected, which communicates with the nozzle attachment part 2 .
５および６はそれぞれ可燃性ガスおよび予熱用酸素の供
給管の接続される継手であり、側継手５，６は予熱火口
３に連通している。5 and 6 are joints to which flammable gas and preheating oxygen supply pipes are connected, respectively, and the side joints 5 and 6 communicate with the preheating nozzle 3.
７は鉛直方向の切断火口、８は取付部２の螺溝に螺合す
るバグナツトであり、取付部２に鉛直方向の切断器ロア
を着脱自在に装着する。Reference numeral 7 denotes a vertical cutting tip, 8 a bag nut screwed into the threaded groove of the mounting part 2, and a lower vertical cutter is detachably attached to the mounting part 2.
そして、この第２図に示す鉛直方向の切断器ロアを装着
した場合、鉛直方向の切断が可能である。When the vertical cutter lower shown in FIG. 2 is attached, vertical cutting is possible.
つぎに、斜方向の切断の場合を示した第３図および第４
図について説明する。Next, Figures 3 and 4 show the case of diagonal cutting.
The diagram will be explained.
９は鉛直方向の基部１０に中継管１１を介して一体に形
成された斜方向の切断火口であり、基部１０が前記バグ
ナツト８により取付部２に着脱自在に装着される。Reference numeral 9 denotes a diagonal cutting nozzle integrally formed with a vertical base 10 via a relay pipe 11, and the base 10 is removably attached to the mounting portion 2 by the bag nut 8.
そして、この場合、鉛直線に対し４５度以上の傾斜を有
する切断が可能である。In this case, it is possible to cut at an angle of 45 degrees or more with respect to the vertical line.

作業能率が向上する。As described above, according to the gas cutting device of this invention, the vertical cutting tip and the diagonal cutting tip are selectively and detachably attached to the mounting part of the device body, so that only the tip can be replaced. Vertical and diagonal cutting is possible with a simple operation, and the cutting ability in the diagonal direction is only a few percent lower than that in the vertical direction, and the diagonal direction, that is, the bevel angle, is also lower. It is consistent, highly accurate, improves quality, and improves work efficiency without the long and dangerous preparation work required in the past.
