ができるようになっている。On the base 1, the second fire shield 13 facing the first sparks 13 is provided.
A fire shield 15 is capable of undulating and a shaft support 4 of the support arm 3 is provided.
It is pivoted apart from the section. This second fire extinguisher 15
As shown in FIG. 2, when the cutter cover 9 is superposed on the cutter cover 9, the cutter cover 9 and the rotary cutter 8 are separated from each other by the dead weight of the first sparks 13 by following the fall of the cutter cover 9 by its own weight. It is formed in a shape that can be covered from the opposite side, and its inner surface 16 is placed on the outer peripheral surface of the cutter cover 9. Further, when the second spark eliminator 15 is superposed on the cutter cover 9, the support arm 3 does not stand up due to the elastic force of the spring 11, so that the spark splattered behind the rotary cutter 8 is removed by the second spark eliminator. It can be received inside 15.
支持腕３の一側において基台１上には、金属製のワーク
Ｗを所定の位置に把持、固定するための公知の万力１８
が配設されている。On the base 1 on one side of the support arm 3, there is a known vise 18 for gripping and fixing the metal work W at a predetermined position.
Is provided.

る火の粉を確実に受けることができる。Next, the operation of the present embodiment will be described. First, the work W is fixed at a predetermined position on the base 1 by the vise 18. Next, the operator grips the gripping rod 12 to slightly lay down the support arm 3 around the shaft support 4 and superimposes the second powder dust 15 on the depressed cutter cover 9. Subsequently, if the worker presses the support arm 3 downward while operating the drive motor 6 to rotate the rotary cutter 8, the work W can be cut by the rotary cutter 8. At this time, the rotary cutter 8 moves from the cutting point of the work W.
Although the sparks are scattered to the front side in the rotation direction (arrow a in FIG. 2), the sparks are almost contained in the first spark shaving device 13 and do not scatter around the cutting machine. Rotating cutter 8
The powder of fire also scatters on the rear side in the rotating direction of No. 2, but this powder of fire is stored in the second powder guard 15 and does not scatter around the cutter. Therefore, it is possible to perform the cutting work smoothly and safely without the operator hitting the sparks. Further, since the second fire dust shield 15 superposed on the cutter cover 9 during the cutting operation rotates around the pivot 17 according to the downward movement of the cutter cover 9 due to its own weight, the position of the rotary cutter 8 changes. However, it is possible to reliably receive the sparks scattered behind the rotary cutter 8.
切断作業が終了して第２火の粉除け１５を枢軸１７回り
に反転させ、把持杆１２より手を放すと、ばね１１の弾
発力により支持腕３は自動的に起立する（第１図参
照）。When the cutting work is completed and the second fire powder shelter 15 is inverted around the pivot 17 and the hand is released from the grip rod 12, the elastic force of the spring 11 causes the support arm 3 to automatically stand up (see FIG. 1). .
尚、第２火の粉除け１５をカッタカバー９に重合させる
と、該カッタカバー９の自重により支持腕３が起立する
ようなことはないので、切断機のコンパクト化が図れそ
の持ち運び等を簡単に行うことができる。It should be noted that, when the second fire powder shelter 15 is superposed on the cutter cover 9, the supporting arm 3 does not stand up due to the weight of the cutter cover 9, so that the cutting machine can be made compact and can be easily carried. be able to.

とができる。C. As described above, according to the present invention, the base of the cutting machine is provided with the first spark keeper on the front side in the rotation direction of the rotary cutter,
In addition, a second powder shavings is pivotally supported on the rear side in the direction of rotation so as to be capable of undulating and separated from the shaft supporting portion of the supporting arm of the cutter unit, and the second powder shavings are superposed on the cutter cover of the cutter unit. In this state, the cutter cover and the rotary cutter are moved to the first position by following the fall of the cutter cover by their own weight.
Since it is formed in a shape that can be covered from the side opposite to the fire extinguisher, when the cutting work is performed by superimposing the second fire extinguisher on the cutter cover, the fire dust and cutter debris will scatter forward from the cutting point in the cutter rotation direction. Can be suppressed by the first powder shaving, and further, the scattering of the sparks and the cutter fragments on the rear side in the cutter rotation direction can be suppressed by the second powder shaving.

ができる。In particular, the second spark eliminator is rotatably supported on the base at a position on the rear side in the rotation direction of the rotary cutter and away from the axial support of the support arm of the cutter unit, and in the process of attaching and detaching the work to the base. Since the second powder shavings can be held at a lying position far away from the work, a wide work space for attaching and detaching the work can be secured, and the work efficiency can be improved. Moreover, in a state where the second spark shavings are superposed on the cutter cover, the exposed portion of the rotary cutter on the operator side (that is, the rear side in the cutter rotation direction) is exposed from the side opposite to the first spark shavings while the rotary cutter is being cut. Since it can be widely covered regardless of the height change of the cutter, it is extremely effective in preventing the scattering of sparks and cutter debris to the rear side in the cutter rotation direction, and prevents workers from being hit by the sparks and cutter debris. The work can be prevented and the work can be performed smoothly and safely.

ことができ、汎用性を高めることができる。Furthermore, since the second powder eliminator can be installed on the base separately from the first powder pulverizer and the cutter unit, it can be retrofitted to an existing cutting machine or a commercially available cutting machine without any difficulty, and thus is versatile. Can be increased.
