BACKGROUND OF THE INVENTION
The present invention relates to dust collection for collecting cutting powder when a workpiece is cut by a cutting machine that rotates a circular saw blade such as a table-type slide circular saw or a hand-held circular saw. It relates to the device.
[0002]
[Prior art]
As shown in FIGS. 3A and 3B, the cutting machine that rotates the circular saw blade to cut the workpiece includes a motor 22 that drives the circular saw blade 21 to rotate. There is a table-type cutting machine 2 that cuts the workpiece 3 placed on the material mounting table 24 by pushing down. Further, as shown in FIG. 4A, a circular saw blade 61 and a motor 62 for rotating the circular saw blade 61 are provided, and the circular saw blade 61 is advanced in the cutting direction by holding a handle 63 to be cut. There is a hand-cut type cutting machine 6 that cuts.
[0003]
In both the tabletop-type cutting machine 2 and the hand-held type cutting machine 6, when the workpiece 3 is cut, the cutting powder is scattered around and the cutting site is contaminated. There is a need to do.
[0004]
Therefore, in the table-type cutting machine 2, as shown in FIGS. 3A and 3B, a discharge port 27 is formed in the upper saw blade cover 25 of the circular saw blade 21, and a dust bag 28 is attached. . Further, as shown in FIG. 3C, the cut powder can be collected in the dust collector 4 by connecting a suction hose 41 of the dust collector 4 instead of the dust bag 28.
[0005]
As shown in FIG. 4 (a), there is a push-type cutting machine 6 to which a collection case 64 for collecting cutting powder is attached. The collection case 64 has a discharge lid 65 for taking out the collected dust. A connection port 66 of the suction hose 41 of the dust collector 4 is also formed in the discharge lid 65. Therefore, as shown in FIG. 4 (b), the suction hose 41 is connected to the connection port 66, and the cut powder can be collected by the dust collector 4 while being cut by the cutting machine 6.
[0006]
[Problems to be solved by the invention]
However, in the tabletop cutting machine 2, the cutting powder collected from the discharge port 27 formed in the upper saw blade cover 25 is only the one that is rolled up in the direction of the discharge port 27 by the circular saw blade 21. The cutting powder wound up in a different direction from the discharge port 27 and the cutting powder wound up by the wind from the motor 22 are scattered around and cannot be recovered.
[0007]
On the other hand, in the push-type cutting machine 6, most of the cutting powder can be collected in the collection case 64. However, every time the collection case 64 is full, if the discharge lid 65 is opened and the cutting powder is discharged, it takes time to discharge the cutting powder. Further, if the cutting operation is performed while the suction hose 41 of the dust collector 4 is connected to the collection case 64, the trouble of discharging the cutting powder can be eliminated, but the suction hose 41 makes the handling of the cutting machine 6 inconvenient. There is a problem that.
