Description

[0001]
TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band saw that can be used in both a horizontal type and a vertical type in which a portable band saw is swingably and detachably mounted on a stand and can be used as a stationary type.
[0002]
[Prior art]
There is a demand that the portable band saw machine B (hereinafter referred to as main body B) shown in FIG. 6 be mounted on a stand S shown in FIG. 7 and used as a stationary type.
[0003]
Both the main body B and the stand S have a well-known configuration, but will be briefly described. The main body B is stretched over a frame 1 containing a motor 2, a pair of saw wheels 4 (a driven saw wheel 4 a, a driving saw wheel 4 b) provided on both sides of the frame 1, and a saw wheel 4. It comprises an endless saw blade 3 circulating by the rotation of the wheel 4, a guide plate 6 provided on the drive side of the frame 1 and near the saw blade 3, and the like.
[0004]
The stand S includes a base 7 on which a workpiece 17 to be described later is placed, a fixed vise 8 and a movable vise 9 provided opposite to the upper surface of the base 7, and a rear (the right and left sides in FIG. ), A hinge 11 swingably attached via the hinge shaft 10, a holder 12 provided in front of the hinge 11 and attached with the main body B, and the like.
[0005]
The holder 12 is fixed to the front surface of the hinge 11 via two bolts. The main body B is provided with a positioning hole (not shown) provided on the rear side of the frame 1 in a pin 13 on the front surface of the holder 12 and provided in front of the holder 12. The knob bolts 14 passing through the holes 12 a are screwed into the screw holes 5 provided on both side surfaces of the frame 1, so that the knob bolts 14 are attached to the holder 12.
[0006]
When used as the stationary type described above, there are two cutting methods. One is a cutting as a horizontal band sawing machine for cutting the material 17 to be cut by the weight of the main body as shown in FIG. The other is to raise the main body B at a right angle to the base 7 of the stand S, as shown in FIGS. This is so-called contour cutting, in which a contour table 16 on which the workpiece 17 is fixed and on which the workpiece 17 is placed is placed on the guide plate 6 of the main body B, and the workpiece 17 is cut close to the saw blade 3 as shown in FIG.

[Problems to be solved by the invention]
In the cutting method described above, particularly in the case of contour cutting, there is a problem that burrs and burrs are easily generated on the cut surface of the cut material 17 depending on how the worker feeds the cut material 17. Therefore, there is a problem in that a disk grinder or the like must be prepared and burrs must be removed.
[0008]
An object of the present invention is to make it possible to easily remove generated burrs and burrs using the present apparatus.
[0009]
[Means for Solving the Problems]
The above object is achieved by diverting a rotating saw wheel and providing a grinding file in a circular shape from the center on a side surface of the saw wheel.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of the band saw board of the present invention will be described with reference to FIGS.
[0011]
FIG. 1 is a view showing a state in which a grinding file 18 of the present invention is mounted on a driving saw wheel 4b. The grinding file 18 is provided on the side surface of the driving saw wheel 4b in a circular shape from the center. FIG. 2 is an enlarged view of a grinding file 18 formed in a circular shape on a side surface of the driving saw wheel 4b in FIG. FIG. 3 shows a state in which contour cutting is performed. Usually, this is performed when the material 17 to be cut is chamfered or chamfered, or when a material having a deformed shape and the vise fixing is difficult is cut. FIG. 4 is a front view showing a state where the apparatus is installed for cutting contours.
[0012]
A saw blade 3 is mounted on an outer peripheral portion of the saw wheel 4, and the saw blade 3 circulates by rotation of the saw wheel 4, and the workpiece 17 is cut by the saw blade 3. In this embodiment, the driving saw wheel 4b is used, but a thin file-shaped grinding file 18 is attached to the center of the saw wheel on one side of the saw wheel 4b. The burrs on the cut surface of the workpiece 17 generated at the time of cutting are pressed against the grinding file 18 of the rotating driving saw 4b to remove the burrs.
[0013]
According to the above-described embodiment, after the cutting work (especially contour cutting), burrs and burrs generated on the cut surface of the material to be cut 17 can be easily removed by using this machine, and it is necessary to prepare a disk grinder and the like. Is also gone.
[0014]
【The invention's effect】
As described above, according to the present invention, burrs and burrs generated on a cut surface can be removed by using the present machine, so that it is not necessary to prepare a disk grinder or the like, and work efficiency is improved. In addition, one product can perform work for two models.
