Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable band saw machine for cutting a material to be cut by a band saw stretched around a saw wheel.
[0002]
[Prior art]
Conventionally, there was a stationary band saw machine equipped with a light, but a portable band saw machine or a portable band saw machine was fixed to a stand or the like so as to stand upright and cut a material to be cut on a guide table None of the contour cutting band saws were equipped with lights. For this reason, in the cutting work in a dark work place, the work is performed by illuminating the vicinity of the cutting portion with another light, or the work is cut in a dark state where the material to be cut cannot be seen well.
[0003]
[Problems to be solved by the invention]
Since the conventional portable band saw machine is brightened when the working place is dark, it is necessary to prepare another light, and it is troublesome to secure a power source and to wind the cord. In general, it is common to bring a band saw machine at the cutting point of the material to be cut. The time to move the light each time, and even if it is illuminated by the light, it is cut by the light irradiation position. There are problems such as hand shadows on the material, black lines indicating the cutting position cannot be seen well, and it may be difficult to align the cutting position. The same applies to so-called contour cutting in which a portable band saw is fixed to a vertical shape with a stand or the like, and a workpiece is cut on a guide table.
[0004]
Also, cutting work without using a light makes it difficult to see the cutting position of the material to be cut, so it is impossible to cut straight or it is necessary to work in an unreasonable posture such as bringing a face close to the cutting area. There was a problem.
[0005]
An object of the present invention is to provide a portable band saw machine that can solve the above-described problems of the prior art and can easily and accurately perform a cutting operation in a dark work place.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes first and second saw wheels, and first and second saw wheel bases that rotatably support the first and second saw wheels at both ends of a housing. A band saw stretched between the first and second saw wheels, a guide table provided on the first saw wheel base for guiding a material to be cut, and a motor for rotating the first saw wheel A switch handle disposed on the first saw wheel base and coupled to the first saw wheel base and the housing, wherein the second saw wheel base is formed of the band saw. In a portable band saw machine having a support member that extends to the housing in a direction perpendicular to the traveling direction, the support member of the second saw wheel base extends from above the second saw wheel in the direction of the first saw wheel. A light for irradiating light is provided, and the band saw, the band saw, and the cut object are cut by the light. It has a contact of wood, one feature that has to illuminate the guide table at the same time.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to FIGS. 1 and 2 showing an embodiment.
[0008]
Saw wheel bases 4 and 5 that rotatably support the saw wheels 2 and 3 are provided at both ends of the housing 1, and a band saw 6 is stretched between the saw wheels 2 and 3. The saw wheel bases 4 and 5 are provided with band saw guides 7 and 8 for sandwiching and guiding the band saw 6, and the saw wheel base 4 is provided with a guide table 9 for guiding the workpiece 16 when cutting the workpiece 16. A motor 14 is provided in the housing 1, and the saw wheel 2 is rotated by the motor 14. A switch handle 11 is provided on the saw wheel base 4, and a switch 12 for rotating and stopping the motor 14 is provided on the switch handle 11.
[0009]
In the saw wheel base 5, a band saw 6, a light 10 that illuminates the contact point of the band saw 6 and the workpiece 16 and the guide table 9 at the same time is provided, and is turned on / off by a light switch 13 provided on the saw wheel base 5. . The light 10 is provided so that the central axis 10a of the irradiated light and the travel line of the band saw 6 coincide.
[0010]
In the above configuration, when cutting the workpiece 16, the switch handle 11 is held with one hand, the auxiliary handle 15 is held with the other hand, the switch 12 is operated to rotate the motor 14, that is, the band saw 6. The cutting material 16 is pressed and cut from above.
[0011]
A case where the portable band saw is used standing will be described with reference to FIG.
[0012]
After the portable band saw machine is stood and fixed on a stand or the like (not shown) and the band saw 6 is rotated, the material 16 to be cut is placed on the guide table 9 and the material 16 to be cut is pressed against the band saw 6 and cut. At this time, the position of the light 10 is located above the guide table 9.
[0013]
When the vicinity of the material to be cut 16 is dark, the light switch 13 is operated and the light 10 is turned on to work. Conversely, when the vicinity of the material to be cut 16 is bright, the light switch 13 is operated and the light 10 is turned off. Work.
[0014]
In this way, the light 10 can be easily turned on and off according to the surrounding situation, and workability can be improved. Further, since the central axis of the light irradiated by the light 10 is made coincident with the center of the traveling line of the band saw 6, the following effects can be obtained.
[0015]
In other words, when the band saw 6 is irradiated from a diagonal direction with another light, the shadow of the band saw 6 reflected on the material 16 to be cut becomes a shadow having a certain width. There is a problem that it becomes difficult to see. On the other hand, when the central axis of the irradiated light coincides with the center of the traveling line of the band saw 6, the shadow of the band saw 6 reflected on the material 16 to be cut is only the width of the band saw 6 and only under the band saw 6, that is, at the cutting position. Since no shadow is formed, there is no hindrance to the cutting operation, and accurate cutting is possible.
[0016]
【The invention's effect】
According to the present invention, the band saw, the light for simultaneously irradiating the band saw and the contact point of the material to be cut and the guide table are provided above the band saw, so that even when the work place is dark, it is possible to save the trouble of preparing another light or moving it. . Also, depending on the irradiation position of the light, shadows of the hand can be made on the material to be cut, and the black line indicating the cutting position does not disappear well, and work with an unreasonable posture such as bringing the face close to the cutting area. This makes it easier and more accurate to cut in a dark work place. The same applies to contour cutting, in which a portable band saw machine is stood and fixed on a stand, etc., and the material to be cut is cut on the guide table, and a light is provided above the guide table that is not affected by chips during cutting. Therefore, it is not affected by light failure.
