Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a stone material using a saw blade.
Related to the cutting device .

[0002]

2. Description of the Related Art Conventionally, in the cutting of stone materials by a so-blade, for example, as shown in FIG.
Both ends of a lateral elevating rail 53 are slidably fitted to the left and right columns 52, 52, and are connected to an elevating motor 54 by a screw rod 55,
55 are screwed into both ends of the elevating rail 53 and screwed 55, 5
The rotation of 5 raises and lowers the elevation rail 53,
The blade support member 57 supporting the blade 56 is moved up and down by the rail 5
3 is installed on the blade support member 57, and the traveling mode is provided on the blade support member 57.
The blade support member 57 is reciprocated along the elevating rail 53 by the rotor 58 and the so blade 56 is rotated by the blade motor 59 to cut the stone 61 on the carriage 60. Was there.

[0003]

However, in the above-mentioned prior art, the blade support member 57 reciprocates along the ascending / descending elevator rail 53, and has a large number of movable parts and an elevator rail. -Since the load of the tool 53 is lifted up and down by the screw 55, the so blade 56 is likely to vibrate when the stone is cut, and this vibration causes the particles of the diamond-containing tip 62 on the outer periphery of the so blade 56. The diamond-containing tip 62 is liable to wear due to peeling off.
Since the blade 56 is only supported at the center portion, it is easy for the stone 61 to escape to the soft side due to the hard and soft spots of the cutting point and bend, and to prevent this, it becomes a thick blade, which reduces the cutting efficiency. However, there is a problem that a large amount of cutting powder is discharged and the yield of stone material is also reduced.

Therefore, the present invention is a sobler when cutting stones.
Is less likely to cause vibration and wear of the diamond-containing tip, and the blade is hard to escape due to hard and soft spots at the cutting point of the stone material, making it possible to make a thin blade, cutting efficiency and yield of stone material. Therefore, the present invention intends to improve and thereby solve the above-mentioned problems of the prior art.

That is, the stone cutting device according to the present invention is provided with a heavy weight rotatably provided around the base shaft 1 in the left-right direction at a fixed position.
To have the support block via the lateral direction of the support shaft, the support block

[0006]

In the present invention, when the stone material is cut, one side of the stone material is hard and the other side is soft, and the saw blade attempts to bend toward the soft side, but it is in contact with both side surfaces of the saw blade. drive roller and the roller supported by the arm there are Ru der as to prevent bending of the saw blade. On this occasion,
The roller supported by the arm maintains a substantially constant height by the arm and the link even when the lower peripheral surface, which is the cutting portion of the saw blade, is lowered, and the contact with the stone is prevented. Also,
Because the saw blade is supported by a heavy support block,
ー The blade rotates stably, and moreover, with the support shaft of the saw blade
Instead, the motor is fixed to the support block to prevent blurring
The saw blade is rotated by rotating the drive roller that doubles as
This prevents vibration of the saw blade during stone cutting.
It will be stopped and the cutting will be smooth. In addition, support block
The drive roller at the position from the base axis that serves as the fulcrum of rotation.
-Abut the both sides of the blade, and
Rotate the saw blade in the direction that the blade faces the base side.
Vibration, the load is applied to the center of gravity on the base axis side.
It is hard to occur and can be cut more smoothly.
