Description

Background Art [0002] Blades of circular saws for imitation marble

The present invention relates to a circular saw blade, and more particularly to a circular saw blade for cutting artificial marble.

Circular saw blades are mainly used for cutting metal materials such as steel sheets. A circular cutting saw blade for cutting a steel material is a blade in which a cutting tip (hereinafter referred to as a cutting tip) is periodically formed along the outer periphery thereof as shown in FIG. 1, and is used for cutting a metal pipe, Is used.

Recently, circular saw blades have been used for cutting artificial marble. The artificial marble is different from the steel material in shape and is intended to imitate the performance of marble, so its characteristics are similar to stone. When a circular saw blade for fluorescent material cutting is used for cutting artificial marble, the cutting efficiency is lowered due to the phase difference of the material to be cut, or a cutting failure, for example, a rough cut surface is generated.

Korean Utility Model Registration Application No. 2019830007030 shows a circular saw blade for cutting stone. As shown in Fig. 1, the saw blade main body 4 has a shape in which the inclined ridge 3 and the inclined recess 5 are formed on the peripheral edge thereof.

Such a method may be suitable for cutting a stone, but as a saw blade manufacturer, there arises a problem that a circular saw blade for cutting a stone, which has a completely different structure in addition to a circular saw blade for a section, is produced.

Accordingly, there is a continuing need for a new circular saw blade having a basic structure of a circular saw blade for cutting a fluorescent material, which is suitable for cutting artificial marble.

A problem to be solved by the present invention is to provide a new circular saw blade having a basic structure of a circular saw blade for cutting a fluorescent material and suitable for cutting artificial marble.

In order to solve the above problems, the circular saw blade for cutting artificial marbles according to the present invention has a cutting tip periodically attached along the outer periphery thereof,

The cutting tip

It is made of 20 to 50 micron diameter powder,

The plane shape is a symmetrical trapezoid in which the two sides are perpendicular to the rotation direction of the main body, and the length of the short side is longer than the thickness of the main body,

The front shape is a symmetrical trapezoid with two sides perpendicular to the cutting plane of the main body, the shape of which the length of the short side is longer than the thickness of the main body and the long side is located at the upper end of the saw blade,

And the tips are regularly arranged at predetermined intervals along the rotating direction of the saw blade.

In the present invention, the powder constituting the cutting tip of the circular saw blade for cutting artificial marble is made of industrial diamond or a cemented carbide such as tungsten carbide.

In the present invention, when the size (diameter) of the powder is larger than 50 mu m, the hardness of the tip becomes weak and it becomes difficult to provide sufficient strength required for cutting the artificial marble containing the stones. Further, if the size (diameter) of the powder is smaller than 20 μm, there arises a problem that the price is increased only without a difference in cutting power. In a preferred embodiment of the present invention, the powder uses a powder having a diameter of 30 to 40 탆.

In the planar shape of the cutting tip according to the present invention, the short side of the rear end is preferably 50 to 500 占 퐉, preferably 70 to 300 占 퐉, more preferably 100 to 200 占 퐉 thick as compared with the main body. The length of the long side of the front end is preferably 500 to 2000 占 퐉, more preferably 700 to 1500 占 퐉, and even more preferably 1000 to 1200 占 퐉 in relation to the thickness of the main body.

In the frontal shape of the cutting tip according to the present invention, the shorter side of the lower end is preferably 50 to 500 占 퐉, preferably 70 to 300 占 퐉, more preferably 100 to 200 占 퐉 thick as compared with the main body. The length of the longer side of the upper end is preferably 500 to 2000 占 퐉, more preferably 700 to 1500 占 퐉, and even more preferably 1000 to 1200 占 퐉 in relation to the thickness of the main body.

In the side shape of the cutting tip according to the present invention, the angle is important in a state where the cutting tip is attached to the saw blade, preferably, the inclination angle of the tip is 10 to 20 degrees, and the inclination angle of the front end is in a range of 5 to 15 degrees .

The circular saw blade for cutting artificial marble according to the present invention is suitable for cutting artificial marble while having a structure in which a cutting tip is formed on a circumference like a circular saw blade for cutting a steel material, so that a smooth cutting surface can be formed.

Further, the circular saw blade for cutting artificial marble according to the present invention can be easily manufactured by simple shape of the cutting tip, and has a high price competitiveness.

Hereinafter, the present invention will be described in detail with reference to examples. The following examples illustrate the invention and are not intended to limit the invention.

3, the artificial marble cutting saw blade 100 according to the present invention is a circular saw blade having a 6 in diameter 110, a 60 saw blade 120 number, and a 2.0 mm thickness. The cutting tips 130 are formed by welding a cutting tip in the shape of a rectangular parallelepiped body made of tungsten carbide particles having a diameter of 30 to 40 탆 to the front end of the saw blade 120, cutting the tip, do.

As shown in FIG. 4, in the manufactured circular saw blade 100, the cutting tips 130 have a trapezoidal planar shape a and a trapezoidal frontal shape b. In the trapezoidal shape of the plane, the long side 131 of the front end in the rotational direction is 2400 μm, the length 132 of the short side in the rear end in the rotational direction is 2100 μm, and the height of the trapezoid is 1000 μm. In the trapezoidal shape of the front surface, the length of the lower side short side 133 is 2100 占 퐉, the length of the upper long side 134 is 2400 占 퐉, and the height of the trapezoid is 3500 占 퐉.

As shown in FIG. 5, the cutting tip 130 has a tip inclination angle 135 of 15 degrees at a side surface and a shear inclination angle 136 of 10 degrees at a side surface.

As shown in FIG. 6, the artificial marble plate was cut by using the circular saw blade 100 for cutting the manufactured artificial marble, and the cutting plane is shown in (a). In contrast to this, the artificial marble plate was cut using a circular saw blade for cutting steel, and the cut surface was shown in (b).

As shown in Fig. 6, when the artificial marble was cut using artificial marble cutting circular saw blade 100, the artificial marble was smooth and the rough cutting surface was shown when the artificial marble was cut using the circular saw blade for cutting the section steel. Respectively.
