In addition, the cutting groove 13 is formed between the cutting tips 20. The cutting groove 13 has an arc-shaped curved portion formed inside the unit cutting tip 20a that is plastically bonded to the left side of the cutting tip 20 and the unit cutting tip 20g that is predetermined bonded to the right side. The grooves formed between the shanks 12 are curved to form a curved arc shape on the left and right sides of the cutting tip 20 to be curved to coincide with the cutting tip 20.

The curved portions of the unit cutting tips 20a and 20g are made of radians (r, r) of approximately 2.5 to 100 cm in diameter.

Furthermore, the components of the unit cutting tips 20a-20g include iron (Fe), copper (Cu), cobalt (Co), zinc (Zn), nickel (Ni), tungsten (W), copper-tin (CuSn) and silver. The cutting powder of diamond or cemented carbide is mixed with one or more metal powders of (Ag) and manganese (Mn) at different ratios. That is, any one or more of a plurality of metal powders are included, and the cutting powder of diamond or cemented carbide is mixed in a predetermined ratio. The cutting powder mixed in at least one metal powder has a size of 20 to 100 mesh and is 0.01% by weight or more of the total weight ratio.

The plurality of unit cutting tips 20a-20g integrally fired by the cutting tips 20 are arranged at random intervals or at regular intervals. That is, in Fig. 3a, unit cutting tips 20a-20g in which a predetermined proportion of cutting powder is mixed with one or more metal powders may be composed of A to G or more, and such unit cutting tips 20a-20g are in sequence. Can be arranged randomly as is or randomly. 3B, the plurality of unit cutting tips 20a, 20b, and 20c may be randomly arranged in sequence or randomly. In addition, in FIG. 3C, the plurality of unit cutting tips 20a and 20b may be alternately arranged.

In FIGS. 3A to 3C, the spacings of the unit cutting tips 20a-20g may be arranged in the same width as the cutting tips 20, but as shown in FIG. 3D, the unit cutting tips 20a, 20c, 20e, and 20g may be arranged. The width is the same, and the unit cutting tips 20b, 20d, and 20f may be identically arranged. Furthermore, with the cutting tip 20, the unit cutting tips 20a-20g may be integrally arranged in different widths. And the shape and shape of the unit cutting tips (20a-20g) may be integrally molded into the same or different shapes or shapes.

Meanwhile, in the structure of the cutting tip 20 applied in the present invention, a curved portion is formed on the outer surface of the unit cutting tips 20a and 20g joined to the left and right sides of the cutting tip 20 as shown in FIG. 3E.

Figure 3f is composed of nine unit cutting tips, Figure 3g shows a modified embodiment consisting of five unit cutting tips.

Such a cutting tip manufacturing method of the cutting saw of the present invention will be described with reference to the drawings showing the manufacturing process of Figures 4a to 4f and the flow chart of FIG.

First, a circular disk having a predetermined diameter having a rotating hole 11 coupled to the rotating shaft of the cutting machine at the center thereof, a cutting groove 13 formed at regular intervals, and a shank 12 formed between the cutting grooves 13 ( 10) to prepare (S10).

And the unit cutting tip (20a-20g) to the cutting powder of diamond or cemented carbide, iron (Fe), copper (Cu), cobalt (Co), zinc (Zn), nickel (Ni), tungsten (W), copper-tin One or more metal powders of (CuSn), silver (Ag), and manganese (Mn) are mixed at different ratios (S11). That is, it may be mixed in a plurality of mixing ratios by various mixing ratios. At this time, the cutting unit 20a-20g is mixed in one or more metal powder, each of the cutting powder is within 20 ~ 100 mesh, is mixed at about 0.01% by weight or more in the total weight ratio. For example, the cutting powder of diamond or cemented carbide may be mixed with the metal powder of copper (Cu) and iron (Fe) in a total weight ratio of 0.05% by weight or more. Therefore, since the weight ratio of the cutting powder is changed to any one or more metal powders, the unit cutting tips 20a-20g having various mixing ratios may be configured.

In this way, the metal powder and the cutting powder mixed at different ratios are primary-molded at predetermined pressures in a mold having a predetermined unit cutting tip 20a-20g (S12). The pressure exerted on the mold during the primary molding is approximately 15-20 Kg / Cm 2 .

In FIG. 4A, primary shaping forms each unit cutting tip 20a-20g corresponding to the shape of the puncher while applying relatively small pressure. In addition, a mold is applied to mold the unit cutting tips 20a and 20g joined to the left and right ends of the cutting tip 20 inwardly curved arc shapes. It is to be formed as a cutting groove 13 between the cutting tip (20).

In FIG. 4B, each of the unit-formed cutting tips 20a-20g firstly formed is sequentially arranged in one cutting tip molding mold having a predetermined shape and volume, and second molding is performed at a pressure greater than the first molding (S13). ). At this time, the secondary shaping each unit cutting tip (20a-20g) corresponding to the shape of the completed cutting tip while applying a greater pressure than the primary shaping. At this time, the pressure applied when the unit cutting tip (20a-20g) is secondary molded is approximately 110 ~ 150Kg / Cm 2 .

In addition, the present invention is a multi-sandwich type, the unit cutting tips (20a-20g) can be joined by selectively arranging several to several tens. Although the present invention shows a structure in which seven unit cutting tips 20a-20g are bonded to each other, the unit cutting tips 20a-20g may be added or subtracted according to the use or size of cutting saws.

The secondary molded unit cutting tips 20a-20g are alternately arranged in a carbon mold in a predetermined shape and volume (S14). In other words, by sequentially arranging the unit cutting tips (20a-20g) in the carbon mold to shape the shape of the cutting tip (20).

The carbon mold is placed in a furnace and sintered at a predetermined pressure and temperature (S15). At this time, nitrogen gas (N 2 ) is added to the furnace to sinter as necessary. When sintering in the furnace, the sintering temperature is about 700 ~ 900 ℃, the pressure applied to the carbon mold is about 150 ~ 300Kg / Cm 2 . Nitrogen gas (N2) introduced into the furnace is approximately 30 Nm 3 / Hr.

Next, the carbon mold sintered in the furnace is charged to a cooling press and cooled at a predetermined temperature for a predetermined time (S16). At this time, the pressure applied to the cooling press at the time of cooling is approximately 300 to 350 Kg / Cm 2 . The cutting tips 20 formed from the cooled carbon molds are bonded onto all the shanks 12 formed at the edges of the disk 10 using silver solder or a laser (S17). The cutting tips 20 arranged as described above are integrally formed by the thickness and width of the shank 12 of the disk 10, and the arrayed cutting tips 20 are bonded to and fixed on the shank 12. . 4C to 4F show a sequence in which the bonded cutting tip 20 is joined to the shank 12.

In this way, the cutting tips are bonded to the edges of the cutting saw at regular intervals. The tips 20a-20g are formed at a greater pressure when forming the secondary than when forming the primary, and curved arcs on the left and right ends of the shank 12 to which the cutting tips 20 are respectively joined. Mold into shape.

On the other hand, the cutting tip 20 of the present invention is formed by 1.3 to 3 times longer than the conventional cutting tips to strengthen the initial cutting force.

6 is a graph showing the relationship between the length of the tip and the load acting when the cutting saw to which the cutting tip of the present invention is molded and joined to cut the cutting object. Here, the load applied to the initial cutting tip when cutting the object to be cut is shown, and it can be seen that the load R drops to approximately 90% after the load of 100% is applied. The cutting loads are reduced in series with the unit cutting tips 20a, 20c, 20e, and 20i, while the cutting loads are substantially horizontal at the unit cutting tips 20b, 20d, and 20f. The unit cutting tips 20b, 20d, and 20f between the unit cutting tips 20a, 20c, 20e, and 20i are tips having a slot-like function, and the unit cutting tips 20a, 20c, 20e, and 20i. Is a tip that cuts the cutting object directly, resulting in a higher mixing of the cutting powder. Therefore, the relationship between cutting efficiency and load may vary according to the arrangement of the mixing ratio of the metal powder and the cutting powder of the cutting tip of the present invention.

Furthermore, the graph of FIG. 7 shows the relationship between the total load of the cutting tip and the length of the tip bonded to the edge of the cutting saw. Here you can see that the load on one tip drops from 100% to approximately 90%.

The saw 1 to which the cutting tip 20 of such a structure is bonded is minimized in resistance and load caused by friction or contact with the cutting object when rotating for cutting, thereby preventing breakage or loss of the cutting tip 20. It can prevent.

According to the present invention, a structure of a cutting tip of a saw for cutting a cutting object such as stone, concrete, brick, or a wall surface has a plurality of different mixing ratios, respectively, than when a single reinforcing fixture is molded on one cutting tip. By arranging the unit cutting tips there is an advantage that the cutting efficiency for the cutting object is improved.

While the invention has been shown and described in connection with specific embodiments thereof, it is well known in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Anyone who has a can easily know.
