Abstract

<P>PROBLEM TO BE SOLVED: To provide a diamond saw with a very simple structure and manufacturing process capable of executing rapid cutting without deformation, and also, capable of significantly reducing manufacturing costs. <P>SOLUTION: A plurality of fan-like copper alloy metal pieces are welded to the outer periphery of an annular hard steel piece provided with a shaft hole. A plurality of openings are opened to each copper alloy metal piece. The width of the opening is larger than the diameter of a diamond granule. The diamond granule is inserted to the opening part of each copper alloy metal piece. The metal faces on both sides of each opening are vertically and simultaneously compressed with a die. The metal faces on both sides of the opening are compressed by the die and deformed. A saw face with a concavoconvex appearance is formed by pressing and coating the diamond granules to the direction of the opening part so as to constitute the diamond saw capable of executing rapid cutting without deformation. Therefore, the manufacturing costs can be significantly reduced. The structure and manufacturing process of the diamond saw can be extremely simplified. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a kind of diamond saw, and more particularly to a structure of a diamond saw that can be rapidly cut without deformation and has a simple structure.

  As shown in FIG. 2, the diamond saw 10a is generally formed by rolling a circular copper plate or a relatively soft metal plate by a machine and bonding diamond granules to the outer periphery of the annular copper plate, and the cutting effect of this structure is extremely good. . However, the diamond saw 10a is made of a copper material or a relatively soft metal plate, and can only perform slow cutting due to insufficient strength of the copper material. When used for high speed cutting, the diamond saw 10a can be severely deformed and damaged. To remedy this drawback, the industry has provided a diamond metal sintered diamond saw 10 as shown in FIG. It mixes various metal powders and diamond granules, puts them in a characteristic mold, forms a powder mass by cold pressure method, and strengthens diamond-containing stones at a high temperature of 850 degrees Celsius to strengthen it A lump 101 is formed, and each diamond polishing ring lump 101 is welded to the outer peripheral portion of an annular steel piece 120 having a shaft hole. Such diamond metal sintered diamond saw 10 must use high-cost diamond granules and various metal powders, and can easily cause lesions on the skin of workers when diamond granules and metal powders are mixed. Also, the number of peripheral diamond manufacturing machines 10a is very expensive, the power consumption is extremely low, air pollution is generated, the manufacturing process is cumbersome, the manufacturing cost is extremely high, and the product unit price is a mechanical rolling type copper diamond saw 10a. It is difficult to meet the cost reduction requirements of each industry. Further, the cutting effect of the diamond metal sintered diamond saw 10 of FIG. 2 is inferior to that of the copper diamond saw 10a manufactured by the mechanical rolling method of FIG.

  As can be seen from the foregoing, the mechanical rolling diamond saw 10a of FIG. 2 has the advantages of low manufacturing cost, good cutting effect, and easy manufacture, but lacks strength. Since the diamond metal sintered diamond saw 10 is mainly made of steel, its strength is good and it does not deform, but the cutting effect is somewhat inferior and its manufacturing cost is extremely high.

  In view of the drawbacks of the above two types of diamond saw manufacturing methods, the present invention has low manufacturing cost, simple manufacturing process, high sharpness, and has the advantages of the products by the above two known manufacturing methods. The objective is to provide a new diamond saw.

  The invention of claim 1 is a diamond saw, wherein a plurality of fan-shaped copper alloy metal pieces are welded to the outer periphery of an annular hard steel piece having a shaft hole, and a plurality of openings are opened in each copper alloy metal piece, The width of the opening is larger than the diameter of the diamond granule, and after the diamond granule is inserted into the opening of each copper alloy metal piece, the metal surfaces on both sides of the opening are simultaneously pressed up and down with a mold, The diamond saw is characterized in that a granulated saw surface is formed by press-coating the granules so that rapid cutting can be performed without deformation.

  The present invention provides a novel diamond saw that has low manufacturing cost, simple manufacturing process, high sharpness, and has the advantages of the products produced by the above two known manufacturing methods. The structure of the present invention is novel because it is not described in the publications distributed before the application and is not publicly used.

  According to the present invention, as shown in FIG. 3, a plurality of fan-shaped copper alloy metal pieces 200 are welded to the outer peripheral portion of an annular hard steel piece 20 having a shaft hole, and as shown in FIG. A plurality of openings 200a are provided in the copper alloy metal piece 200, and as shown in FIG. 5, the diamond granules 30 are inserted into the openings 200a, and the width of the openings 200a is slightly larger than the diameter of the diamond granules 30. After inserting the granule 30 into the opening 200a portion of each copper alloy metal piece, the metal surfaces on both sides of the opening 200a are pressed from above and below with a mold, the metal surfaces on both sides of the opening 200a are deformed by pressing the mold, The diamond granule 30 is press-coated in the direction, and as shown in FIG. 6, a diamond saw 2000 is formed which can be rapidly cut without deformation as an uneven saw surface. Its manufacturing cost is greatly reduced and its structure and manufacturing process are very simple.

  The above embodiments do not limit the scope of the present invention, and any modification or alteration in detail that can be made based on the present invention shall fall within the scope of the present invention.

It is a structure display figure of a known metal sintered diamond saw. It is a structure display figure of a known mechanical rolling type diamond saw. It is a welding display figure of the annular | circular shaped hard steel piece of this invention, and several fan-shaped copper alloy metal pieces. It is an opening display figure of the fan-shaped copper alloy metal piece of the present invention. It is an insertion display figure of the diamond saw to opening of the fan-shaped copper alloy metal piece of this invention. It is a local three-dimensional view in which a diamond saw is inserted into the opening of the fan-shaped copper alloy metal piece of the present invention, and the diamond granule is pressed and coated on the copper alloy metal piece using a mold to form an uneven saw surface.
