Description

Grinding wheel cutting piece

The present invention relates to a grinding wheel cutting piece, in particular to a grinding wheel cutting machine, and a grinding wheel cutting piece structure having a reinforcing auxiliary piece bonded to a peripheral portion of at least one side of the center mounting hole to strengthen the cutting strength.

According to the conventional grinding wheel, the structure is widely applied to a high-speed rotary cutting object, and the structure thereof is as shown in the first figure, wherein the conventional flat type grinding wheel 1 is installed at a high speed such as a grinder with a center hole 2 In the rotary cutting machine or the machine tool, the grinding wheel piece 1 can cut the metal or hard object by the high-speed rotation of the grinder, but the conventional grinding wheel piece 1 has a weak overall structure, insufficient strength, and is easy to cut metal or hard workpieces. It is easy to have problems and disadvantages that the entire grinding wheel piece 1 is broken, the use effect is not good, and the service life is not long, and the heat dissipation effect of the conventional grinding wheel piece 1 is poor, in the process of rotating the workpiece piece at high speed by the grinding wheel piece 1 It is easy to generate high heat, which will cause embrittlement, breakage or breakage, which will seriously affect the safety of its use and reduce the life of the product. This is a problem that is currently to be solved in the use and industrial utilization of the conventional grinding wheel 1 .

In addition, in the related prior patent documents, for example, the new patent case of "The Structure of Tool-Free Disassembled Grinding Wheels" of the Republic of China Patent No. M460746 and the Invention Patent of No. I441714 "Chemical Mechanical Polishing Dresser" disclose the above. The typical grinding wheel structure shown in the first figure still has the above-mentioned conventional structure of the grinding wheel 1 which is fragile and insufficient in strength, and is easy to be broken, and the overall heat dissipation effect of the grinding wheel 1 Poor and embrittled damage or breakage seriously affects the problems and disadvantages of the safety and service life of the grinding wheel 1 .

In addition, if the applicant applied for approval in the previous application, the new patent case of the “Wheel Cutting Disc” of the Republic of China Patent Gazette No. M547449, has initially revealed the structure and technology of the strength of the central part of the enhanced grinding wheel cutting piece.

In the above-mentioned prior art or the patent wheel, the grinding wheel piece is weak in use and operation, and the whole structure is fragile and difficult to dissipate heat, so that the grinding wheel piece can cause the grinding wheel piece to break and generate high heat when used for cutting metal or hard workpiece. The embrittlement, damage or breakage of the grinding wheel plate seriously affects the safety and the service life of the grinding wheel.

Therefore, the grinding wheel cutting piece of the present invention comprises: a cutting piece body, the cutting piece body is provided with a mounting hole at a center of the circle, which can be rotated on a rotating shaft of a rotating machine to cut an object; and a plurality of series The reinforcing bump is coupled to the surface of at least one surface of the cutting piece body, and is integrally formed with the cutting piece body, and a plurality of heat dissipation grooves are formed between the reinforcing protrusions.

Further, in the above-described grinding wheel cutting blade of the present invention, the reinforcing projection has a rectangular block shape.

The utility model relates to a grinding wheel cutting piece of the invention, which is characterized in that the plurality of reinforcing protrusions are integrally formed and bonded to the surface of at least one side of the cutting piece body, so that the overall strength of the cutting piece body as a whole is increased, and the cutting piece body is prevented from being Cutting the metal or hard object without the problem of breakage, and forming a plurality of heat dissipation grooves between the reinforcing bumps, can effectively and greatly increase the overall heat dissipation area and effect of the cutting piece body, and can greatly increase the The cutting piece body is used for cutting workpieces at high speed The rapid cooling effect, without the problem of damage or breakage of the cutting body, greatly improves the safety and service life of the grinding wheel cutting piece of the creation, and further improves the industrial utilization value and economic benefit of the creation.

The first picture is a perspective view of a conventional grinding wheel; the second picture is a perspective view of the grinding wheel cutting piece of the present invention; the third picture is a cross-sectional enlarged view of the A-A' of the third figure; and the fourth picture is a partial enlarged view The structure of the reinforcing bump and the heat dissipating groove of the grinding wheel cutting piece of the present invention is shown; the fifth figure is a preferred application example of the grinding wheel cutting piece of the present invention.

Referring to the second, third and fourth figures, the grinding wheel cutting blade 100 of the present invention comprises a cutting piece body 10, which is made of diamond and resin and then placed into a mold for press forming. Further, it is formed by high-temperature barbecue. The cutting blade body 10 is provided with a mounting hole 11 at a center portion thereof for rotation on a rotating shaft 210 of a rotating machine 200 (as shown in FIG. 5) to cut an object 300.

a plurality of reinforcing bumps 20 bonded to the surface of at least one side of the cutting blade body 10, and integrally formed with the cutting blade body 10 during the manufacturing process, and between the reinforcing bumps 20 The plurality of heat dissipation grooves 21 are formed to increase the heat dissipation area of the entire blade body 10 and allow the heat dissipation airflow to quickly flow. The shape of the reinforcement bumps 20 is not limited. In the present invention, a rectangular block configuration is taken as an example.

Please refer to the fifth figure, which is a preferred application diagram of the grinding wheel cutting blade 100 of the present invention, wherein the cutting blade body 10 is mounted on the rotating machine 200. The rotating shaft 210 is used to cut the application state of the object 300. The type of the rotating machine 200 is not limited. In the present example, the series of grinding wheel cutting machines can be metal or hard workpieces when the cutting is performed. When the sheet body 10 drives the high speed rotation through the rotating machine 200 and the rotating shaft 210 to cut the object 300 downward, the reinforcing bumps 20 of the cutting piece body 10 provide the overall strength enhancement effect of the cutting piece body 10 without In addition, the heat dissipation groove 21 between the reinforcing bumps 20 provides the function of rapidly flowing the high heat and the heat dissipation air generated when the cutting blade body 10 is rotated at high speed to cut the object 300, so that the cutting body 10 does not There will be any problems of embrittlement, breakage or breakage due to poor heat dissipation at high temperatures.
