Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of diamond blades, and more specifically, to a diamond blade with a long service life. Background Art
[0002] Blades are a general term for thin circular knives used to cut solid materials. They are one of the commonly used knives for cutting aluminum profiles by high-speed rotation. Since aluminum alloys are rich in carbon, silicon, iron, manganese and other elements, their material is relatively hard and uneven, so the requirements for sawing are relatively high.
[0003] At present, diamond blades are commonly used cutting tools. During cutting operation, due to the principle of frictional heat generation, the diamond blade will generate heat as a whole. Most existing diamond blade heat dissipation methods generally open heat dissipation holes on the substrate to dissipate the heat of the substrate. However, the existing heat dissipation method is not ideal. During long-term high-speed operation, the temperature of the blade will rise sharply. If the heat cannot be dissipated in time, it will cause heat to accumulate on the substrate of the saw blade. Once the temperature exceeds the substrate's tolerance limit, cracking will occur, causing the saw blade to be scrapped as a whole, which is very dangerous and prone to explosion. Utility Model Content
[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a diamond blade with a long service life which ensures the service life of the diamond blade.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A diamond blade with a long service life comprises a substrate, a plurality of blade teeth are installed on the outer side of the substrate, the blade teeth comprise an alloy substrate, the alloy substrate is embedded in the outer surface of the substrate, the alloy substrate is provided with diamond abrasive particles on the outer surface of the substrate, four main heat dissipation grooves are opened on the substrate, a plurality of heat-conducting columns are fixedly connected between the inner walls on both sides opposite to each other of the main heat dissipation grooves, a heat-conducting strip is embedded in the alloy substrate, the other end of the heat-conducting strip penetrates into the main heat dissipation groove and is fixedly connected to the heat-conducting column.
[0007] The utility model is further configured as follows: a mounting hole is provided at the center of the base.
[0008] The utility model is further configured as follows: the four main body heat dissipation grooves all extend out of the front and rear side surfaces of the base body, and the four main body heat dissipation grooves are arranged on the base body in a circular array with the mounting hole as the center line.
[0009] The utility model is further configured as follows: heat dissipation fins are fixedly connected to the outer surfaces of the two opposite sides of the heat-conducting column, and a plurality of heat dissipation holes are opened on the heat dissipation fins.
[0010] The utility model is further configured as follows: a plurality of heat dissipation holes are arranged on the heat dissipation fins in a rectangular arrangement.
[0011] The utility model is further configured as follows: the heat dissipation fins are located in the heat dissipation slots of the main body.
[0012] The advantage of the utility model is that during the cutting process, the tooth part of the diamond blade generates heat, which can be conducted to the heat-conducting column through the heat-conducting strip, and quickly dissipated by the heat dissipation fins. Different from the heat dissipation method of the existing diamond blade, this method can improve the heat dissipation effect of the diamond blade while ensuring the strength of the diamond blade, and try to avoid the accumulation of heat on the substrate and the occurrence of cracks due to poor heat dissipation, further ensuring the service life of the diamond blade.

[0021] See also Figure 1-4 , the utility model provides the following technical solutions:
[0022] Specifically, it refers to a diamond blade with a long service life, including a base 1, a plurality of cutting teeth 2 are installed on the outer side of the base 1, and the number of the cutting teeth 2 is set according to the actual circumference of the base 1. No limitation is made on the number here. A mounting hole 3 is opened at the center of the base 1, so the diamond blade is installed on the rotating shaft of the cutting equipment through the mounting hole 3.
[0023] Specifically, the blade 2 includes an alloy matrix 21, which is embedded in the outer surface of the substrate 1. The alloy matrix 21 is made of high-alloy steel (i.e., high-speed steel) containing a large amount of carbon (C), tungsten (W), molybdenum (Mo), chromium (Cr), vanadium (V) and other elements. This allows the blade 2 to maintain high hardness under high-speed cutting and high heat conditions (about 500°C), and also allows the blade 2 to have better thermal conductivity. The alloy matrix 21 is located on the outer surface of the substrate 1 and is provided with diamond abrasive particles 22. The use of diamond abrasive particles 22 makes the blade 2 sharper, more efficient and more durable.
[0024] Specifically, four main heat dissipation grooves 4 are opened on the base 1, and the four main heat dissipation grooves 4 extend out of the front and rear side surfaces of the base 1. The four main heat dissipation grooves 4 are arranged on the base 1 in a circular array with the mounting hole 3 as the midline. A plurality of heat-conducting columns 5 are fixedly connected between the inner walls on the opposite sides of the main heat dissipation groove 4. The number of the plurality of heat-conducting columns 5 is set according to the actual length of the main heat dissipation groove 4 and is not limited in quantity. A heat-conducting strip 23 is embedded in the alloy base 21, and the other end of the heat-conducting strip 23 penetrates into the main heat dissipation groove 4 and is fixedly connected to the heat-conducting column 5, and the heat conduction The strip 23 and the heat-conducting column 5 are both made of copper. Since copper has good thermal conductivity, when the diamond blade is in the cutting process, the blade 2 generates heat, and this heat can be conducted to the heat-conducting column 5 through the heat-conducting strip 23, and the heat is quickly dissipated by the heat-conducting column 5. Different from the heat dissipation method of the existing diamond blade, this method can improve the heat dissipation effect of the diamond blade while ensuring the strength of the diamond blade, and try to avoid the accumulation of heat on the substrate 1 and the occurrence of cracks due to poor heat dissipation, thereby further ensuring the service life of the diamond blade.
[0025] In this embodiment, the heat-conducting column 5 also has the effect of a reinforcing rib, which can be used to increase the strength of the main heat dissipation slot 4 and further ensure the overall strength of the base 1.
[0026] Specifically, heat dissipation fins 6 are fixedly connected to the outer surfaces on opposite sides of the heat-conducting column 5, and a plurality of heat dissipation holes 7 are opened on the heat-conducting fins 6. The plurality of heat dissipation holes 7 are arranged in a rectangular manner on the heat-conducting fins 6. At the same time, the heat dissipation fins 6 are located in the main body heat dissipation groove 4, so that the heat on the heat-conducting column 5 can be conducted to the heat dissipation fins 6. At the same time, when the blade is running at high speed, the air flow can flow in the heat dissipation holes 7, which further accelerates the heat conduction effect on the blade 2, avoids excessive heat accumulation on the blade 2 as much as possible, and further ensures the use effect of the alloy matrix 21.
[0027] The working principle of the diamond blade with a long service life provided by the utility model is as follows: during the cutting process, the tooth 2 of the diamond blade generates heat, which can be conducted to the heat-conducting column 5 through the heat-conducting strip 23, and the heat on the heat-conducting column 5 can be conducted to the heat dissipation fin 6. At the same time, when the blade is running at high speed, air flow can flow in the heat dissipation hole 7, and the air flow can take away the heat on the heat dissipation fin 6.
