Description

Technical Field

[0001] The utility model belongs to the technical field of diamond saw blades, and in particular relates to an ultra-thin diamond saw blade. Background Art

[0002] At present, the diamond circular saw blades in China mainly include pressureless sintering saw blades, hot pressing sintering saw blades, high frequency welding saw blades, laser welding saw blades and other types of diamond saw blades. Pressureless and hot pressing sintering saw blades generally have a short lifespan, while conventional laser welding saw blades are generally welded with ordinary blade heads or blade heads with several chip grooves. These saw blades either have insufficient strength and thick teeth, or have thick bases, wear off teeth and low cutting efficiency.

[0003] Therefore, there is an urgent need for a diamond saw blade with sufficient strength, thinner saw teeth and high cutting efficiency. Utility Model Content

[0004] In view of this, the technical problem to be solved by the utility model is to provide an ultra-thin diamond saw blade to avoid the troubles of the previous diamond saw blades with thick teeth, low cutting efficiency and easy wear.

[0005] In order to solve the above technical problems, the utility model discloses an ultra-thin diamond saw blade, comprising:

[0006] A saw blade base, the saw blade base having a plurality of saw teeth separated by U-shaped grooves, the saw teeth having a T-shaped groove located at an outer edge, and a strip groove located in the middle of an inner edge, the T-shaped groove and the strip groove being connected to each other;

[0007] A chip reducing groove provided on the sawing teeth and located between the T-shaped groove and the strip groove;

[0008] The diamond cutter head is sintered and formed in the T-shaped groove and the strip groove, and the diamond cutter head protrudes from the saw blade base.

[0009] According to an embodiment of the utility model, the chip reducing grooves extend from the edges on both sides of the sawing teeth to the diamond tool head.

[0010] According to an embodiment of the present invention, the arc length of the strip groove is 1 / 3 of the arc length of the saw teeth.

[0011] According to an embodiment of the utility model, the chip reducing groove is 0.5-1.5 mm lower than the saw blade base.

[0012] According to one embodiment of the utility model, the diamond cutter head protrudes from the saw blade base by 0.5-1.0 mm.

[0013] Compared with the prior art, the utility model can obtain the following technical effects:

[0014] By setting T-shaped grooves and strip grooves on the inner and outer rings of the saw teeth in combination with sintered diamond cutter heads, I-shaped cutting blades of varying lengths are formed to accelerate cutting and avoid the trouble of welding larger and thicker cutter heads at both ends. The overall thinning design has high cutting efficiency.

[0015] Of course, any product implementing the present utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Please refer to Figure 1 , Figure 1 It is a schematic diagram of an ultra-thin diamond saw blade according to an embodiment of the utility model.

[0022] As shown in the figure, an ultra-thin diamond saw blade includes: a saw blade base 10, the saw blade base 10 has a plurality of sawing teeth 30 separated by a U-shaped groove 20, the sawing tooth 30 has a T-shaped groove 31 located at the outer edge, and a strip groove 32 located in the middle of the inner edge, the T-shaped groove 31 and the strip groove 32 are connected to each other; a chip reducing groove 33 is arranged on the sawing tooth 30 and located between the T-shaped groove 31 and the strip groove 32; a diamond cutter head 40 sintered and formed in the T-shaped groove 31 and the strip groove 32, and the diamond cutter head 40 protrudes from the saw blade base 10.

[0023] In one embodiment of the utility model, the saw blade base 10 is selected from a high-strength steel base, with a through hole for installation in the center, and multiple groups of saw teeth 30 are arranged on the outer edge of the outer ring, and are spaced by U-shaped grooves 20 to achieve chip removal. The outer edge of the saw teeth 30 is provided with a T-shaped groove 31, and the inner edge is provided with a strip groove 32, which is located in the center and is shorter than the T-shaped groove 31. The two are connected to each other and sintered together to form a diamond cutter head 40, thereby enhancing the cutting strength, while avoiding the trouble of welding a heavy cutter head at the end of the saw teeth 30, and the overall design is light and thin.

[0024] In addition, a chip reducing groove 33 is provided in the middle section of the sawing tooth 30, that is, between the T-shaped groove 31 and the strip groove 32, and is arranged on both sides of the T-shaped groove 31, forming a cutting edge that is offset from the saw blade base 10, which can further enhance the cutting ability and improve the cutting efficiency.

[0025] Specifically, the chip reduction groove 33 extends from the edges of the saw teeth 30 on both sides to the diamond cutter head 40, forming two cutting edges from the edges of the saw teeth 30 to the inside, and the thin design is more suitable for feeding. Preferably, the chip reduction groove 33 is 0.5-1.5mm lower than the saw blade base, which does not affect the overall strength.

[0026] The arc length of the strip groove 32 of the utility model is 1 / 3 of the arc length of the sawing teeth 30, and the strip groove 32 is uniformly designed and has strong practicality.

[0027] In addition, the diamond cutter head 40 protrudes from the saw blade base 10 by 0.5-1.0 mm, thereby enhancing the cutting strength.

[0028] In summary, the utility model forms I-shaped cutting blades of different lengths by arranging T-grooves 31 and strip grooves 32 on the inner and outer rings of the sawing teeth 30 in combination with a sintered diamond bit 40, thereby accelerating cutting and avoiding the trouble of welding larger and thicker bits at both ends. The overall thinning design has high cutting efficiency.

[0029] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
