Problems solved by technology

During the use of large-size diamond saw blades, as the cutting time increases and the cutting depth increases, the contact area between the saw blade and the stone becomes larger and larger, which will cause a sharp rise in cutting temperature, and the accumulation of heat will affect the life of the saw blade. The main reasons: first, the overheating of the saw blade will change the metallographic structure of the saw blade base material, reduce the overall strength and wear resistance of the base material, and cause the saw blade base to deform during continuous cutting; second, the saw blade is used In the process, excessiv

[0050] Example 2:

[0051] The processing method of the circular saw blade with drop-shaped oblique hole structure comprises the following steps:

[0052] Step 1: Select the circular plate of the saw blade base for use;

[0053] Step 2: Put the circular plate blank of the saw blade base on the high-power water jet cutting equipment and fix it;

[0054] Step 3: Start the waterjet cutting equipment, first cut the installation hole 7, then cut the heat dissipation groove 6, and then process the chip removal groove 3 on the edge of the saw blade base; finally, when cutting the heat dissipation hole 5, it is necessary to continuously adjust the water jet The angle between the spray head 8 and the saw surface 9 ensures that the inner wall of the processed cooling hole 5 is an inclined inner wall;

[0055] Step 4: Derusting and smoothing the two surfaces of the saw blade substrate processed by the waterjet;

[0056] Step 5: Connect the diamond blade 2 and the sawtooth 4 by brazing...

Abstract

The invention provides a circular saw blade of a drop-shaped inclined hole structure and a machining method. The circular saw blade comprises a saw blade base body, and a mounting hole is formed in the center of the saw blade base body; sawteeth which are evenly distributed are machined on the outer circumference of the saw blade base body. A chip groove is formed between every two adjacent sawteeth; blades are arranged on the edges of the sawteeth; uniformly-distributed heat dissipation holes are formed in the saw blade base body and are close to the chip grooves; uniformly-distributed heat dissipation grooves are formed in the saw blade base body and are close to the mounting holes; the inner walls of the heat dissipation holes are in a water drop shape by adopting transitional arc inner walls. According to the circular saw blade, the circular saw blade can be effectively suitable for high-strength rock cutting, the heat dissipation and chip removal effects of the saw blade are good, the cutting efficiency is high, the saw blade is easy to machine, the working efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of diamond saw blades, in particular to a circular saw blade with a drop-shaped oblique hole structure and a processing method thereof. Background technique [0002] With the rapid development of social economy, the demand for stone materials in the construction industry is increasing, and higher requirements are put forward for the efficiency and cost of stone mining. Diamond saw blades are the most commonly used cutting tools in stone mining, and their scrap volume is far Much larger than other types of knives. During the use of large-size diamond saw blades, as the cutting time increases and the cutting depth increases, the contact area between the saw blade and the stone becomes larger and larger, which will cause a sharp rise in cutting temperature, and the accumulation of heat will affect the life of the saw blade. The main reasons: first, the overheating of the saw blade will change the metallographic structur...
