Embodiment 1

[0024] see Figure 1-2 , figure 1 It is a schematic plan view of a base body of a diamond circular saw blade according to an embodiment of the present invention. figure 2 It is a schematic plan view of a sawtooth segment with diamond abrasive grains according to an embodiment of the present invention. Depend on Figure 1-2 It can be seen that the diamond saw blade of this embodiment includes a disc-shaped saw blade base 1; six sawtooth sections 2 are evenly distributed on the edge of the saw blade base, and chip pockets 4 are arranged between each sawtooth section, and each sawtooth section There are wavy sawtooths on them, and the number of sawtooth peaks 5 is five. In addition, each sawtooth section is also provided with cooling holes 6. The number of cooling holes 6 on each sawtooth section is four. The number of cooling holes The diameter is 3 mm; the saw teeth are provided with diamond abrasive grains 3; the inclination angle 11 between two adjacent saw tooth segments...

Embodiment 2

[0026] The nickel-based solder powder of this embodiment is made of the following components according to the following ratio: Cu: 10.3wt%, Mn: 17.2wt%, Ti: 4.5wt%, Al: 7.2wt%, Sn: 2.2wt%, The balance is Ni. The preparation method is as follows:

[0027] According to the stated ratio, put the Cu, Mn, Ti, Al, Sn and Ni raw materials in the smelting furnace, and heat them to 1250°C under the pressure of 5 MPa to melt the raw materials; then fill the powder collector with Inject high-purity argon; use high-purity argon to atomize the melted raw materials, and the atomization pressure is 4MPa to obtain nickel-based brazing powder. The shape of the obtained powder is spherical, the particle size is less than 200 μm, and the melting point is 970 ° C.

Embodiment 3

[0029] The nickel-based solder powder of this embodiment is made of the following components according to the following ratio: Cu: 12.8wt%, Mn: 21.5wt%, Ti: 7.2wt%, Al: 9.8wt%, Sn: 3.2wt%, The balance is Ni. The preparation method is the same as in Example 2. The obtained nickel-based solder powder had a melting point of 940°C.

Abstract

The invention relates to a brazing process of a diamond saw blade. The brazing process is characterized by comprising the following steps: (1) pre-treating a saw blade matrix of steel 45: sequentially performing sand-blasting, alkaline-washing and acid-washing on the saw blade matrix of the steel 45; (2) preparing a brazing material: mixing nickel-based brazing powder with the average particle size of 10-200mu m with diamond particles with the average particle size of 3-50mu m; (3) pre-coating the brazing material: pre-coating the mixed brazing powder on the surface of saw teeth of the saw blade matrix; and (4) brazing under a vacuum condition at the temperature of 850-980 DEG C for 20-30 minutes. The diamond saw blade obtained by the brazing process has the advantages of low porosity, firm combination between diamond and the matrix, high finished product rate and stable quality.

Description

technical field [0001] The present invention relates to a brazing process, more specifically the present invention relates to a brazing process of a diamond saw blade. Background technique [0002] Diamond cutting tools are high-efficiency cutting tools developed in the 1980s. In the past two decades, diamond saw blades with artificial diamond heads as cutting edges have been widely used in construction, transportation, chemical, wood processing, non-ferrous metal cutting and other industries. The proportion of using diamond saw blades is increasing, especially in natural stone processing, highway construction and concrete engineering, diamond saw blades have become the main factor determining the progress and cost of the project. [0003] The working conditions of diamond saw blades are relatively harsh. High speed, vibration and high temperature put forward strict requirements on the welding of diamond blades. Higher and higher. In the prior art, the methods for connecti...
