Embodiment 1

[0032] Such as figure 1 As shown, take two copper thin plates 1 with a thickness of 0.1mm, and uniformly coat the above-mentioned brazing material on both sides of each piece, the thickness of the brazing material layer is 0.5mm, and arrange diamonds Abrasive grains 2, diamond abrasive grains 2 are arranged outside the other sheet. The above-mentioned red copper sheet is superimposed, such as figure 1 As shown, a 2-layer superimposed body is obtained, and the two sides of the superimposed body are fixed with splints or molds. During the whole brazing process, a certain degree of pressure (3kg / cm2) is given to the superimposed body with splints or molds 2 ), so that on the one hand, it can prevent the warping of the superimposed body, and on the other hand, it can keep each layer of the superimposed body in close contact; then put it into a vacuum brazing furnace, vacuumize and heat according to the procedure, and braze After all the materials are melted, they are cooled with...

Embodiment 2

[0036] Such as figure 2 , image 3 with Figure 4 As shown, diamond multi-layer brazing and lateral cutting are applied as a preferred embodiment of the present invention. Two circular red copper sheets 3,5 with a thickness of 0.1mm are used as substrates, and on both sides of the red copper sheets 3,5 The side surface is coated with the above-mentioned brazing material, the thickness of the brazing material layer is 0.5mm, and the diamond abrasive grains 2 are arranged on the outer surface; a flange is processed on the ring matrix 4 in the middle, and the both sides of the flange are coated with The brazing material and the diamonds are placed in a row, and then the annular red copper sheet and the substrate are superimposed in the order of 3, 4, and 5. The annular red copper sheet 3 and 5 are distributed on both sides of the flange of the substrate 4, and the annular The annular ring surfaces of the red copper sheets 3 and 5 are matched with the flange surface of the matr...

Embodiment 3

[0040] refer to Figure 5 with Image 6 Shown, this is an example of a diamond multi-layer brazing, face-cutting application. The difference from Example 2 is that the metal base 7 is made of steel, and another 12 copper sheets 1 with a thickness of 0.1 mm are used as the base. Apply the above brazing material, the thickness of the brazing material layer is 0.5mm, according to the needs of the proposed block, place diamond abrasive grains 2 on the side of the metal substrate 7 close to the copper sheet and on both sides of the copper sheet, and then place the diamond abrasive grains on the metal substrate 7 The above-mentioned red copper thin plates are stacked in sequence, and the two sides of the superimposed body are fixed with splints or molds and then put into a vacuum brazing furnace. During the whole brazing process, a certain degree of pressure (10kg / cm 2 ), the metal substrate 7, the copper sheet 1 and the diamond abrasive grains 2 can be tightly brazed together. The...

Abstract

The invention discloses a multilayer diamond brazing body and a manufacturing method thereof. The multilayer diamond brazing body comprises 2 to 105 layers of metallic matrixes and diamond grits which are mutually overlapped, and the diamond grits are brazed between every two adjacent layers of metallic matrixes and on the outer later surfaces of one side or two sides of an overlapped body of 2 to 105 layers of metallic matrixes. The multilayer diamond brazing body is formed by overlapping and brazing a plurality of single-layer brazing bodies once, can integrate the advantages of single-layer brazing and multilayer sintering, has the sharpness of a single-layer brazing tool and the metallurgical combination of diamond and matrix, and also has the abrasion resistance of a multilayer sintering tool.

Description

technical field [0001] The present invention relates to a diamond multi-layer brazing body widely used in stone, ceramics, glass and concrete cutting diamond saw blades, diamond wire saw beads, diamond finger milling cutters for engraving, and diamond drill bits for drilling, and the manufacture of the aforementioned products method. Background technique [0002] There are two types of diamond tools in the prior art: single-layer brazing and multi-layer sintering: [0003] Single-layer diamond brazing technology, which is a technology in which diamond is directly welded to a specific substrate surface (such as a steel sheet) with brazing material under vacuum conditions. Diamond brazing tools are cutting and polishing tools, widely used in cutting and grinding of stone, ceramics, glass, concrete. Since the connection between the diamond and the substrate is a firm metallurgical bond, it is not easy to fall off. The diamond is in the shape of a mountain peak, and the cutti...
