Embodiment 1

[0045] Roughen the area where the cutter head needs to be set on the metal base part (the material is specifically 45# steel) (the specific method is barbs) to obtain a roughened metal base part with a roughness of 3mm;

[0046] Put the silane coupling agent KH560 and diamond-metal powder in a mixer, mix for 1 hour at room temperature and normal air pressure for surface modification treatment, and then granulate to obtain spherical particles, that is, surface-modified diamond metal particles ; Wherein, the silane coupling agent KH560 is 5% of the diamond-metal powder mass, and the diamond-metal powder is a mixture of alloy powder and diamond, and the mass ratio of the alloy powder to diamond is 9:1; the particle size of diamond is 10~ 800 mesh; the composition of the alloy powder is iron 32wt.%, copper 15wt.%, nickel 5wt.%, tin 5wt.%, cobalt 15wt.%, manganese 3wt.%, silicon 2wt.%, chromium 8wt.% and tungsten carbide 15wt.%, the particle size of the alloy powder is 60-70 mesh; ...

Embodiment 2

[0049] The method for preparing the diamond metal bond article with reference to embodiment 1, the difference is that the shape of the metal base part and the cutter head is different from that of embodiment 1; the gained diamond metal bond article is marked as 2# product, wherein, it comprises A rectangular cutter head, the length of the cutter head is 40mm, the width is 10mm, and the height is 10mm.

Embodiment 3

[0051] According to the method for embodiment 1, the diamond metal bond product is prepared, and the difference is that the shape of the metal matrix part and the cutter head is different from that of embodiment 1; the gained diamond metal bond product is denoted as 3# product, wherein, including two A rectangular cutter head, the length of the cutter head is 40mm, the width is 10mm, and the height is 10mm.

[0052] figure 2 It is a schematic diagram of the roughened metal matrix part in embodiments 1-3, image 3 It is a schematic diagram of a diamond metal bond product in Examples 1 to 3, Figure 4 It is the physical figure of the diamond metal bond product in Examples 1 to 3; Figure 2~4 Among them, 1# corresponds to embodiment 1, and 2# corresponds to embodiment 2, and 3# corresponds to embodiment 3; figure 2 and 3 In each example, the roughened metal matrix piece and the diamond-metal bonded piece are given a front view and a top view, respectively. like figure 2 ...

Abstract

The invention provides a diamond metal bond product and its integral molding manufacturing method and application, belonging to the technical field of diamond abrasives. The integral molding and manufacturing method of diamond metal bond products provided by the present invention comprises the following steps: roughening the metal matrix to obtain a roughened metal matrix; using a silane coupling agent to modify the surface of the diamond-metal powder Granulate after treatment to obtain surface-modified diamond metal particles; place the roughened metal matrix and surface-modified diamond metal particles in a forming steel mold for integral compression molding, and perform pressureless sintering after demoulding to obtain diamond metal particles Bonding parts. The diamond metal bond product provided by the invention has excellent performance, and the grinding efficiency is obviously better than that produced by the traditional process.

Description

technical field [0001] The invention relates to the technical field of diamond abrasives, in particular to a diamond metal bond product and its integral molding manufacturing method and application. Background technique [0002] The traditional production process of diamond abrasives adopts the high-temperature hot pressing method. Usually, the diamond cutter head is prepared by hot pressing with a graphite mold, and then the diamond cutter head is connected to the metal matrix by brazing. However, the grinding efficiency of diamond abrasives prepared in the above-mentioned traditional way still needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a diamond metal bond product and its integral molding manufacturing method and application. The diamond metal bond product provided by the present invention has excellent performance, and the grinding efficiency is obviously better than products produced by traditional techni...
