Abstract
A high self sharping metal bonding agent diamond product is uniformly provided with diamond in a metal bonding agent tire body. The diamond blank zone in the metal bonding agent tire body is uniformly provided with non-metal compound material particles which cannot melt in the metal bonding agent tire body when sintering, the hardness of which is softer than the metal bonding agent, and the non-metal compound material particles can form a tire body with inhomogeneous structure. The high self sharping metal bonding agent diamond product has the advantage that the bean-shaped concave on the tire body surface of the metal bonding agent in the grinding process can make the surface accomplish the fatigue point corrosion condition quickly. In this way, the wearing ratio of the tire body can be increased, the self sharping can be increased, and the embedding strength of the tire body to the diamond cannot be affected. Therefore, the availability of the diamond can be increased, the efficiency of the grinding processing can be increased, and the service life of the product is increased.
Description
Technical field: the utility model relates to a kind of metal-bonded diamond goods of using as grinding tool.
Background technology: at present, the carcass that existing metal-bonded diamond goods adopt is that metal dust is through evenly mixing the back sintering, whole carcass has the homogeneous mechanical performance, the mechanical performance of this carcass is that mechanical strength improves, anti-wear performance is also high thereupon, efficient was higher when the material that adopts the diamond composition of this carcass manufacturing to be used for centering nonferromagnetic substance and strong nonferromagnetic substance carried out grinding, but, for rock type materials, when its compressive strength increases and nonferromagnetic substance reduces on the contrary, therefore, in hard and compact, the rock-boring of weak nonferromagnetic substance adds man-hour, and the diamond bit manufacturing is just very difficult.
Summary of the invention: the purpose of this utility model is to provide a kind of metal-bonded diamond goods, adopts the metallic bond carcass of inhomogeneous structure, overcomes the above-mentioned disadvantage of prior art metal-bonded diamond goods homogeneous texture carcass.
Technical solution of the present utility model is a kind of high self-sharpening metallic bond metal stone manufacture, it is an even distribution diamond in the metallic bond carcass, be not melted in the non-metallic composite material particle in the metallic bond carcass when diamond clear area evenly distributes the soft and sintering of hardness ratio metallic bond carcass in the metallic bond carcass, constitute the inhomogeneous structure carcass.
Description of drawings:
Fig. 1 is a self-sharpening metal-bonded diamond article construction schematic diagram.
Fig. 2 is metallic bond carcass and diamond state of wear schematic diagram.
Fig. 3 is the empty schematic diagram that the non-metallic particle that distributes in the carcass and the back that comes off thereof form.
The specific embodiment:
The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing, a kind of self-sharpening metal-bonded diamond goods, it is an even distribution diamond [2] in metallic bond carcass [1], be not melted in the non-metallic composite material particle [3] in the metallic bond carcass [1] when simultaneously the diamond clear area evenly distributes the soft and sintering of hardness ratio metallic bond carcass [1] in metallic bond carcass [1], formation inhomogeneous structure carcass.Referring to accompanying drawing 1.Among the figure, [4] are illustrated on the direction of motion in the goods work (among the figure shown in the arrow) rightabout, and the metallic bond carcass supports the shape of tail that diamond forms.
The particle diameter of non-metallic composite material particle [3] is greater than the abrasive size of diamond composition.
Non-metallic composite material particle [3] is spherical in shape.
When the metal-bonded diamond goods are used for grinding work piece, diamond [2] hardness ratio metallic bond carcass [1] hardness height, therefore tyre body abrasion forms arc pit [5] between the diamond of metal-bonded diamond goods grinding skin, referring to accompanying drawing 2, dotted line is represented the surface that metal-bonded diamond goods tyre body abrasion is preceding among the figure.The generation of pit can be quickened diamond [2] and normally go out sword, thereby sharper keen when making metal-bonded diamond goods grinding work piece.
Because the spheric granules [3] of equally distributed non-metallic composite material is contained in the diamond clear area in the metallic bond carcass [1] of the utility model self-sharpening metal-bonded diamond goods, when the grinding workpiece, after carcass [1] wearing and tearing, the non-metallic composite material spheric granules [3] on surface comes off and makes friction surface beans shape pit [6] occur from friction surface easily, referring to accompanying drawing 3, it makes friction surface easily reach the fatigue wear condition and quickens the wearing and tearing of carcass [1], thereby makes metal-bonded diamond goods " from sharp ".Simultaneously because the beans shape pit that occurs, only occur in the subrange of diamond clear area in the carcass [1], thus the non-structure homogeneous of metallic bond carcass [1] for diamond [2] to plate intensity effect very little.
The utility model self-sharpening metal-bonded diamond goods, its mechanical strength and anti-wear performance can satisfy the grinding performance demands simultaneously, the difficult problem that self-sharpening can differ from when solving the application of metal-bonded diamond goods, can with it make have the excellent grinding performance of high-quality grinding tool: the diamond saw blade that can make cutting stone material, solving the coping saw blade self-sharpening can be poor, the difficult problem of scaling loss stone material; Be used to make the diamond bit that on the rock of perpendicular hard fine and close easy, weak nonferromagnetic substance, to hole; Be used to make the metal-bonded diamond emery wheel, can when grinding work piece, can avoid taking place grinding and stop up the scaling loss workpiece, and can increase substantially the grinding roughness, to improve grinding efficiency; When being used in the bigger steel boring of the plasticity of cold rolling or hot rolling, hardness ag(e)ing can improve more than 50%.
The advantage of the utility model self-sharpening metal-bonded diamond goods is goods metallic bonds in grinding process The beans shape pit that the carcass surface occurs can impel the tired spot corrosion condition of the early stage realization in tyre body abrasion surface, improves therefrom carcass Wear rate improves the self-sharpening energy and don't affects carcass to adamantine retention, thereby can improve the diamond utilization rate, Improve grinding efficiency. Improve the service life of goods.
