Abstract
The utility model relates to a novel PCD grinding wheel. The problems that PCD blocks drop easily when PCD grinding wheels are used, and the PCD grinding wheels are low in welding strength and short in service lives and cause resource waste are effectively solved. The technical scheme is that the novel PCD grinding wheel comprises an open bowl-shaped steel substrate, the center of the bottom of the steel substrate is provided with a first through hole, the side of the steel substrate is provided with a plurality of second through holes distributed evenly circumferentially, the upper end of the steel substrate is provided with the upper surface extending out outwards around the outer edge surface of the upper surface, a plurality of staggered and circumferentially evenly distributed notches which form 15-degree inclination angles with the upper surface are respectively milled on the upper surface close to an inner ring and an outer ring, the notches are provided with matched silver soldering flakes, PCD blocks are welded to the silver soldering flakes and are formed by hard alloy bases and diamond layers sintered on the upper surfaces of the hard alloy bases, and the periphery of each PCD block is coated with a layer of copper. The novel PCD grinding wheel is ingenious in structure and low in invested cost, welding strength of the PCD grinding wheel is improved, the PCD blocks do not drop easily, the service life of the novel PCD grinding wheel is prolonged, resources are saved, and attractiveness is improved.
Description
Technical field
The utility model relates to emery wheel technical field, particularly relates to a kind of novel PC D emery wheel.
Background technology
High speed development along with modern science and technology, the grinding tool kind of superhard material is more come also many, its performance obtains development and raising, and PCD emery wheel has high abrasion, high tenacity, the lot of advantages such as height is heat-resisting, make PCD emery wheel more and more be subject to people's favor, PCD emery wheel in the market, PCD piece through silver soldering sheet, silver brazing solvent is directly welded in steel matrix, the PCD emery wheel weld strength being welded is like this low, resistance to corrosion is low, PCD piece easily comes off from steel matrix, once there be one or two PCD piece to come off, whole PCD emery wheel will be scrapped, caused the PCD emery wheel life-span to reduce, the wasting of resources.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of novel PC D emery wheel, effectively solved PCD emery wheel in use PCD piece easily come off, the problems such as PCD emery wheel weld strength is low, the life-span is short, resistance to corrosion is low, the wasting of resources.
The technical scheme of its solution is, the utility model comprises the bowl-shape steel matrix of opening, the center of steel matrix bottom is provided with the first through hole, steel matrix side is provided with a plurality of the second through holes that are circumference uniform distribution, steel matrix upper end is provided with around its outer edge surface and outwardly directed upper surface, upper surface is milled with respectively a plurality of interlaced that be circumference uniform distribution and be the notch at 15 degree inclinations angle with upper surface near inner ring and outer ring, notch is provided with identical silver soldering sheet, on silver soldering sheet, be welded with PCD piece, PCD piece consists of the diamond layer of carbide alloy pedestal and carbide alloy pedestal upper surface sintering, the surrounding of PCD piece is coated with layer of copper.
The utility model structure is ingenious, and input cost is low, has strengthened the weld strength of PCD emery wheel, and PCD piece difficult drop-off, has improved resistance to corrosion, has extended service life, has saved resource, has promoted attractive in appearance.

Fig. 2 is PCD emery wheel front view.
Fig. 3 is PCD emery wheel top view.
Fig. 4 is PCD piece front view.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
By Fig. 1 to Fig. 3, provided, the utility model comprises the bowl-shape steel matrix 1 of opening, the center of steel matrix 1 bottom is provided with the first through hole 2, steel matrix 1 side is provided with a plurality of the second through holes 3 that are circumference uniform distribution, steel matrix 1 upper end is provided with around its outer edge surface and outwardly directed upper surface 4, upper surface 4 is milled with respectively a plurality of interlaced that be circumference uniform distribution and be the notch at 15 degree inclinations angle with upper surface 4 near inner ring and outer ring, notch is provided with identical silver soldering sheet, on silver soldering sheet, be welded with PCD piece 5, PCD piece consists of the diamond layer 7 of carbide alloy pedestal 6 and carbide alloy pedestal 6 upper surface sintering, the surrounding of PCD piece is coated with layer of copper 8.
Described inner ring notch has 3, and outer ring notch has 3.
The second described through hole 3 has 4.
When the utility model is used, diamond layer 7 and a small amount of binding agent are sintered into PCD piece under superhigh-pressure high-temp, plated surface last layer copper 8 at PCD piece, increase PCD piece and steel matrix 1 weld strength and adhesive ability, make PCD piece be difficult for coming off from steel matrix 1, strengthened the resistance to corrosion of PCD emery wheel, improved wearability, then on the surface of steel matrix 1 notch, be coated with one deck silver brazing solvent, silver soldering sheet is put on notch, on silver soldering sheet, coat silver brazing solvent, PCD piece is placed on silver soldering sheet and starts to weld, the PCD emery wheel outward appearance that is coated with copper 8 is more attractive in appearance, difficult drop-off, improved wearability, increased the grinding intensity of PCD piece, extended PCD emery wheel service time, improved the life-span of PCD emery wheel, and silver-plated effect can be better, but silver-plated cost is very high, copper-plated effect is also fine, and greatly reduce cost, the second through hole 3 of PCD emery wheel side can be accelerated chip removal speed and drainage speed, and alleviated the weight of PCD emery wheel, the first through hole 2 of bottom is used for fixing PCD emery wheel, it is simple that this utility model seems, but the service life of PCD piece and grinding intensity affect the use of PCD emery wheel always, once there be one or two PCD piece to drop, cause whole PCD emery wheel to be scrapped, caused a large amount of wastings of resources, after this utility model plated with copper 8, can greatly improve weld strength and service life, saved ample resources.
The utility model structure is ingenious, and input cost is low, has strengthened the weld strength of PCD emery wheel, and PCD piece difficult drop-off, has improved resistance to corrosion, has extended service life, has saved resource, has promoted attractive in appearance.
