The utility model content
The purpose of this utility model is the problem of mentioning in the above-mentioned background technology in order to solve, and a kind of round edge diamond-impregnated wheel is provided, and this round edge diamond-impregnated wheel has improved grinding efficiency greatly, has approximately reduced by the 40% pair of time that glass is processed.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of round edge diamond-impregnated wheel, comprise matrix, described matrix is the hollow cylinder shape, be surrounded by working lining on described matrix outer circumference surface, the described working lining outside along the circumferential direction offers the indent work nest, described indent work nest center radially offers into the water through hole, and described water inlet through hole connects described matrix and described working lining.
Further, described water inlet through hole is comprised of the through hole one in described working lining and the through hole two in described matrix.
Further, described through hole one is consistent with described through hole two connections and central shaft.
Preferably, described indent work nest cross section semicircular in shape.
Compared with prior art, the beneficial effects of the utility model are as follows:
the utility model is by the processing of punching bottom round edge diamond-impregnated wheel indent work nest, radially form the water inlet through hole in indent work nest center, this water inlet through hole is comprised of the through hole one in working lining and the through hole two in matrix, High Rotation Speed during emery wheel work, workpiece to be machined is carried out high-speed grinding, abrasive material and workpiece to be machined, bond and workpiece to be machined produce various complicated tribology phenomenons at its contact interface, produce the grinding heat of superelevation, if the grinding heat can not in time pass, will make the surface temperature of working lining too high, working lining is produced damage, thereby directly affect the working lining grinding performance, and then affect crudy and working (machining) efficiency.The utility model is provided with into the water through hole, this water inlet through hole connects matrix and working lining, form the radial passage, can produce centrifugal force during the emery wheel High Rotation Speed, cooling water is guided to the contact-making surface of emery wheel and workpiece to be machined by the radial passage, in time heat is taken away, avoided the excessive generation of heat, the burn workpiece has prevented effectively that grinding temperature is too high and the spark phenomenon that occurs, make emery wheel be difficult for passivation, be difficult for skidding, improved service life and the grinding efficiency of emery wheel.The utility model is also by reducing hardness and the density of bond, make the blunt of abrasive material and the abrasion of bond to mate, namely after the abrasive material blunt, the abrasion of bond are exposed new abrasive material, improved simultaneously the bonding strength between working lining and matrix, make the working lining that is consisted of by diamond abrasive and bond have stronger adhesive force, thereby be not prone to skidding, working lining also difficult drop-off in long-term use procedure.The utility model is by arranging the water inlet through hole, cooling water is introduced grinding area, in time the heat that produces in grinding process is taken away, simultaneously by reducing hardness and the density of bond, guarantee the synchronous wearing and tearing of diamond abrasive and bond, strengthen the tight ness rating of working lining and matrix, thereby be not prone to skidding, greatly improved service life and the grinding efficiency of emery wheel, approximately reduced by the 40% pair of time that glass is processed.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, during the below will describe embodiment, the accompanying drawing of required use is done to introduce simply, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the cutaway view of the utility model round edge diamond-impregnated wheel;
Fig. 2 is the partial sectional view after the punching of the utility model round edge diamond-impregnated wheel is processed;
Reference numeral: 1-working lining, 2-matrix, 3-through hole one, 4-through hole two.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with a kind of round edge diamond-impregnated wheel shown in Fig. 1-2, comprise matrix 2, matrix 2 is the hollow cylinder shape, be surrounded by working lining 1 on matrix 2 outer circumference surfaces, working lining 1 outside along the circumferential direction offers the indent work nest, indent work nest center radially offers into the water through hole, and the water inlet through hole connects matrix 2 and working lining 1.
Above-mentioned water inlet through hole is comprised of the through hole 24 in the through hole 1 in working lining 1 and matrix 2.
