Now by as follows the label declaration in accompanying drawing: 1 is matrix, 2 is diamond layer, and 3 is tank, and 4 is bottom outlet, and 5 is framed, and 7 is graphite bar, and 8 is pressure head, and 9 is diamond layer in manufacturing.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
In preferred embodiment of the present invention, as shown in Figure 1 to Figure 3, the diamond tool of the specific embodiment of the invention, comprise matrix 1 and diamond layer 2, in matrix 1, have a through hole, tank 3 is set one on diamond layer 2 excircles, the width of tank 3 is no more than 1/10 of diamond layer 2 outer circumferences, the wide bond strength that affects diamond layer and matrix of anti-water stopping trough, also can allow diamond layer be utilized effectively.The degree of depth of tank 3 is no more than 1/2 of diamond layer 2 outside diameters, makes diamond tool little with the contact area of machined material in when work, in rotary course, to effectively grinding of machined material, there will not be leakage to grind position.The through hole of tank 3 and matrix 1 is parallel and communicate, and diamond layer 2 bottoms and matrix 1 junction arrange bottom outlet 4, and bottom outlet 4 is communicated with tank 3, can make cooling fluid pass into better in diamond layer tank from matrix bottom.Cooling fluid directly contacts with grinding face, has accelerated heat radiation, has avoided product to cause and burn, and also diamond tool has been played the effect of cooling protection, contributes to extend the service life of diamond tool.
The operation principle of diamond tool of the present invention is as follows: in working order time, the rotation of diamond tool generation circumference, the cooling fluid of diamond tool bottom can enter into rapidly diamond tool inside from limbers when rotated, and discharge from the cylindrical tank of diamond layer, take in time abrasive dust out of, meanwhile cooling fluid directly arrives Grinding Contact face, has taken away the amount of heat producing in grinding process, has improved grinding efficiency.
The manufacture method of diamond tool of the present invention is, adopt framed 5, pressure head 8 and graphite bar 7, first by matrix 1, framed 5 and graphite bar 7 assembling put together, drop into diamond forming powder and enter in cavity body of mould, then insert pressure head 8, make the moulding of diamond powder through high temperature pressurization, form diamond layer 9 in manufacture, and be consolidated with matrix 1, pressure head 8 and matrix 1 cylindrical match with framed 5 inner circles, and pressure head 8 inside grooves match with graphite bar 7 width; Compacting finishes to deviate from framed 5, more described pressure head 8 is taken out, and graphite bar 7 takes out, and makes described diamond tool.Wherein, framed 5, pressure head 8 and graphite bar 7 are to be all processed into by high-strength graphite, and matrix 1 is to be processed into by ordinary steel.
In manufacturing in the present invention diamond layer 9 and matrix 1 be direct high temperature exert pressure fixed together with, matrix 1 with manufacture in diamond layer 9 binding ends have 4 pointed tooths.Diamond layer 9 and matrix 1 combination in making to manufacture in the forming process of diamond layer increase consolidation strength simultaneously.
Therefore, diamond tool of the present invention, with limbers, cooling fluid enters from matrix base apertures, from diamond layer cylindrical tank, discharge, in continuous grinding process, can fully abrasive dust be discharged in time, to avoid obstruction and machined material surface produced to cut, and rapid heat dissipation, grinding efficiency is high, diamond layer is combined with matrix firmly, production process is simple to operate, cost-saving, the manufacture method of diamond tool of the present invention adopts diamond layer and the direct high temperature of matrix to exert pressure and is consolidated, in the forming process of diamond layer, make diamond layer and matrix combination simultaneously, can not make diamond layer post bake impaired, and bond strength is more firm.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
