Description
Technical field
The present invention relates to drill bit, more particularly to diamond bit.
Background technology
Diamond bit is mainly used in punching on the hard articles such as ceramics, glass, and the case hardness of these articles is higher,
Can not normally it be punched using common steel bit, because diamond bit hardness is higher than ceramics and glass, so can be
Punched on these hard articles.Existing ceramics, glass are bronze binding agent diamond with the working lining under diamond bit matrix
Layer, the diamond layer is in the presence of after beating a period of time, it is necessary to puts the first edge on a knife or a pair of scissors again, stock-removing efficiency is relatively low.
Therefore, existing Publication No. CN203281946U patent document discloses a kind of improved diamond drill bit, bag
Include bit matrix, the drill body bottom is provided with annular working layer, and the working lining is bronze binding agent diamond layer, institute
The thickness for stating diamond layer is 0.7mm or so, and the working lining bottom is additionally provided with water flowing chip removal fluting.
Diamond bit and diamond bit of the prior art in above-mentioned patent document, hold in boring procedure
Easily hot, still, for this case, the measure taken at present is to bore brill to stop, to reach radiating purpose.
The content of the invention
It is an object of the invention to provide a kind of diamond belt teeth drill bit, has good heat dispersion.
The present invention above-mentioned purpose technical scheme is that.
A kind of diamond belt teeth drill bit, including connector, circular tube shaped metallic matrix and the diamond bit being sequentially connected, institute
It is about 30mm to state metallic matrix length, and wall thickness is about 3mm, is about successively 5mm including length by connector position to diamond bit
First paragraph, length be about 20mm second segment and length be about the 3rd section of 5mm, wherein first paragraph, the 3rd section be hard
Alloy, wherein second segment include interior hard alloy layer, graphite linings and thickness that thickness is about 1.2mm successively from the inside to the outside
1.2mm outer hard alloy layer, wherein graphite linings close to connector position to close to diamond bit thickness by gradually increasing.
By using above-mentioned technical proposal, the wall thickness of metallic matrix is arranged to 3mm or so, much larger than routine 1.5mm,
So, graphite linings can be set inside metallic matrix；And metallic matrix is divided into three sections, wherein one close to diamond bit
Section needs enough intensity, therefore uses hard alloy, and the side heat production close to diamond bit is serious, it is therefore desirable to thickeies stone
Layer of ink, to ensure the intensity of whole metallic matrix, one section close to connector uses hard alloy.
Preferably：Multiple elongated through holes along metallic matrix length direction are opened on the surface of metallic matrix, multiple through holes exist
The uniformly arrangement of metallic matrix.
By using above-mentioned technical proposal, it using elongated through hole, both can be used as limbers, heat dispersion can be improved again
Preferably：The through hole length is about 15mm.
Preferably：Multiple grooves are equably placed with diamond bit, the groove number is identical with through hole；
Multiple grooves equably stagger with multiple through holes in the lateral cross section of metallic matrix.
By using above-mentioned technical proposal, because perforate or fluting can influence the bulk strength of drill bit, therefore by groove
Stagger with through hole, reduce perforate or the influence slotted to drill bit intensity.
Preferably：Multiple length along metallic matrix length direction are provided with the link position of metallic matrix and diamond bit
Shape groove, uniformly arrangement of multiple elongate slots in metallic matrix.
By using above-mentioned technical proposal, because diamond bit is substantially that diamond coatings are coated on into Metal Substrate body surface
Face and formed, therefore, to strengthen the stability that diamond coatings are fixed on after metal base surface, there is provided multiple elongated
Groove.
Preferably：It is fluted in the surface configuration that interior hard alloy layer contacts with graphite linings, in outer hard alloy layer and stone
The surface configuration of layer of ink contact is fluted.
By using above-mentioned technical proposal, because drill bit can generate heat in use, internal graphite linings are made to be heated swollen
Swollen, by groove, one provides the space of graphite linings expansion, avoids drill bit from deforming upon, two make the graphite linings after expansion
With bigger surface area, can preferably radiate.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Reference picture 1, a kind of diamond belt teeth drill bit, including connector 1, circular tube shaped metallic matrix 2 and the gold being sequentially connected
Diamond bit 3；Multiple elongated through holes 21 along the length direction of metallic matrix 2 are opened on the surface of metallic matrix 2, multiple through holes 21 exist
The uniformly arrangement of metallic matrix 2；Equably be placed with multiple grooves 31 on diamond bit 3, the number of groove 31 with
Through hole 21 is identical；Multiple grooves 31 equably stagger with multiple through holes 21 in the lateral cross section of metallic matrix 2.So, use
Elongated through hole 21, both can be used as limbers, can improve heat dispersion again；Further, since perforate or fluting can influence drill bit
Bulk strength, therefore groove 31 and through hole 21 are staggered, reduce perforate or the influence slotted to drill bit intensity.
Fig. 1 is referred again to, is provided with the link position of metallic matrix 2 and diamond bit 3 multiple along the length side of metallic matrix 2
To elongate slots 32, uniformly arrangement of multiple elongate slots 32 in metallic matrix 2.So, due to the essence of diamond bit 3
Diamond coatings are coated on the surface of metallic matrix 2 and formed, therefore, are fixed on metallic matrix to strengthen diamond coatings
Stability behind 2 surfaces, there is provided multiple elongate slots 32.
Reference picture 2 and Fig. 3, the length of metallic matrix 2 are about 30mm, including length be about 5mm first paragraph, length be about
20mm second segment and length is about the 3rd section of 5mm（First, second, third section is to mark in figs. 2 and 3）, wherein
First paragraph, the 3rd section be hard alloy, wherein second segment from the inside to the outside successively include thickness be about 1.2mm interior hard alloy
The outer hard alloy layer 24 that layer 22, graphite linings 23 and thickness are about 1.2mm, wherein graphite linings 23 by close to connector 1 to leaning on
Thickness gradually increases at nearly diamond bit.
So, the wall thickness of metallic matrix 2 is arranged to 3mm or so, so, can be in Metal Substrate much larger than the 1.5mm of routine
The inside of body 2 sets graphite linings 23；And metallic matrix 2 is divided into three sections, wherein one section close to diamond bit 3 needs enough
Intensity, therefore use hard alloy, the side heat production close to diamond bit 3 is serious, it is therefore desirable to thickeies graphite linings 23, is
Ensure the intensity of whole metallic matrix 2, one section close to connector 1 uses hard alloy.
This specific embodiment is only explanation of the invention, and it is not limitation of the present invention, people in the art
Member can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but as long as at this
All protected in the right of invention by Patent Law.
