Description
Technical field
The present invention relates to drill bit, particularly to diamond bit.
Background technology
Diamond bit is mainly used on the hard article such as pottery, glass to punch, the case hardness of these article is higher, common steel bit is adopted to punch normally, owing to diamond bit hardness ratio pottery and glass are high, so can punch on these hard articles. Working lining under existing pottery, glass diamond bit matrix is bronze binding agent diamond layer, after a period of time is beaten in the existence of this diamond layer, it is necessary to again putting the first edge on a knife or a pair of scissors, stock-removing efficiency is relatively low.
For this, the patent documentation that existing publication number is CN203281946U discloses a kind of improved diamond drill bit, including bit matrix, described drill body bottom is provided with annular working layer, described working lining is bronze binding agent diamond layer, the thickness of described diamond layer is about 0.7mm, and described working lining bottom is additionally provided with water flowing chip removal fluting.
The above-mentioned diamond bit in patent documentation and diamond bit of the prior art, easily hot in boring procedure, but, for this situation, the measure taked at present is to bore brill to stop, to reach heat radiation purpose.
Summary of the invention
It is an object of the invention to provide a kind of diamond belt teeth drill bit, there is good heat dispersion.
The above-mentioned purpose of the present invention technical scheme is that.
A kind of diamond belt teeth drill bit, including the union joint being sequentially connected with, circular tube shaped metallic matrix and diamond bit, it is characterized in that described metallic matrix wall thickness is about 3mm, include thickness to be from the inside to the outside successively the interior hard alloy layer of 1.2mm, thickness be the graphite linings of 0.6mm and outer hard alloy layer that thickness is 1.2mm;
Open multiple elongated through hole along metallic matrix length direction on the surface of metallic matrix, multiple through holes are in the uniformly arrangement of metallic matrix.
By adopting technique scheme, on the one hand, the wall thickness of metallic matrix is arranged to about 3mm, much larger than conventional 1.5mm, so, graphite linings can be set inside metallic matrix; It addition, adopt the inside and outside hard alloy layer being about 1.2mm, it is ensured that enough intensity. On the other hand, adopt elongated through hole, both can be used as limbers, heat dispersion can be improved again.
Preferred: described metallic matrix length is about 30mm, and external diameter is about 24mm; Described through hole length is about 15mm, and width is about 5mm.
By adopting technique scheme, the length ratio of metallic matrix Yu through hole being set to 2, the intensity institute after perforate making metallic matrix is impacted little.
Preferred: being placed with multiple groove on diamond bit equably, described groove number is identical with through hole;
Multiple grooves and multiple through holes stagger equably in the lateral cross section of metallic matrix.
By adopting technique scheme, owing to perforate or fluting can affect the bulk strength of drill bit, therefore groove and through hole are staggered, make perforate or fluting that the impact of drill bit intensity to be reduced.
Preferred: the link position at metallic matrix Yu diamond bit is provided with multiple elongate slots along metallic matrix length direction, and multiple elongate slots are in the uniformly arrangement of metallic matrix.
By adopting technique scheme, due to diamond bit essence, diamond coatings is coated metal base surface and formed, therefore, for strengthening the stability after diamond coatings is fixed on metal base surface, be provided with multiple elongate slots.
Preferred: the surface configuration contacted with graphite linings at interior hard alloy layer is fluted, the surface configuration that hard alloy layer contacts with graphite linings outside is fluted.
By adopting technique scheme, owing to drill bit in use can generate heat, make the graphite linings expanded by heating of inside, by groove, one provides the space that graphite linings expands, it is to avoid drill bit deforms upon, two make expansion after graphite linings there is bigger surface area, can dispel the heat better.

Fig. 3 is the A portion enlarged drawing in Fig. 2.
In figure, 1, union joint; 2, metallic matrix; 21, through hole; 22, interior hard alloy layer; 221, groove; 23, graphite linings; 24, outer hard alloy layer; 241, groove; 3, diamond bit; 31, groove; 32, elongate slots.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
With reference to Fig. 1, a kind of diamond belt teeth drill bit, including the union joint 1 being sequentially connected with, circular tube shaped metallic matrix 2 and diamond bit 3; Open multiple elongated through hole 21 along metallic matrix 2 length direction on the surface of metallic matrix 2, multiple through holes 21 are in the uniformly arrangement of metallic matrix 2; Being placed with multiple groove 31 on diamond bit 3 equably, groove 31 number is identical with through hole 21; Multiple grooves 31 stagger in the lateral cross section of metallic matrix 2 equably with multiple through holes 21. So, adopt elongated through hole 21, both can be used as limbers, heat dispersion can be improved again; Further, since perforate or fluting can affect the bulk strength of drill bit, therefore groove 31 and through hole 21 are staggered, make perforate or fluting that the impact of drill bit intensity to be reduced.
Referring again to Fig. 1, the link position at metallic matrix 2 with diamond bit 3 is provided with multiple elongate slots 32 along metallic matrix 2 length direction, and multiple elongate slots 32 are in the uniformly arrangement of metallic matrix 2. So, due to diamond bit 3 essence, diamond coatings is coated metallic matrix 2 surface and formed, therefore, for strengthening the stability after diamond coatings is fixed on metallic matrix 2 surface, be provided with multiple elongate slots 32.
With reference to Fig. 2, metallic matrix 2 wall thickness is about 3mm, includes thickness to be from the inside to the outside successively the interior hard alloy layer 22 of 1.2mm, thickness be the graphite linings 23 of 0.6mm and outer hard alloy layer 24 that thickness is 1.2mm. So, the wall thickness of metallic matrix 2 is arranged to about 3mm, much larger than conventional 1.5mm, so, graphite linings 23 can be set inside metallic matrix 2; It addition, adopt the inside and outside hard alloy layer 24 being about 1.2mm, it is ensured that enough intensity.
With reference to Fig. 3, at interior hard alloy layer 22 fluted with the surface configuration that graphite linings 23 contacts 221, hard alloy layer 24 fluted with the surface configuration that graphite linings 23 contacts 241 outside. So, owing to drill bit in use can generate heat, make graphite linings 23 expanded by heating of inside, by groove 221,241, one provides the space that graphite linings 23 expands, it is to avoid drill bit deforms upon, two make expansion after graphite linings 23 there is bigger surface area, can dispel the heat better.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in scope of the presently claimed invention.
