Description
The application be application No. is：201610203872.7 the applying date：It is on 03 31st, 2016, entitled " a kind of
The divisional application of the patent of invention of diamond belt teeth drill bit ".
Technical field
The present invention relates to drill bits, more particularly to diamond bit.
Background technology
Diamond bit is mainly used for punching on the hard articles such as ceramics, glass, and the case hardness of these articles is relatively high.
The local temperature of high-speed rotating diamond bit can be more than 1000 degrees Celsius, still, the work at such temperature
Make, be easy to make broken drill, therefore, when using drill bit, staff must intermittently deactivate drill bit by rule of thumb, wait for that it is dissipated
It is continuing with after removing partial heat.If the operating experience of staff is insufficient, it is easy for excessively using drill bit, is broken.
Invention content
The purpose of the present invention is to provide a kind of diamond belt teeth drill bits, can give work people when excessively high with temperature of diamond bit
Member's instruction.
The present invention above-mentioned purpose technical scheme is that.
A kind of diamond belt teeth drill bit, including sequentially connected connector, circular tube shaped metallic matrix and diamond bit,
It is characterized in that being embedded in the indicator board of thermo-color material in the outer surface of the circular tube shaped metallic matrix, the indicator board is about 800
Changeable colour in the environment of degree Celsius；
The indicator board is fixed on the outer surface of circular tube shaped metallic matrix, the blend stop and circular tube shaped Metal Substrate by blend stop
Body by integral forming.
Staff can be prompted by indicator board when the temperature of drill bit increases by using above-mentioned technical proposal, with
Exempt from staff because shortcoming operating experience makes broken drill, wherein be fixed, have good solid to indicator board using blend stop
Effect is determined, in use without departing from circular tube shaped metallic matrix.
Preferably：The metallic matrix length is about 30mm, and wall thickness is about 3mm, by connector position to diamond bit according to
The third section that the second segment and length that the secondary first segment for being about 5mm including length, length are about 20mm are about 5mm, wherein first
Section, third section be hard alloy, wherein second segment from the inside to the outside successively include thickness be about 1.2mm interior hard alloy layer,
The outer hard alloy layer that graphite linings and thickness are about 1.2mm, wherein graphite linings are by close to connector position to close diamond bit
Thickness gradually increases.
By using above-mentioned technical proposal, the wall thickness of metallic matrix is arranged to 3mm or so, is much larger than conventional 1.5mm,
In this way, graphite linings can be arranged inside metallic matrix；And metallic matrix is divided into three sections, wherein close to the one of 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 thicken stone
Layer of ink, to ensure the intensity of entire 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.
Limbers not only can be used as, but also can improve heat dissipation performance using elongated through-hole by using above-mentioned technical proposal.
Preferably：The through-hole length is about 15mm.
Preferably：Multiple straight slots are equably placed on diamond bit, the straight slot number is the same as through hole；
Multiple straight slots are equably staggered with multiple through-holes in the lateral cross section of metallic matrix.
By using above-mentioned technical proposal, since trepanning or fluting can influence the integral strength of drill bit, by straight slot
It is staggered with through-hole, trepanning or the influence slotted to drill bit intensity is made to reduce.
Preferably：It is equipped with multiple length along metallic matrix length direction in the link position of metallic matrix and diamond bit
Shape slot, uniformly arrangement of multiple elongate slots in metallic matrix.
By using above-mentioned technical proposal, since diamond bit is substantially that diamond coatings are coated on Metal Substrate body surface
Face and formed, therefore, be fixed on the stability after metal base surface to reinforce diamond coatings, be provided with multiple elongated
Slot.

Specific implementation mode
Below in conjunction with attached drawing, invention is further described in detail.
Referring to Fig.1, a kind of diamond belt teeth drill bit, including sequentially connected connector 1, circular tube shaped metallic matrix 2 and gold
Hard rock drill bit 3；Multiple elongated through-holes 21 along 2 length direction of metallic matrix 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 straight slots 31 on diamond bit 3,31 number of straight slot with
Through-hole 21 is identical；Multiple straight slots 31 are equably staggered with multiple through-holes 21 in the lateral cross section of metallic matrix 2.In this way, using
Elongated through-hole 21 not only can be used as limbers, but also can improve heat dissipation performance；In addition, since trepanning or fluting can influence drill bit
Integral strength, therefore straight slot 31 and through-hole 21 are staggered, so that trepanning or the influence slotted to drill bit intensity is reduced.
Fig. 1 is referred again to, is equipped in the link position of metallic matrix 2 and diamond bit 3 multiple along 2 length side of metallic matrix
To elongate slots 32, uniformly arrangement of the multiple elongate slots 32 in metallic matrix 2.In this way, due to 3 essence of diamond bit
Diamond coatings are coated on 2 surface of metallic matrix and are formed, therefore, are fixed on metallic matrix to reinforce diamond coatings
Stability behind 2 surfaces is provided with multiple elongate slots 32.
With reference to Fig. 2 and Fig. 3,2 length of metallic matrix is about 30mm, including length be about 5mm first segment, length be about
The third section (first, second, third section is to mark in figure 2 and figure 3) that the second segment and length of 20mm is about 5mm, wherein
First segment, third section are hard alloy, and wherein second segment is about successively from the inside to the outside including thickness
The outer hard alloy layer 24 that interior hard alloy layer 22, graphite linings 23 and the thickness of 1.2mm is about 1.2mm, wherein stone
Layer of ink 23 close to connector 1 to close to thickness at diamond bit by gradually increasing.
In this way, the wall thickness of metallic matrix 2 is arranged to 3mm or so, much larger than conventional 1.5mm, in this way, can be in Metal Substrate
Graphite linings 23 are arranged in 2 inside of body；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 thicken graphite linings 23, be
Ensure the intensity of entire metallic matrix 2, one section close to connector 1 uses hard alloy.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, people in the art
Member can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as at this
It is all protected by Patent Law in the right of invention.
