The invention discloses a kind of diamond belt teeth drill bit, including the connector, circular tube shaped metallic matrix and diamond bit being sequentially connected, the indicator board of thermo-color material, indicator board changeable colour in the environment of 800 degrees Celsius are embedded in the outer surface of the circular tube shaped metallic matrix；The indicator board is fixed on the outer surface of circular tube shaped metallic matrix by blend stop, and the blend stop is integrally formed with circular tube shaped metallic matrix.A kind of diamond belt teeth drill bit provided by the invention, staff's instruction can be given when having temperature of diamond bit too high.
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.
The local temperature of the diamond bit of rotation can be more than 1000 degrees Celsius, still at a high speed, the work at such temperature
Make, easily make broken drill, therefore, when using drill bit, staff must intermittently disable drill bit by rule of thumb, treat that it dissipates
It is continuing with after removing partial heat.If the operating experience deficiency of staff, is easy for excessively using drill bit, is broken.
The content of the invention
It is an object of the invention to provide a kind of diamond belt teeth drill bit, can give work people when having temperature of diamond bit too high
Member's instruction.
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, its
It is characterised by 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 taken the photograph 800
Changeable colour in the environment of family name's degree；
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.
By using above-mentioned technical proposal, when the temperature rise of drill bit, staff can be prompted by indicator board, with
Exempt from staff because shortcoming operating experience makes broken drill, wherein, indicator board is fixed using blend stop, there is good consolidate
Effect is determined, in use without departing from circular tube shaped metallic matrix.
Preferably：The metallic matrix length is 30mm, wall thickness 3mm, is wrapped successively by connector position to diamond bit
Include the second segment that first paragraph, length that length is 5mm are 20mm and the 3rd section that length is 5mm, wherein first paragraph, the 3rd section
For hard alloy, interior hard alloy layer, graphite linings and the thickness that wherein second segment is successively from the inside to the outside 1.2mm including thickness are
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 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.
Brief description of the drawings

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 30mm, including length be 5mm first paragraph, that length is 20mm
Two sections and length are the 3rd section of 5mm（First, second, third section is to mark in figs. 2 and 3）, wherein first paragraph, the 3rd
It is 1.2mm interior hard alloy layer 22, graphite linings 23 that Duan Junwei hard alloy, wherein second segment include thickness successively from the inside to the outside
With the outer hard alloy layer 24 that thickness is 1.2mm, wherein graphite linings 23 are by the thickness at connector 1 to close diamond bit
Gradually increase.
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.
