The diamond toothed drill bit has the advantage that indication can be provided for a worker when the temperature of the drill bit is excessively high.
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, and the case hardness of these article is higher.
The local temperature of the diamond bit of high speed rotating can more than 1000 degrees Celsius, but, work at such temperature, easily make broken drill, therefore, when using drill bit, staff must intermittently disable drill bit by rule of thumb, is continuing with after it leaves partial heat.If the operating experience of staff is not enough, it is easy for excessively using drill bit, is broken.
Summary of the invention
It is an object of the invention to provide a kind of diamond belt teeth drill bit, have temperature of diamond bit too high time can give staff's instruction.
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 the outer surface at described circular tube shaped metallic matrix embeds the indicator board of thermo-color material, described indicator board changeable colour under the environment of about 800 degrees Celsius；
Described indicator board is fixed on the outer surface of circular tube shaped metallic matrix by blend stop, and described blend stop is one-body molded with circular tube shaped metallic matrix.
By adopting technique scheme, when the temperature of drill bit raises, staff can be pointed out by indicator board, in order to avoid staff makes broken drill because of shortcoming operating experience, wherein, utilize blend stop that indicator board is fixed, there is good fixed effect, in use without departing from circular tube shaped metallic matrix.
Preferred: described metallic matrix length is about 30mm, wall thickness is about 3mm, included that length is about the first paragraph of 5mm, length is about the second segment of 20mm successively by connector position to diamond bit and length is about the 3rd section of 5mm, wherein first paragraph, the 3rd section be hard alloy, wherein second segment includes thickness from the inside to the outside successively and is about the outer hard alloy layer that the interior hard alloy layer of 1.2mm, graphite linings and thickness are about 1.2mm, and wherein graphite linings is gradually increased near diamond bit thickness by near connector position.
By adopting technique scheme, 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；And metallic matrix is divided into three sections, wherein need enough intensity near one section of diamond bit, therefore hard alloy is adopted, serious near the side heat production of diamond bit, it is thus desirable to thickening graphite linings, for ensureing the intensity of whole metallic matrix, near one section of employing hard alloy of union joint.
Preferred: 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, adopt elongated through hole, both can be used as limbers, heat dispersion can be improved again
Preferred: described through hole length is about 15mm.
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.

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 and Fig. 3, metallic matrix 2 length is about 30mm, be about the first paragraph of 5mm including length, length is about the second segment of 20mm and length is about the 3rd section (first, second, third section be mark in figs. 2 and 3) of 5mm, wherein first paragraph, the 3rd section be hard alloy, wherein second segment includes thickness from the inside to the outside successively and is about the outer hard alloy layer 24 that the interior hard alloy layer 22 of 1.2mm, graphite linings 23 and thickness are about 1.2mm, and wherein graphite linings 23 is gradually increased near diamond bit place thickness by near union joint 1.
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；And metallic matrix 2 is divided into three sections, wherein need enough intensity near one section of diamond bit 3, therefore hard alloy is adopted, serious near the side heat production of diamond bit 3, it is thus desirable to thicken graphite linings 23, for ensureing the intensity of whole metallic matrix 2, near one section of employing hard alloy of union joint 1.
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.
