Description
Technical field
The utility model belongs to diamond tool technical field, and in particular to one kind soldering diamond engraved stone knife.
Background technology
The high rigidity and desirable physical mechanical performance of diamond cause diamond tool becomes to process various stiff materials not
The effective tool that can lack.Diamond tool is commonly divided into plating, sintering and doctor by manufacture method and technique at present
Product, the diamond tool of various different process manufactures respectively have quality.
Plating diamond tool electroplating technology is simple, and it is easy to make, but on plating diamond tool electro-deposition coating gold
Belong to firm enhanced primary treatment is not present on the interface of abrasive material and tool matrix, abrasive material is simply coated on coating by machinery
Between matrix, therefore the coat of metal is small to the hold of diamond abrasive grain, is easy to peel off in flakes with coating because abrasive material comes off
Cause the global failure of emery wheel.
Sintered diamond tool is that pre-alloyed powder carcass and diamond particles mixing pressed compact sintering form, diamond cast
There is very high interface energy in pre-alloyed powder carcass, between diamond and common metal alloy, diamond particles cannot be
General low-melting alloy is infiltrated, bad adhesion.In traditional manufacturing technology, diamond particles produce after only being shunk by carcass
Mechanical clamping force be embedded in carcass Metal Substrate, without forming firm chemical bonded refractory or metallurgical binding, cause diamond
Particle is easily separated with carcass Metal Substrate at work, greatly reduces service life and the performance level of diamond tool.
Brazed diamond tool is that after heating, brazing filler metal melts, weldment is not by the use of the fusing point metal lower than mother metal as solder
Fusing, using liquid solder soak mother metal, fill play movement and with mother metal phase counterdiffusion, weldment is securely attached to one
Rise, although the diamond tool sharpness of soldering is higher, but service life is shorter, and existing soldering diamond is in rod iron
Upper molding cutter, abrasion resistance increases, but since blade surface only has one or two layers diamond, diamond is few, thickness
Too thin, cutter life is low, and especially bottom abrasion, which is faster than side, causes cutter to be scrapped.
Diamond engraved stone knife is brazed to be widely used by engraved stone industry, but there are a shortcoming, is exactly head
Welding is not firm enough, and easily graver head diamond is ground off, and diamond is not just sharp after grinding off, and stone material can be caused to burn existing
As and graver breaking phenomenon, and tool changing is pretty troublesome, it is necessary to knife on large-stone engraving machine, and every that knife outside diameter is thick
It is thin and different, so that the aesthetic effect of stone material pattern can be influenced.
For above technical problem, therefore need to make improvements.

Embodiment
Elaborate below in conjunction with the accompanying drawings to the utility model embodiment.
Embodiment：As shown in Figs. 1-2, a kind of soldering diamond engraved stone knife, including handle of a knife 1 and positioned at 1 lower end of handle of a knife,
Both sides are provided with the cutter head 2 of cutting edge；Cutter head 2 includes diamond side top layer 2-1 and diamond tool tip 2-2；1 end of handle of a knife is formed
There are the guide groove 1-1 being adapted with diamond tool tip 2-2, diamond tool tip 2-2 to be contained in guide groove 1-1, diamond
Side top layer 2-1 and diamond tool tip 2-2 are an integral molding structure, and cutter head 2 is formed to be overall using diamond sintering, so as to have
There is the effective working volume of bigger, improve cutting-tool's used life.
Gap 3 is left between 1 lateral wall of guide groove 1-1 and handle of a knife, the most most preferably scheme, the ultimate range in gap 3 are
0.34mm, by leaving gap 3 between guide groove and handle of a knife lateral wall, facilitates diamond tool tip 2-2 and guide groove 1-1
It is easy to process so that diamond tool tip 2-2 can preferably merge complementation with handle of a knife 1.
Diamond brazing layer 4, the diamond are both provided with the outside of diamond side top layer 2-1 and diamond tool tip 2-2
Brazing layer 4 is directly brazed on diamond side top layer 2-1 and diamond tool tip 2-2；Uniformly it is laid with diamond brazing layer 4
Some diamond particles, the diamond particles are in ordered arrangement form；The diamond particles of diamond brazing layer 4 are mainly distributed on
Surface, height of protrusion is high, and sharpness is good, and after diamond brazing layer 4 wears a part, still has sharp diamond
Particle residue, improves the sharpness of graver, and diamond brazing layer 4 is mainly distributed on the side of diamond side top layer 2-1
Smaller relative to end wear and side portion on the 2-2 of diamond tool tip, when engraving, pierces more smooth, avoids edge card
Firmly.
Diamond particles are in ordered arrangement form so that cutter is when in use, uniform on the basis of extremely strong aggregate chips excludes power
Stress and there is higher sharpness, tool life and high efficient grinding rate；Diamond brazing layer 4 is mainly used for enhancing gold
The sharpness of hard rock instrument, and the main of diamond is covered in one layer of top surface, and thickness can be achieved without too big, and cutter head 2 exists
Diamond brazing layer 4 can work on after wearing, and before diamond brazing layer 4 is completely worn out, diamond brazing layer 4
Remaining diamond particles can strengthen the sharpness of tool surfaces.
The height of diamond tool tip 2-2 is 2~6 with the thickness ratio of diamond side top layer 2-1:1, as most preferably square
Case, the height of diamond tool tip 2-2 are 3 with the thickness ratio of diamond side top layer 2-1:1, since graver is using process
In, the mainly cutting of diamond tool tip 2-2, therefore, the height of diamond tool tip 2-2 and the wear-resisting property phase of cutter head
Close, when its height is somewhat big, wear-resisting property also improves, the height of its diamond tool tip 2-2 is wear-resisting with side cut sword
Performance is related, sets the abrasion ratio of the suitable abrasion that highly can guarantee that 2 bottom of cutter head and cutting edge suitable, avoids the occurrence of and cut
When cutting sword and almost scrapping degree, diamond tool tip 2-2 also has longer life, extends making for soldering diamond engraved stone knife
Use the service life.
The height of diamond tool tip 2-2 is 8-30mm, and as most preferably scheme, the height of diamond tool tip 2-2 is
8.6mm, by using above-mentioned technical proposal, diamond exposure is higher, therefore the contact surface of diamond and machined material
Product increase, sharpness increase, so as to have good sharpness.
Diamond tool tip 2-2 is bulb, taper ball head or flat head；The handle of a knife 1 is three bone knobs, hexagonal handle or circle
Handle；By using above-mentioned technical proposal, diamond tool tip 2-2 can be used in diversified diamond graver, be fitted
It is wide with scope.
In order to improve the sharpness of diamond engraved stone knife, while ensure the intensity of cutter head 2, avoid because it is too thin and caused by
Fracture, and facilitate exerting oneself for graver, diamond side top layer 2-1 and the angle of 1 center line of handle of a knife are 8 °~75 °, specifically used
When, it can customize angle according to different and engraving technology, such as 10 °, 20 °, 30 °, 40 °, 50 °, 60 °.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model；Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
Although reference numeral in figure is used more herein：Handle of a knife 1, guide groove 1-1, cutter head 2, diamond side top layer 2-
1, diamond tool tip 2-2, gap 3, the grade term of diamond brazing layer 4, but it does not preclude the possibility of using other terms.Make
It is used for the purpose of more easily describing and explaining the essence of the utility model with these terms；It is attached to be construed as any type
