Description
Technical field
The present invention relates to saw blade field more particularly to it is a kind of for precision casting automation cutting diamond saw blade and its
Production method.
Background technique
Space flight and auto parts and components largely use the alloy precisions casting such as 20NiCrMo.Such casting mostly uses townhouse to cast greatly
It makes, after the completion of casting, needs to carry out cutting separation.Traditional approach cuts alloy precision casting using resin cutting slice.
Resin cutting slice is made of corundum, and structural strength is not high, and easy disintegrating tablet causes danger, while manufacturing and belonging to high energy consumption, in use
Consumption is huge, labor intensity of workers is big, dust pollution is serious, damage workers ' health.For protection Employee Security and improve work
Efficiency, massive casting enterprise gradually starts using automation cutting machine, but resin cutting slice is for setting when automating cutting bed
Rouge cutting sheet is lost faster, will shut down replacement within every three minutes, the serious performance for limiting automation equipment performance.
The prior art mainly uses 30/35 mesh diamond to carry out cutting operation to common casting, for the weldering for ensureing diamond
Intensity is connect, often bonding agent will form the package to diamond particles.This technology mode does not ask the processing of hard brittle metal
Topic, and it is able to ascend saw life, but when processing stickiness metal (such as largely using the accurate casting of 20NiCrMo alloy
Part), molten metal can be covered on diamond surface, shell membrane shape be formed, so that diamond be made to fail.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provide that a kind of chip space is big, it is automatic to can be used for accurate stickiness casting
The diamond saw blade and its production method for changing cutting, solve existing diamond saw blade and occur viscous knife when cutting casting, can not
The problem of cutting adherent metal.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of diamond saw blade for precision casting automation cutting, including matrix, the edge of matrix are provided with several
The edge soldering of key chain chip space and several M tooth sockets, key chain chip space and the setting of M septum interalveolare, matrix has several Buddha's warrior attendants
Stone, the grain graininess of diamond are 20/25 mesh；Bonding agent between diamond and matrix is 40/60+60/80+80/120 mesh.
As a preferred solution of the present invention, cloth ratio of the diamond on matrix is 1:(1.8-2).
As a preferred solution of the present invention, the material of described matrix is 65Mn.
As a preferred solution of the present invention, described matrix with a thickness of 2.9 ㎜.
As a preferred solution of the present invention, it is provided in described matrix for being installed in automation casting cutting machine
Heart hole and several counter sinks.
As a preferred solution of the present invention, two circle heat release hole of described matrix periphery setting.
A kind of diamond saw blade production method for precision casting automation cutting, includes the following steps:
A) several key chain chip spaces and several M tooth sockets are cut at the edge of matrix, between key chain chip space and M tooth socket
Every setting；
B) selecting granularity is the diamond of 20/25 mesh, by diamond brazing in the edge of matrix, is brazed used combine
Agent is 40/60+60/80+80/120 mesh, and is disposably added；Wherein at 1033 DEG C, soaking time is for brazing temperature control
20min。
Compared with prior art, the beneficial effects of the present invention are:
1, the diamond particles granularity of diamond saw blade of the invention is 20/25 mesh, compared to conventional for cutting gold
The granularity of the saw blade of category, diamond is bigger.Bonding agent between diamond and matrix is 40/60+60/80+80/120 mesh, and
Disposable addition, thus the reduction of bonding agent, so that diamond exposure degree is improved.Selection and knot by diamond grit
The adjustment of mixture, chip space increase 6-8 times, and the increase of chip space is conducive to continue cutting sticky stuff, automates simultaneously
The stickiness metal that the high revolving speed of cutting machine is also beneficial to cut is got rid of.The edge of matrix is provided with several key chain chip spaces
With several M tooth sockets, key chain chip space and the setting of M septum interalveolare, the chip removal ability of diamond saw blade are improved, and impurity is avoided to cover
With diamond surface, diamond is further increased to the lasting cutting power of adherent metal.
By above-mentioned improvement, diamond saw blade can give full play to the superhard characteristic of diamond and the property of automatic cutting board
Energy advantage, can undertake the high revolving speed of 105m/s, and durable, be 60 times or more of conventional resins cutting sheet service life, performance
Superior, comprehensive cost performance is prominent.Meanwhile big granularity, being higher by that sword degree diamond wear proof is good, and chip space is big, it can be with maximum limit
The extension saw blade lifetime of degree, while reducing the occurrence of sticking knife.
2, cloth of the diamond on matrix is than being increased to 1:(1.8-2 from the 1:1.5 of conventional saw blade), improve diamond saw
The cutting power of piece.
3, the material of matrix is 65Mn, and the strength and toughness of diamond saw blade correspondinglys increase.
4, it is 2.9mm that matrix thickness is increased by 2.5mm, ensures saw blade intensity.
5, matrix is connected on automation casting cutting machine by centre bore and several counter sinks, guarantees the reliable of installation
Property, avoid saw blade unstable situation when only installing by centre bore.
6, setting two circle heat release hole in matrix periphery can be diamond saw blade and effectively radiate.
7, in production method of the invention, the diamond particles granularity of diamond saw blade is 20/25 mesh, compared to routine
For cutting the saw blade of metal, the granularity of diamond is bigger.Bonding agent between diamond and matrix is 40/60+60/80+
80/120 mesh, and disposably add, thus the reduction of bonding agent, so that diamond exposure degree is improved.Pass through diamond grain
The selection of degree and the adjustment of bonding agent, chip space increase 6-8 times, and the increase of chip space is conducive to continue cutting stickiness material
Material, while the stickiness metal that the high revolving speed for automating cutting machine is also beneficial to cut is got rid of.If the edge of matrix is provided with
Dry key chain chip space and several M tooth sockets, key chain chip space and the setting of M septum interalveolare, the chip removal ability of diamond saw blade mention
Height avoids impurity covering and diamond surface, further increases diamond to the lasting cutting power of adherent metal.
Using bulky grain, high-strength diamond, while reducing bonding agent on the one hand can to increase cutting nichrome etc. glutinous
The chip space of property material, on the other hand will cause difficult point to the weld strength of diamond, it is therefore necessary to soldering processes into
Row adjustment.Therefore, welding temperature is promoted to 1033 ° by 1023 °, soaking time was reduced to 20 minutes by 30 minutes, to guarantee
Use the weld strength in the case of bulky diamond and reduction bonding agent.High-strength diamond keeps lesser heat at high temperature
Damage, then temperature raising will not cause excessive influence to diamond.
By above-mentioned improvement, diamond saw blade can give full play to the superhard characteristic of diamond and the property of automatic cutting board
Energy advantage, can undertake the high revolving speed of 105m/s, and durable, be 60 times or more of conventional resins cutting sheet service life, performance
Superior, comprehensive cost performance is prominent.Meanwhile big granularity, being higher by that sword degree diamond wear proof is good, and chip space is big, it can be with maximum limit
The extension saw blade lifetime of degree, while reducing the occurrence of sticking knife.
