Technical field
The invention belongs to diamond tool technical fields, and in particular to a kind of diamond saw blade and diamond saw blade and
Its production method.
Background technique
Diamond saw blade is by disc matrix and to be connected to the diamond segment of matrix outer rim and constitute, and has been widely used
In the cutting of nonmetallic materials, it is primarily adapted for use in trimming and cutting in glass and ceramics, due to Glass breadks easily, therefore is wanted
Saw blade is asked to want thin；And ceramic hardness is high, therefore require saw blade that there is good cutting ability；In field of stone processing, diamond saw
Piece using extremely wide, generally have monolithic diamond saw and combined diamond saw, although monolithic sawing efficiency is compared with combination saw
It is lower, but its application is also relatively broad, especially in trimming, is sawed using monolithic more quick.Although combination saw cutting efficiency
It is higher, but it is relatively low to the sharpness requirement of monolithic saw blade.
Diamond saw blade has many advantages, such as that hardness is high, wearability is good, and main problem existing for diamond saw blade is at present:
Saw blade tip is gradually worn out in cutting process, causes cutter head sharpness to decline, while the heat quickly generated during the cutting process
It will cause too fast be heated of diamond and cause to damage.
The wearability of diamond saw blade also has larger impact to stock-removing efficiency, if metal alloy wearability is excessively high, is easy to lead
It causes diamond exposure to influence height of protrusion slowly excessively, if metal alloy wearability is poor, is easy during the cutting process to saw bit matrix
It causes to damage.Clast is generated in cutting process simultaneously, is easy that saw blade tip surface is caused to wear, and is influenced cutter head and is used the longevity
Life.
It therefore, is very necessary to the research of diamond saw blade and its cutter head.
Summary of the invention
The purpose of the present invention is to solve the deficiencies in the prior art, and provide a kind of diamond saw blade and diamond
Saw blade and preparation method thereof, the diamond saw blade have excellent sharpness and wearability, and cutter head long service life guarantees
The cutting efficiency and service life of diamond saw blade.
The present invention adopts the following technical scheme:

Cold pressing: step 2 the load weighted leading portion material of step 1, middle section material and back segment material is cold-pressed into after mixing respectively
Piece obtains leading portion tabletting, middle section tabletting and back segment tabletting；
Hot pressed sintering: leading portion tabletting, middle section tabletting and back segment tabletting are sequentially placed into hot pressing in hot pressing die and burnt by step 3
It becames one to get the diamond saw blade.
Further, pressure when being cold-pressed described in step 2 is 190-205kg/cm2。
Further, the pressure described in step 3 when hot pressed sintering is 200-220kg/cm2, temperature 800-1000
DEG C, sintering time 3-10min.
With the method for diamond saw blade production diamond saw blade, steps are as follows:
Step 1: blasting guardrail is prepared, blasting guardrail is placed in abrasive blast equipment；
Step 2: diamond saw blade surface is cleared up, and blasting guardrail described in step 1 is sprayed to diamond saw
Piece bit interface；
Step 3: by the diamond saw blade obtained by step 2 Jing Guo blasting treatment be soldered on saw bit matrix to get
The diamond saw blade.
Further, blasting guardrail described in step 1 according to the following component of mass percent meter by being made: silicon carbide
92-97%, antirust agent 2-7%, odium stearate 0.6-0.9%, neopelex 0.1-0.3%, the sum of each component are total
It is calculated as 100%.
Further, the production method of the blasting guardrail are as follows: according to the proportion, by silicon carbide, antirust agent, stearic acid
Sodium and neopelex be mixed evenly to get.
Compared with prior art, the present invention has the advantages that:
First, the present invention studies the materials of diamond saw blade, three sections before, during and after its raw material is divided into
There is some difference for the raw material proportioning of material, middle section material and front and back section material, effectively prevents in cutting process due to cutter head two sides
Cutter head sharpness declines caused by abrasion is excessive；It joined silver powder in cutter head raw material, effectively increase the thermal diffusivity of cutter head,
Cutting process thermal damage caused by diamond can be reduced, the service life of cutter head is improved；
Second, the present invention has carried out rational modification to the raw material of diamond saw blade, improves metal alloy and Buddha's warrior attendant
The consistency of stone mill damage ensure that diamond goes out sword speed and height of protrusion in cutting process, provide cutting efficiency；
Third, the present invention have carried out blasting treatment in bit interface, increase the wearability and service life of cutter head entirety,
Avoid the clast generated in cutting process abrasion caused by bit interface；Improvement to blasting guardrail, not only increases sandblasting
Expect the adhesive force on cutting insert substrate surface, further improves the mobility of blasting guardrail, ensure that the continuous-stable of grit blasting operation.
