Description
Technical field
The present invention relates to a kind of preparation method for being brazed sintered carbide tools and soldering sintered carbide toolses, belong to superhard material brazing skill
Art field.
Background technology
At present soldering sintered carbide tools as a kind of new sintered carbide tools progressively embody its in the application excellent
More performance is also had an optimistic view of by more and more enterprises, on the whole technological process Datong District of each enterprise's production soldering sintered carbide tools
Small difference.As soldering sintered carbide tools main raw material(s) --- metal powder solder, the general solder granularity used at present be
The mesh of 80 mesh~200, since the super hard abrasive granularity used in doctor portioned product is in 25~60#, so in the production process
It needs to be uniformly distributed with solder 3 times or even 6 times can be only achieved technological requirement, not only repeated work, be also easy to cause solder distribution thick
It spends uneven, very big influence is also resulted in the stability of product quality.
The content of the invention
It should it is an object of the invention to provide a kind of preparation method of the efficient soldering sintered carbide tools of cloth and use
Method soldering sintered carbide tools obtained.
In order to achieve the goal above, the technical solution of the preparation method of the soldering sintered carbide tools of the present invention is as follows：
A kind of preparation method for being brazed sintered carbide tools, including：Is formed on matrix by the first solder powder is uniformly distributed

The metal powder is made of two or more in copper, tin, nickel, silver, phosphorus, titanium, chromium.Further, metal powder
By any one in nickel, copper with any one in chromium, tin according to mass ratio 3:1 is mixed to get.
The soldering carries out under the atmosphere of argon gas or nitrogen, and the temperature of soldering is 960-1150 DEG C, the time of soldering
For 5-20min.Holding time is more preferably 10min.
The thickness of first solder powder is 0.05-0.2mm, and the thickness of second solder powder is 0.05-
0.2mm。
Described matrix surface scribbles glue-line, i.e., the gluing on matrix, and the first solder powder is sprinkling upon matrix surface completes
First solder powder is in the laying of matrix surface.Solder can be uniformly fixed to matrix surface by glue-line.
The technical solution of the soldering sintered carbide tools of the present invention is as follows：
A kind of soldering sintered carbide tools, is prepared using the above method.
The larger solder of particle is first dispensed in base by the preparation method of the soldering sintered carbide tools of the present invention by twice of cloth
Then body surface face dispenses the smaller solder of particle, little particle solder can so be made to easily enter the formation of bulky grain solder
In gap, solder distribution is more uniform, avoids and realizes being uniformly distributed for solder by multiple cloth in the prior art, reduces
Cloth number, improves production efficiency.Cloth number can be reduced to by the preparation method of the soldering sintered carbide tools of the present invention
Twice, cloth material process used time when monolithic instrument manufactures, 3min is reduced to by original 10min, single daily output product volume is by original
It is 30-35 pieces that the 17-20 pieces come, which increase, and production efficiency improves nearly 1 times, and due to the promotion of the solder cloth uniformity, makes
Product qualified rate is increased to 98% by original 85-90%, reduces the raw material since product qualified rate is low and brings and man-hour
Waste, reduce production cost.
