Abstract
A preparation method for a cutting tool composite is provided. The method comprises the following steps that TiCuNi alloy with the Ti content being 25-65% is selected from fe, Ni and Co, crushed and then stirred with Al powder, and a plate metal binding agent is formed through extrusion; a graphite material is manufactured into a hollow cylindrical heating block, the plate metal binding agent is placed to the bottom of the heating block, and then cubic boron nitride powder is poured into the heating block; and the heating block loaded with the metal binding agent and the cubic boron nitride powder is placed in a high-temperature and high-pressure device, pressurizing is conducted successively to make the pressure reach 35 kPa, the temperature of the heating bock is increased until the metal binding agent is fused, and after normal cooling, the cutting tool composite can be obtained.
Description
Technical field
The invention belongs to field of compound material, more particularly to a kind of preparation method of cutlery composite.
Background technology
Machinery manufacturing industry is occupied in whole national economy and its consequence, and metal cutting process is in manufacturing industry
Occupy leading position.In machining, raising working (machining) efficiency is had with workpiece surface quality using cutting fluid important
Effect, but be also maximum polluter.Cutting fluid can be caused to environment in manufacture, each period for using, processing and discharge
Severe contamination.Constantly strengthen the modern times that environmentally safe, sustainable development how are found under main trend in global environmental consciousness
Manufacturing mode has become the most urgent difficult problem that China's manufacturing industry faces.
The species of cutlery material has much at present, and the conventional tool steel that has (includes carbon tool steel, alloy tool steel and height
Fast steel), hard alloy, ceramics, diamond (natural and artificial) and cubic boron nitride etc..Carbon tool steel and alloy tool steel,
Because its thermostability is very poor, hand toolss are currently only used for.By understanding, existing cutlery material mainly by by several gold
The method of category material mixing heating, the cutlery for being prepared obtaining have the shortcomings that easy to wear, short life in use.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of composite so that what is prepared is compound
Material possesses anti abrasive advantage.
To solve above-mentioned technical problem, the invention provides a kind of preparation method of composite：The method includes following
Step：
First, the TiCuNi alloys that Ti contents are divided into 25-65% are chosen from fe, Ni, CO, by the TiCuNi alloyed powders
Stir with Al powder after broken, be squeezed into plates metal adhesive；
Secondly, a hollow cylinder heat block is made with graphite material, the plates metal adhesive is put into into heating
Block bottom, then cubic boron nitride powder is injected in heat block.
By the above-mentioned heat block equipped with metal adhesive and cubic boron nitride powder, it is put in high temperature high pressure device, successively
Pressurization, makes pressure reach 35 kPas so as to heat up, until metal adhesive, after normal cooling, you can obtain of the present invention
Cutlery composite.
Further, TiCuFe alloys account for the 60-70% of gross mass, and the content of Al powder accounts for 10-20%.
Further, the quality of cubic boron nitride powder is 5-7 times of metal adhesive quality.
In terms of existing technologies, the cutlery that the present invention is produced in cutting quenching hardness is embodiment of the present invention
During the steel part of 60HRC, in the case of 50 ms/min of linear velocity, the life-span up to 80 minutes, yield rate 65%-80%.
