Description
Technical field
The present invention relates to machining technology field, especially a kind of grinding method for grinding cemented carbide powder powder material.
Background technology
At present, it is still to be ground with ball mill for grinding the method for cemented carbide powder powder material that the country is existing, and is made
With the grinding drum of ball mill be still made of stainless steel material, hardness is relatively low, and wearability is poor, in grinding cemented carbide powder
During material so that the inner barrel wall part of ball mill is easily worn and torn, the service life of ball mill is influenceed；Meanwhile, when inner barrel wall weares and teares
The powder of stainless steel for falling, is doped into hard alloy powder, reduces the purity of hard alloy powder, significantly impacts powder
Processing performance.
And, the grinding drum inner barrel wall of existing stirring ball mill is cylindrical surface structure, when grinding is rotated, due to
Mixing drum inwall is smooth, cylindrical peripheral surface, and alloy powder grinds in the effect of centrifugal force, uneven dispersion on the whole face of cylinder
Ball is small with the contact surface of mixing drum inwall, and powder is difficult to aggregation grinding, and this structure can cause alloyed powder abrasive lapping efficiency low,
And the effect of grinding is poor, generally by grinding to reach a good grinding effect for a long time, reduces indirectly
The service life of ball mill.
The content of the invention
Problem to be solved by this invention is to provide a kind of efficient, reliability, can be good at ensureing hard alloy powder again
The grinding method of processing performance.
In order to solve the above problems, the technical scheme is that：The grinding method of this hard alloy powder is：By hard
After alloy powder raw material is sufficiently mixed, feeding hard alloy agitating ball mill is ground；The hard alloy agitating ball mill
Mixing drum and rotating shaft and mixing arm on support body are included, the rotating shaft is connected with actuating unit and engine,
It is provided with the mixing drum inwall and also has more than 1 mill ball in the grommet of multiple unitary circulars, mixing drum, the grommet,
Rotating shaft, mixing arm and the mill ball are made by Hardmetal materials, and there is a horizontal arc groove grommet inner side, horizontal
To the radian of the radian more than mill ball of arc groove.
Preferably, the installation of every grommet and the mixing drum inwall is carefully bonded at seam by adhesive seal.
Preferably, the hard alloy agitating ball mill, also including lid, lid is used to seal ball mill mixing drum,
Air inlet and bleeding point are provided with lid, after cemented carbide powder is put into balling drum, by bleeding point to ball mill
Mixing drum is vacuumized, then the one kind in argon gas or nitrogen is input in ball mill mixing drum by air inlet, by control
Atmosphere in ball mill mixing drum processed, it is to avoid alloy powder is aoxidized, influences powder product quality.
Preferably, the hard alloy agitating ball mill, also including cooling water recirculation system, cooling water recirculation system bag
Include water pump, water leg, nozzle.Water pump and water leg, nozzle by conduit connect, arrangement of nozzles in stirring drum outer wall surrounding,
The water of water leg is extracted out by water pump, is sprayed in stirring drum outer wall, for cooling down ball mill mixing drum by nozzle.
Know-why of the invention is by setting horizontal arc groove on grommet, making material due to the effect of centrifugal force
It is gathered in groove, and mill ball is clashed into by mixing arm, collides the horizontal arc groove on mixing drum inwall grommet, is increased
Inwall grommet and the shock contact area of mill ball, when mill ball stress is laterally rolled in addition, improve mill ball and ball milling
The contact area of powder, so as to the efficiency of grinding, and ball milling effect is substantially improved.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, effective grinding part of the grinding method of this hard alloy powder is used and hard alloy powder identical material
It is made, has both improved the service life of equipment, improves operating efficiency, the thin powder and mixed cut that turn avoid that inner barrel wall weares and teares
Close powder different and influence the properties of mixed powder；
2nd, the special construction design of the drums inside in the ball mill that the grinding method of this hard alloy powder is used, by original
The mosaic mode arranged by polylith liner plate having has been changed into be inlayed by the grommet of unitary circular structure, and bonding strength increases, also not
Can be because one block of liner plate comes off so that entire row liner plate all comes off, the functional reliability of whole ball mill is greatly improved, interior
The replacement cycle of grommet greatly prolongs；
Grommet is designed integral circle by the hard alloy agitating ball mill that the 3rd, the grinding method of this hard alloy powder is used
Shape, and arc groove is set on the inside of ring mending, grinding efficiency is significantly improved, relative to ordinary rigid alloy agitating ball mill,
Shorten more than one times in the identical powder of grinding, and the time for producing a desired effect.
