Description
Technical field
The present invention relates to a kind of spheroid mill with V-type groove is situated between and manufacturing approach.
Background technology
Powder processing at present is processing method commonly used in modern industry and the new high-tech industry; The annual material that needs to pulverize grinding through ball mill of China has billions of tons; Along with production-scale expansions such as chemical industry, metallurgy, machine-building, cement, potteries; The power consumption of comminuting matter has reached 10%～20% of the total power consumption in the whole world, pulverizes the Grinding Quality increasing demand because of material and promotes, and power consumption increases progressively at double.There are some researches show that about 50% grinding modes owing to existing energy consumption equipment and poor efficiency of world energy sources total amount are fallen by unnecessary consumption.Consider that ball mill is used for large-scale powder processing and the energy of labor, the energy-conservation effect problem of carrying of ball mill is given prominence to.
When proposing different powder processing request, effectively improve the efficient of large-tonnage process equipment and extraordinarily paid close attention to granularity, shape, the surface characteristic of material.Although over past ten years, quite rapid to the development of ultra-fine grinding and classification technique, a lot of effort of being done all are difficult to replace ball mill.
The ratio of reduction is big, operating rate is high, adaptability is strong, be easy to advantages such as manipulation having aspect the general milling machine material handling; But also exist shortcomings such as capacity usage ratio is low, the product grind size is inhomogeneous simultaneously; As be applied to crushing strength 200MPa endoparticle grinding and pulverize; Pulverize section formation and have contingency, not alternative, the chip-proof while exists the local pulverizing of crossing again in the part, influences the crush efficiency of ball mill.
For ball mill, it is situated between through mill in the rotating cylinder enhancing tube, and mill is situated between rushes down with projectile motion and realize impact and grinding to powder granule, and process is divided into four parts: lifting, slippage, leave and quicken.Quicken with lifting process in, leave the medium that gets off and can lose original linear velocity and angular speed, with the cylindrical shell motion, relative motion is less between mill ball, particle and the barrel at this moment under the frictional force effect, abrasive action also a little less than.In the slippage stage, mill is situated between and is thus lifted to certain altitude, and the gravity overcome friction begins to occur the aspect slippage, helps powder is ground.In the process of leaving; Mill is situated between material is formed strong impact effect; The zone of its pulverization of powder mainly occurred in leave the zone and rush down the territory of settling in an area; It is thus clear that, the ball mill grinding ball most of zone and time not to its pulverization of material, so this has been modified into an important research project.
Summary of the invention
For the low problem of crush efficiency that overcomes the ball mill that exists in the prior art, the present invention provides a kind of contact area that increases mill Jie and material, and the spheroid mill with V-type groove that improves the working (machining) efficiency of ball mill is situated between and manufacturing approach.
The technical scheme that the present invention adopts is:
Spheroid mill with V-type groove is situated between, and comprises mill Jie body, and it is characterized in that: said mill Jie body is provided with a plurality of grooved rings that are interspersed that increase said mill Jie body and material contact area.
Further, said grooved ring and said mill Jie body are the donuts of the same centre of sphere.
Further, said grooved ring is that with said mill Jie body first, second is diameter.
Further, said first with second perpendicular.
Further, said grooved ring comprises the V-type groove of a plurality of equidistant distributions.
Further, be that the grooved ring of diameter comprises 12 V-type grooves with said first, be that the grooved ring of diameter comprises 3 V-type grooves with said second.
The manufacturing approach that spheroid mill with V-type groove as described above is situated between, it is characterized in that: said method is a grinding method.
Further, the step of said grinding method is:
(1) mill Jie positioning and clamping of processing is to mill Jie special fixture, and is fixed on the abrasive working appts;
(2) process according to the degree of depth of V-type groove.
Further, described abrasive working appts comprises the magnet and the milling cutter of grinding machine spindle, belt coil, and said magnet is installed on the said grinding machine spindle, and said milling cutter is installed on the said magnet.
The present invention selects the suitably special-purpose milling cutter of size, the physical dimension of grinding the groove that is situated between according to the V-type groove according to tool categories all on the market in manufacture process; The distance that is the highs and lows of groove is carried out the control of processing capacity, because an attrition process amount is less, so flowing current separation of processing is selected 8 ~ 10 times in process; Because the size that mill is situated between is less, the mismachining tolerance of any point all has bigger influence to the precision that mill after processing is situated between, so in process, will reduce mismachining tolerance; Work in-process; Strict requirement is made in the compensation of cutter, promptly on the processing amount of feeding, added the half the of special-purpose milling cutter diameter, when being worked into V-type bottom land end; Reduce the speed of tool feeding; Simultaneously, in process, also need come the intensity of controlling magnetic field to the control of electric current, very big influence will be caused to precision in stable electric current and magnetic field.
The present invention selects an amount of machining gap in process, can obtain less roughness; In the process of processing; The rotating speed of controlling milling cutter to be to improve the removal amount and to reduce surface roughness, also need man-hour the abrasive particle size be controlled adding simultaneously, because the too for a short time grinding effect that do not reach of abrasive particle; The excessive cut to abradant surface of abrasive particle increases, thereby the grinding of powder is impacted.In the process of making processing; Need be provided with in numerical control programming and technology the above is made requirement to guarantee the quality of processing; In the process of digital control processing; Take all factors into consideration the factor of each side, promptly according to the physical dimension of mill Jie V-type groove and machining accuracy two aspects to the process of the processing processing of programming.
Because it is spherical grinding Jie, cutter adopts the feeding processing of vertical direction in process, and mill Jie can have 360 ° of directions under the clamping of special fixture rotation is to reach the shape that processes.
Beneficial effect of the present invention is embodied in:
1. the self-sharpening of abrasive particle can be good, and grinding capacity is strong, and working (machining) efficiency is high;
2. temperature rise is little, and workpiece deformation is little, and cutting depth is little, and finished surface is smooth bright and clean, and machining accuracy is high;
3. flexibility (adaptability) of operation is strong, can process a lot of complex surfaces;
4. the mill that processes of the present invention is situated between owing to there is groove, can strengthen mill and be situated between to the working application time of material increasing material and the contact area that mill is situated between, thereby improve the efficient and the productivity ratio of ball mill.
