Description
Technical field
The utility model relates to a kind of system that can produce fine mist of oil; This system can guarantee that mist of oil can overcome the influence of centrifugal force; Main shaft and cutter endoporus through rotation at a high speed arrives the processing district smoothly; Also can be used for the lubricated cooling of external cooling cutter, belong to the green cutting technology of the high-speed and high-efficiency field in the machining.
Background technology
Current, environment, resource, population become the three big subject matters that the world faces, the deterioration degree of global environment and day sharp increase, and the survival and development to human society cause serious threat.Manufacturing industry produces a large amount of discarded objects in will making the process that resource changes product into, form the primary pollution source of manufacturing industry to environment.Because manufacturing industry has a large capacity and a wide range, thereby very big to the general impacts of environment.We can say that manufacturing industry is the pillar industry of creation of mankind wealth on the one hand, but be again the main source of environmental pollution simultaneously.The restrictive policy of each item cutting fluid of releasing successively along with the raising and the various countries of human environmental consciousness; " green manufacture technology ", " environmentally sound technology ", " cleaner production ", " industrial ecology " etc. both can satisfy the production needs, rationally used the noun paid more and more attention of resource again.The greenization of manufacture process also becomes the focus that countries nowadays is competitively studied.
High-speed cutting is a kind of main technique technology of high-performance processing, has been widely used in aviation, mould, automobile and other industries.Because (8000～60000r/min) can produce centrifugal high speed, high pressure draught to the machine tool chief axis high speed rotary around cutter, rely on the conventional mode that strengthens the cutting fluid flow to be difficult to guarantee to have the cutting fluid of q.s to get into cutting region.Secondly, when the High-speed machining of general steel part, the blade of cutter will produce the high temperature near 900～1000 ℃; This moment is if supply with cutting fluid; The effect of cooling has been lost in the blade of moisture under the no show condition of high temperature instant vaporization before that cutting fluid is inner, also will cause the thermal shock to blade even arrive the cutting fluid of cutting blade once in a while; Blade is produced equal thermal phenomenon, therefore also can influence the service life of cutter.Such phenomenon adds at the raw-material low speed such as high temperature alloy that are easy to generate heat and also occurs often man-hour.Its theoretical reasons is that in process, cutter and Metal Contact surface produce high temperature; Under the cooling effect of traditional cutting fluid; High hot solids metal can quench cooled produce quenching effect, and the metal surface can produce the quenched martensite tissue, and fragility strengthens when making the metal hardening.Because quenching effect is directly proportional with the temperature difference, can make temperature higher and improve cutting speed, so will producing stronger quenching effect, raising speed cause cutter life to reduce.
How to adopt effective cooling and lubricating condition, can effectively reduce cutting temperature, improve the cutting Frotteurism, suppress tool wear, become the major technique approach of further raising working (machining) efficiency.Meanwhile, emerged the multiple eco-friendly novel green Machining Technology for Cutting that is used for substituting traditional wet cooling and lubricating processing method at the metal cutting manufacture field, the micro lubricating technology is wherein to represent.
The micro lubricating technology---MQL (Minimal Quantity Lubrication) is the nuisanceless mist of oil of in Compressed Gas, sneaking into trace, replaces a large amount of cutting fluids that cutting point is implemented cooling and lubricating.MQL is a kind of effective green manufacture technology, and cutting fluid is supplied with the high speed droplet, has increased the permeability of lubricant, has improved the cooling and lubricating effect, has improved the suface processing quality of workpiece; Use the amount of cutting fluid be merely ten thousand of traditional cutting fluid consumption/, thereby greatly reduce the cooling fluid cost, cutting zone outer cutter, workpiece and smear metal are kept dry, avoided a difficult problem that disposes waste liquid; MQL can stipulate lubricated optium concentration according to operating mode, and has eliminated the silicon particle pollution that suspends in the cutting fluid, has improved workman's working environment; The MQL system is simple, occupation of land is little, is easy to be installed on various types of lathes.
The MQL technological incorporation both advantages of DRY CUTTING and traditional wet cutting: on the one hand; MQL is reduced to the consumption of cutting fluid the degree of denier; Not only significantly reduce the use cost of cutting fluid; And, reduced the harm of cutting fluid to greatest extent to environment and human body through using the high synthesizing ester of natural degradation property as lubricant; On the other hand; Compare with DRY CUTTING, MQL makes the cooling and lubricating condition of working angles improve greatly owing to introduced the cooling and lubricating medium; Wearing and tearing between cutter, workpiece and the smear metal significantly reduce, and help to reduce the wearing and tearing of cutting force, cutting temperature and cutter.
The MQL liquid-supplying system mainly contains two kinds of forms: a kind of is the external liquid-supplying system; A kind of is built-in liquid-supplying system.The external liquid-supplying system is independent design; It is simple in structure that mist of oil is supplied with, and generally is made up of air compressor, oil pump, control valve, nozzle and pipeline fittings, and the system cost after integrated is cheap; Light weight need be transformed lathe hardly and just can be installed on the lathe easily.Lubricating oil and compressed air can be drawn by a plurality of nozzles after mix through mixing arrangement the lathe outside, act on the cutter and the workpiece of processing district.But the external feed liquid way exists following not enough: 1, because the orientation of nozzle to the lubricant effect influence significantly, needs to confirm the optimum position and the spray angle of nozzle.When the diameter of work of processing changes greatly or during tool changing, originally the position of nozzle must be passed through manual or pass through the correction of other aided positioning system, realize nozzle shaft to, radially with the correct location of angle.2, the droplet of external lubrication is difficult to get into the machining area of gun drilling, so bad for deep hole machining cooling and lubricating effect, also there is technologic difficulty in (like drilling) to specific processing method.Adopt technology at present, lubricant mist can only be realized the lubricated of draw ratio about 2～3 at most in the processing district.Also there is similar problem in the milling of deep hole member.Especially when processing dark narrow groove, frame, cavity configuration, outside lubricating system with trace amount nozzle interferes with cutter or workpiece easily, so droplet is difficult to the entering machining area, so for above-mentioned special processing, the cooling and lubricating effect of external lubrication is bad.3, the droplet particle of external lubrication is little, disperses everywhere easily, and working environment is had certain influence, so need supporting protective equipment.4, in addition, the time spent is done in external lubrication, fully and not causes waste for making to lubricate, and nozzle should be positioned as close to cutting region, and this moment, nozzle was destroyed by smear metal easily, and was prone to interfere, and is also influential to the tool changing process.More than these all become the obstacle of promoting outside micro lubricating technology.
Built-in liquid-supplying system is integrated in lathe inside, and lubricating oil and compressed-air actuated mixture import the processing district through machine tool chief axis endoporus and the built-in conveyance conduit of cutter, cool off and lubricate.Lubricant mist can directly arrive machining area, and is fully lubricated, and general effect can be better than external lubrication.But internal lubricating system also has shortcoming: make the structure of machine tool chief axis and tool system become complicated, even can influence the service behaviour of whole lathe; When the speed of mainshaft is too high, influenced by centrifugal action; Mist of oil is prone to stick to the inner hole wall of main shaft and instrument, is difficult for reaching cutting region, and therefore built-in supply system needs emphasis to consider the droplet generating apparatus; The diameter that generates droplet must be enough little; Just can avoid the influence of inertia and gravity, make droplet keep suspended state, thereby pass through the inner passage smoothly.
Built-in supply system promptly is a kind of fine mist of oil device, be with compressed air as power, make oil atomization, promptly produce a kind of as smog, the dry mist of oil of granularity below 2 μ m.Dry fog is compared with wet fog, is characterized in course of conveying, being difficult for sticking on the pipeline wall, can realize long distances, but mist of oil can not lubricate; Wet fog sticks in course of conveying on the tube wall antithesis easily, and fed distance should be controlled in the 5m, but the mist of oil lubricate.Because this specific character of dry fog, when using outlet, should manage to increase the flow velocity of air in long distances in the exit, make mist of oil become wet fog by dry fog, be lubricated then and cool off.
In addition; Along with the size dimension of interior cryoprobe tool different and in the size in cold hole also can corresponding difference; Will producing institute's required airflow mist of oil, what are also different, therefore how same built-in liquid-supplying system are carried out the air quantity mist of oil to different interior cryoprobe tools and regulate control and realize that best lubricated and cooling also is a difficult problem.

When A magnetic valve 3 started, source of the gas provided clean compressed air through air shooter 4, after compressed air filters once more through filtering pressure reducing valve 2 and transfers to required numerical value to pressure, flow to fine atomizer 9.Simultaneously, start miniature oil pump 7 and extract cutting oil 18 out from spray chamber 12 intracavity bottoms, and measure required oil mass, deliver to fine atomizer 9 then through quantity control valve 5 accent.Compressed air and cutting oil 18 mix at fine atomizer 9, and ejection forms fine mist of oil 11 at a high speed then, and fine mist of oil 11 comprises relatively large mist of oil particle of particle diameter and the less relatively mist of oil particle of particle.Wherein, Quality lighter small particle diameter elaioleucite 13 is relatively waftd to the inner chamber of spray chamber 12 and is flow in 30 inner chambers of primary sedimentation chamber through A mist of oil tube connector 22 at last, and big particle diameter elaioleucite 6 is sprayed onto on the bullet 10 of rotation at a high speed with part small particle diameter elaioleucite 13 1 superhigh speeds.After mist of oil was sprayed onto bullet 10, small particle diameter elaioleucite 13 rebound away, and was suspended in the inner chamber of spray chamber 12 and also flow in 30 inner chambers of primary sedimentation chamber through A mist of oil tube connector 22 at last.The big particle diameter elaioleucite 6 of part is clung formation fluid by bullet 10 surfaces and also down flow in the cutting oil 18 of spray chamber 12 intracavity bottoms owing to the gravity effect; The big particle diameter elaioleucite 6 of part is ground into small particle diameter elaioleucite 13 by the bump of bullet 10; The big particle diameter elaioleucite 6 of part is thrown away and is got rid of to spray chamber 12 inwalls by the bullet 10 of rotation at a high speed; The result is that part is cracked into small particle diameter elaioleucite 13 by bump, and remaining not being bonded on spray chamber 12 inwalls by the big particle diameter elaioleucite 6 of cracking also finally down flow in the cutting oil 18 of spray chamber 12 intracavity bottoms along inwall.Final result is; Lighter small particle diameter elaioleucite 13 is suspended in spray chamber 12 inner chambers and finally flowing in the primary sedimentation chamber 30 through A mist of oil tube connector 22, and the final because gravity effect of the heavier relatively big particle diameter elaioleucite of quality 6 is sunk to the cutting oil 18 of spray chamber 12 intracavity bottoms and can't get into primary sedimentation chamber 30.
The structure of bullet assembly and operation principle such as Fig. 3, Fig. 4 and shown in Figure 5; Bullet 10 belows are connected with support bar 16 through high-speed bearing; The base plate central point of the other end of support bar 16 and spray chamber 12 vertically is connected fixing; Support bar 16 plays the effect of cone of support body 10, must note guaranteeing that bullet 10 can only rotate and can not rock under compressed-air actuated blowing.Bullet 10 is provided with the circular step that continuous jump is arranged that encloses; And on the jump surface of bullet 10, be designed with four blades 49; Said blade 49 vertical taper, 10 inclined-planes and press branch such as circumference and install, the length on the length of blade 49 and bullet 10 inclined-planes is suitable.Be designed with gas nozzle 15 and be connected, and in air shooter 4 pipelines, be designed with proportional pressure-reducing valve 1 and A gas flow control valve 14 with air shooter 4.
The effect that the circular step of continuous jump is set on bullet 10 is, the vertical contact-making surface that increases mist of oil and bullet 10 is long-pending with the vertical impact surface that increases mist of oil, and reason is that vertically clash into stressed is maximum.Can guarantee that so more big particle diameter elaioleucite vertically bumps against bullet 10 surfaces at a high speed, and be ground into more small particle diameter elaioleucite by bump.After mist of oil is sprayed onto bullet 10; Blade 49 collisions that the big particle diameter elaioleucite of part is rotated are ground into the small particle diameter elaioleucite; The big particle diameter elaioleucite of part is bonded on the blade 49 and because of action of centrifugal force is compelled and is outwards thrown away by the bullet 10 of rotation at a high speed along blade 49 surfaces; And got rid of to spray chamber 12 inwalls; The result is that part is cracked into small particle diameter elaioleucite 13 by bump, and remaining not being bonded on spray chamber 12 inwalls by the big particle diameter elaioleucite 6 of cracking also finally down flow in the cutting oil 18 of spray chamber 12 intracavity bottoms along inwall.
When machine system was worked, compressed air further reduced pressure through proportional pressure-reducing valve 1 through behind the filtering pressure reducing valve 2 again; After being adjusted to aequum through A gas flow control valve 14 then; Flow to gas nozzle 15, on the blade 49 on after-blow to the bullet 10, blow bullet 10 rotation at a high speed.The effect of design proportion pressure-reducing valve 1 is, lets through the gas pressure of gas nozzle 15 lowlyer than the gas pressure through fine atomizer 9, can spray mist of oil smoothly to guarantee fine atomizer 9.The step-down ratio of proportional pressure-reducing valve 1 generally is made as 1:0.8～0.9, promptly reduces the gas pressure through proportional pressure-reducing valve 1 a little getting final product.The effect of design A gas flow control valve 14 is the control for the gas amount of carrying out that gas nozzle 15 is sprayed.The gas of gas nozzle 15 ejections has two effects, and one provides aerodynamic force guarantees bullet 10 rotation at a high speed; The 2nd, play make-up gas, to remedy the deficiency of fine atomizer 9 gases.During design, guarantee that the gas of gas nozzle 15 ejections can vertically blow to blade 49,, finally guarantee the high speed rotation of bullet 10 to guarantee blade 49 stressed maximums.
The spray chamber intracavity bottom is made as and stores cutting oil 18, and the maximum oil face must be lower than the bottom of A mist of oil tube connector 22.Being designed with liquid level sensor 17 all is connected with spray chamber 12 outer alarms 19 with 20, two liquid level sensors of following liquid level sensor.When adding cutting oil 18 in the past spray chamber 12, when the liquid level of cutting oil 18 in the spray chamber 12 reached the extreme higher position, last liquid level sensor 17 i.e. transmission information indication alarm 19 was reported to the police, and sends the caution that stops to refuel.When cutting oil 18 in the spray chamber 12 was consumed to its liquid level and drops to minimum liquid level, following liquid level sensor 20 i.e. transmission information indication alarm 19 was reported to the police, and sends the caution that needs to add cutting oil 18.
Link to each other through A mist of oil tube connector 22 between spray chamber 12 and the primary sedimentation chamber 30; The liquid level 10mm that connector position palpus assurance between spray chamber 12 and the A mist of oil tube connector 22 is higher than the cutting oil 18 of spray chamber 12 intracavity bottoms scurries in the A mist of oil tube connector 22 to prevent cutting oil 18.Be connected through B mist of oil tube connector 26 between primary sedimentation chamber 30 and the secondary precipitation chamber 32; B mist of oil tube connector 26 is in the middle of primary sedimentation chamber 30 inner chambers extend to primary sedimentation chamber 30 inner chambers, and the 90o angle of turning back then vertically extends to apart from top of chamber 5～10mm place in the primary sedimentation chamber 30.The small particle diameter elaioleucite 13 that suspends in the spray chamber 12 gets into primary sedimentation chamber 30 through A mist of oil tube connector 22, and in primary sedimentation chamber 30, carries out programmed screening and separate.In 30 inner chambers of primary sedimentation chamber, the average grain diameter of the mist of oil particle average grain diameter than the mist of oil grain in the spray chamber 12 is much little, and major part all is a small particle diameter elaioleucite 13, and it is relatively large having only the particle diameter of the mist of oil grain of few part.The big particle diameter elaioleucite 6 of part is owing to the gravity effect, and directly descending is sink to 30 bottoms, primary sedimentation chamber, and the big particle diameter elaioleucite 6 of part sticks on A mist of oil tube connector 22 and primary sedimentation chamber 30 inwalls and because the gravity effect down flow to primary sedimentation chamber 30 intracavity bottoms.The small particle diameter elaioleucite 13 that only is suspended in 30 inner chambers of primary sedimentation chamber can get into B mist of oil tube connector 26 through mist of oil inlet 29, and finally gets in the secondary precipitation chamber 32.The bottom of primary sedimentation chamber 30 is provided with A oil return opening 23, and A oil return opening 23 is communicated with the bottom of spray chamber 12 through A oil return pipe 24 and B magnetic valve 21.B magnetic valve 21 is a normally closed solenoid valve, and when machine system was worked, B magnetic valve 21 was in closed condition, in case mist of oil passes through from A oil return pipe 24, blows afloat the cutting oil of primary sedimentation chamber 30 intracavity bottoms; And after shutting down, B magnetic valve 21 is opened, and the cutting oil of primary sedimentation chamber 30 intracavity bottoms can flow back to spray chamber 12 intracavity bottoms through A oil return pipe 24.Design A mist of oil tube connector 22 keeps the distance about 10mm in the outlet of primary sedimentation chamber 30 inner chambers from primary sedimentation chamber 30 intracavity bottoms; To prevent machine system when work, the mist of oil that gets into primary sedimentation chamber 30 inner chambers blows the cutting oil that is deposited in intracavity bottom and splashes.
