Amount lubrication Intelligent sprayer system.
Background technique
Tradition machining carries out cooling and lubricating, this cooling to processing district using a large amount of emulsions, cutting oil, coolant etc.
Lubricating system utilization rate is low, increases huge processing cost, and if the coolant liquid scrapped deal with improperly will be to environment
It causes greatly to injure.Dry-type processing technology is a kind of environmentally protective processing technology occurred earliest, it originates from auto industry.
It has been successfully applied in the machining such as turning, turning, drilling and boring.It does not instead of simply abandon cutting fluid completely,
Under the premise of guaranteeing part processing precision and cutter life, the use of cutting fluid is abolished.However dry-type processing is not
The problems such as solving the problems, such as that cutting region is cooling, causing burned work-surface, surface integrity deterioration.
Emulsion flooding is poured in Minimal Quantity Lubrication Technology replacement, dry-type processing technology has become inexorable trend, has adapted to green system
Make the theory with sustainable development.It refer to by micro lubricating fluid, water and with certain pressure gas mixing atomization after, spray
It is mapped to a kind of technology that cooling and lubricating is played the role of in cutting region.Water and high pressure gas play cooling effect, and oil plays lubrication cutting
Area, the effect for extending cutter life.At present the research of Minimal Quantity Lubrication Technology is had been achieved for centainly being in progress, micro lubricating is set
Standby design research and development become the important content that Minimal Quantity Lubrication Technology is realized.Although many designers devise lubricating system with trace amount,
However various problem is still remained in practical applications.
The prior art has made intensive studies micro lubricating equipment, devises nanoparticle jet stream micro lubricating grinding three
Mutually stream feed system, its main feature is that: nano-fluid is delivered at nozzle through fluid path, while high pressure gas enters spray through gas circuit
Mouth, high pressure gas and nano-fluid are sufficiently mixed atomization in nozzle mixing chamber, and accelerated room enters minor air cell after accelerating, simultaneously
Compressed gas enters through minor air cell's venthole, so that three-phase flow is further rotated mixing and accelerates, then three-phase flow is with atomized drop
Form spray through jet expansion to grinding area.
The lubricating system with trace amount precision lubricating pump of prior art design, its main feature is that: lubricant enters from the fuel feed hole
In the fluid chamber；By compressed air-driven, when compressed air enters the air chamber, the pressure of the piston rod tail portion increases
Greatly, when pressure is greater than the elastic force of the piston spring of the piston rod front end, the piston rod is moved forward, the liquid
Chamber reduces, and pressure increases, and when pressure is greater than the elastic force of the one-way valve spring, the check valve plug is opened, lubricant pump
Out；The liquid chamber pressure release, when pressure is less than the one-way valve spring, the one-way valve spring resets, oil outlet
It is closed；When the gas cavity pressure discharges, piston rod tail portion pressure is less than the elastic force of the piston spring, the piston rod
It resets.It the advantage is that and the Miniature precision air driven pump of the accurate fuel feeding of energy is provided, design is accurate, is used in suitable for a variety of lubricants
In the lubricating arrangement of intermetallic composite coating.
The continuous liquid supply type micro lubricating arrangement of prior art design, its main feature is that: device includes peristaltic pump, gas source processing
Device, gas source tracheae, gas inlet tube, infusion tube, goes out liquid hose, gas-liquid coaxitron, nozzle and for installing at gas-liquid connector
The cabinet of component is stated, the air-source treater is fixedly mounted on the outside of the cabinet, and the import of the peristaltic pump passes through
The infusion tube connect with the container for holding cutting fluid, and outlet is by going out the of liquid hose and the gas-liquid connector
One import connection；The import of the air-source treater is connect with gas source tracheae, and outlet passes through gas inlet tube and the gas-liquid
Second import of connector connects；The outlet of the gas-liquid connector is connect by the gas-liquid coaxitron with the nozzle,
Compressed air and cutting fluid mix in the nozzle, form cutting fluid aerosol and spray.With compact-sized, operation letter
Just, fuel-flow control is accurate, continuously supplies the features such as cutting fluid, install convenient.
Although three of the above minimum quantity lubrication device is instead of traditional cast-type, they are connected in a manner of micro lubricating
Nozzle structure is still traditional everything pipe, and people are by processing horizontal lathe before carrying out horizontal lathe processing processing
Understand, spray head is approximatively directed at lathe tool, but when horizontal lathe processing, will lead to the work that cutting fluid can not be ejected into lathe tool
Around point, waste and the burned work-surface of cutting fluid are caused, also has no idea to realize that cutting fluid processes progress to horizontal lathe
Injection is continuously tracked.
