For the central lubricating system of the machining micro lubricating type of cooling
Technical field
The utility model relates to machining technical field of auxiliary equipment, particularly relates to the central lubricating system for the machining micro lubricating type of cooling.
Background technology
In mechanical processing process, cutting tool and processing metal contact surface can produce high temperature, lower the temperature for making it, cooling oil can be sprayed at processing metal contact surface and cutter place, but under the effect of general cooling oil, high hot solids metal can cool generation quenching effect rapidly, and metal surface can produce quenched martensite tissue, and while making metal hardening, fragility strengthens.
Because quenching effect is directly proportional to the temperature difference, and improve cutting speed temperature can be made higher, therefore the stronger quenching effect of generation causes cutter life to reduce by raising speed, how to adopt effective cooling and lubricating condition, effectively can reduce cutting temperature, improve and cut Frotteurism, suppress tool wear, become the Major Technology improving working (machining) efficiency further, lubricating system with trace amount arises.
Lubricating system with trace amount is exactly briefly the fueling injection equipment of precise hard_drawn tuhes oil mass, is usually divided into outer oil spout and interior fueling injection equipment.
Outer fueling injection equipment is that cutting fluid and compressed air independently regulate, and cutting fluid is blowed to cutting blade by high velocity air at nozzle exit by compressed air, realizes lubrication; The cutting fluid of lubricating system with trace amount ejection mainly plays two effects in metal cutting, and one is lubrication; Two is cooling effects.
In order to improve production output, great majority are that factory realizes personnel two classes, class Three changes, machine 24 hours continual mode of operations, after cutting fluid in lubricating system with trace amount uses, need manually to supplement, supplement cutting fluid operation comparatively loaded down with trivial details, the supplementing of cutting fluid of a machine tool probably needs general 10 ~ 15 minutes of cost, and production line at least also has several to tens lathe as many as several thousand lathes in work, so how to shorten, to cut fluid time of supplementing be the difficult problem that factory needs to solve; And supplement the container of fluid and cannot ensure that it is totally spent, namely impurity may enter in lubricating system with trace amount along with fluid, and service time is more of a specified duration, accumulates more, the service life of the precise parts such as the pump of lubricating system with trace amount and valve finally can be had a strong impact on; In addition, due in the running water of most area containing the fine impurity such as iron rust, as without filtration treatment, impurity can be deposited on liquid-supplying system inside, long-time use after, also can affect the service life of the precise parts such as the pump of lubricating system with trace amount and valve; And, generally the chlorinated products such as clorox are used in a large number in the production process of running water, the chlorion of meeting corroding metal then can be remained in water, as can not be effectively removed, metal parts then in water system then has the risk be corroded, and the water smoke of ejection also has the possibility of corroding metal, in order to ensure the anti-corrosive properties of water, then need the Corrosion Protection improving water-soluble metalworking liquid, use cost is corresponding improve also.
Finally, the running water hardness in the more place such as northwest and North China is higher, and after Long-Time Service, liquid-supplying system inside also has incrustation scale, also can affect the service life of the precise part such as pump and valve of lubricating system with trace amount.
