Low temperature water mist and oil mist cutting cooling lubrication supply system

Abstract

The invention discloses a low temperature water mist and oil mist cutting cooling lubrication supply system. A Venturi atomization sprayer is arranged at the upper portion of an inner cavity of an atomization chamber, an air inlet of the Venturi atomization sprayer is connected to the outlet end of an air tank through a first air conveying pipe, an eddy atomization sprayer comprises an eddy pipe and an oil-water mixing sprayer, the eddy pipe is connected to the outlet end of the air tank through a second air conveying pipe, and a compression refrigerator is arranged on the second air conveying pipe; the oil-water mixing sprayer is connected with the water tank through a water pipe, and is connected with the atomization chamber through an oil mist conveying pipe; and cold air refrigerated through the compression refrigerator and the eddy pipe is mixed with oil mist coming from the atomization chamber and water coming from the water tank at the position of the oil-water mixing sprayer. By means of the system, advantages of low-temperature cold air and composite spraying mist are combined, and therefore when a cutter is used for machining difficultly-machined materials such as the titanium alloy, the high-temperature alloy and the aviation composite material, the cutting temperature is rapidly decreased, the machining process is more efficient, and the service life of the cutter is prolonged.

Description

technical field [0001] The invention relates to the technical field of high-speed and high-efficiency green cutting in mechanical processing, in particular to a cooling lubrication supply system for low-temperature water mist and oil mist cutting. Background technique [0002] High-speed cutting is a high-performance process technology that has been widely used in aviation, mold, automobile and other industries. The extensive use of cutting fluid in traditional cutting has become an important pollution to the environment in the machining industry, and has caused various negative effects. Discarded cutting fluid will pollute the soil and air, and the cutting fluid is harmful to the human body. It will cause various diseases after being inhaled into the human body, and the cost of using the cutting fluid is also high, and it will corrode the machine tool during use. sex. The ability of the cutting fluid to penetrate into the processing area is the key to measure the lubricat...

Problems solved by technology

[0003] Traditional minimal quantity lubrication technology, due to the high temperature in the cutting area, a small amount of cutting oil will easily lose the lubricating effect at high temperature, and cannot achieve a good cooling effect, which seriously affects the life of the tool and the quality of processing

Traditional oil mist and water mist composite spray technology, although the fine water droplets can absorb a lot of heat during the atomization process, compared with the heat generated during the processing, the processing effect of the composite spray technology is still not significant, especially in the processing of titanium For difficult-to-machine materials such as alloys, high-temperature alloys, and aerospace composite materials, the cutting temperature will be higher, and the cutting temperature will have a more significant impact on the life of the tool
