Anti-blocking cutting fluid filtering device of boring-milling machine

Abstract

The invention discloses an anti-blocking cutting fluid filtering device of a boring-milling machine. The device comprises an input liquid pump, a first filter tank, a second filter tank and an outputwater pump, the water outlet of the input liquid pump is connected with a water conveying pipe; the water conveying pipe is inserted into the first filter tank and extends to the bottom of the first filter tank; a drainage notch is formed in one side of the top end of the first filter tank; a drainage diversion trench is connected to the drainage notch; the tail end of the drainage diversion trench communicates with the second filter tank; a first baffle, a second baffle and a third baffle are sequentially arranged in the second filter tank; a first electromagnetic grid plate, a second electromagnetic grid plate and a third electromagnetic grid plate are correspondingly mounted at the tops of the first baffle, the second baffle and the third baffle respectively, a water outlet is formed inthe side, away from the drainage diversion trench, of the bottom of the second filter tank, and a water pumping pipe is connected between the water outlet and the output water pump.

Description

Technical field [0001] The invention relates to the technical field of filtering systems, in particular to an anti-clogging cutting fluid filtering device for a boring and milling machine. Background technique [0002] Cutting fluid is in the cutting process, both cutting and scoring and scratching occur between the grinding wheel and the material, which generates a large amount of cutting heat. The temperature of the cutting zone can reach about 400-1000℃. Under such high temperature, the material will If deformation and burns occur, the tool 2 will also be severely worn and the cutting quality will decrease. Under normal circumstances, cutting fluids are used in cutting processes to remove a large amount of cutting heat and reduce the temperature of the cutting zone. Effective use of cutting fluid can increase the cutting speed by 30%, lower the temperature to 100-150°C, reduce the cutting force by 10%-30%, and extend the tool life by 4 to 5 times. [0003] In order to save the...

Problems solved by technology

[0003] In order to save the cost of raw materials, it is generally necessary to recycle the cutting fluid during the cutting process. However, each cycle of the cutting fluid will take away some debris from the processing station, resulting in solids such as cutting dust in the recycled cutting fluid. Particle pollutants, and these solid particle pollutants are easy to damage the machined surface, resulting in a decrease in cutting quality. Therefore, solid-liquid separation and filtration are generally required in the process of cutting fluid recovery. However, debris in the current filter device is easy to accumulate, resulting in clogged, poor filtration
