Embodiment Construction

[0011] Below, the present invention is described further in conjunction with embodiment: air compressor 1 communicates with nitrogen making drying device 2, after air enters nitrogen making drying device 2, moisture, oxygen etc. are separated through the adsorption of molecular sieve, and nitrogen is put out; Then, Through the nitrogen channel 4, the dry nitrogen is input into the refrigeration device 5 for cooling and cooling treatment, and water and oxygen are discharged from the other outlet 3; the low-temperature nitrogen is sprayed to the cutting area through the pipeline 4, forming a processing cooling system using low-temperature nitrogen . In order to ensure that the system can work continuously, the nitrogen drying device can be made into a double tower, that is: one tower works and the other regenerates, and the connection with the refrigeration device can be controlled by a unified control system. When working, as long as the air compressor and control system are tu...

Abstract

The invention relates to a low temperature nitrogen processing system which is mainly relative to the cooling of the cutting course. It cools the nitrogen abstracted by the atmosphere and then inputs it to the cutting point of the machine to replace the cutting liquid. It is characterized in that the nitrogen drier which is connected with the pressure air feed channel is connected with the cooling unit; the exit end of the cooling unit is connected with the entered end of the machine cutting used cooling media transmitting channel and springs to the cutting area to form low temperature nitrogen processing system.

Description

Technical field: [0001] The invention relates to a low-temperature nitrogen gas processing system, which is related to metal cutting processing technology, and is mainly aimed at cooling during metal cutting processing, so as to reduce the temperature rise of cutting points, prevent tool oxidation, reduce cutting agent consumption and prevent pollution. Background technique: [0002] In recent years, in order to reduce the pollution of cutting agents, in the field of metal cutting, the research on using air cooling such as compressed air, low-temperature compressed air, nitrogen, and liquefied nitrogen to replace cutting agents is very active. Among them, the most mature is the MQL technology, which is the technology of mixing a very small amount of pollution-free oil mist in the air to lubricate and cool the processing points. The latest is nothing more than the cold air cutting technology that lowers the air temperature to below -20°C on the basis of MQL technology. This ...
