Abstract

The invention relates to an intelligent control system for liquid nitrogen temperature, pressure and additive concentration suitable for low temperature cutting. Including online thermometer, online concentration meter, pressure limiting valve, electric valve, check valve, safety valve, pressure gauge, connectors, liquid nitrogen tank, mixing chamber, gas storage tank, host computer, air compressor, drying equipment and insulation pipeline. The upper computer adjusts the electric valve according to the parameters of pressure, temperature and additive concentration set by the user, and the pressure limiting valve controls the parameters at the main output to realize the intelligent regulation of liquid nitrogen pressure, temperature and additive concentration.

Description

technical field [0001] The invention belongs to the related field of low-temperature cutting and processing, and in particular relates to an intelligent control system for temperature, pressure and additive concentration suitable for liquid nitrogen low-temperature cutting. Background technique [0002] Difficult-to-machine materials such as nickel-based superalloys and titanium-aluminum alloys are widely used in aerospace. The high hardness and high strength of difficult-to-machine materials cause rapid wear of tools during the cutting process, making them one of the bottlenecks restricting the development of the aviation manufacturing industry. . During the cutting process, a large amount of cutting heat will be generated, which will cause rapid wear of the tool and serious thermal elasticity of the workpiece, and ultimately fail to obtain a satisfactory surface integrity of the workpiece. Traditional low-speed cutting uses cutting fluid and cold air, and the cooling effe...
