Problems solved by technology

The technical problem existing in the current cryogenic cutting technology is that it is impossible to realize the effective monitoring of the flow rate of liquid nitrogen. If the flow rate of liquid nitrogen is too low, it is difficult to achieve an effective cooling effect. If the flow rate of liquid nitrogen is too large, it cannot achieve a better cooling effect. Waste of liquid nitrogen

Abstract

The invention relates to a liquid nitrogen flow intelligent regulating, controlling and cooling system suitable for low-temperature cutting. The liquid nitrogen flow intelligent regulating, controlling and cooling system suitable for low-temperature cutting comprises an infrared thermometer, two rotating nozzles, low-temperature flowmeters, low-temperature electric valves, conveying pipelines, a liquid nitrogen tank, a central processing unit and pipe fittings for connecting. According to the system, the infrared thermometer is used for detecting the temperature of the front cutter surface andthe rear cutter surface on line and feeding back the temperature to the central processing unit, the central processing unit is used for controlling the liquid nitrogen flow of each pipeline throughthe low-temperature flowmeters and the low-temperature electric valves on the upper pipeline, the lower pipeline and the main pipeline according to the set temperature, and finally the intelligent regulation and control of the liquid nitrogen flow are realized.

Description

technical field [0001] The invention belongs to the related field of metal cutting, and in particular relates to an intelligent control and cooling system for liquid nitrogen flow suitable for low-temperature cutting. Background technique [0002] Difficult-to-machine applications such as titanium alloys and high-temperature alloys are widely used in aerospace and other fields, but the cutting temperature is high during the cutting process, the tool wear is severe under the high-temperature environment, and the quality of the workpiece surface is difficult to control. The cooling effect of traditional cutting fluid is not ideal, and cutting fluid will cause environmental pollution. Therefore, cryogenic cutting technology came into being. Spraying liquid nitrogen into the cutting area can effectively remove the heat generated during cutting, improve the processing quality, and be more environmentally friendly. The technical problem existing in the current cryogenic cutting t...
