The double-nozzle type liquid nitrogen cooling system of the present invention comprises a liquid nitrogen ** source, a flow unit, a liquid nitrogen delivery pipe and a liquid nitrogen nozzle unit. The liquid nitrogen ** source will output the low-temperature liquid nitrogen in a controlled manner, and the flow unit will continue to transport the liquid nitrogen to the liquid nitrogen delivery pipe, and monitor the flow rate of the liquid nitrogen flowing through it. The liquid nitrogen transfer pipe continues to transport the liquid nitrogen to the liquid nitrogen nozzle unit in a dual-nozzle structure, which allows the liquid nitrogen to be injected separately and flank of the tool separately and controllably, without being vaporized. Through this design, the good application of low-temperature liquid nitrogen in the cutting process of Inconel718 alloy can be realized, and the good application of low-temperature liquid nitrogen in the cutting process of Inconel718 alloy can be realized accordingly.
Compared with the traditional cutting fluid, the double-nozzle type liquid nitrogen cooling system of the present invention has the following advantages: firstly, the liquid nitrogen has an extremely low temperature, which can quickly absorb the cutting heat, reduce the surface temperature of the tool and the workpiece, and improve the machining accuracy and surface quality;Secondly, liquid nitrogen has a high density, which can form a protective layer in the cutting area to prevent the oxidation of the tool by oxygen in the airThirdly, liquid nitrogen can be vaporized into gas and discharged out of the processing area, taking away iron filings and dirt in the cutting area, and keeping the processing environment cleanFinally, liquid nitrogen is chemically stable and does not corrode tools and workpieces, nor does it cause harm to the environment and human body.
The present invention can not only realize the good application of low-temperature liquid nitrogen in the cutting process of Inconel718 alloy, but also can obtain more accurate directional control from many aspects such as liquid nitrogen dosage, liquid nitrogen injection position and liquid nitrogen storage tightness. Through the monitoring of the liquid nitrogen flow rate by the flow unit, the precise control of the amount of liquid nitrogen can be realized, avoiding unnecessary waste and environmental pollution. The design of the dual-nozzle liquid nitrogen cooling system allows liquid nitrogen to be accurately sprayed on the rake and flank faces of the tool, allowing for better control of the cutting process and quality. In addition, the system also has the advantages of clean environmental protection, cutting *** and easy control, bringing a new development direction for the field of metal cutting processing.
To sum up, the double-nozzle liquid nitrogen cooling system of the present invention is suitable for inconel718 cutting, and has the advantages of high efficiency, environmental protection, safety and reliability. Through the application of this system, the processing efficiency and processing quality of Inconel 718 alloy can be significantly improved, the production cost and energy consumption can be reduced, and at the same time, it has made a positive contribution to environmental protection. The present invention is of great significance for promoting technological progress and development in the field of metal cutting processing.
