Description

technical field [0001] The invention relates to the field of ultrasonic vibration focused vapor-mist cooling utilizing the inverse piezoelectric effect, in particular to a split-type ultrasonic focused vapor-mist cooling device. Background technique [0002] In the process of material grinding, there is an attached airflow layer on the surface of the high-speed rotating grinding wheel that rotates with the grinding wheel. The airflow layer forms an air barrier in the grinding processing area, making it difficult for the coolant to enter the grinding processing area, resulting in the cooling of the coolant. No cooling effect. During the material grinding process, due to the cutting, sliding and friction of the cutting edge of the tool on the surface of the workpiece, a large amount of cutting heat will be generated in the grinding processing area, so that the grinding processing area is in a high temperature state. When the temperature reaches a certain critical After the va...

Problems solved by technology

[0004] 1. The cooling effect is poor, which affects the quality of the machined surface and machining accuracy, and affects the cutting efficiency and tool life;

[0005] 2. During the material cutting process, the high-speed rotation of the tool will cause the coolant to splash, and the oil or chemical additives contained in it will cause environmental pollution and damage the health of the operator;

[0006] 3. The cost of coolant recycling is high, and waste coolant will also cause environmental pollution

[0008] In order to overcome the deficiencies of the above cooling technologies, the patent document with the publication number CN101966661A discloses an ultrasonic focused vapor-mist cooler, which adopts a sandwich transducer structure, has a large power capacity, The advantages of strong fog focusing ability, and on the basis of high-efficiency cooling, can reduce the amount of coolant, but the ultrasonic focused vapor-mist cooler also has some defects. This ultrasonic focused vapor-mist cooler needs to ensure The natural frequency of the piezoelectric transducer part is the same as the natural frequency of the focusing spherical shell part, and the focusing spherical shell part must be installed at the antinode position of the longitudinal vibration of the vibrator structure, which is difficult to manufacture and adjust; the atomization part and the focusing ball The shell part shares a piezoelectric transducer, so that the power distributed to the front part of the atomizer and the focusing spherical shell part is small, resulting in poor atomization effect and focusing effect; and it is inconvenient to disassemble and maintain; if the ultrasonic focused vapor-mist cooling If any part in the device is damaged, the entire system may not work, and the entire system needs to be replaced and repaired, and the later maintenance costs are relatively high.
