Problems solved by technology

However, as the diameter of abrasive grains, jet pressure and jet beam diameter decrease, the conversion efficiency of jet kinetic energy to abrasive kinetic energy decreases rapidly, resulting in a great weakening of the processing capability of fine abrasive water jets. The impact of the jet stagnation zone formed on the surface on the movement of abrasive particles is becoming more and more obvious

Abstract

The invention relates to an ultrasonic vibration-assisted microchannel jet flow machining device which comprises a bracket platform. An abrasive material stirring box is placed on the bracket platform, an outlet of the abrasive material stirring box is connected to an abrasive material delivery pipe, and the end part of the abrasive material delivery pipe is connected to a nozzle. The ultrasonic vibration-assisted microchannel jet flow machining device is characterized in that a diaphragm type metering pump and an energy accumulator are arranged on the abrasive material delivery pipe, and a first ultrasonic vibration device is arranged in a position, close to the nozzle, of the abrasive material delivery pipe. The device capable of machining a high width-depth ratio microchannel efficiently by effectively reducing a pressure of a stagnation zone and controlling the moving state of an abrasive material in a machining process is provided.

Description

technical field [0001] The invention belongs to the technical field of abrasive water jet processing, and in particular relates to a device capable of controlling microchannel jet processing by using ultrasonic vibration. Background technique [0002] Microfluidic technology characterized by a microchannel network is an emerging technology that uses microfluidic chips to control and utilize fluids, and realizes the combination with microelectronics, optics, energy, biomedicine and other fields at the micron scale. Microfluidics At present, the control chip has achieved commercial production, but its technical level is far behind the speed of semiconductor development predicted by "Moore's Law". Among them, the main bottleneck hindering the development of microfluidic technology is the problem of manufacturing, processing and application. Commonly used microfluidic chips are mainly made of hard and brittle materials such as silicon, quartz, glass, and ceramics. They have the ...
