Description

technical field [0001] The invention relates to the technical field of plastic forming of micron-scale shape structures, in particular to a radial high-frequency vibration type cavitation micro-plastic forming device. Background technique [0002] Microforming is one of the manufacturing methods based on the plastic forming process, which can produce parts with dimensions below the order of millimeters in at least two dimensions. With the miniaturization of equipment, the development of micro-electro-mechanical system structural components and precision machining, the demand for short, thin, light, small and other micro-shaped parts continues to increase. However, the difficulty of micro-forming processing is also gradually increasing. On the one hand, it comes from the continuous enhancement of the strength and performance of the processed workpiece, on the other hand, it comes from the continuous refinement and complexity of the structural design of micro-devices. The mic...

Problems solved by technology

However, in the current situation, there are many deficiencies in the traditional mechanical micro-shock technology and laser shock forming technology.

[0004] At present, the cavitation micro-forming technology is relatively novel and environmentally friendly, and has good development prospects, but the forming technology and forming theory are not yet mature, and the processing effect needs to be improved compared with other processing methods. The methods of forming effect include laser cavitation, ultrasonic cavitation, etc., but these methods generally can only induce single bubble collapse, and the cavitation jet intensity is low, which cannot meet the high forming accuracy requirements
