Abstract

The invention relates to a device and a method for stamping and etching a micro part based on high-pressure submerging and cavitating water jet. The method is characterized in that high-pressure impact wave, high-speed micro jet and local high temperature generated by cavitation collapse in high-pressure submerging and cavitating water jet are utilized, and a corresponding mould is combined to stamp or etch and process the micro part, so that a needed shape is formed by stamping or accumulative etching. A device used for generating high-pressure submerging and cavitating water jet comprises awater storage tank system, a metering pump-energy accumulator-unloading valve constant-pressure energy system, a cavitating water jet generating system, a high-pressure submerging and processing system, a circulating loop system and related peripheral equipment. Different from a conventional processing method, the method disclosed by the invention enriches the processing method for stamping and etching the micro part, so that stamping degree and precision, and etching and processing precision and efficiency are improved greatly; and the whole device is simple in structure, is easy to operate,is easy to maintain, is relatively low in cost, and is environmentally friendly.

Description

technical field [0001] The invention relates to the fields of mechanical manufacturing, material forming and special processing, in particular to a device and method for stamping and etching micro-parts based on high-pressure submerged cavitation water jets. Background technique [0002] In the industrial field, there are more and more applications for various micro components, especially in the fields of biology, environmental monitoring, aerospace, industry and defense. Due to changes in scale effects, structures, materials, and working principles, the forming and processing of micro-parts is becoming more and more difficult, including the difficulty of forming and processing brought about by the improvement of material properties, and the complexity brought about by the tiny structure of parts. For example, the strength of steel increases from 250MPa to 1000MPa, the plasticity decreases from 45% to 12%, the strength of aluminum alloy increases from 150MPa to 530MPa, and t...
