Embodiment Construction

[0024] The present invention will be described in further detail below with reference to the drawings.

[0025] Such as figure 1 As shown, the present invention includes a housing 1 and a nozzle 2. The housing 1 is sleeved on the nozzle 2, and the gap between the housing 1 and the nozzle 2 forms an outer flow channel 102 for low-pressure liquid to flow. The housing 1 is provided with a low-pressure liquid interface 101, and the nozzle 2 is provided with an inner channel 201 for high-pressure liquid to flow. Such as figure 1 As shown, when the device is working, the high-pressure liquid flows along the inner channel 201 and is ejected to the surface 4 of the workpiece, and the low-pressure liquid flows along the annular outer flow channel 102 formed between the housing 1 and the nozzle 2 and is ejected to The surface of the workpiece 4, and the low-pressure liquid and the high-pressure liquid are ejected coaxially. The high-pressure liquid comes into contact with the low-pressure ...

Abstract

The invention relates to the field of shock processing, in particular to a shock processing device based on a bubble-sweepdown effect. The device comprises a housing and a nozzle, wherein the housingis arranged on the nozzle in a sleeving manner, an outer runner where a low pressure liquid flows is arranged between the housing and the nozzle, a low pressure liquid connector is arranged on the housing, an inner pore canal where a high pressure liquid flows is arranged in the nozzle, the low pressure liquid and the high pressure liquid are coaxially sprayed to the surface of a workpiece, and air dissolved in the high pressure liquid is separated out to form microbubbles which are broken on the surface of the workpiece. By configuring a relationship between the pressure and the sprayed position of the high and low pressure liquids reasonably, microbubbles are generated in the high pressure liquid, so that strengthening action to the surface of the workpiece is achieved by means of shockwaves formed by breakage of the microbubbles, and therefore, the cost of the shock processing device is lowered effectively and the demand on a surrounding environment is reduced effectively, and theapplication range of the shock processing device is expanded greatly.

Description

Technical field [0001] The invention relates to the field of impact strengthening processing, in particular to an impact strengthening device based on the cavitation impact effect. Background technique [0002] Impact strengthening technology has been widely used in the surface performance strengthening treatment of a variety of complex structural parts of metal materials. Impact strengthening technology can be divided into laser impact strengthening, shot peening, etc. according to the different strengthening methods. However, the existing impact strengthening methods have disadvantages such as high equipment cost and many harsh requirements on the use environment, which limits the impact strengthening technology. The scope of applications for strengthening the surface of complex structures. [0003] There are many methods for surface impact strengthening of materials. For example, the invention patent with publication number CN109136529A discloses a method for material impact st...
