Description
Technical Field

Background
The water jet technology is a novel material processing technology, and is widely applied to various fields of mining, military activities, mechanical manufacturing and the like due to the characteristics of small mechanical vibration, no dust, low cutting heat and the like in the processing process. In the aspect of surface shot peening, the water jet technology has the advantage of being unique. The solid shot adopted by the traditional shot blasting technology is easy to form larger surface roughness on the surface of the part, and once the shot is broken and embedded into the surface of the part, the surface performance is further deteriorated. The water jet is used as a flexible processing means, the surface roughness caused in the impact process is low, the effects of fine grain strengthening and tissue strengthening can be achieved, the surface can be subjected to fine polishing by means of radial jet flow generated after impact, and the comprehensive performance of the surface of the part is comprehensively improved.
The water jet applied to the surface strengthening treatment can be mainly divided into three types, namely cavitation jet, abrasive jet and pulse jet. The existing water jet peening device mainly uses cavitation jet and abrasive jet, has a single structure, mostly adopts a single nozzle, is only suitable for surface single-point strengthening of small parts, and has defects. As the cavitation jet peening apparatus disclosed in application No. 201910316307.5, since the cavitation intensity is not easily controlled, it is difficult to control the peening quality; the abrasive jet blasting apparatus disclosed in application No. 201811097395.6 is capable of easily embedding abrasive particles into the surface of a material during blasting, thereby adversely affecting the surface of a part. In recent years, with the rise of pulse jet research, pulse jet peening has also become a hot spot in the water jet field. However, the research on the pulse jet at present in China is still limited to the traditional mining industry, and the application of the pulse jet to the surface strengthening of parts is still in the starting stage. The periodic discrete impact caused by the pulse jet is considered to be a special shot blasting mode closest to the shot blasting process. Due to the existence of the water hammer effect, the pulse jet can generate larger periodic instantaneous impact force at lower impact speed, the requirement on the rated pressure of the high-pressure pump is low, the shot blasting parameters can be controlled easily when the pulse jet is generated by a mechanical modulation mode, and no solid particle medium is added, so that the method is the most ideal water jet shot blasting mode at present.
The invention discloses a high-efficiency multi-cluster pulse water jet peening device which adopts an integrated multi-hole nozzle to generate distributed multi-cluster jet flow, and utilizes an internal servo regulation and control mechanism to periodically modulate the water jet flow, and adopts a three-axis gantry type structure to control a peening area. Compared with the existing water jet peening device, the device has the advantages of high peening coverage rate, controllable peening intensity, low pressure pump rated pressure requirement and the like, and can perform efficient surface strengthening treatment on large-size plates.
