一、概述气动式喷丸设备比较灵活,可以喷形状比较复杂的零件,故多用于喷丸强化。气动式喷丸设备的一个重要组成部分是喷嘴。目前国内外对喷嘴的研究都很重视,从结构形式到材料,都作了大量的研究工作,根据报导主要有以下几个方面: 1.结构形式喷嘴的几何形状对弹流速度影响很大,在相同的空气压力条件下,喷嘴结构合理可以获得较高的弹流速度。一般说来,喷嘴的形式有 First, an overview Pneumatic shot peening equipment more flexible, spray shape can be more complex parts, it is often used for shot peening. Pneumatic blasting equipment is an important part of the nozzle. At present, the research on nozzles at home and abroad attaches great importance to a large number of research work, from the structure to the material, according to the report mainly in the following aspects: 1. The structure of the nozzle geometry has a great impact on the spring velocity, Under the same air pressure conditions, the nozzle structure is reasonable to get a higher velocity of the spring. In general, the nozzle form there
