中文摘要钢丸加工技术是提高零件疲劳强度的一种重要方法。这种方法近几年在各个工业部分中得到了迅速的推广和使用，并已经标准化。喷丸加工技术不仅能显著提高零件的疲劳强度，而且还能提高零件的耐应力腐蚀能力。喷丸加工工艺还有其成本低，生产效率高等优点。这也是活的广泛应用的主要原因之一。将对喷丸器的基本原理及分类，最新型喷丸技术，以及在实际应用等进行阐述和分析。用喷丸进行表面处理，打击力大，清理效果明显。但喷丸对薄板工件的处理，容易使工件变形，且钢丸打击到工件表面（无论抛丸或喷丸）使金属基材产生变形，由于Fe3O4和Fe2O3没有塑性，破碎后剥离，而油膜与基材一同变形，所以对带有油污的工件，抛丸、喷丸无法彻底清除油污。在现有的工件表面处理方法中，清理效果最佳的还数喷砂清理。喷砂适用于工件表面要求较高的清理。本文通过PRO\E三维建模和理论计算的方法,设计了一套属表面纳米化高能喷射器，其设计内容包括结构布局和电机的选择，最终进行集成块零件图和系统装配图的绘制。60336

Title    Shot peening technology                     

Abstract Shot peening technology is an important method to improve the fatigue strength of parts. This method in the past few years in various industrial parts has been promoted and rapid, and has standardized. Shot peening technology can not only significantly improve the fatigue strength of parts, but also improve the part stress corrosion resistance. Shot peening process has the advantages of low cost, high production efficiency. One of the main reasons for this is the widely used to live. The basic principle and the classification of the shot-blasting machine, the new shot peening technology, and carries on the elaboration and the analysis on practical application. Surface treatment of shot peening, strike force, the cleaning effect is obvious. But the shot peening of metal processing, easy to deformation of the workpiece, and shot hit the workpiece surface (either shot or shot peening) makes the metal substrate deformation, due to Fe3O4 and Fe2O3 has no plastic, after breaking off, and the oil film and the substrate with the deformation, so the workpiece with the oil, shot blasting, shot peening is not completely clear oil pollution. In the existing methods of workpiece surface processing, cleaning effect is the best number is also the blast cleaning. Sandblasting is suitable for workpiece surface requirements higher cleanup. By means of 3D modeling and theoretical calculation of Pro/e, design a set of metal surface nanocrystallization of high-energy injector, the design content including the layout and structure of the motor selection, the final rendering integrated block part drawing and assembly drawing of the system.
