| 摘要随着技术水平日渐提高，人们对与各种机械制造类产品的表面质量要求越来越高，普通材料在不进行处理的情况下很难再满足实际的应用需求，对于材料的表面处理这时就显得尤为重要，而当今最主要的表面处理手段之一就是采用抛丸机进行表面强化。就如今国内抛丸强化技术发展现状来说，对材料表面强化一般难以达到纳米级，然而当金属材料表面达到纳米级时，它的表面性能将大大提高，无论是化学性能还是其他物理性能。8093 本设计在基于如今抛丸机的基本构架的基础上，分析抛丸机的各种技术指标，设计出能对金属材料进行表面纳米化强化处理的抛丸装置，并且在现今的抛丸强化主要的还是对钢板等的处理，而对于已成型的机械的焊缝处的强化处理有所欠缺，设计出主要如对舰船船体钢板焊缝处进行表面纳米化处理得抛丸机械。 关键字：纳米化 抛丸机 弹丸 斗式提升机 毕业设计说明书（论文）外文摘要 Title The design of the hull’s welds nano-shot blasting machine and the projectile recovery systems Abstract With the rising level of technology,people are increasingly high quality requirements on surface quality of a variety of machinery products,common materials in the case of processing is difficult to satisfy the actual application requirement.It is particularly important for the surface treatment of the material,one of today’s most important means of surface treatment is the use of the shot-blasting machine for surface harding.As for the development present situation of the domestic shot-blasting strengthening technology,surface hardening of materials is generally difficult to achieve nanoscale,however,when the metal surface to achieve the nanoscale,the surface properties will greatly improve both the chemical properties and physical properties. This design is based on the basis of the framework of the shot- blasting machine.Through the analysis a variety of technical indicators of the shot-blasting machine,The design of the shot-blasting machine can enhanced the surface of metallic mayeials to nanoscale,and in today’s shot-blasting is main to strengthen the steel,but lack of enhanced treatment of the welds of molding machinery.The design is to make the ship hull steel welds’surface become nanoscale.
