摘要
针对深孔加工过程中的排屑难问题,在分析现有负压系统理论的基础上,设计多级曲面负压抽屑系统,研究其工作效率与负压喷射系数及喷射间隙倾斜角度之间的关系,从理论上推导并证明其工作效率优于传统负压抽屑装置,建立仿真模型,并利用ANSYS FLUENT软件对其进行仿真分析,多级曲面负压抽屑系统能够很好的降低了切削液的入口压力,大大提高了工作效率,实现了高效排屑的目的。
For chip removal problems during the deep hole processing, on the basis of analysis of the existing negative pressure chip pumping theory, we design the multiple surfaces negative pressure chip pumping. Study the relationship between the efficiency and negative pressure injection coefficient and negative pressure suction jet clearance inclination angle. Theoretically proved that its efficiency is better than the traditional one. Create a simulation model, and we do the fluid pressure simulation analysis for it by the ANSYS FLUENT, it can reduce inlet pressure of the cutting fluid obviously, improving the work efficiency greatly, and we achieve the purpose of efficient chip removal.
