Reliability Analysis and Experimental Research on Cutting Tool of Vertical Shearing Machine

Article Preview

Abstract:

The failure cause and failure mode of cutting tool is analyzed based on the reliability analysis on cutting tool of vertical shearing machine. Reliability calculation model is established, and experimental research on cutting tool is operated. The results show that the critical failure mode of cutting tool is electric die grinder .The crucial failure cause is that in the shearing process, the UO2 ceramic in the fuel components is crushed into particles with high hardness, these hard material will lead to tool wear. The reliability of cutting tool is 0.892, which cant achieve the spent fuel reprocessing working shearing machine reliability requirements. The structure and materials of cutting tool must be improved. The parallel distance between the upper surface of cutting tool and the lower surface of the pressing block has to be adjusted.
