CAD-Based Bit Design for Inner Wall Descaling of Water Injection Pipe

摘要：

　　Water pipeline scaling serious by prolonged use,result in a substantial diameter narrowed,reduced water efficiency.In order to solve this problem,analyzes the deposition feature and the dill descaling method,research on dill descaling theory and chip formation process.Choose multi-tooth bit as a foundation.According to the characteristics of processing object,improved the structure and cutting teeth distribution,get a new type of scaling drill.Take the inside wall of injection pipe and scale as research object,established finite element model for static analysis,get stress graph and stress curve,showed the wall stress state in drilling process.
