Dynamic Strength Analysis And Structural Optimization Of Rough Machining Tool In Machining Large Forging

Heavy duty cutting mainly considers: improving the machining efficiency,utilization rate of equipment, reducing energy consumption. With the development ofpetrochemical industry, the materials of hydrogenation reactor constantly updated,more and more large size, to achieve the above three requirements, a higher degree ofdifficulty for heavy-duty tool. So the study of heavy-duty cutting structure, materialselection, cutting tool’s strength and physical distribution in revealing the basic lawsof heavy cutting has great theoretical value and practical significance. In this paper,the following studies are done:First, separate statistics are done on the rough surface of the cylindrical shell harshconditions in the processing site, The actual processing of cylindrical shell’s roughmachining in the factory is tracked, analyzing extrinsic and intrinsic factors of toolpremature breakage, optimization scheme was provided for the subsequent blade.Inrequirements of cylindrical shell’s rough machining, different tool materials wereanalyzed, tool materials are suitably elected in rough machining technology forcylindrical Shell.Second, theoretical analysis of heavy-duty cutting intensity, the based zorev. N. N,heavy lathe tool rake face stress distribution model and the cutting process of heatconduction theory. Withstand the load of the dynamic mechanical impact and thermalshock loads on the tool of the cylindrical shell’s rough machining for analysis.Third, based on the finite element software, the study of corresponding force field,temperature field are done for heavy lathe tool structure, distribution law of the toolin the stress field, deformation and temperature in the cutting process are obtained.Fourth, for the previous structure and parameter optimization of heavy-duty tool to Solidworks secondary development of technology as basis to develop a set of lathetool blade design system.Lastly, the design of new cutting tool used for the actual processing site,comparison test with the factory blade cutting, verify the feasibility of the newstructure and parameter optimization of the blade.
