Deform Based 1Cr18Ni9Ti Pipe Joint Upsetting Extrusion Process Finite Element Numerical Simulation Analysis

Abstract

Internal Defects are more likely to occur when 1Cr18Ni9Ti pipe joint are produced by traditional casting method or welding forming method, while the upsetting extrusion proposed in this essay can not only meet the part quality requirements, but also save material and shorten processing cycle. By numerical simulation analysis about part upsetting extrusion forming process with the finite element analysis method, we can obtain many index numerical values in part forming process, and therefore provide reliable quantitative basis for optimum design.
