Abstract
In shape rolling process, the definition of roll pass and profile design is important. For the prediction of workpiece sectional shape, for some rod rolling passes, an analytical model by Shinokura and Takai was proposed and verified. The application of FE techniques to the rod rolling process lets to study some other passes with much simplicity. In this paper, for round-flat oval pass and round-flat pass, in rebar rolling, the experimental values of maximum spread and of radius of the rebar have been carried out and compared with the results of the analytical model and of the FEM analysis. The FE model has been developed with MSC.Marc Autoforge program, a FE non-linear solver, dedicated to simulate plastic strain working.File | Dimensione | Formato | |
