Influence Rules of Technological Parameters on End Quality in Closed Cross Wedge Rolling (CWR)

Abstract:

In order to raise the efficience of materials' utilization and realize the CWR without the stub bar, this paper will focus on the closed CWR forming shafts,applying finite element software DEFORM-3D to do numerical simulation calculation for the process and studying the end quality of shafts.This paper has obtained the influence rule of the forming angle α, broadening angle β, reduction of area ψ and billet diameter D four process parameters on the end quality of the closed type CWR .The research results has showed that the length of concavity goes up along with the forming angle decrease;the same as the broadening angle; while the length of concavity goes up along with the billet diameter increase.and the reduction of area ψ has made a vital influence on the end quality of shafts,this conclusion has made a solid theoretical foundation and referential value for closed CWR .
