Zusammenfassung:An elastic—plastic finite-element analysis of a five-stage cold-heading operation is presented. This gives accurate prediction of the external shapes produced, and of the internal distortion. The method can be used to optimise preform routes with respect to maximum forces, homogeneity of the product and process costs in terms of number of stages and inter-annealing requirements.
