Popis: | This work presents the implementation of the hot-forging process of seamless elbow fittings into a finite element model (FEM) developed with the aid of a commercial software code. The strain gradients predicted by the FEM were compared with the strain distributions computed by a visioplastic analysis. Measurements made on forged elbows are used to validate the predictions of the FEM. Once the validation was successful, the FEM is used to evaluate the effect that the tooling design exerts on the final dimensions and characteristics of formed elbows; this was done by changing the design of the tooling (mandrel). Two critical characteristics are required in forged elbows; these are consistency in wall thickness and length of the external arc, as wall consistency is directly associated with product quality, whereas control on the length contributes to savings in raw material. Results found by the FEM allows the conclusion that these characteristics are related to each other. |
