FEM-modelling of Barrel-type Cross-roll Piercing and Analysis of the Induced Rotational Motion of the Plug Bar
Original language description
Essential for the manufacturing of seamless precision steel tubes is the knowledge of the entire process chain. In regard to the cross-roll piercing procedure, the aim is to accurately predict material flow and resulting mechanical and geometrical properties of the tubular hollow. The plug guides the material flow and rotates due to friction in contact zones with the billet material. Because of elastic deflections of the rotating plug bar, the behaviour of plug bar and plug does significantly influencethe billet deformation. A gap of knowledge exists about the induced motion of the plug and, as a consequence, about the influence of its motion on the resulting properties of the tubular hollow. To simulate material flow and elastic deflections of the plug bar, a finite element model was developed using FEM-software DEFORM. Different fracture models to simulate the fracture evolution due to the Mannesmann efect were compared. Simulations without plug, and with rigid plug and plug bar, an
