| Abstract: | The difficulties in process technology of fitting manufacturing is forming of large diameter extrusion tee, which drawing process of branch pipe is the key procedure of the final forming of tee. In this paper, FEM simulation and experimental study are applied to drawing procedure of branch pipe of the hot extrusion forming process of large diameter high grade steel (X80) Φ508mm equal diameter tee. First, through numerical simulation, drawing pass and forming load is analyzed, reasonable process parameters was determined. Finally, the result of numerical simulation is verified by experiment Research result is of significance and guiding roles in actual design and production. |
