Abstract：

The influences of the extrusion velocity, extrusion temperature and extrusion die radius on the forming quality of extrusion parts during extrusion process were studied. The finite element model of the hot extrusion for copper alloy C10100 was established by the FEM software Deform-2D. According to its mathematical model, the rheological property of the blank was selected from database. The differences between the equivalent strain and the maximum extrusion stress were compared under the different technological parameters such as the extrusion velocity 40, 50, 60 mm·s-1, the extrusion temperature 850, 900, 950 ℃ and the radius of extrusion die 10,15,20,25 mm respectively. The study results show that the surface finished and structure of extrusion tube can meet the demands of engineering applications when the optimal parameters are chosen as the extrusion velocity 50 mm·s-1, the extrusion temperature 950 ℃ and the extrusion die radius 10 mm.
