Abstract：

The forming process of DFL350 piston head is analyzed and a warm extrusion die is designed.A three dimension finite element modal based on Deform-3D has been established.The forming process is performed and the influences of the temperature,friction factor,draft angle and die cavity on load and die cavity filling are analyzed and discussed.The damage factor distribution and the load-stroke curve for optimized process and die design are achieved.On the basis of the simulation,the suitable parameter selection,die design and equipment selection are given for the warm extrusion of DFL350 piston head.
