Technique of Forward Extrusion for Sprag
By studying material characteristics of the W6Mo5Cr4V2 and the dimension of the sprag,the die was optimized.Simulating the forming by DEFORM,the forward extrusion dies of the sprag were designed reasonably.The mold tests prove that the process is feasible.It is a conclusion that extrusion will be new processing method for W6Mo5Cr4V2.
