Extrusion Forming Process and Die Optimizing for Titanium Alloy Taper

In order to realize the forming of a titanium alloy taper,direct extrusion forming process,two-stage extrusion forming process and composite extrusion forming process were designed.The forming loads and production efficiency were contrasted by analysis of Deform finite element software.The best extrusion forming process was selected.The results show that: in the direct extrusion forming process,the maximum load is 11.5MN;in the two-stage extrusion forming process,the maximum load is only 4.25MN,but it has a poorer effectiveness for two-stage forming process;in the composite extrusion forming process,the maximum load is only 38.6% of direct forming process,and it has a higher effectiveness for one-stage forming process.
