Abstract:

The process optimization of automobile accumulator shell extrusion forming was conducted with numerical simulation based on Deform-3 D software platform. The orthogonal test plan was set up and the effects of various factors on the extrusion forming process were analyzed, then the best process parameters were determinded with the forming load as judging standard. The best process parameters finally obtained : mold temperature 230℃,blank temperature 1000℃,friction coefficient 0.15, punch velocity 12mm·s-1 for warm extrusion,and punch velocity 8mm·s-1, friction coefficient 0.08 for cold extrusion. The qualified forming parts were obtained from actual extrusion with the parameters.
