Article Preview

In the paper, the Deform-3D software was used to simulate the mechanism of metal flow behaviour under the influence of different friction in the backward extrusion process, and further study its influence on die stress. The numerical simulation demonstrates that: smaller friction could reduce difficult deformation area of extrusion metal significantly; friction state not only affected the plastic deformation extent, but also would increase the consumption of extrusion energy; the unit pressure of punch and stress of inner wall increased along with the increase of friction, meanwhile, the ratio of them increased as well.
