【Abstract】 The effects of the hindrance angles on continuous extrusion forming of the big flakiness copper flat wire are investigated by three-dimensional finite-element technology based on software DEFORM-3D. The rigid-viscoplastic constitutive equation is employed in the model. The rules of the continuous extrusion process influenced by standard deviation of the velocity field,die load,effective strain and mean stress of the deformation body under different hindrance angles are described. The results will give effective guidelines to optimize the process parameters.更多还原
