Splitting Process

Abstract This paper are presented the results of theoretical and experimental research on splitting without waste of pipe billets from aluminium alloy realized basing on cross-wedge rolling method. The analyzed process is connected with rolling of a V-shape groove on a split billet circumference, and later with rotary bending causing material separation. In theoretical analysis, based on simulations by means of finite element method, basic models of metal cracking (brittle and ductile) were applied. During calculations, the following process parameters were changed: forming angle α, bending angle θ and reduction ratio ∆r. The achieved results allowed for a precise analysis of the splitting process within the scope of: state of strain, kinematics of flow, force parameters, state of stresses and type of cracking of the split material. On the basis of experimental research, the influence of the analyzed parameters on the surface of splitting was estimated and scope of parameters guaranteeing the assumed quality of the product was given. The comparison of theoretical and experimental results showed good conformity.
