Article Preview

A typical parameterized model of pipe axis’ secondary necking in hot extrusion process was built,and the evaluation index of forming effect was proposed. Through using revised constitutive equation in Ansys model combining the method of numerical simulation, several mainly hot extrusion process parameters’ influence on forming effect were analyzed, such as friction, temperature and extrusion speed. The prediction equation of forming effect was worked out by numerical fitting, which provided a feasible way to get the better parameters in hot extrusion process. The experiment shows that the parameters obtained from equations can have a good guide on pipe axis and also other similar workpiece’ s hot extrusion process.
