Beschreibung:
In this paper, using orthogonal design method, considering the extrusion temperature, extrusion speed, extrusion billet, die structure, which will affect the uniformity of the metal flow[1]. Using the outlet velocity average standard deviation, the average pressure and the mean maximum equivalent stress as the criterion, select the optimal process scheme of two-hole dies aluminum profile extrusion. And the optimal scheme is validated by simulation and, the results show that the extrusion velocity is uniform, no forming defects, it can stably forming. At the same time, the experiment provides theoretical guidance for real extrusion production with multi-hole dies.
