Simulation And Optimum Design Of Porthole Die For Aluminum Profile

Alloy profile of square is analyzed. The porthole die by using SolidWorks are designed and the protrusion by using Deform-3D are simulated. The data of simulation are obtained, at last the optimization design of the porthole die are gained.Design steps of the porthole die and effect of the structure parameters to the protrusion process are introduced.By using Gleeble-1500 thermomechanical simulator, compressed tests of aluminum alloy are made in certain temperature, at certain strain rate and strain, the true stress-strain curve and equation of 6063 aluminum alloy are gained.By the method of orthogonal experiment, the optimum technical parameters are selected, which are inside slope, outside slope and depth of the weld-chamber. By using Deform-3D, the effect stress of the porthole and mean stress of the weld-chamber are analyzed. Based on the above, the measures to improve the design of porthole die are proposed.
