Abstract
An Optimization Study for Bridge Design of a Porthole Extrusion Die
Highlights
Aluminum is the second most plentiful metallic element and has great attention from many field of industry because of its superior properties such as recyclability, corrosion resistance, high specific strength and especially for its light weight
The design phase is generally based on a trial and error method and which is an unefficient way in terms of time and the amount of scrap
The stress distribution is an important parameter for determining the service life of the die because of affecting the wear of a die
Summary
Aluminum is the second most plentiful metallic element and has great attention from many field of industry because of its superior properties such as recyclability, corrosion resistance, high specific strength and especially for its light weight. Hot extrusion method is a useful tool to obtain complicated profiles with high productivity and porthole dies are generally preferred for this purpose. Qamar et al [1] studied possible die defects and die correction operations for metal extrusion. They proposed a list of definitions for die defects and their preventive measures and die correction methods. In order to eliminate trial and error method, finite element based softwares have been getting used more often in the last decade. The goal of using FEM simulations is simulations is to predict the temperature distribution, exit velocity of extruded product, material flow and the tool deformation
