RESEARCH ON NUMERICAL SIMULATION APPLICATIONSOPTIMIZED ALUMINUM ALLOY PRODUCTS (U) EXTRUSION DIE DESIGN

Abstract

The dies an important role that directly determines the accuracy and quality
of the product in the aluminum alloy extrusion process [1,4]. To ensure the correct
geometry of the product, the exit velocity of the product at any point on the die
bearing must be equal. Therefore, the die design must ensure the balance of metal
flow out at the die bearing [3,4,6]. Aluminum alloy electric motor case made by
extrusion method is a new method that brings economic efficiency and product
quality. Numerical simulation of aluminum alloy extrusion with Qform Extrusion
software helps to accurately predict extruded product shape for each die design
option [2,5]. Thereby helping die designers calibrate design parameters to
optimize die design. This paper presents a method of applying numerical
simulation to optimize the design of extrusion die of U-shaped aluminum alloy
products, aluminum alloy material AA6063.
