RESEARCH APPLICATION OF SIMULATION TO OPTIMIZING DIE DESIGN EXTRUSION ALUMINUM ALLOY ELECTRIC MOTOR CASE

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, 10]. 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 6063 aluminum alloy electric
motor case extrusion die design.
