Modeling of Aluminum Profile Extrusion Yield: Online Billet Cutting

The mathematic model of three-dimensional aluminum profile extrusion processes using finite volume method (FVM) was established in this paper. Basic theory and key technologies of this model were researched and built. Non-orthogonal blocked structured girds were used to fit complex geometries. Volume of Fluid (VOF) scheme was used to capture the free surface of the deforming materials. A program AE-FVM was written according to the above theories and equations. A thin walled aluminum profile extrusion process was simulated and optimized using AE-FVM. The simulation results were also compared with that simulated by Deform-3D and SuperForge in the same conditions. The feasibility of the mathematic model built in this paper was demonstrated by the simulation results comparison.

Aluminum Profile Extrusion

Aiming at the aluminum profile extrusion process of a large caliber aluminum tube with porthole die, this paper established the simulation models by using finite element method and finite volume method, respectively. The extrusion process was simulated by using the above two models. The advantages and disadvantages and the applicability of the two simulation methods in simulating large aluminum profile extrusion processes were compared. It is concluded that finite volume method is more suitable than finite element method for simulating aluminum profile extrusion processes with a severe deformation. In addition, the distributions of stress and strain and the material flow patterns in the large caliber aluminum tube extrusion process with porthole die were given in detail. The results can provide useful theoretical guidelines for the process and die design as well as process parameter optimal selection for large aluminum profile extrusion processes with porthole die.

Aluminum Profile Extrusion

Extrusion process of a large diameter thin-walled aluminum profile was simulated by Arbitrary Lagrangian Eulerian (ALE) algorithm based on HyperXtrude software. The results show that the material flow velocity in the bearing exit of the initial design die is non-uniform. Three times modifications were performed and simulated. The optimal design with more uniform flow velocity in the bearing exit was obtained.

According to the similar characteristics of structure, geometry and constraints conditions in the same type of extrusion process, the intelligent design system of a square tube aluminum profile extrusion forming process was established in this paper based on the VB programming language, with using parametric programming language APDL provides by ANSYS software. The parameterized optimization design plan of pre-treatment and post-processing of ANSYS analysis during a square tube aluminum extrusion forming process was achieved, and the program of a three-dimensional model of the extrusion die under Visual Lisp environment was also programmed. The human-computer interaction intelligent design system which combined with pre-processing of semi-finished product, finite element analysis of extrusion die strength, extrusion die temperature field analysis, structural optimization of the die was realized. The research results show that the system can provide program decision-making, structural design, performance analysis and graphics treatment for the actual extrusion productions of square tube aluminum extrusion process, which reduced the design time of the technical staff, and saved design cost.
