摘要
Aluminum extrusion and mold design are the guarantee of product quality, production time shortening, and die life enhancement. With increasing varieties of aluminum products for aviation, railway, and transportation, aluminum has been urgently demanded in various industries. It becomes the immediate need for the development of current aluminum extrusion to improve traditional mold design by applying DEFORM-3D simulation to accelerate product development, reduce development risks, and enhance product quality. This study attempts to process thin-layer aluminum products with extrusion. The products, in the simulation, are not easily welded when extruding the material into the welding chamber to affect the successive forming analysis. By matching pre-forming, the simulation is completed with 2 passes, and the forging information, which could not be measured in the field extrusion, such as stress value, strain value, and velocity field, could be acquired in the analysis result. After evaluating the practicability of product size requirement and pre-forming design, it could be introduced to the mechanical production. In addition to be the optimal parameters for mold design and the comparison with actual products and simulation data, the accuracy of the theoretical model is verified to shorten the product development time and reduce the cost to promote the competitiveness of the entire industry.
