CAD system of the extrusion dies to produce aluminum profile based on UG system

LIAO Pei-gen1,FANG Gang1,ZENG Pan1,WU Xi-kun2,LIANG Yi-qing2(1.Department of Mechanical Engineering,Tsinghua University,Beijing 100084,China;2.Guangdong Xingfa Aluminium Co.,Ltd.,Fushan 528061,China)  
The great requirements for aluminum profile and variety demand higher performance of the extrusion dies as well as the shorter period of design and manufacture.The use of the CAD/CAE/CAM technology can achieve these goals.However,so far there is no CAD system which can be used to design the extrusion dies effectively.A special CAD system which embeds the engineering experience based on the UG software was developed.The system can design the bearing automatically.The finite element analyzes show that the system can improve the quality of the dies and the efficiency of the design.
