Abstract：

Reducing the thinning ratio in stamping of continuous rectangular boxes wall plate is very important to improve its depth and structure efficiency. The representative double\|six rectangular boxes of 5A06 aluminum alloy was used in the stamping test, the forming process was simulated by ABAQUS, and the flow characteristics of material in forming process was analysed by comparing them. The structural design requirements and lubricant methods of reducing the thinning ratio were mentioned, especially for the corner radius and lubrication at the bottom of punch. The results show that when using the radius of corner from the results of FEM, no friction condition at the punch bottom and the effect of forming can be the best. These analysis methods and conclusions have been applied to the design of engineering products, and achieved good results.
