冲压成形中凹模入口角曲线优化
Optimization of Draw-die Entrance Curve in Sheet Metal Stamping
摘要
Abstract
During the sheet metal stamping,the shape of the draw-die entrance has an important influence on the friction between the sheet metal and die surfaces,the quality of the sheet metal sur-face and the life of tool.To get an optimal the draw-die entrance curves,a new method of using cubic spline curve as the draw-die profile was adopted.This paper investigated the effects of draw-die en-trance curves on the sheet metal tool wear distribution over the entrance of the die.With the forming quality requirements,searching for an optimal die profile was based upon response surface methodolo-gy and design of experiments.The results demonstrate that the tool wear is reduced significantly and well distributed over the entrance of the draw-die using the optimized cubic spline curve profile.As a result,the occurrence of surface defects is reduced,the quality of the sheet metal surface is increased, and the life of the tool can be extended.关键词
