6061高强度铝合金拉深工艺参数优化

Optimization of drawing parameters for 6061 high strength aluminum alloy

基于DynaForm对6061高强度铝合金板料拉深成形过程进行仿真模拟,通过设计正交试验,研究在不同温度、压边力、冲压速度下的拉深件成形质量,采用极差与方差分析了3个工艺参数的影响程度,并对该影响因素进行了优化分析。研究结果表明:最佳的成形工艺参数为,400℃的试验温度、8 kN的压边力和4 mm/s的冲压速度。

Based on the DynaForm software,the drawing process of 6061 high-strength aluminum alloy sheet was simulated.Through the orthogonal experiments,the drawing quality of the sheet at different temperatures,blank holder forces,and stamping speeds was studied.With range and variance method,the influence degree of three process parameters was analyzed,and the influence factors were optimized.The results showed that the aluminum sheet has the best forming performance under the conditions of the experimental temperature of 400℃,the blank holder force of 8 kN and the stamping speed of 20%.
