工艺参数对镀锌钢板成形性能影响的试验研究

Experiment Studying on Influence of Process Parameters of Hit dip Galvanized Steel Sheet Forming Properties

充分发挥计算机数值模拟试验与物理试验相结合的研究方法的优点 ,针对影响汽车用热镀锌钢板拉深成形性能的主要工艺参数 (凹、凸模圆角半径、压边力、摩擦系数 )进行正交试验 ,得出该 4种工艺参数对汽车用热镀锌钢板成形性能影响的显著性指标 。

Taking advantage of combining numerical simulation experiment with spot experiment, orthogonal method was applied to analyzing the experiment data in this paper. Results showed that four process parameters had great effects on the forming properties of hit galvanized steel sheet during drawing. In accordance with ordering of primary and secondary, the four parameters were die edge radius、punch edge radius、drawing pressure of upper ring and drawing compound. The best combination of process parameters was made in conclusion.
