通过拉深、扩孔、锥杯、凸耳等模拟成形性试验 ,全面比较了IF、 0 8Al、SPCC3种深冲钢板的成形性能。试验结果表明 ,IF板的成形性能最好 ,0 8Al板其次 ,SPCC板最低。同时 ,从力学角度分析和比较了各钢板在相应模拟试验中的成形难易程度。
The formability of three kinds of deep-drawn IF, 0 8Al and SPCC plates was comprehensively compared by simulating formability tests such as drawing, reaming, conical cup and lugs. The test results show that, IF board forming the best performance, 0 8Al board followed, SPCC board the lowest. At the same time, the forming difficulty of each steel plate in the corresponding simulation test was analyzed and compared from the mechanical point of view.
