摘要
介绍了高强度钢30CrMnSiA厚板的冲裁研究,包括传统热冲裁,同步剪挤式冲裁、双间隙冲裁、齿圈压板精冲等,开展了工艺试验。结果表明,小间隙圆角刃口700℃冲裁所得到的剪切面基本都是光亮带,齿圈压板精冲可使冲裁面全部为光亮带,双间隙冲裁可使剪切面的光亮带达到50%以上。研究工作对高强度钢厚板冲裁工艺设计有一定参考价值。
The blanking research on high strength steel 30CrMnSiA thick plate was introduced,including conventional hot blanking,simultaneous shear-squeeze precision blanking,dual positive clearance blanking and fineblanking.The technological tests were carried out.The results show that the shearing surface is nearly of the burnishing zone for the small clearance-round edge blanking at 700 ℃,the shearing surface is all of the burnishing zone for the fine blanking,the burnishing zone is above 50% of the shearing surface for the dual positive clearance blanking.The research provides some new lights on the blanking design of high strength steel thick plate.
