| 分析了精冲模具间隙和断面质量并制订了间隙列线图，论述了模具加工过程的刃口尺寸控制方法及技术要求，归纳了精冲模具间隙与刃口尺寸公差的确定原则，改善了制造效果，并介绍了降低成本及缩短生产周期和简化生产工艺，提出了较详尽的精冲模具刃口尺寸公差的确定方法。 |
| 英文摘要: |
| This paper analysed the fineblanking die clearance and section quality and lay down the arrangement lines figure of the clearance. The control methods and technical specification of the edge size for the die machining process were discussed. The principles to determine properly the size and tolerance of fineblanking die edge and clearance were included. The machining result was improved. The reducing cost and shortening production cycle and simplifying process were introduced. The method to determine the size and tolerance of fineblanking die edge was presented in detail. |
