| 目的 研究冲裁间隙、凸模刃口圆角和斜刃角度等因素对厚板冲裁断面质量及冲裁力的影响规律，优化冲裁工艺参数组合。方法 通过数值模拟和正交试验设计相结合的方法，以冲裁过程中相对光亮带长度和最大冲裁力作为评价指标，对板厚t=10 mm的60Si2Mn厚板进行冲裁过程的模拟仿真，最后进行工艺试验。结果 选取了合理的工艺参数组合：冲裁间隙为10%t，圆角半径为0.1 mm，斜刃角度为6°，利用此工艺参数组合模拟得到了较好的断面质量及较小的冲裁力，工艺试验也验证了此工艺参数的合理性。结论 通过模拟得到的工艺参数是合理的，对实际生产有重要的指导作用。 |

| The paper aims to study influences of blanking clearance, fillet radius of punch and angle of beveled punch on blanking quality and blanking force of thick plate and to select the reasonable combination of blanking process parameters. Numerical simulation and orthogonal experiment design were combined. With the length of relative bright belt and the maximum blanking force as evaluation indexes, the blanking process for 10 mm thick 60Si2Mn plate was numerically simulated, and the process experiment was carried out in the end. Reasonable combination of process parameters was selected: blanking clearance of 10%t, radius of 0.1 mm, beveled punch angle of 6°. Better cross-section quality and smaller blanking force were obtained with the process parameter combination. The process experiment also verified the rationality of these process parameters. The process parameters obtained by simulation are reasonable and the result is an important guidance for practical production in enterprises. |
