摘要
针对厚板精密冲裁过程存在的缺陷(塌角与毛刺等),基于Deformed2D分析了10mm厚钢板精密冲裁过程中双齿V形压料板对冲裁质量的影响。采用V形压料板可在一定程度上减小塌角的高度,但不能完全消除。随后采用精冲挤压方法对这一厚板的成形过程进行了分析,结果表明:采用精冲挤压成形工艺后,厚板零件表面塌角得到了完全消除,零件质量得到提高。
Collapse and burr are main defects during thick plate fine-blanking process. The effects of double teeth v-shaped pressure stripper plate on cutting quality during 10turn thick plate fine-blanking process have been analyzed based on Deformed2D simulation. It shows that the height of collapse angle has been reduced by use of double teeth v-shaped pressure stripper plate, but not been completely eliminated. Then, the forming process of fine-blanking and extrusion on thick plate has been analyzed. It shows that the collapse of part has been eliminated completely by adopting fine-blanking and extrusion process, and the quality of part has been improved.
