摘要
运用数值模拟技术和闭塞成形工艺对零件进行了变形规律的研究与分析。通过理论研究与实践证明,采用闭塞成形技术完全可以实现零件的精密径向挤压成形。在成形过程中工件流动性好,挤压力低,尺寸精度高,产品质量好,同时生产效率也大大提高。与传统方法相比具有显著的技术优势和制造成本优势。
The metal forming is studied to the clutch disc hub by numerical simulation and closed precision forming tech- nology. The theory research and practice show that the precision radial extrusion of the clutch disc hub can he realized by closed precision forming technology. The part is formed with good formability, small extrusion force, high accuracy, good quality, and the production efficiency is improved largely. It gains the upper hand in technology and manufacturing cost with conven tional methods and is important to improve the production technology and quality.
