摘要：

针对球头销钉球头成形困难的问题，提出一种预镦球头、终镦球头的2工位成形工艺方法，并应用有限元软件DEFORM-3D对球头成形过程进行数值仿真。分析预镦工位及终镦工位中各工艺参数对球头成形的影响，结合正交试验法，设计了以凹模圆角、锥角、摩擦系数、冲压速度、过渡圆角为试验参数的5因素4水平的正交试验，以成形过程中模具所受载荷最小为优化目标，通过极差及方差分析获得最优参数组合，即凹模圆角为0.2 mm、锥角为20°、摩擦系数为0.05、冲压速度为10 mm·s-1、过渡圆角为3 mm。最后，立足生产实际，验证仿真结果的可靠性，以在实际生产中能够有效地指导企业的生产。

For the problem of the difficulty in ball head forming of ball head pin, the two-position forming process method with pre-upsetting ball head and end-upsetting ball head was proposed, and the forming process of ball head was simulated numerically by finite element software DEFORM-3D. Then, the influences of process parameters in pre-upsetting position and end-upsetting position on ball head forming were analyzed, and combined with orthogonal experiment method, taking the die fillet, cone angle, friction coefficient, stamping speed and transition fillet as the test parameters, the orthogonal experiment with five factors and four levels was designed. Furthermore, the optimization objective was to minimize the load on die in the forming process, and the optimal combination of parameters were obtained by range analysis and variance analysis with die fillet of 0.2 mm, cone angle of 20°, friction coefficient of 0.05, stamping speed of 10 mm·s-1 and transition fillet of 3 mm. Finally, based on the actual production, the reliability of simulation results was verified which effectively guided the production of enterprises in actual production.
