工字形截面锻件可以有效提高锻件强度、韧性和材料利用率。在其成形过程中,工艺参数选取不当会使锻件产生流线缺陷。针对工字形截面锻件成形缺陷,采用田口设计及计算机模拟相结合方法对锻件成形过程进行了优化。通过信噪比分析得出了最优参数组合。最后,通过生产试验对所得优化参数组合进行了验证。 I-shaped cross-section forgings can effectively improve forging strength, toughness and material utilization. In its forming process, improper selection of process parameters will produce streamline defects forgings. Aiming at the defects of the I-shaped forgings, the forming process of the forgings was optimized by Taguchi design and computer simulation. Through the analysis of signal to noise ratio, the optimal combination of parameters is obtained. Finally, the optimized combination of parameters was verified by production test.
