Two flaws of a forging front axle of heavy truck in process debugging of precision roll-forging, which are fold in transitional section between spring seat and I-beam and under-filling of I-beam, were studied. First, a novel die construction of side roll-forging was proposed to solve the fold problem by matching roll-forging grooves reasonably. Then, the three main variables for forming of the I-beam, namely B, R and A of the roll-forging die in the third step were analyzed to eliminate the I-beam under-filling defect. The effecting mechanism of the three parameters on the forging quality was investigated by numerical simulation based on the orthogonal experimental design methods. The optimal values for B, R and A are 23 mm, 28 mm and 18°, respectively. The productive results show that the stability of the roll-forging process is realized and the finial products with required quality are approached. In addition, the material utilization rate reaches 90%. This study offers knowledge for the forming of similar products.
