Abstract：

?For the problems of forging defects such as excessive flash and lack of material at four corners during the production of lining plate forgings, two comparative schemes of adding a semi-circular resistance groove with cross-sectional diameter Φ5 mm and no additional resistance groove around the flash bridge of forging mold cavity were designed by finite element numerical simulation software Deform, and the simulation results of metal material flow law and load conditions were simulated and analyzed respectively. The actual production verification shows that after adding the semi-circular resistance groove with cross-sectional diameter Φ5 mm around the forging mold cavity, the structure of model cavity is significantly optimized, and the qualification rate of forgings increases from 81.7% to 97.9%, which not only guarantees the quality of four-corner filling process for more difficult mold cavity, but also reduces the sizes of flash and blank and increases the material utilization ratio by 6.9%.
