摘要:

 借助Deform有限元数值模拟软件,针对平板锻件在生产制造时容易出现飞边过大且四角缺料等锻造缺陷问题,通过在锻模型腔飞边桥四周增设截面直径为Φ5 mm的半圆形阻力槽和不增设阻力槽的两种对照设计方案,依据金属材料流动规律及载荷模拟仿真结果, 分别对平板成形模拟结果和载荷情况进行模拟分析。并进行了通过实际生产验证,在锻模型腔四周增加了截面直径为Φ5 mm的半圆形阻力槽后,可以显著优化锻模型腔结构,锻件合格率由81.7%提高至97.9%,不仅保证了难度较高的锻模型腔四角充填工艺的质量,而且还减小了飞边和坯料下料尺寸,材料利用率提高了6.9%。

 

?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%.
