摘要
介绍了高强板大梁成形工艺和产生的问题,对原工艺方案、拉深造型及模具结构进行了模拟、优化,解决了制件的壁厚减薄及回弹变形等问题,制件合格率达95%以上。
According to the problem in forming process of high strength steel girder, the forming process, drawing modeling and die structure were simulated and optimized. Finally, the problem of serious thinning and spring back of girder was solved. The quality rate of products was extremely improved.
