摘　　要：对大型块类锻件工装吊卡的锻造工艺方案进行对比分析,提出采用钢锭墩粗、拔长工艺,保证锻件内部充分变形,再利用局部墩粗工艺,达到中间方块的锻出条件,最后采取冲孔成型的锻造工艺。经生产验证,锻件达到了设计要求。较自由锻工艺,锻件最大减重达31.7%。By comparing and analyzing the forging process schemes of large block forgings,it is proposed to adopt the technology of upsetting and drawing out ingot to ensure the full deformation of the forgings inner,and then use the local upsetting technology to reach the finished forging condition of the middle block,and finally adopt the forging process of punching forming.After production verification,the forgings meet the design requirements.Compared with the free forging process,the maximum weight reduction for forging is 31.7%.

关 键 词：块类锻件 局部墩粗 胎模锻
