| 中文摘要: |
| 通过对带有裂纹毛坯成形过程的分析,找出了造成缺陷成因,并通过验证试验证明,造成问题的原因是工件的加热温度过高及第 1 道变薄拉深前退火不完全共同作用导致的,并针对工艺中存在的问题提出解决问题的具体办法,对工艺过程进行了完善。 |
| 英文摘要: |
| Through analyzing the cause of cracks produced during ironing process and conducting test, this paper gives the cause of cracks which is due to excessively high temperature and incomplete annealing before the first ironing procedure. It also puts forward some specific measures in view of the deficiency in process to solve this problem. The process is also improved. |
