摘要: |
通过分析某型号发动机壳体成形难点,结合我所生产实际情况,制定出新的两端缩径旋压成形工艺,即分段分模旋压成形方式,最后通过小批量生产试验验证了该工艺具有可行性和可靠性,为将来制定生产性工艺奠定了基础,也为其它类似结构发动机壳体旋压工艺的制定提供了借鉴。 |

Abstract: |
By analyzing the figuration difficulty and the actual complexion, the new process of the ports necking is established, namely subsection and multi-moulds forming mode for spinning. Furthermore, a small batch of practice experimentation demonstrates the feasibility and reliability of the process, which establishes the basic for the constitution of the production process in the future and also provides reference for constitution of spinning process of the similar structure of other engine shells. |
