摘　　要：以某机第八级机匣热屏蔽环为研究对象,对其进行结构分析、刚模胀形工艺分析,探讨了冲压胀形前的毛坯尺寸确定、分体凹模的胀形模具的结构设计。通过对胀形过程中毛料成形特点分析,并结合通用冲压设备的实际工况,摸索类似零件的成形方法,解决了薄壁筒体带环筋和端部收口零件的一次冲压成形问题。模具经过现场调试,完成了制件的研制加工。方案对大幅降低模具成本、提高毛料利用率和生产效率具有很好的指导意义。A research based on the heat barrier ring of some eighth casing has been established which presents an approach of how to confirm the dimensions before stamping and expanding, and the structure design of expanding for split concave forming die by analyzing the structure of heat barrier ring and expanding workmanship of rigid die.An issue emerged during one-step forming for thin shell with stiffening ring and component with necking at one end has been solved by analyzing the characteristics of stock during the expanding, besides considering the actual conditions of general stamping machine and methods applied to similar parts.The researching manufacture of product has been finished after debugging the forming die based on above analysis which results in swinging cuts on cost of forming die and improving the rate of utilizing stocks and production efficiency.
