中文摘要: 介绍了等温超塑成形的成形效率、热效率和锻造效率以及工装和模具制造、使用寿命和效率等方面存在的问题。提出采用自动化连续上料加热系统减少热损失和设备闲置时间;使用精密组批整体成形,压机双工作平台工装拆装、加热和冷却方法提高生产效率;使用芯模加框模的设计、采用不同砂型造型并利用真空浇铸的铸造工艺等手段解决大型、特大型工装和模具浇铸成形及使用寿命的问题。最后分析了等温超塑成形的发展趋势,提出了数字化等温锻造实现的途径。
Abstract:The problems of isothermal forming efficiency, thermal efficiency, production efficiency were stated,and the problems of the manufacturing, service life, efficiency of the tooling and die were introduced. Automatic continuous feeding and heating system was proposed to use to reduce heat loss and idle time of the equipments. The integral forging for precise batch forming, assembly and disassembly, heating and cooling of tools on two platforms of press were used to improve production efficiency; and the design of core die with frame die, different sand molds and using vacuum casting process were proposed to solve the problems of the die’s casting and service life. The development trend of isothermal forming was introduced,and the way to realize digital isothermal forging was put forward.
