铝合金筒形机匣等温精锻技术研究

RESEARCH ON THE ISOTHERMAL PRECISION FORGING PROCESS OF ALUMINIUM ALLOY CYLINDRICAL HOUSING

在筒形机匣研制过程中，作者进行了全面的理论分析和大量的工艺试验。本文重点介绍筒形机匣成形工艺方案的确定、模具结构及分模方案的制定，精锻时加热问题的研究及有关工艺措施等技术问题。这些对铝合金等温精锻工艺具有一定的理论意义和广泛的指导意义。

a lot of theoretical analysis and repeated experience are canied out in the study of the forging process of cylindrical housing Some important SETPs during the process are introduced in the paper They include the determination of the forging process,structure of the die and location of the die parting surface The heating problem and the plastic pad which can avoid the raising of the die are introduced in the paper,too These have special significance in the precision forging process of aluminium-alloy
