摘要
开发了1种新型双金属复合管热液压装置制造技术,克服了双金属复合管现行制造工艺的不足,并在新技术和新装置的基础上进行了优化设计。通过理论分析阐述了热液压工艺的原理,在液压成形过程中分析了复合管和外管的应力应变,并通过热液压实验验证了理论分析的正确性。该装置成功研制了DN200(6+2)双金属CRA复合管,为大批量工业生产打下了基础。
This paper develops a new manufacturing technology of the bi-metallic liner pipe hot hydraulic device,which overcomes the shortage of the existing manufacturing process of the bimetallic liner pipe,and optimizes it on the basis of new technology and new device. Through theoretical analysis,the principle of thermal hydraulic process is expounded,and the stress and strain of liner pipe and outer tube are analyzed during hydro forming process. The correctness of theoretical analysis is verified by thermal hydraulic experiment. The DN200( 6+2) bimetallic CRA liner pipe has been successfully developed by the device,which lays a foundation for mass production of industry.
