摘要：提出了一种新型双金属复合管生产工艺-热液压工艺,并根据该工艺设计出了热液压实验装置。经过理论分析,基于部分假设条件,得出了最终残余接触压力和内压力以及有效温差的关系,并给出了有效温差的求解途径。通过20/316L钢的复合管冷/热液压成形对比实验,验证了理论的可靠性和热液压工艺的可行性。结果表明,热液压工艺能够实现传统工艺无法实现的“外弱内强”型复合管胀合。该理论能够指导复合管工业生产。
A new bimetallic composite tube production process-thermal hydraulic technology was proposed. According to this process, a hot hydraulic experimental device was designed. Based on partial assumptions, the relationships between the final residual contact pressure and the internal pressure, the effective temperature difference were obtained by the theoretical analysis. And the solution of effective temperature difference was given. The reliability of the theory and the feasibility of hot hydraulic process were verified by the comparative experiments of cold/hot hydro-forming of 20/316L steel composite pipe.The results show that the thermal hydraulic technology can realize the expansion and closing of the "external weak internal strong" type composite tube which can not be realized by the traditional technology. This theory can guide the industrial production of the composite pipe.
