摘要：

介绍了一种新型铝合金管路快卸卡箍柔性连接的结构形式，通过开展管材性能参数测试、五柱六槽管端滚压连接工艺建模、工艺仿真和工艺试验，探究了扭矩等工艺参数对于滚压连接成形质量的影响规律，确定了大直径铝合金管端滚压连接工艺参数。结果表明：扭矩与管套凹槽的填充率成正比，扭矩过小，管套凹槽填充不足，扭矩过大，导管材料填充完管套凹槽后会继续伸长，在实际生产中应将扭矩控制在合理范围。研制的铝合金管路快卸卡箍柔性连接导管组件通过了性能考核试验，验证了快卸卡箍柔性连接结构的可行性和可靠性，为后续工程化应用奠定了基础。

A new structural form of flexible connection for aluminum alloy pipeline quick-release clamp was introduced. Then, through the test of pipe performance parameters, modeling of five-column and six-groove pipe end rolling connection process, process simulation and process test, the influence law of process parameters such as torque on the forming quality of rolling connection was explored, and the process parameters of rolling connection for large diameter aluminum alloy pipe end were determined. The results show that the torque is proportional to the filling rate of pipe sleeve groove. If the torque is too small, the pipe sleeve groove is filled insufficient. If the torque is too large, the pipe material continues to elongate after filling the pipe sleeve groove, so the torque should be controlled within a reasonable range in the actual production. The developed flexible connecting pipe assembly of aluminum alloy pipeline quick-release clamp passes the performance assessment test, which verifies the feasibility and reliability of the quick-release clamp flexible connecting structure and lays the foundation for subsequent engineering application.
