Abstract：

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.
