| 英文摘要: |
| The paper aims to develop a type of new multifunctional spinning equipment for the spinning forming of super-long tubes which is considered as a technical challenge. The computerized numerical control (CNC) equipment consisted of mechanical, hydraulic and electrical systems and its monolithic construction was designed as a horizontal framework which was equipped with two-lead screw drive, double spindle boxes, support device, etc. It provided important means to process super-long tubes by spinning. The spinning forming equipment for super-long tubes possessed many functions and techniques such as synchronous rotation, axial traction, floating mandrel, online detection, etc. It effectively solves defects of the bending, torsion and insufficient stiffness of super-long tubes as well as issues in manufacturing of super long mandrels. It shows significance in improving the machining accuracy and quality of super-long tubes. |
