摘　　要：为获得满足功能要求的智慧路灯用冷弯异型钢管,采用整体轧辊,通过改变不同轧制部位孔型的曲率半径,经过28道次轧制实现了双凹槽异型钢管的成型,成型过程中穿插安装立辊辅佐变形,最后通过焊接生产出符合要求的产品。使用整体轧辊成型方法能以较少轧制道次生产出符合要求的异型钢管,适合批量生产;一套轧辊可覆盖所有规格的异型钢管产品,轧辊共用率高;成型辊耗小、稳定性高,可应用于诸多异型钢管的生产。In order to obtain the cold-bending special-shaped steel pipe for smart streetlight that meets the functional requirements, the overall roll is adopted. By changing the curvature radius of different parts, the forming of double groove special-shaped steel pipe is realized after 28 passes. In the forming process, the vertical roll is inserted to assist the deformation. Finally, the products that meet the requirements are produced by welding. Using the overall roll forming method,the special-shaped steel pipe meeting the requirements can be produced with fewer passes, which is suitable for mass production. One set of rolls can cover all specifications of structural steel products, with high roll sharing rate. The forming roller has low consumption and high stability, and can be applied to the production of many special section tubes.
