Bending device for hollow steel pipe

The utility model relates to the field of steel pipe bending equipment, in particular to a hollow steel pipe bending device which comprises a workbench, a feeding assembly, a traction assembly, a bending assembly and an embedding assembly, the feeding assembly, the traction assembly, the bending assembly and the embedding assembly are arranged in the conveying direction of a steel pipe, the steel pipe is fed from the feeding assembly and conveyed forwards, and the front end of the steel pipe reaches the traction assembly; the steel pipe is driven by the traction assembly and continues to be conveyed forwards, the steel pipe reaches the bending assembly under traction of the traction assembly, the embedded part is inserted into the hollow steel pipe through the embedded assembly, the inner wall of the steel pipe is supported through the embedded part, and therefore the situation that the hollow steel pipe is bent and broken is reduced. 本实用新型涉及钢管折弯设备领域，具体为一种中空钢管的弯折装置，包括工作台，沿钢管输送方向的上料组件、牵引组件、折弯组件以及内嵌组件，钢管从上料组件处进
