The invention discloses a pipe bending machine capable of displaying a bending angle. The pipe bending machine capable of displaying the bending angle comprises a workbench. A rotating shaft, a pipe bending mechanism, a conveyor and a limiting mechanism are fixedly installed at the upper end of the workbench. A bearing is fixedly connected with the side wall of the portion, close to the top end, of the rotating shaft in a sleeving mode. A sleeve is fixedly connected with the annular outer side wall of the bearing in a sleeving mode, and the two ends of the sleeve are opened. A pointer is fixedly connected with the top of the sleeve, a dial is fixedly connected with the upper end of the rotating shaft, and the pointing end of the pointer points to the dial. An annular extrusion groove is formed in the annular side wall of the sleeve, and clamping mechanisms are oppositely arranged on the corresponding groove walls of the extrusion groove. The pipe bending mechanism comprises a fixing base. The fixing base is fixedly connected to the upper end of the workbench, and a hydraulic pump is fixedly connected with the upper end of the fixing base. According to the pipe bending machine capable of displaying the bending angle, the pipeline bending angle which is formed after the pipe bending machine processes a pipeline is obtained through the display of the pointer on the dial, and the pipeline is firmly pressed through adjustment of the position of a limiting plate.
