Metal pipe bending machine

The invention discloses a metal pipe bending machine which comprises a fixing frame, a conveying assembly is arranged on the right side of the fixing frame, a hydraulic rod is fixedly connected to the inner top of the fixing frame, a rectangular plate is fixedly connected to the telescopic end of the hydraulic rod, and a plurality of connecting rods are fixedly connected to the lower end of the rectangular plate; the telescopic ends of every two matched connecting rods are jointly and fixedly connected with a transverse box, sleeving assemblies are arranged at the lower ends of the two transverse boxes, and the inner wall of the rear side of the fixing frame is fixedly connected with a short rod. According to the pipe bending machine, in the machining process, feeding and discharging can be automatically conducted, the situation that a pipe is hung on a bending block and cannot fall off in the discharging process can be avoided through the arrangement of the pushing assembly, meanwhile, the position of the pi
