PPR pipe bending device

The utility model relates to the technical field of pipe bending devices, in particular to a PPR pipe bending device which comprises a base, a pipe base is fixedly connected to the top of the base, amounting groove is formed in the back face of the base, and a connecting rod is rotatably connected to the inner wall of the mounting groove. According to the utility model, the semicircular groove seats are arranged to bend a pipe; the arc inner wall of the semicircular groove base can limit the side face of a pipe, the side face of the overturning plate is supported in a sliding mode under the sliding connection of a sliding way on the inner side of the arc rail and a sliding block, side face deviation can be avoided in the pipe bending process, and the influence of side face deviation on pipe bending is avoided. The indicator on the surface of the fixing rod is driven by the sliding block to move synchronously, scale values of the arc-shaped angle scale plate can be indicated, and therefore the bending degree o
