The present invention relates to a pipe bending machine for bending a pipe inserted into a mandrel, comprising: a fixing and supporting unit having a bending groove on which a pipe is mounted; a first supporting unit arranged on the front of the fixing and supporting unit, and prepared to be displaced forwards and backwards toward the fixing and supporting unit; a second supporting unit arranged on a side of the first supporting unit, and prepared to be displaced forwards and backwards toward the pipe inserted into the mandrel; a supporting plate, in which the fixing and supporting unit and the first supporting unit are installed to be rotated; and a control unit for controlling the operation of the first supporting unit, the second supporting unit, and the supporting plate. The supporting plate is prepared to be displaced in a length direction of the pipe before being bent by the control unit. Accordingly, a pipe bending process can be used easily, and ��shaped pipe bending, which requires bending to be performed twice, can be realized in one process cycle. Various types of pipe bending processes can be easily realized by freely controlling the width of the bending part according to choice. Moreover, the productivity is improved by realizing the fast working speed of the bending process, and the bending work can be performed in a relatively narrow space. |
