PROBLEM TO BE SOLVED: To provide a pipe bending device capable of simplifying a structure, and decreasing size.SOLUTION: A pipe bending device 1 for bending a pipe 15 has a pressure die 6 which pressurizes an outer periphery of the pipe 15 and moves backward/forward in a pipe axis L direction of the pipe 15; a bending die 7 which rotates while gripping the pipe 15, and cooperates with the pressure die 6 to bend the pipe 15; a pinion gear 25 which rotates in linkage with the bending die 7; a rack 26 which extends in the pipe axis L to be provided on the pressure die 6, and moves backward/forward in linkage with rotations of the pinion gear 25; and a driving portion 2 which rotation-drives the bending die 7.SELECTED DRAWING: Figure 1 |
