Provided is a bending apparatus (10) for manufacturing a bent member (35) from a steel pipe (17) with high dimensional accuracy and high productivity, the apparatus being installed in a reduced space and having good maintainability. The bending apparatus has a feed mechanism (11) for feeding a steel pipe (17) in its lengthwise direction, a first support mechanism (12) for supporting the steel pipe (17) while feeding it, a heating mechanism (13) for heating a part or all of the steel pipe (17) being fed, a cooling mechanism (14) for cooling the portion of the steel pipe (17) being fed which was heated by the heating mechanism (13), a second support mechanism (25) for imparting a bending moment to the heated portion of the steel pipe (17) and thereby bending the steel pipe 17 into a desired shape by moving two-dimensionally or three-dimensionally while supporting the steel pipe (17) being fed in at least one location, and a deformation preventing mechanism (16) for preventing deformation of the steel pipe (17). The feed mechanism (11) is constituted by a first industrial robot (18) which is a vertically articulated robot having seven axes. |
