摘要： A tube bending system for bending a processing target tube that includes a metal tube and two flare nuts into a specific shape, with the tube bending system including a bending machine and a tube delivery unit. The tube delivery unit includes a shift-to-end mechanism that performs a shift-to-end manipulation on the processing target tube to move the two flare nuts to the end portion sides of the processing target tube such that one of the two flare nuts abuts one of the two ring-shaped projections and the other of the two flare nuts abuts the other of the two ring-shaped projections, and an inspection mechanism that utilizes the shift-to-end manipulation to detect an abnormality of the processing target tube that is to be bent in the bending machine.
