ABSTRACT:
A tube bending system for bending all tubes in a preset manner effectively from the beginning of works by detecting a degree of bending of a tube which varies during a bending process in high precision by a displacement sensor and by accurately comparing the detected value of the degree of bending of the tube detected by the displacement sensor with a control value written in advance in a program in a memory. The displacement sensor is disposed so as to be able to detect the position of the tube to be bent on the side of a reaction receiving section between a gripper and the reaction receiving section. The displacement sensor is composed of a detecting section and a transducing section. A value which indicates the position of the tube to be bent detected by the detecting section is transduced to a degree of bending of the tube to be bent by the transducing section and the transduced degree of bending is transmitted to a controller during repetitive operation for bending the tube so that the degree of bending approaches to the predetermined degree of bending.
