APPARATUS FOR BENDING TUBE

PROBLEM TO BE SOLVED: To provide a tube bending apparatus the actuators of which are reduced and with which a highly accurate tube is manufactured even by unskilled persons because the apparatus is easily operated by manual work. SOLUTION: In a tube bending apparatus with which a tube is restrained with a clamp and a bending die in a state where the tube is held between the groove of the bending die and the groove of a pressure and bent by turning the pressure along the peripheral surface of the bending die in that state, the bending die is movably installed so that the bending die is retreated from the bending position of the tube, the bending die is moved to the bending position interlocked with the bending action of the pressure and retreated from the bending position interlocked with the restoring action of the pressure.
