PROBLEM TO BE SOLVED: To provide a pipe bending processing unit in a pipe bending processing device which is compact and easy to control. SOLUTION: The pipe bending unit 10 in the pipe bending processing device is equipped with a bending roll 11, a clamp 12 for fixing a pipe to the bending roll, a presser 13 for bending the pipe by moving along the bending roll while pressing the pipe to the bending roll. In the pipe bending processing unit in the pipe bending processing device, a fixed plate 14 having cams 15, 16 for the presser for attachably and detachably supporting the clamp 12 against the bending roll 11 and determining the moving track of the presser 13 is disposed. A rotary plate 17 having cams 20, 21 for the clamp for supporting the presser 13 in contact with and separable from the bending roll 11 and moving the clamp 12 is disposed. The clamp 12 and the presser 13 are operated by these cams. COPYRIGHT: (C)2004,JPO
