Claims

[Scope of utility model registration request]

In a pipe bending apparatus, a bend die is fixed on a base, and a lift table that is driven up and down above the base is provided with a bend punch for pressing the pipe along the bend die. A cam having an inclined cam surface on the lower surface is supported on the fixed support so as to be movable in the horizontal direction, and the cam has an inclined sliding surface on the upper surface corresponding to the cam surface and the direction of movement of the cam. A holder that is movable up and down while being prevented from moving upwardly is fitted to the cam with its sliding surface in sliding contact with the cam surface, and the bend punch, which has a groove on its lower surface corresponding to the upper surface of the pipe, is aligned with the axis of the pipe. A pipe bending device, wherein the pipe bending device is supported by the holder so as to be swingable around orthogonal horizontal axes, and the support body is provided with a cam feeding mechanism.
