Claim:
1. A pipe bender, comprising: a) a base; b) a frame, the frame comprising a position switching mechanism and a first position switching assembly; c) a calibration device; d) a feeding device; e) a cutting device; f) a feeding path; g) a bending device comprising a bending stand, the bending stand comprising a second position switching assembly; and h) a controller; wherein: the frame is fixed on the base; the calibration device and the feeding device are disposed on and supported by the frame; the cutting device, the bending device, and the controller are disposed on and supported by the base; the feeding path is arranged on the base; the calibration device, the feeding device, the cutting device, and the bending device are consecutively arranged along a first axis, wherein the first axis is horizontal with respect to the ground; the feeding path is arranged along the first axis; the calibration device comprises two calibration mechanisms each comprising a processing channel having an individual size; the two calibration mechanisms separately calibrate two kinds of pipes having different diameters; the position switching mechanism is adapted for adjusting positions of the two calibration mechanisms and aligning one of the two processing channels with the feeding path; the feeding device comprises two feeding channels having different sizes; the two feeding channels are adapted for transporting the two kinds of pipes, respectively; the first position switching assembly is adapted for aligning one of the two feeding channels with the feeding path; the bending device comprises two bending channels having different sizes; the two bending channels are adapted for bending the two kinds of pipes, respectively; the second position switching assembly is adapted for aligning one of the two bending channels with the feeding path; the position switching mechanism, the first position switching assembly, and the second position switching assembly are independent from one another; and operations of the position switching mechanism, the first position switching assembly, and the second position switching assembly are independent from one another.
