Automatic pipe bender

The invention relates to an automatic pipe bender which comprises a base, a left support, a right support, a speed reducing mechanism, an output torque amplifying mechanism and a pipe bending implementing mechanism. The left support and the right support are fixed on the base, an input end of the speed reducing mechanism is connected with an output end of an electric drill through a first shaft, an output end of the speed reducing mechanism is connected with an input end of the output torque amplifying mechanism, and an output end of the output torque amplifying mechanism is connected with the pipe bending implementing mechanism. The electric drill is taken as a power source, the rotating speed of the electric drill is adjusted to be suitable for pipe bending operations through the electric drill, the output torque amplifying mechanism is adopted to enable a torque force applying point to be extended outwards from the input end of the output torque amplifying mechanism to the output end ...
