Numerical-control pipe bending equipment control system capable of restraining bent pipe from becoming oval

The invention discloses a numerical-control pipe bending equipment control system capable of restraining a bent pipe from becoming oval. The numerical-control pipe bending equipment control system comprises a rack as well as an automatic feeding and transferring device, an anti-wrinkling mechanism, a supporting mechanism, a clamping die device, a bending die mechanism and a control assembly which are mounted on the rack; the control assembly comprises a controller, a first position sensor and a second position sensor; the controller is used for controlling a second semicircular groove to be matched with a fourth semicircular groove so as to clamp a guide pipe, controlling a first semicircular groove to be matched with a fifth semicircular groove so as to clamp the guide pipe, controlling the automatic feeding and transferring device to push the guide pipe to move forwards, and controlling a clamping die and a bending die to rotate around the central axis of the bending die so as to bend the guide pipe.
