Numerical control pipe bending equipment for inhibiting bending pipe from becoming elliptic

The utility model discloses numerical control pipe bending equipment capable of restraining a bent pipe from becoming elliptic, which comprises a machine frame, an automatic feeding and transferring device, an anti-wrinkle mechanism, a supporting mechanism, a die clamping device and a die bending mechanism, and the automatic feeding and transferring device, the anti-wrinkle mechanism, the supporting mechanism, the die clamping device and the die bending mechanism are installed on the machine frame. The supporting mechanism comprises a plurality of movable joint pressing blocks, and every two adjacent movable joint pressing blocks are hinged to each other. Semicircular grooves are formed in the right end faces of the movable joint pressing blocks, and the semicircular grooves in the movable joint pressing blocks are matched to form a first semicircular groove; according to the technical scheme, the outer side wall of the bent part of the catheter can be sufficiently supported, so that the ovality of the bent p
