Core rod head for copper pipe production

The utility model discloses a core rod head for copper pipe production, which belongs to the technical field of copper pipe production equipment and comprises a core rod head main body, a mounting seat is fixed at one end of the core rod head main body, a plurality of groups of mounting holes are arranged on the mounting seat, a mounting cavity is arranged in the mounting seat, and a motor is arranged in the mounting cavity. A set of correction mechanism composed of the motor, the heat insulation seat, the screw rod, the screw block, the motor, the correction plate and the guide rod is arranged in a traditional core rod head, after a copper pipe is machined, the motor drives the screw rod to rotate through the heat insulation seat, then the screw block drives the correction plate to move in the core rod head under the action of threads, and in the moving process, the correction plate moves in the core rod head. And meanwhile, when the core rod head deforms due to high temperature, the correction plate can res
