The invention belongs to a corrugated tube port corrector, and in particular discloses a corrugated tube port magnetic-pulse precision corrector. A pedestal is orderly provided with a magnetic collecting block and a press plate, and the pedestal, the magnetic collecting block and the press plate are fixedly connected; a center hole of the pedestal is provided with a core mould inside; the core mould penetrates the magnetic collecting block and the press plate; clearances are reserved between the core mould and the magnetic collecting block and the press plate; the side wall of the magnetic collecting block is provided with a notch; the inside of the notch is plugged with an insulating sheet in the same shape as the notch; the outside of the magnetic collecting block is wound with a coil with an insulating layer; a connecting section of two terminal leads of the coil is the bare coil; insulating blocks are arranged on the connecting section of the two terminal leads; and the insulatinglayers are arranged on lead-out sections of the two terminal leads. The device can correct corrugated tube ports made of various materials, improve the roundness of the corrugated tube ports, precisely shape the shapes of the ports, provide good condition for the subsequent welding of corrugated tubes and connectors, and process high-precision corrugated tube products.
