The present application belongs to the technical field of punch forming, and relates to a packaging aluminum pipe punch forming device. The present application comprises a packaging aluminum pipe punch forming device, which comprises a die and a punch. A die cavity that is matched with the punch is formed in the die. A bar magnet is arranged in the punch. A radially magnetized annular magnet is arranged in the die. The axis of the radially magnetized annular magnet coincides with the axis of the die cavity. When the punch is inserted into the die cavity to punch, a radial repulsive force is generated between the radially magnetized annular magnet and the bar magnet, so that the punch is kept at the central position of the die cavity. The strong repulsive force generated by the same polarity of the radially magnetized annular magnet and the bar magnet can keep the punch at the central position, so as to resist the lateral force that causes the bending of the punch, and effectively prevent the bending and deformation of the punch. Therefore, the wall thickness uniformity and straightness of the formed packaging aluminum pipe are ensured.
