Since the oxide scale contains iron, when the first magnetic member 5 is energized, the first magnetic member 5 can adsorb the oxide scale through magnetism, and the three first magnetic members 5 cooperate to adsorb the oxide scale to the edge of the upper surface of the lower anvil 4.

Referring to fig. 2 and 3, the bottom of the lower anvil 4 is provided with an accommodating cavity 42, and a lifting assembly for driving the three first magnetic members 5 to sequentially lift and descend along the direction away from the vertical center line of the lower anvil 4 is arranged in the accommodating cavity 42.
