There are many ways to realize the movement of the limiting member 11 relative to the supporting member 10, including providing an elastic element such as a spring in the limiting member 11, providing a sliding rail between the limiting member 11 and the supporting member 10, and so on. Preferably, the movement of the limiting member 11 relative to the supporting member 10 is realized by arranging an elastic element such as a spring in the limiting member 11, so that the limiting member 11 can move relative to the supporting member 10 under the action of the abutting end 200 of the jacket 20, and reducing the protruding height of the limiting member 11 relative to the supporting surface 100 until the protruding height is close to 0 or equal to 0, so that the bottom of the aluminum tube is deformed under the action of the extrusion force of the jacket 20, and the aluminum tube with a formed bottom is obtained. Then, after the abutting end 200 is separated from the limiting member 11, the acting force of abutting against the limiting member 11 disappears, the limiting member 11 is reset under the action of the elastic element, protrudes out of the supporting surface 100 again and carries out positioning limitation on the aluminum pipe after bottom forming, so that the aluminum pipe after bottom forming is prevented from falling off.

Specifically, the protruding height of the limiting member 11 protruding from the supporting surface 100 can be adjusted according to the size of the aluminum tube, so that on one hand, the aluminum tube can be better limited, and on the other hand, the size of the bottom of the aluminum tube after being formed can be controlled.
