One-time punch formed aluminum hose whose head can be broken and used as plug

A one-time punch formed aluminum hose whose head can be broken and used as a plug, comprising an aluminum hose, wherein one end of the aluminum hose is sequentially provided with an extrusion head and a plugging head, and a broken part is provided between the extrusion head and the plugging head, wherein the end of the extrusion head facing the plugging head is provided with an extrusion port, the end of the plugging head away from the extrusion head can be in an interference fit with the extrusion port, and wherein the extrusion head, the broken part and the plugging head are all integrally formed with the aluminum hose;

• wherein the plugging head comprises a plugging cylinder and a plugging disk, which are connected in sequence, with the plugging cylinder being integrally formed at the upper end of the plugging disk, and the broken part being integrally formed at the lower end of the plugging disk;
• wherein the outer diameter of the plugging cylinder progressively increases from the direction close to the plugging disk;
• wherein the end of the plugging disk away from the plugging cylinder is defined with a weight reduction groove;
• and
• wherein the broken part is of an annular tubular structure, with the upper end of the annular tubular structure being integrally formed with the bottom of the plugging disk, and the lower end of the annular tubular structure being integrally formed with the extrusion head.
