Abstract: Addressing the disadvantages staying with the process of manual punching of headed shell，a modified hydraulic heading anvil with punching function is designed by means of changing the conventional shell-heading device’s material and its structure as composed with upper and lower anvils.Thanks to the modification，two operation steps，i.e.，hot-heading and punching of the shell are combined into just one process，and performed at the same time.Relevant actual operation shows that the said modified heading anvil device is in possession of such advantages as lower operation cost，reduced labor intensity，higher productivity，and more consistent and better formation of the shell head which ensures satisfactory inner surface quality of the pipe.
