The invention relates to a riveting method, which comprises the following steps: firstly, two metal elements to be riveted are pretreated by utilizing the prior machining method of punching or lathe processing, and a gap is formed on a riveted point of the two metal elements to be riveted; and secondly, pressure is applied on the riveted point of the two metal elements to be riveted through combined punched riveting, so that the two metal elements mutually extrude and fill up the gap to form firm connection. The riveting method adopts the two-step method of combining pretreatment by the priormachining method and filling of hollow cavities and expanded angles, and performs the pretreatment of certain shape on the metal elements to be mutually riveted by utilizing the prior machining method of punching or lathe processing first; after the riveted point is formed, the combined punched riveting is used to make the two metal elements provided with the hollow cavities before combination mutually extrude influenced by punching and fill up the hollow cavities to form a reversely suspended locking mechanism which is partially filled or fully filled, so the aim of firm riveting is achieved.
