The utility model relates to a self-resistance heating electromagnetic riveting device which comprises a self-resistance heater used for conducting self-resistance heating on a rivet and two electromagnetic riveters arranged on the left side and the right side of the self-resistance heater respectively, and the self-resistance heater comprises two electrode punches abutting against a to-be-formed rivet head and a rivet cup head of the rivet respectively. The two electrode punches are connected with the positive electrode and the negative electrode of a high-frequency pulse current generating power source respectively, the ends, away from the rivets, of the electrode punches are fixedly connected with amplifiers of the electromagnetic riveters located on the same sides of the electrode punches through double-end studs, and the electromagnetic riveters push the electrode punches to move towards the rivets subjected to self-resistance heating through the amplifiers. The device is reasonable in design, rivets are
