Zusammenfassung:	The invention relates to the technical field of machining, and provides a cold heading manufacturing method for a connection bolt of an ignition switch. The method includes the steps that according to the wire diameter and the name needed during machining of the connection bolt, a material of a predetermined length is cut; cold heading is carried out on a semi-product of the connection bolt so that a head portion and a pole portion can be formed, and an arc face, a notch and a bottom end face of the head portion can be formed; the pole portion of the semi-product of the connection bolt is squeezed and threaded so that threads can be formed, and a finished product of the connection bolt is obtained. The invention further provides a connection bolt cold heading die based on the cold heading manufacturing method. Product quality problems are solved and production cost is reduced.
