A special-shaped copper strip manufacturing method is characterized by comprises the following steps that (1) uncoiling is conducted, specifically, a copper blank strip is provided; (2) high-speed hammer forging is conducted, specifically, high-speed hammer forging of the copper blank strip is conducted through a forging press, and a special-shaped strip blank is obtained; (3) on-line annealing isconducted, specifically, internal stress is relieved through induction heating, isothermal annealing and strip cooling; (4) surface cleaning and washing are conducted, specifically, the surface of the special-shaped strip blank are cleaned and washed continuously, a cleaning agent is sprayed at the same time, and surface burrs, copper scale and foreign matter are treated; (5) rolling is conducted, specifically, a finished special-shaped strip product is rolled through a cold rolling mill; and (6) coiling is conducted, specifically, the finished special-shaped strip product is coiled on a material collection plate. The special-shaped copper strip manufacturing method is high in production efficiency and good in surface smoothness, size precision and mechanical performance.
