The invention relates to the technical field of T iron machining, and provides a high-property T iron punching device for a loudspeaker. The high-property T iron punching device comprises a base and further comprises a controller, a loading mechanism, a punching mechanism and a discharging mechanism. The loading mechanism comprises a placing table and a first absorbing assembly, the punching mechanism comprises a rotating disc, a driving assembly and a drilling assembly, the discharging mechanism is arranged on the other end of the top of the base in a through manner to discharge drilled T iron, the discharging mechanism comprises a conveying belt and a second absorbing assembly, the second absorbing assembly is slidingly arranged beside the rotating disc, the conveying belt is arranged onthe end, away from the top of the placing table, of the base, and the first absorbing assembly, the driving assembly and the second absorbing assembly are electrically connected with the controller.According to the loudspeaker high-property T iron punching device, the T iron punching operation space is maximized, the punching efficiency is improved, the yield is increased, meanwhile, it can be effectively ensured that the T iron is not damaged by too large drilling strength, and the T iron quality is ensured.
