The invention discloses an automatic production line for armored doors. The automatic production line comprises a manual feeding position, a multi-station multi-speed chain conveying line and a manualdischarging position; the right side of the manual feeding position is connected to a belt conveying device in a riveted mode; the right side of the belt conveying device is connected to turnover equipment in a riveted mode; the turnover equipment is internally provided with a roller conveying line in an embedded mode; the right side of the turnover equipment is connected to bare board lifting equipment in a riveted mode; the right side of the bare board lifting equipment is connected to a conveying passage in a welded mode; the multi-station multi-speed chain conveying line is arranged in the conveying passage in an embedded mode; and a multi-station operation parallel operation area is arranged on the upper side of the conveying passage. According to the automatic production line for the armored doors, the aging characteristic that feeding and discharging of door sheets can be independently selected is achieved, and therefore the maximum utilization rate of each station can be achieved, the production efficiency of the doors can be improved, the production capacity of the whole production line can be further improved, and the labor cost and the labor intensity of workers can belowered.
