The invention relates to an intelligent production line for high-speed aluminum bar saw cutting. The intelligent production line comprises a machine body and an operation table used for controlling the machine body to run; the machine body comprises a feeding device used for conveying aluminum bars, a feeding sizing device used in cooperation with the feeding device, a main machine saw cutting device used in cooperation with the feeding sizing device and a discharging device used for discharging after saw cutting is completed. According to the intelligent production line for high-speed aluminum bar saw cutting, monomer project research and development and system organic sets of series functions including batch automatic feeding, numerical control sizing, saw cutting clamping, finished product numerical control stacking, weighing, coding and the like of workpieces are studied, overall process numerical control problems (controllable beat) of a series of motions such as feeding, positioning, clamping, hoisting, weighing and coding are solved, and the production line is worthy of popularization.
