The invention discloses automatic material loading, feeding and unloading equipment for bar stock blanking and a method thereof. The equipment comprises a material loading mechanism, a feeding mechanism and an electric cabinet, wherein the feeding mechanism is provided with a mechanical arm, and the mechanical arm is connected with a manipulator. The equipment has the following beneficial effects: 1, the equipment can replace workers in the whole process to realize full-automatic operation of material loading, feeding and unloading, thus the purpose that one worker operates multiple machines can be realized; 2, varieties are convenient to switch; 3, in the feeding process, the manipulator has a function of automatically avoiding a punch die so as to realize multi-row reciprocating operation, especially automatic punching operation of narrow bar stock relatively to the die width; 4, although the structure is installed in front of the punch die, the structure barely affects workers to assemble, disassemble and adjust a die in front of a punch; 5, the shutdown rate of the punch is improved; 6, the equipment has the advantages of simple mechanical structure and low cost and is convenient to maintain; and 7, after material is automatically fed, the bar stock can be subjected to multiple-particle blanking because feeding position is accurate.
