The invention discloses a full-automatic saw-blade cutting machine, relates to blanking equipment, and aims to solve the problem that the manual feeding operation is required for a common cutting machine. The full-automatic saw-blade cutting machine comprises a rack and a cutting device arranged on the rack, wherein an automatic feeding device is arranged on one side of the rack, and comprises a supporting frame, a transverse frame, a gripping mechanism and a pushing mechanism; the transverse frame is fixed on the supporting frame; the gripping mechanism is slidably connected to the transverseframe; the pushing mechanism is arranged on the supporting frame and used for pushing a bar to the cutting device; supporting rollers used for supporting the bar is rotationally connected onto the supporting frame; and a driving mechanism used for driving the gripping mechanism to perform reciprocating linear motion along the direction perpendicular to the length direction of the supporting frame. The full-automatic saw-blade cutting machine has the following advantages and effects: through the automatic feeding device, the bar can be automatically gripped, and then the gripped bar can be conveyed to the cutting device for being cut; the whole bar feeding and cutting process is automatically achieved through mechanical arms, so that the manual feeding process can be eliminated; and consequently, the bar feeding efficiency can be improved.
