The invention discloses a vertical type stepping quenching system for a saw blade matrix. The vertical type stepping quenching system comprises a quenching tank, a quenching medium, a vertical type stepping pushing device, the saw blade matrix, a heating furnace and a saw blade matrix flattening device and a cleaning tank which are arranged behind the quenching tank, wherein the quenching tank is arranged at an outlet of the heating furnace; discharge tables are arranged behind the cleaning tank; and manipulator operation devices which can slide along the devices are arranged above the discharge tables from the outlet of the heating furnace. According to the vertical type stepping quenching system, the saw blade matrix is always in the vertical state in the processes of heating, quenching, flattening, cleaning, assembling and disassembling the large-scale saw blade matrix, so that the integral processes of heating and quenching the saw blade matrix are easy and smooth, automated operation is easy to realize, the labor intensity of operators is reduced, labor cost is saved, and the quality of the saw blade matrix is improved greatly. Simultaneously, the integral heating and quenching are performed in a closed system, so that pollution is reduced, ambient environment is improved greatly, and the health of the operators is ensured.
