Online standing wave quenching device

The invention relates to the technical field of aluminum profile production equipment, and provides an online standing wave quenching device which comprises a quenching table and a cooling mechanism. A conveying structure is erected on the quenching table, baffles capable of moving up and down relative to the conveying structure are arranged on the two sides of the conveying structure, material blocking assemblies are oppositely arranged at the feeding end and the discharging end of the conveying structure respectively, and a standing wave space is formed between the two material blocking assemblies. The cooling mechanism is mounted in the quenching table and comprises an air cooling structure and a water cooling structure, a plurality of air outlet pipe grooves are formed in the air cooling structure, a plurality of water spraying guide pipes are arranged on the water cooling structure, and air outlets of the air outlet pipe grooves and water spraying openings of the water spraying guide pipes face the stand
