Description

Technical Field

[0001] This invention relates to a standing wave cooling system for reverse extrusion, belonging to the technical field of aluminum profile production equipment. Background Technology

[0002] With the widespread application of aluminum profiles in industry and transportation, the requirements for their quality and mechanical properties are becoming increasingly stringent. In existing technologies, the strengthening mechanism of aluminum profiles mainly involves online quenching, with the specific production process being: extrusion – quenching – cutting – straightening – sawing – framing – aging. The quenching effect directly affects the mechanical properties of the profile; the rate of temperature decrease during the quenching stage is directly proportional to the profile's performance. Currently, existing quenching methods generally include fan cooling and water cooling. Fan cooling uses a fan at the profile outlet to provide airflow to cool the high-temperature profile; while water cooling involves passing the profile through a water tank during discharge.

[0003] Current water-cooled quenching devices have insert plates at both ends of the water tank, with inlet and outlet ports respectively on the insert plates at both ends. Aluminum profiles enter the water tank through the inlet port for quenching and cooling, and then exit through the outlet port. The water level in the tank is relatively low, the water circulation volume is small, and the cooling effect is poor. In addition, the direct spraying of cooling water onto the high-temperature profiles can easily cause the profiles to deform, affecting the final quenching quality.

[0004] Patent application number 202011414063.3 discloses a standing wave water-cooled online quenching device, which includes a water tank, a support frame inside the water tank, a conveyor roller conveyor on top of the support frame, and standing wave nozzles on both sides of the conveyor roller conveyor, with the front and rear nozzles arranged opposite each other and the nozzle orifices facing inwards and upwards. This eliminates the need for a baffle plate, increases the water level in the water tank, and increases the total volume and circulation of cooling water, effectively ensuring the final cooling effect. However, the above-mentioned quenching device relies solely on the nozzles to create a water seal effect. Although this can prevent water from overflowing from the water tank to some extent and increase the water level, the water level is still not ideal, failing to effectively guarantee the final cooling effect, and the large water consumption significantly increases production costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a standing wave cooling system for reverse extrusion, which is an improvement over the prior art. The standing wave nozzle is provided with an end water seal, which, together with the standing wave nozzle, can form a good water seal effect on the water tank, thereby effectively preventing water from overflowing from the water tank, increasing the water level in the water tank, ensuring the final cooling effect, and reducing water consumption and saving production costs.

[0015] Optionally, water baffles are provided on the left and right sides of the roller frame, and the water baffles are located at the water-blocking step position.
