Aluminum profile quenching system and quenching method

Abstract

The invention provides an aluminum profile quenching system. The system comprises a quenching table, a nozzle assembly, a water pump, a water groove, a ball valve controller, a temperature measuring unit, an operation panel and a control unit. The quenching table transmits and quenches aluminum profiles, and the nozzle assembly is arranged on the periphery of the quenching table and sprays water mist to the aluminum profiles; the water pump and the water groove are connected with the nozzle assembly through a pipeline and provide a water source; the ball valve controller is arranged between the water pump and the nozzle assembly, and can adjust the water mist spraying speed and / or flow of the nozzle assembly; the temperature measuring unit is arranged on a feeding opening and a discharging opening of the quenching table to detect the first temperature T1 of aluminum profiles obtained before quenching and the second temperature T2 of the aluminum profiles obtained after quenching; the operation panel is used for inputting parameters of the aluminum profiles; and the control unit receives parameters sent by the operation panel and the first temperature T1 and the second temperature T2 sent by the temperature measuring unit and outputs an instruction to the ball valve controller according to the parameters, the first temperature T1 and the second temperature T2 so as to adjust the mist spraying speed and / or flow of the nozzle assembly. Therefore, according to the quenching requirements of different aluminum profiles, the quenching cooling condition can be adjusted in real time, and the profiles are prevented from deforming.

Description

technical field [0001] The invention relates to the field of aluminum profile processing, in particular to an aluminum profile quenching system and an aluminum profile quenching method. Background technique [0002] In the prior art, the strengthening mechanism of aluminum extrusion profiles is mainly on-line quenching, and the general production process is: extrusion-quenching-cutting-straightening-sawing-framing-aging. The effect of quenching directly affects the mechanical properties of the profile. The temperature drop rate of the profile in the quenching section is proportional to the properties of the profile. In the quenching section, the existing general methods are fan cooling and water cooling. Fan cooling is provided by the fan at the profile outlet to cool the high-temperature profile; while water-through cooling is cooling through the water tank when the profile is discharged. Among them, the airflow intensity of the fan in the fan cooling is small, greatly aff...

AI Technical Summary

Problems solved by technology

Among them, the airflow intensity of the fan in the fan cooling is small, greatly affected by the external temperature, and the quenching force is small, so it is only suitable for the production of alloy building profiles with low mechanical performance requirements; while the water-through cooling has a strong quenching force, but because the high-temperature profiles directly enter In water, the temperature drops too fast, and the profile is easily deformed. This method is only suitable for solid products with simple profile cross-section and low shape and position requirements.

Therefore, neither of the above two cooling and quenching methods can meet the requirements of industrial profile products with complex cross-sections and high mechanical properties.
