Abstract

The invention relates to the technical field of heat treatment of aluminum alloy plates, in particular to a symmetric constraint roller type quenching device and quenching method for a heat treatment reinforced aluminum alloy plate, and the quenching device comprises a plurality of groups of quenching nozzle mechanisms and a plurality of groups of roller way mechanisms. The quenching nozzle mechanisms are symmetrically arranged up and down in the movement direction of the aluminum alloy plate; the multiple groups of roller way mechanisms are symmetrically distributed up and down in the moving direction of the aluminum alloy plate, and the roller way mechanisms and the quenching nozzle mechanisms are alternately arranged at intervals; the roller way mechanism can divide the quenching cooling area into a first high-pressure cooling area, a second high-pressure cooling area and a low-pressure cooling area in sequence in the movement direction of the aluminum alloy plate. According to the quenching device, high-strength and high-uniformity direct quenching can be carried out on the aluminum alloy plate, so that deformation of the aluminum alloy plate caused by internal stress of the aluminum alloy plate due to different cooling rates and different cooling heat flow densities in the thickness, width and length directions during cooling of the aluminum alloy plate is prevented, the cooling strength is enhanced, and meanwhile the service life of the aluminum alloy plate is prolonged. And quenching deformation is also reduced.
