Abstract

The invention discloses an aluminum profile quenching device, comprising a water tank, a felt roller, a stock mould, a temperature sensor and a PID (Proportional Integral Differential) controller, wherein the water tank is provided with a water inlet pipe and a water outlet pipe, each of the water inlet pipe and the water outlet pipe is provided with a control valve, the felt roller is arranged in the water tank and used for receiving aluminum profiles to be quenched, the stock mould is arranged at the upper part of the felt roller and comprises an inner cavity, a nozzle connected with the water inlet pipe is arranged between the stock mould and the water tank, the temperature sensor is connected with the stock mould, and the PID controller is connected with the temperature sensor and the control valve arranged on the water inlet pipe and is used for receiving a temperature signal sent by the temperature sensor and regulating the opening of the control valve on the water inlet pipe. The aluminum profile quenching device is capable of adjusting cooling rates and cooling stages of different positions according to the section sizes and materials of different profiles, so that the nonuniformity of temperature distribution is reduced and further the uniform structure properties of the profiles are ensured. Due to existence of the stock mould, the degree of freedom of displacement on a cross section is limited and further the deformation defects are reduced.

Description

technical field [0001] The invention belongs to the technical field of aluminum profile processing, and in particular relates to a device and method for preventing on-line quenching and deformation of aluminum alloy profiles during extrusion. Background technique [0002] Quenching treatment is an important process in the processing of aluminum profiles. The traditional aluminum profile quenching process uses an off-line quenching furnace to achieve quenching treatment, so the energy consumption rate is high and the production cycle is long. On-line quenching technology has the advantages of reducing energy consumption, shortening the production cycle, improving production efficiency, and reducing costs, and has emerged in recent years. If the cooling rate of each part is different during the online quenching process of the profile, it will cause deformation defects such as warping and twisting of the profile, and the faster the cooling rate, the greater the temperature diff...
