A device for preventing deformation of aluminum profile on-line quenching

Abstract

The invention discloses a device for preventing online quenching deformation of aluminum profiles, which includes a water tank (10). The water tank (10) is provided with a first active felt roller (3) and a second active felt roller (9). A driven felt roller (4) and a second driven felt roller (17), the first driving felt roller (3) and the second driving felt roller (9) and the first driven felt roller (4) and the second driven felt roller (17). The two driven felt rollers (17) form a channel through the aluminum profile to be quenched, and transport the aluminum profile to be quenched along the channel through friction. The present invention uses a shaping roller method to limit the cooling deformation of the aluminum profile, which reduces the accuracy required for uniformity control of the temperature cooling rate; and uses a felt roller to quench the aluminum profile. The felt has a protective and cleaning effect on the aluminum profile, improving the surface quality of the aluminum profile. .

Description

technical field [0001] The invention belongs to the technical field of aluminum profile processing, in particular to a device for preventing aluminum profile from quenching and deforming on-line. Background technique [0002] In the prior art, how to quench the aluminum profile to obtain a product with superior performance and high dimensional accuracy, the prior art cannot control the cooling intensity in sections, and the problem of quenching deformation cannot be solved when processing special aluminum profiles. [0003] At present, the common online quenching methods for aluminum alloy profiles mainly include wind quenching, water mist quenching, water immersion quenching, high-pressure water spray quenching and combined quenching. The cooling speed of wind force and water mist quenching is low, it is difficult to meet the requirements of quenching strength, and the cooling speed is difficult to control; although the cooling speed of water immersion and high-pressure wat...
