Device for avoiding online quenching deformation of aluminum profile

Abstract

The invention discloses a device for avoiding online quenching deformation of an aluminum profile. The device comprises a water tank (10), wherein the water tank (10) is internally provided with a first driving felt roller (3), a second driving felt roller (9), a first driven felt roller (4) and a second driven felt roller (17); the first driving felt roller (3), the second driving felt roller (9), the first driven felt roller (4) and the second driven felt roller (17) form a channel for allowing an aluminum profile to be quenched to pass through; and the aluminum profile to be quenched is conveyed along the channel by virtue of a frictional force. According to the device, the cooling deformation of the aluminum profile is limited in a roller shaping way, so that the precision required by uniformity control of cooling speed is reduced; in addition, the aluminum profile is quenched by using the felt rollers, and a felt plays roles in protecting and cleaning the aluminum profile, so that the surface quality of the aluminum profile is improved.

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...
