An aluminum profile online combined quenching device

Abstract

The invention discloses an aluminum section online combined quenching apparatus. The apparatus comprises a frame, an upper cooling system, a lower cooling system and a side cooling system, the upper cooling system comprises a plurality of upper water cooling nozzles, the lower cooling system comprises a plurality of lower water cooling nozzles, the side cooling system comprises a plurality of side water cooling nozzles, each of the upper water cooling nozzles, the lower water cooling nozzles and the side water cooling nozzles is connected with a water supply device through a water tube, the water tube is provided with a waterway control system for controlling the water pressures of the corresponding upper, lower and side water cooling nozzles, and all the waterway control systems are controlled by a PLC programmable controller. The water pressures of all the water cooling nozzles are controlled by individual waterway control systems, and parameters are set through the controller, so the water pressure adjustment of all aluminum sections is realized individually, the apparatus is suitable for processing different aluminum section products, and uniform cooling and cold deformation prevention of the aluminum section are realized.

Description

technical field [0001] The invention relates to an online combined quenching device for aluminum profiles. Background technique [0002] With the wide application of aluminum profiles in the fields of industry, transportation, etc., the quality and mechanical properties of aluminum profiles are getting higher and higher. The existing water-cooling quenching and air-cooling quenching equipment can only unilaterally carry out online water-cooling quenching or air-cooling. Cold quenching cannot meet the requirements of different cooling and quenching methods for online extrusion of different aluminum profiles. [0003] At present, the commonly used water-cooling and quenching methods are "super-water cooling" or spraying. The cooling intensity is not high enough to break away the water mist formed on the surface of high-temperature aluminum profiles, thereby reducing the quality of quenching. In addition, when spraying and quenching , the water pressure is adjusted up or down ...

Problems solved by technology

[0002] With the wide application of aluminum profiles in the fields of industry, transportation, etc., the quality and mechanical properties of aluminum profiles are getting higher and higher. The existing water-cooling quenching and air-cooling quenching equipment can only unilaterally carry out online water-cooling quenching or air-cooling. Cold quenching cannot meet the requirements of different cooling and quenching methods for online extrusion of different aluminum profiles

[0003] At present, the commonly used water-cooling and quenching methods are "super-water cooling" or spraying. The cooling intensity is not high enough to break away the water mist formed on the surface of high-temperature aluminum profiles, thereby reducing the quality of quenching. In addition, when spraying and quenching , the water pressure is adjusted manually or automatically as a whole, which cannot meet the water pressure requirements of different parts of the asymmetrical aluminum profile, resulting in uneven cooling and serious cold deformation

[0004] At present, the commonly used air-cooling quenching method is to install air-cooling devices on the upper and lower sides of the aluminum profile conveying device, and then the left and right sides of the aluminum profile will cause uneven cooling and severe cold deformation.
