Description

technical field [0001] The invention relates to the technical field of aluminum profile production, in particular to a semi-closed tubular aluminum profile heat treatment device. Background technique [0002] In order to obtain the final finished aluminum profile, it is necessary to heat-treat the aluminum profile obtained after extrusion molding. The quality of the heat treatment directly affects the quality of the finished aluminum profile, including the pros and cons of compression resistance, tensile resistance and its internal structure. stability, such as the Chinese patent announcement No. 202786341U, which announced the quenching condensate water jacket for extruded aluminum profiles, which is used for cooling the aluminum profiles after heating in the heat treatment process, so as to achieve rapid cooling and obtain ideal crystal phase structure to avoid Common defects such as cracking, but this kind of device lacks a heating process that can effectively cooperate ...

Problems solved by technology

[0005] In the above technical solutions, the heat treatment is mainly aimed at the semi-closed tubular aluminum profile, and the positioning track is mainly used for the positioning of the outer opening of the semi-closed tubular aluminum profile, so that The entire aluminum profile can also be effectively positioned and transported stably. In addition, although the aluminum profile produced from the extrusion die has a high temperature, due to turnover and heat transfer, the temperature and the temperature cannot meet the requirements. Good heat treatment conditions, and the stability of each part is quite different. If the cold treatment is carried out directly, it will cause great damage to the aluminum profile itself, and the physical properties or internal structure will be affected, especially for tubular aluminum profiles. The internal heating device of the profile starts to heat the hollow structure inside the aluminum profile, and evenly transfers heat from the inside to the outside of the aluminum profile, and then starts to heat the outside of the aluminum profile through the external heating device of the aluminum profile, and transfers heat to the aluminum profile evenly from the outside to the inside, The heat treatment temperature of the aluminum profile is suitable and the temperature of each part is basically consistent. After cooling by the cooling device, various physical properties of the semi-closed tubular aluminum profile can be effectively improved, and a very ideal crystal phase structure can be formed to achieve a stable internal structure. , to avoid problems such as cracking
