Problems solved by technology

[0002] Aluminum alloy extruded profiles require heat treatment process when processing thick ones. However, due to the different lengths of the produced aluminum alloy extruded profiles, the heating methods during the heat treatment process are also different. For ultra-long aluminum alloy extruded profiles, it is difficult to find the corresponding length. Therefore, segmental heating is required. In the existing segmental heating method, due to the large temperature difference between different positions during the heating process, cracks or even fractures are prone to occur at positions with large temperature differences, and there are uneven heating and heat dissipation during the heating process. The problem of heat treatment of aluminum alloy profiles is likely to decrease
[0003] After searching, the Chinese patent application number is CN111334654A, which discloses a heat treatment equipment for super-long aluminum alloy extruded profiles, including heat treatment equipment. Furnace, heat preservation box and water cooling box are distributed linearly from left to right. However, because the above technical solution can only fix the cylindrical super-long aluminum alloy extruded profile with the limit block, there is still a problem that it cannot fix the rectangle or other more complex shapes. The problem of effective heating and fixing of extra-long aluminum alloy extrusion profiles

Abstract

The invention discloses thermal treatment equipment and a thermal treatment method for an ultra-long aluminum alloy extruded profile, and relates to the technical field of thermal treatment of aluminum alloy extruded profiles. To perform thermal treatment on ultra-long profiles of more shapes, the equipment specifically comprises a mounting frame, wherein a first sealing frame is arranged on the outer wall of one side of the mounting frame, a second sealing frame is arranged on the outer wall of one side of the first sealing frame, and a third sealing frame is arranged on the outer wall of oneside of the second sealing frame. The thermal treatment method for the ultra-long aluminum alloy extruded profile comprises the following steps: putting the ultra-long aluminum alloy extruded profileonto a roller on the mounting frame; and pushing the ultra-long aluminum alloy extruded profile to forwards move by a distance which is consistent with length of the first sealing frame. The thermaltreatment equipment is equipped with an electric hydraulic pushing rod, a limiting slot, a supporting block and a side supporting block, and the supporting block can support the ultra-long aluminum alloy of a rectangular structure very well, thus avoiding the deformation problem, caused by softening after heating the ultra-long profile to certain temperature, of the ultra-long profile.
