A heat treatment process for semi-closed tubular aluminum profiles

Abstract

The invention discloses a semi-closed tubular aluminum profile heat treatment process in the technical field of semi-closed tubular aluminum profile heat treatment. Step 1: Put the semi-closed tubular aluminum profile into a heating device and heat it to 290-300°C. After the heating is completed Carry out natural cooling and cool it down to room temperature; Step 2: put the above-mentioned cooled semi-closed tubular aluminum profile into the heating equipment again for heating, heat it to 500-600°C, and keep it warm for 1 hour, then quickly Put it into water for cooling; the present invention realizes unobstructed fixing of the tubular aluminum profile by setting a power unit, a tubular aluminum profile clamping mechanism and a heating unit, and then realizes 360° heating without dead angles, ensuring that the entire tubular aluminum profile is heated evenly , to ensure that the heat treatment effect of the tubular aluminum profile can reach a better state.

Description

technical field [0001] The invention relates to the technical field of heat treatment of semi-closed tubular aluminum profiles, in particular to a heat treatment process for semi-closed tubular aluminum profiles. Background technique [0002] Aluminum alloy heat treatment technology is to select a certain heat treatment standard, control the heating rate to rise to a certain corresponding temperature when heat treating aluminum alloy products, keep it for a certain period of time, and cool it at a certain speed to change the structure of the alloy. [0003] The invention case of heat treatment of partially closed tubular aluminum profiles is disclosed in the prior art, and the Chinese patent application number of the invention patent is 201810667912.2, including: support rods, support feet, heat treatment furnaces, auxiliary rods, protective covers, rotating shafts, connecting plates , the cross-section of the support rod is a rectangular structure and is horizontally attach...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a heat treatment process for semi-closed tubular aluminum profiles, to solve the problem that the two ends of the semi-closed tubular aluminum profiles are clamped by clamps during the heat treatment of the semi-closed tubular aluminum profiles in the prior art proposed in the background technology. However, during the heat treatment, this part was not heat treated, and at the same time, because the flame injection device was located on the top of the semi-closed tubular aluminum profile, the bottom of the aluminum profile was not heated, which in turn caused the entire semi-closed tubular aluminum profile to be heated unevenly. The effect of heat treatment is not ideal
