Aluminum alloy profile surface protection treatment system and protection treatment method

Abstract

The invention relates to an aluminum alloy profile surface protection treatment system and a protection treatment method. The aluminum alloy profile surface protection treatment system comprises a bottom plate, a supporting frame, an upper die device, a lower die device and a clamping device; the supporting frame is arranged at the upper end of the bottom plate; the supporting frame has an L-shaped structure; and the upper die device is arranged on the inner end face of the upper end of a supporting rod. The aluminum alloy profile surface protection treatment system can solve the problems in existing equipment that a protective film is liable to bulge or fall off because the right-angle position of the inner surface of aluminum alloy cannot be stuck tightly when the protective film is stuck on the surface of the U-shaped aluminum alloy profile, the protective film loses the protective effect and the sticking efficiency and use rate of the protective film are reduced because bubbles cannot be eliminated completely in the sticking process as well as the service life of the protective film is reduced because the tail end of the protective film is liable to warp and fall off in the useprocess of the protective film caused by the fact that the tail end of the protective film cannot be treated again.

Description

technical field [0001] The invention relates to the technical field of profile surface treatment, in particular to an aluminum alloy profile surface protection treatment system and a protection treatment method. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing Increase, aluminum alloy profile is a kind of profile produced and processed based on aluminum alloy. It has the characteristics of corrosion resistance, plasticity and high strength, and is usually widely used in construction, machinery manufacturing and other fields. [0003] At present, when pasting the protective film on the surface of the U-shaped aluminum alloy profile, there are usually the following deficie...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that when the existing equipment is pasting the protective film on the surface of the U-shaped aluminum alloy profile, the right angle of the inner surface of the aluminum alloy cannot be stuck tightly, and the protective film is prone to bulge or fall off. Bubbles are easy to appear during the process and cannot be completely eliminated. Bubbles are easy to appear after the pasting is completed, which leads to the loss of protective effect of the protective film and reduces the efficiency and utilization rate of the protective film. At the same time, the end of the protective film cannot be reprocessed, resulting in During the use of the protective film, the end of the protective film is prone to warping and falling off, which reduces the service life of the protective film and other problems
