A kind of aluminum alloy profile surface protection treatment system and protection treatment method

Abstract

The invention relates to a surface protection treatment system and a protection treatment method for aluminum alloy profiles, comprising a bottom plate, a support frame, an upper mold device, a lower mold device and a clamping device. A support frame is installed on the top of the bottom plate, and the support frame is L-shaped. structure, the upper mold device is installed on the inner end surface of the upper end of the support rod. 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 occur during the process and cannot be completely eliminated, resulting in the loss of protective effect of the protective film, reducing the efficiency and utilization rate of the protective film. At the same time, the end of the protective film cannot be reprocessed, resulting in the protective film being easy to The end of the protective film appears to be lifted, peeled off, etc., which reduces the service life of the protective film and other problems.

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...

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
