Thermal insulation aluminum alloy profile surface protection pretreatment process

Abstract

The invention provides a thermal insulation aluminum alloy profile surface protection pretreatment process. Protection pretreatment of the surface of a thermal insulation aluminum alloy profile is completed through cooperation of a treatment basket, a scrubbing unit, a dust suction pump, an oil brushing unit, an electric sliding block, a supporting set, a driving motor and a clamping unit. The thermal insulation aluminum alloy profile surface protection pretreatment process can solve the main problems that when the surface of the aluminum alloy profile is subjected to protection treatment, a,metal chippings on the outer wall of the aluminum alloy profile are attached to the surface of the profile, and the surface of the profile is of a rectangular structure; during manual cleaning, the consumed time is long, and the arms of workers are easily punctured by metal chippings; b, manual oiling protection treatment on the outer wall of the aluminum alloy profile is prone to causing oil liquid dripping, the oiling quality of the outer wall of the profile is affected, and oil liquid waste is extremely likely to be caused; and the outer wall of the sectional material is manually oiled unevenly.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, in particular to a surface protection pretreatment process for heat-insulating aluminum alloy profiles. Background technique [0002] Aluminum alloy profiles are the most widely used non-ferrous metal structural materials in the industry, and have been widely used in aviation, aerospace, automobiles, machinery manufacturing, ships, construction, decoration and chemical industries. With the rapid development of science and technology and industrial economy in recent years, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also in-depth. [0003] Before the aluminum alloy profile is used for welding, it is necessary to carry out protective pretreatment on the surface of the aluminum alloy profile, but there are mainly the following problems in the protective treatment of the surface of the aluminum al...

AI Technical Summary

Problems solved by technology

[0003] Before the aluminum alloy profile is used for welding, the surface of the aluminum alloy profile needs to be protected and pretreated, but the surface of the aluminum alloy profile mainly has the following problems: a: The metal debris on the outer wall of the aluminum alloy profile adheres to the surface of the profile, The surface of the profile is a rectangular structure; manual cleaning not only takes a long time, but also the metal debris can easily hurt the staff's arm; b: Manual oil protection treatment on the outer wall of the aluminum alloy profile is likely to cause oil dripping and affect the outer wall of the profile The quality of the oil coating is high, and it is easy to cause waste of oil; and the manual oiling of the outer wall of the profile is not uniform
