Description
Technical Field
The invention belongs to the technology of metal surface treatment and processing, and relates to a chemical milling solution and a chemical milling method for a sheet aluminum alloy part.
Background
The chemical milling and washing is widely applied to metal or alloy parts such as magnesium, aluminum, titanium, copper, iron and the like, but different milling solutions are required to be configured for parts made of different materials due to different material properties and performance requirements of the parts, milling process parameters such as solution formula, temperature, time and the like are strictly controlled, otherwise, the structure, shape and surface quality of the parts are uncontrollably influenced, and the parts are scrapped.
In 2010, a forming process of a certain type of chemical milling part, published in a scientific and technological paper of the young academic society of aviation, introduces a process method of forming a part and then chemically milling the part within a quenching period, namely a one-step forming method, and carries out technical analysis on the phenomenon of hammer marks on the surface of the certain type of part, and analyzes that the reason of the hammer marks is that the formed part is corrected by a hammer. Meanwhile, an improved method is provided for the reason of the hammer mark generation. However, the authors propose that some defects still exist, because the chemical milling allowance is manually cut after the chemical milling of the three-dimensional part, the manual cutting labor amount is large, the labor intensity is increased, the overall dimension of the part is ensured by manual filing, and how to reduce the manual work amount is a problem that needs to be discussed in the method, and the quality problem that occurs when the chemical milling of the skin with large chemical milling depth is not solved.
2012, "double-sided corrosion process for milling large-sized wallboard parts of a certain airplane", published in the young science and technology forum of the Chinese society of aviation, introduces a corrosion rate comparison test, a roughness comparison test and an intercrystalline corrosion test, mainly studies the influence of double-sided corrosion on corrosion rate, roughness and intercrystalline corrosion tendency at different temperatures, finds out control elements of the large-sized wallboard part milling processing through a simulation chemical milling test, and studies the influence of turning times on the thickness uniformity of large-sized and deeply-corroded parts. However, the method mainly aims at double-sided chemical milling, the test depends on a simulated chemical milling test, because influence factors are complex in the chemical milling process and the control variable difficulty is high, the simulation test and the actual operation come and go, the temperature influence analysis is not clear enough, a specific temperature interval is not obtained, and because double-sided chemical milling is adopted, difficult chemical milling pieces of a Z9 series machine in our factory are single-sided chemical milling, the turnover frequency adopted in the literature is not completely applicable to the aluminum alloy chemical milling parts or the practicability is poor.
CN101122025A discloses an aluminum alloy chemical milling solution and a milling method thereof, which provides a formula and a process of the aluminum alloy milling solution, wherein the components of the milling solution comprise sodium hydroxide, sodium sulfide, triethanolamine, ethylenediamine tetraacetic acid, sodium sulfate, industrial pure aluminum, deionized water and the like. The method mainly aims to obtain better surface roughness, generally requires that the milling depth reaches 5mm, cannot be applied to sheet aluminum alloy parts (the thickness of the sheet aluminum alloy parts is smaller and generally less than 5mm), and is difficult to eliminate the problems of size over-tolerance, step difference, defective edges, leakage corrosion, wrinkles and the like of the sheet aluminum alloy parts.

During chemical milling, the parts are subjected to rotary chemical milling four times in a clockwise or anticlockwise mode, and the chemical milling area with the largest area during the last chemical milling is located at the bottommost end by selecting the initial chemical milling area and mode.
