Description

Technical Field

[0001] The invention relates to the technical field of spring blackening, in particular to a method for processing a high-temperature and high-elasticity corrugated spring of an aero-engine. Background Art

[0002] Spring blackening is an important metal surface treatment process, which forms a dense oxide film on the surface of the spring through a specific chemical reaction. First, the spring is pre-treated by degreasing and pickling, and then the spring is placed in a solution composed of sodium hydroxide and sodium nitrite and heated (generally around 130-160°C) for oxidation, and then the spring is completed after cleaning, hot water cleaning, saponification, oiling and other processes. The room temperature blackening method is a newer technology with advantages such as low energy consumption. The treatment process requires the use of blackening tanks, heating devices and other equipment, and quality inspections such as appearance and corrosion resistance are required after treatment. This process has good anti-rust performance, beautiful appearance and low cost, but it should be noted that the spring surface pretreatment should be thorough, the process parameters should be strictly controlled, and the equipment and solution should be regularly maintained to ensure the quality and effect of the spring blackening treatment, meet the various requirements of the spring in use, extend its service life and improve its appearance and performance.

[0003] The Chinese patent with publication number CN118390037B discloses a blackening device for surface anti-rust treatment of flat wire spring parts, aiming to solve the technical problem that the existing blackening device for surface anti-rust treatment is not efficient when used for flat wire spring parts. The invention comprises a base. A rotating mechanism is arranged on the support plate of the base. A reduction motor, a rotating shaft and a rotary carrier are arranged on the mounting chassis of the rotating mechanism. The rotary carrier is provided with a plurality of mounting holes. Rust removal and oil removal tanks, rinsing tanks, clear water tanks and blackening treatment tanks are sequentially installed on the mounting holes. The invention enables the blackening process to be carried out continuously, reduces waiting time and downtime, and significantly improves production efficiency. The invention provides a corresponding locking and clamping mechanism and a uniform oil spraying mechanism for the special shape structure of the flat wire spring parts, so that the blackening treatment efficiency of the flat wire spring parts is improved while improving the blackening treatment quality, which is conducive to new progress in the field of blackening. The device used in the processing method for blackening springs in the prior art generally puts oil removal and rust removal together for treatment and then drains. However, rust removal generally uses an acidic solution to react with rust to remove rust, while oil removal generally uses an alkaline solution to saponify and emulsify grease to remove oil stains on the surface of the spring. If oil removal is performed without cleaning after rust removal, the residual rust removal liquid (usually containing acidic substances) will not only continue to corrode the surface of the spring, destroy the surface quality of the spring, and reduce the accuracy and performance of the spring, but will also react with the oil removal liquid to neutralize, which will not only consume the effective ingredients in the oil removal liquid and reduce the oil removal effect, but may also produce salt precipitation. If the cleaned spring is not dried, for the spring after blackening treatment, moisture will cause the black oxide film to peel off and discolor, and good blackening effect and appearance quality cannot be guaranteed.
