Description

Technical Field

[0001] The invention relates to the technical field of buckling rings, and more specifically to a method for preparing a corrosion-resistant high-yield strength air spring buckling ring. Background Art

[0002] The air spring is filled with compressed air in a sealed container, and uses the compressibility of gas to achieve its elastic effect. The air spring has ideal nonlinear elastic characteristics. After the height adjustment device is installed, the vehicle height does not change with the increase or decrease of the load. The spring stiffness can be designed to be lower, and the ride comfort is good. The air spring oil is composed of multiple parts, and the buckle ring is one of them.

[0003] Most of the buckling rings in the prior art are made of 20 steel, and then are made through a series of processes such as grinding, heat treatment, electroplating and salt spray testing. The production process is relatively complicated and the cost is high. In addition, during the grinding process, the grinding is not sufficient and comprehensive, which takes a long time, and debris is easy to splash. The subsequent cleaning is troublesome, which increases the burden on the staff and has a poor grinding effect. Summary of the invention

At the same time, with the help of the driving deflection mechanism and the fixed adsorption mechanism, the multiple supporting rods support and fix the clamping ring. During the grinding process, the two grinding rollers comprehensively grind the inner wall, upper and lower ends and edges of the clamping ring, reducing the operation of grinding one by one, shortening the grinding time, and improving the grinding efficiency. The exhaust fan's exhaust and the adhesion of the adhesion layer discharge the heat generated during the grinding process to the outside, reducing the influence of high temperature on the clamping ring, and adsorbing the splashing debris to move in its direction, so that it is adhered to the adhesion layer, so that the debris is not easy to splash around, which is convenient for subsequent cleaning and enhances the use effect.

[0006] 2. Technical solution
