Description

Technical Field

[0001] The invention belongs to the technical field of air springs, and in particular relates to a galvanizing device for special-shaped metal parts of air springs. Background Art

[0002] In order to rapidly attenuate the vibration of the frame and body of a passenger car and improve the driving stability and comfort of the passenger car, the suspension system of a passenger car is generally equipped with an air spring assembly. Air springs have advantages that other vibration isolation devices cannot match. The stiffness of air springs can change with the change of load, so the natural frequency is almost unchanged under any load. Air springs have nonlinear elastic characteristics, and their characteristic curves can be designed into ideal shapes. For the same air spring, when the inflation pressure changes, different load-bearing capacities can be obtained. Therefore, one air spring can meet the requirements of multiple loads and has good economic benefits.

[0003] Air springs refer to springs that can be filled with compressed air in a retractable and sealed container and use the elastic effect of air. They are widely used in society. The cover plate is one of the main components of the air spring. In the processing and production of air spring covers, in order to prevent the air spring covers from rusting during long-term use, it is usually necessary to use a galvanizing device to plate a layer of zinc on the surface of the air spring cover plate to provide efficient surface protection for the air spring cover plate. However, the galvanizing devices for air spring covers on the market still have the following problems:

[0004] 1. The existing air spring cover galvanizing device cannot provide protection for workers during the galvanizing process, and high-temperature zinc water can easily splash out and injure people;

[0005] 2. The conventional air spring cover plate galvanizing device is not convenient to adjust the device according to the actual size of the processed cover plate, and the application scope of the device is limited;

[0006] 3. The conventional air spring cover plate galvanizing device has unstable clamping and adsorption of the cover plate, and the cover plate is prone to fall off during galvanizing.

[0007] In Chinese patent literature, there is an invention publication document with publication number CN 114164382 A, entitled "An air spring cover plate galvanizing device". The invention discloses an air spring cover plate galvanizing device, including a galvanizing processing table, an electric control box, an electric telescopic rod and a servo motor. The electric control box is installed at the left front of the galvanizing processing table, a fixed block is arranged on the inner side of the top of the first splash-proof panel, a bearing frame is arranged at the upper rear of the galvanizing processing table, a mounting plate is fixed at the bottom of the electric telescopic rod, and a push rod is arranged below the left and right ends of the mounting plate. In the air spring cover plate galvanizing device, when the mounting plate is controlled to move downward to galvanize the cover plate, the extrusion rod during the downward movement can engage with the internal hole of the fixed block and squeeze the fixed block, so that the first splash-proof panel rotates toward the middle of the device, and under the transmission action of the first conical teeth and the second conical teeth, the second splash-proof panel can be driven to rotate in the same direction, and the upper end opening of the galvanizing processing table can be reduced, which can provide a protective function for the staff and prevent the high-temperature zinc water from splashing and injuring people.
