Description

Technical Field

[0001] The present invention relates to the technical field of shock-absorbing spring electroplating, and specifically relates to a surface electroplating device and an electroplating process for high-strength anti-fatigue shock-absorbing springs. Background Art

[0002] High-strength anti-fatigue shock-absorbing springs are elastic elements designed specifically for long-term dynamic loads and frequent impact conditions. Their core characteristics are high fatigue life and strong impact resistance. They are mainly used in the fields of automobiles, heavy machinery, and vibration equipment. During the production of shock-absorbing springs, in order to improve the overall performance of the shock-absorbing springs, surface electroplating treatment is usually carried out on the shock-absorbing springs. Therefore, a surface electroplating device for shock-absorbing springs is required. However, the current electroplating devices still have the following deficiencies: For example, the patent document with the publication number CN214881910U discloses an electroplating device for spring production. In this electroplating device for spring production, by moving the second fixed block, the slider slides on the second chute, and at the same time, the second clamping block is fixed inside the clamping groove. In this way, the clamping groove of the device can effectively surround the outer surface of the rotating shaft loaded, and the spring can be effectively fixed for electroplating. However, during the electroplating process, the electroplating solution is prone to precipitation, which affects the electroplating efficiency and quality. Summary of the Invention

[0003] The purpose of the present invention is to provide a surface electroplating device and an electroplating process for high-strength anti-fatigue shock-absorbing springs to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A surface electroplating device for high-strength anti-fatigue shock-absorbing springs includes a fixed bottom plate and a circulation component. On the upper surface of the fixed bottom plate, an electroplating seat is installed. An electroplating mother groove is opened at the left end inside the electroplating seat, and an electroplating sub-groove is opened at the right end inside the electroplating seat.

The impurities in the electroplating solution are fully intercepted and filtered through the double filtration of the first filter screen and the second filter screen. At the same time, open the drain valve to discharge the filtered electroplating solution in the electroplating mother-tank through the connecting outlet pipe and then enter the electroplating sub-tank through the connecting inlet pipe.
