Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating equipment, and in particular relates to a tool used for electroplating hard chromium on a star-shaped dial. Background Art

[0002] Star-shaped dials are used in automated filling lines for functions such as bottle feeding and rotating. Star dials are typically made of steel, while bottles are typically made of glass, steel, aluminum alloy, or plastic. During the production process, the bottles collide and rub against the dial, causing wear and tear on the dial and cosmetic damage to the bottles. The surface of the dial that contacts the bottles is electroplated with hard chrome and then polished. This significantly increases the surface hardness of the dial, enhancing wear resistance and reducing abrasion while also preventing cosmetic damage to the bottles.

[0003] Due to the complex working surface shape of the star-shaped dial, the current distribution on the electroplated surface is uneven during the production process of hard chrome electroplating. The current is large at the protrusions and small at the depressions. It is impossible to ensure that the thickness of the coating on the surface is uniformly deposited, resulting in uneven distribution of the electrodeposition thickness on the electroplated surface of the product, which not only affects the product processing size, but also affects the control of the subsequent polishing process, resulting in low processing accuracy and poor performance of the product.
