Description

Technical Field

[0001] The invention relates to an electroplating hanger, and in particular to a vertical electroplating conductive hanger installation structure, in particular to a hanger used in the operation of electroplating hard chromium or nickel-chromium on a hydraulic cylinder piston rod. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics.

[0003] There are different types of electroplating hangers according to the shape of the parts, coating technical requirements, electroplating process and equipment size. For example, there are differences between automatic lines and manual lines. Usually, electroplating workshops have universal hangers suitable for various common parts and special hangers designed and made for certain parts. There are many types of universal hangers, suitable for a variety of processes and parts.

[0004] During the electroplating process of the hydraulic cylinder piston rod, especially the electroplating of piston rods with larger diameters and lengths, due to the material and connection structure of the piston rod electroplating tooling, the electroplating process resistance is relatively large, and the current density is generally set in the range of about 25-35A / dm². Higher current density will lead to increased voltage during the electroplating process, resulting in a large amount of power loss. In addition, quality feedback such as electric shock often occurs at the connection of the electroplating tooling.

[0005] The existing conductive hangers for vertical electroplating of piston rods generally adopt the form of conductive hanger + threaded transition tooling or conductive hanger + slip tooling to ensure the versatility of product structure. To ensure design strength, the conductive hanger is generally made of carbon steel or a combination of copper + carbon steel. To meet the applicability of multiple product categories, tooling design strength and convenience of tooling material sourcing, threaded transition tooling and slip tooling are generally made of carbon steel directly.

[0006] Although this conductive hanger + threaded transition tooling or conductive hanger + slip tooling meets the applicability of multiple categories of products and the strength of tooling design, the selection of tools and the design defects of the conductive structure of the tools also cause the problem of poor conductivity during the use of the tools. The resistance of the electroplating process is large, and it is difficult to break through the current density due to the rated voltage limit of the electroplating power supply. Even if a higher current density is used, it will lead to the problem of increased voltage during the electroplating process, which will cause a large amount of power loss. In addition, quality feedback such as electric shock often occurs at the connection between the electroplated product and the electroplating tooling. Summary of the invention
