Description

Technical Field

[0001] The utility model relates to the technical field of shaft pin processing, in particular to a chrome-plated tooling component for shaft pin processing. Background Art

[0002] Axle pins are generally cylindrical or conical in shape, and their material and strength vary depending on the application scenario and the load-bearing structure. Pin connections are widely used in the mechanical field. During the pin processing process, to improve the pin's performance, it is usually chrome-plated. Chromium is a bright white metal with a slight bluish tint. The process of applying a layer of chromium to metals or certain non-metals through electrolysis or chemical methods is called chrome plating. By depositing a thin, hard layer of chromium on the metal surface, it improves the workpiece's wear resistance, corrosion resistance, aesthetics, and service life.

[0003] For example, the utility model with application number CN202122144611.1 discloses a chrome-plated tooling assembly suitable for axle pin processing. The chrome-plated tooling structure similar to the above application currently has the following shortcomings: it is only applicable to axle pins of a single size, and the axle pin cannot be centered when it is fixed, resulting in the axle pin and the scraper being unable to effectively correspond when scraping, which in turn leads to poor scraping effect and easily affects the chrome plating of some areas of the axle pin.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a chrome-plated tooling assembly for shaft pin processing is proposed. Utility Model Content
