O processo de encabeçamento a frio é um dos novos processos para a maquinagem sob pressão com menos ou nenhum corte
metal. É um método de processamento que utiliza a deformação plástica do metal sob a ação de
forças externas e, com a ajuda de moldes, redistribui e transfere o volume de metal para formar
as peças ou os espaços em branco necessários. O processo de encabeçamento a frio é o mais adequado para a produção de
elementos de fixação, tais como cavilhas, parafusos, porcas, rebites, cavilhas, etc.
A gold-plated safety wire bolt is a specialized fastener designed for applications where both security and corrosion resistance are essential. Here’s a detailed description of its features:
1. Material & Construction
-
Base Metal: Typically made of high-strength steel, stainless steel, or brass for durability.
-
Gold Plating: A thin layer of gold is electroplated onto the bolt’s surface, enhancing corrosion resistance and providing a conductive, aesthetically pleasing finish.
2. Safety Wire Feature
-
Prevents Loosening: The bolt has a small hole (or pair of holes) drilled through its head or shank to allow for safety wire (locking wire) installation.
-
Wire Securing: The wire is threaded through adjacent bolts or anchored to a fixed structure, ensuring vibration-resistant locking.
3. Applications
-
Aeroespacial e aviação: Used in engines, landing gear, and critical assemblies where vibration could loosen fasteners.
-
Military & Defense: Ensures reliability in harsh environments.
-
Electronics & RF Systems: Gold plating improves conductivity and resists oxidation in sensitive circuits.
-
High-End Automotive/Motorsports: Prevents fastener failure in high-vibration conditions.
4. Advantages
-
Resistência à corrosão: Gold plating protects against oxidation and chemical exposure.
-
Conductivity: Useful in electrical grounding or RF shielding applications.
-
Tamper Resistance: Safety wire deters unauthorized removal.
-
Apelo estético: Gold plating adds a premium, decorative finish.
5. Common Standards
-
Military Specs (MIL-SPEC): Such as MIL-W-5041 for safety wire practices.
-
Aerospace Standards (MS, NAS): For high-reliability bolting systems.
- Safety wire bolt gold plated
6. Variations
-
Hex Head, Socket Head, or Pan Head: Depending on torque and space requirements.
-
Different Wire Hole Sizes: Typically 0.8mm–1.2mm for standard safety wire.
