Shear bolt tapered tail

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.

Tapered tail shear bolts are specialized fasteners designed to fail at a predetermined torque or shear load, protecting machinery from overload damage. Here’s a detailed description:

Caraterísticas principais:

1. Tapered Tail Design

   • The bolt has a conical (tapered) section near the head or along the shank, which creates a stress concentration point.

   • This taper ensures controlled shearing under excessive force, preventing damage to connected components.

   • Shear bolt tapered tail

2. Shear Functionality

   • Engineered to break at a specific shear load, acting as a mechanical fuse.

   • Commonly used in power transmission systems (e.g., augers, conveyors, PTO shafts) to protect against jams or overloads.

3. Materials & Strength

   • Typically made from medium-carbon steel or alloy steel, heat-treated for consistent shear strength.

   • Some versions are zinc-plated or coated for corrosion resistance.

4. Tipos de cabeça

   • May feature hex heads, flange heads, or other drive styles for easy installation.

   • Often marked with grade identifiers (e.g., “Grade 2” or shear load ratings).

5. Aplicações

   • Agricultural machinery (combine harvesters, tillers).

   • Industrial equipment (conveyors, crushers).

   • Automotive and aerospace systems requiring overload protection.

   • Shear bolt tapered tail

Vantagens:

• Prevents costly equipment damage by shearing before mechanical failure occurs.

• Easy replacement post-failure, minimizing downtime.

• Precision-engineered shear points ensure reliability.

Normas comuns:

• DIN, ISO, or OEM-specific specifications for dimensions and shear strength.
