Perno de cizallamiento cola plana

El proceso de estampado en frío es uno de los nuevos procesos de mecanizado a presión de menor o ningún corte
metal. Es un método de transformación que utiliza la deformación plástica del metal bajo la acción de
fuerzas externas y, con ayuda de moldes, redistribuye y transfiere el volumen de metal para formar
las piezas o formatos necesarios. El proceso de estampación en frío es el más adecuado para producir piezas estándar.
elementos de fijación como pernos, tornillos, tuercas, remaches, pasadores, etc.

Flat tail pernos de cizallamiento are specialized fasteners designed to shear off at a predetermined torque or load, protecting machinery from damage by preventing overload. Here’s a detailed description:

Características principales:

1. Flat Tail Design

   • The bolt has a flat or slightly rounded end (as opposed to a pointed tip), making it suitable for applications where a smooth finish is needed after shearing.

   • The flat tail ensures the bolt sits flush or breaks cleanly without protruding.

2. Shear Groove (Weak Point)

   • Contains a pre-machined notch or groove near the head or along the shank, which is the weakest point.

   • This ensures the bolt breaks predictably under excessive force, protecting sensitive components.

3. Material & Strength

   • Typically made from medium-carbon steel, stainless steel, or alloy steel for durability.

   • Heat-treated to precise hardness levels to ensure consistent shear strength.

4. Tipos de cabeza

   • Common heads include hex, flange, or countersunk to fit different applications.

   • Some have a smooth, rounded head to minimize damage if the bolt shears.

5. Tipo de hilo

   • Fully or partially threaded, depending on the application (e.g., securing shear plates in agricultural or industrial equipment).

Aplicaciones comunes:

• Agricultural Equipment (e.g., mowers, tillers, balers)

• Maquinaria industrial (e.g., conveyor systems, gearboxes)

• Automoción y aeroespacial (safety-critical shear points)

• Construction Equipment (shear pins in augers, crushers)

Shear Bolt vs. Standard Bolt:

• Pernos de cizallamiento are engineered to fail at a specific torque, acting as a mechanical fuse.
