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.
Pan head shear bolts are specialized fasteners designed to break away at a predetermined torque, protecting machinery from overload damage. Here’s a detailed description:
Características principales:
-
Head Style:
-
Pan Head – A slightly rounded, low-profile head with a flat bearing surface for even load distribution.
-
Designed to sit flush or slightly above the surface when installed.
- Pan head shear bolt
-
-
Shear Mechanism:
-
The hex or drive head shears off once the bolt reaches its specified torque limit, leaving a smooth shank to prevent disassembly.
-
Used in tamper-proof and safety-critical applications.
-
-
Materials:
-
Typically made from hardened steel, acero inoxidable, or corrosion-resistant alloys for durability.
-
May include coatings like zinc plating o galvanization for extra protection.
-
-
Thread Type:
-
Usually fully threaded or partially threaded (depending on application).
-
Common thread standards: Metric (M) or SAE (UNC/UNF).
-
-
Drive Types:
-
Hex drive (Allen key) – Most common for shear bolts.
-
Torx or Phillips – Less common but used in specific applications.
-
Pan head shear bolt
-
The drive shears off after installation, leaving no way to remove the bolt without drilling.
-
-
Aplicaciones:
-
Security fastening (e.g., traffic signs, public fixtures).
-
Overload protection (e.g., conveyor systems, gearboxes).
-
Aerospace & automotive (where tamper resistance is critical).
