Porca de barril de ameixa de cabeça plana

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 flat head plum porca de barril (também conhecido como porca de barril ou pear-shaped nut) is a specialized type of fastener designed for specific applications where a low-profile, secure, and often concealed connection is needed. Here’s a detailed description:

Caraterísticas:

1. Shape & Design:

   • Flat Head: The top surface is flat or slightly countersunk, allowing it to sit flush with or below the material surface when installed.

   • Plum/Barrel Body: The nut has a rounded, barrel-like (or pear-shaped) body with internal threads.

   • Slotted or Hex Drive: Many flat head barrel nuts have a slotted drive (for screwdriver installation) or a hex socket (for Allen/hex key tightening).

2. Material:

   • Normalmente fabricado com aço (often zinc-plated or stainless steel for corrosion resistance) or latão for decorative or non-magnetic applications.

3. Installation:

   • Designed to fit into a pre-drilled or recessed hole, providing a low-profile fastening solution.

   • Often used in furniture assembly, automotive panels, machinery, and electronics where a flush finish is desired.

Utilizações comuns:

• Furniture & Cabinetry: Used in flat-pack furniture for hidden joints.

• Setor automóvel e aeroespacial: Securing panels or components with minimal protrusion.

• Eletrónica e caixas: Fastening internal components without exposed hardware.

• DIY & Metalworking: When a smooth surface is required after assembly.

Vantagens:

• Low-profile finish (flush with the surface).

• Strong grip due to the barrel shape distributing load.

• Easy to conceal for aesthetic applications.

Variations:

• Slotted Flat Head Barrel Nut: For screwdriver installation.

• Hex Socket Barrel Nut: For Allen/hex key tightening.

• Shoulder Barrel Nut: Includes a shoulder for added stability.
